How to paint mdf furniture white? How to paint mdf at home What paint to paint mdf

How to update the kitchen if there is not enough finance to purchase a new headset? Options: buy new facades, order the company's craftsmen, or repaint the furniture in a different color with your own hands. How to paint kitchen facades to avoid bitter disappointments? What is the difficulty of independently recreating a beautiful coating: high-quality painting of furniture with your own hands is feasible only after thorough long-term cleaning of the old decorative layer. If the removal of paint and varnish residues is done carelessly, the surface of the furniture acquires an unsightly appearance: sagging, streaks, peeling of paint and varnish appear on an uneven surface.

The paint has ennobled the kitchen set

But it is not only insufficient processing that can spoil the beauty of the kitchen facades. Another mistake is the choice of decorative paint for individual items without considering the combination with the interior. Imagine what a careless look you get if you repaint the furniture of the French Provence style, giving lavender or milky-cream languor and tenderness, into bright orange or poisonous scarlet shades. Motley cabinets, decorated with old vignettes, carved shelves, and lattices literally hang over you with an intoxicating weight. Therefore, before starting work, it is important to calculate all the nuances: the materials from which the kitchen is made, the selection of paints and varnishes, the definition of the interior style.

Features of processing materials for kitchen facades

Most of the budget furniture sets are made of chipboard, fiberboard, MDF. Each coating, before painting the furniture, needs preparatory cleaning in different ways. Let's consider the main pre-processing methods.

MDF facades

The coating material for cabinets and countertops made of MDF is a layer of polished veneer, film, plastic or enamel.

How to remove veneer

According to the instructions, lubricate the surface with a thick or liquid compound that dissolves the polish.
After some time, clean the softened wet layer in the direction of the wood grain with a spatula.
Remove the rest of the coating with special iron wool, or with a grinding machine.
First clean the surface with coarse-grained, followed by fine sandpaper.
Clean dust thoroughly.

To remove the film, you will need a construction hair dryer, with hot exposure the coating will go away. Then wash off the glue, degrease, clean, as described earlier.

You can not remove plastic surfaces, but paint the furniture with auto enamel.

MDF elements are very popular among headsets, so learning how to paint them is very useful

Particleboard facades

Chipboard boards have a less durable structure than MDF, therefore, when processing the coating, sparing preparations for wood, a hair dryer, or abrasive abrasive paper are used. Next, degreasing is performed (white spirit, acetone). If the surface layer is not removed, then the area of \u200b\u200bthe facade is simply leveled with fine-grained sandpaper, then cleaned of the dust layer with a damp cloth.

Preparation methods: primer and putty

A prerequisite for beautifully painting MDF and chipboard products is to apply layers of primer to improve the adhesion of the compounds, then putty, to create a smooth surface without cracks and scratches, prime again.

The shades of the primer and filler are matched to the color of the paint, in order to avoid glints of the lower layers and changes in the color scheme.

Application process:

a coat of primer for wood surfaces to see scratches and pits,
acrylic putty,
primer 2 layers.

After the composition has dried, you can proceed to the main operation: paint the facades of the kitchen.

Correct selection of paint composition and quality of tools is of great importance.

Correct preparatory measures before painting are always needed

Methods of painting the surfaces of facades: coloring composition and not only

What paint to choose so that the appearance of the products is flawless, even and smooth?

How is furniture fronts painted?

It is possible to paint chipboard with brushes, spray guns with oil paints, acrylic paints with a water base, alkyd enamels, drying oil, stain, furniture varnishes. The advantages of aqueous formulations are the ability to adjust while they are not dry: change the shade, or dilute the bright color to a delicate shade. But we will get a more beautiful surface using a special aerosol enamel composition.

Painting of MDF facades with plastic is performed using colored enamels for car aerosols. At the same time, painted MDF facades for kitchens are water-resistant, resistant to aggressive detergents and high temperatures, and are durable. Automotive enamel coating guarantees smooth, non-sagging layering.

Instruments

Achieving the ideal kitchen surface with painted facades is impossible without the right tools and aids.

When carrying out the work, you will need the following items.

New brushes, wide and narrow, flat pattern.
Roller made of velor or foam rubber.
Masking tape.
Container for paint.
Rubber spatula.
Gloves.
Soft (lint-free) rags.
Acrylic, oil paint, or alkyd enamel, varnish.

Enamel and acrylic synthetic compound give a shiny gloss, oil paint and stain create a matte finish. Transparent dyes emphasize the beauty of the natural wood structure.

Learn to use a spray gun - it's not difficult

Technique of solid painting of furniture

You can repaint furniture made of chipboard with your own hands with brushes or a roller. Roller spreading saves paint and spreads it more evenly. Decorative patterns should be applied with a brush.

To paint the chipboard with your own hands, movements on the surface are performed in one direction. The final layer is applied along the entire length. Each layer is applied after the first has dried: water composition - after 30 minutes, acrylic - according to the instructions. If it is necessary to differentiate the color or material of the facade, use masking tape. Do not open front doors until dry.

Painted MDF for the kitchen is obtained in the following ways: the dye is selected according to the coating material: for plastic or a wooden surface. When the composition is thickened, dilute according to the instructions.

If you paint the MDF with a roller or brush, then put the initial layer on the prepared area and dry thoroughly.

Then the next layers are applied one, or alternately, with two drying, if the composition has a low hiding power. To achieve a shiny mirror gloss, you can use an alkyd or acrylic clear varnish.

Gloss effect adds personality to furniture

Decorative processing

The creation of an exquisite, beautiful surface is achieved by using additional materials.

The lace pattern is obtained using a stencil - lace tulle.
The technique of creating a relief surface is made using gliza.
Do-it-yourself two and multi-color painting of kitchen facades is carried out by delimiting the area of \u200b\u200bthe product with masking tape, or by applying stencils.
Gold and silver patterns are removed with a thin brush and after applying (drying) a varnish layer.
Artistic 3D painting is performed according to sketches with an airbrush.
Marble surfaces are created, it is necessary to glaze with the selection of the relief structure and drawing veins.
The relief graceful structure of the loach can be drawn with a simple comb.
If you attach a rough canvas or mesh to the surface, you get unique facades for a rustic kitchen.
The use of the bubble wrap allows you to create an embossing that simulates the skin of the aligator.

Painted facades for the kitchen can be painted with thin brushes and artistic paints like Gzhel, in the style of Palekh, to depict picturesque flowers, seascapes, cute faces of cats.

Fantasy is limitless, everyone can choose an element close to their hearts. I wish you success in your pleasant creative endeavors of decorating your home decor with your own hands!

Hello. I know that a similar question has already been asked. But still I will ask. In my kitchen I have MDF panels imitating wood, somewhere in a year or two I'm going to make repairs. In the meantime, I want to paint these panels to refresh the kitchen. There are several questions. Firstly, since this is a kitchen, is it necessary to degrease the panels and with what? Secondly, since the panels "under a tree" do they need to be primed or painted with white paint before painting (I'm afraid it's not a pseudo-tree not to be painted with colored paint)? Thirdly, what paint would you advise to paint? And would you like to know your opinion on painting MDF panels with textured paint? I don't know if she will hold on Thanks a lot in advance for your reply.

Lilia, Krasnoyarsk.

Hello Lilia from Krasnoyarsk!

Already at the dawn of their formation, American auto giants were guided by the principle "not to repair, but to change." That is, it was understood that the produced cars deplete their resource and wear out as much as possible for a certain time. After which, no matter how much the car is repaired, it will "crumble" then some units, then others. What prompted potential customers to buy new cars, and not repair old ones.

MDF panels from the same series. If they are old, where they are cracked, somewhere they are peeled off, worn out, their surface is damaged, then it is easier to replace them altogether than to try to renew them with various paints. No matter how hard you try, it will still be noticeable that they are repainted. You can, of course, try to use ultra-fashionable super-expensive imported paint, but the cost of preparing the surfaces of MDF panels, the purchase of all the necessary components (degreasers, compressor, paints) and the painting itself will exceed the cost of dismantling, purchasing and installing new panels.

/ By the way, when replacing old panels with new ones, it will be possible to use all the attributes of the old panels, that is, beacons on which the previous panels were attached. This significantly reduces installation time. /

Therefore, think seven times whether it is worth resorting to painting old panels. Moreover, the result may not meet your expectations, since imported paint can be produced in the nearest gateway or at Malaya Arnautskaya by enterprising businessmen who have pasted a brand label on an old container.

But if you absolutely decided to do as you said, then try to do the following.

First - first, you should thoroughly degrease the entire surface of the panels. Since all kinds of solvents can damage the surface layer of the panels, since they are made on the basis of aggressive chemical components, it is better not to risk it and use ordinary detergents, the same ones that you use when washing dishes. With the exception of various compositions based on abrasive materials, that is, with the presence of grains.

Textured paints are generally more intended for coating on plaster or on plasterboard plates, but you can also experiment with MDF panels, especially since even in the case of a not entirely successful experiment, one or two years before the main repair that you plan to do, you will be able to endure ...

Before painting, you can apply an acrylic primer to better protect against all kinds of translucency of old panel colors.

Applying textured paint for your case is preferable with a structured roller, and not with sponges or a compressor, especially since not all such equipment have in their arsenal.

But I repeat once again, whoever I asked if they ever painted MDF panels in their kitchens, everyone unanimously asserts that washing is washing, and no one has ever painted to paint. Whether it is your right to listen to the opinion of the majority or do it your way.

Anyway, good luck!

MDF boards of different shades

Is it possible to paint MDF furniture at home, how to paint MDF furniture at home, how to repaint MDF furniture with your own hands and what is needed for this - we will tell below.

Universal enamel KUDO in spray

Coloring compositions for MDF are produced taking into account the characteristics of the material - high absorbency. The correct choice depends on the type of MDF facade coating:

Water-based acrylic enamel and aerosol acrylic auto enamel are suitable for all types of coatings.

Acrylic enamels manufactured by Belinka

Different types of paints for MDF have their own advantages and disadvantages. So, polyurethane compositions have high adhesion to the surface and after drying give a coating resistant to mechanical stress, but they require careful handling during application due to the presence of harmful substances. Oily and alkyd ones dry for a long time and have a strong odor that lasts for a long time. Water-based acrylic enamels are safe, practically odorless and easy to use, but inferior to those listed above in terms of coating strength.

Automotive enamels are designed for metal surfaces, MDF is also suitable for painting

Paints and varnishes for MDF are produced by almost all leading manufacturers and are present in the assortment of most building supermarkets. Glossy, matte and semi-matt options are available for sale, differing in the degree of gloss of the finished product. If you cannot find a special paint for MDF, you can use stains for windows and doors, or for wood.

Necessary materials

Materials and tools for painting MDF furniture

In order to paint MDF furniture at home, you will need:

paint;
primer;
putty;
the solvent corresponding to the selected paint;
masking tape;
covering film.

Depending on the chosen painting method, you will need tools:

sandpaper, mesh and sponge with different grain sizes;
brushes, rollers, spray gun;
narrow and wide spatula;
clerical or construction knife;
screwdriwer set;
protective gloves, goggles, respirator;
clean rags.

It will also take patience and a commitment to performing miracles.

Furniture paint fixtures

Getting Started

Degreasing the treated coating

It is necessary to wash well the painted parts with a sponge soaked in vodka with the addition of detergent to remove dirt and grease. Remove the facades from the body. Remove all handles, glass and curtains. Repair cracks and chips. Any wood putty can be used to seal cracks.

Wood putty will be needed if, after grinding, chips form on the surface of the part

Acrylic is preferred because it is easy to apply, dries quickly and is easy to process. For plastic and acrylic finishes, it is best to use automotive filler. Narrow cracks are cut with the blunt side of a knife before filling. The putty is applied to the places of chips "with a margin", in layers not thicker than 1 mm. Each new layer is applied after the previous one has cured.

Sanding MDF before painting

Elements are carefully polished. Sanding removes excess putty and gives the surface the roughness necessary for better adhesion to the future coating. For sanding, we use sandpaper with a size of 150-180.

Sanding the surface of MDF with a surface grinder

The required shape is given to the putty chips. Better to use an abrasive mesh as it clogs less. It is convenient to use an abrasive sponge in hard-to-reach and embossed places. Sanded facades are thoroughly cleaned of dust with a clean brush and vacuum cleaner.

Primer is the main character

Wood primer sample

This is not an exaggeration. A correctly selected primer not only provides reliable adhesion to the surface to be painted, but also strengthens it, fills in small defects, prevents the pile from raising and reduces the absorbency, significantly reducing the consumption of the coloring composition.

We ground the prepared furniture sections

The most commonly used two-component polyurethane and water-dispersed primer compositions. Aqueous primers are not recommended to be applied over polyurethane and nitrocellulose primers, and it is not recommended to apply polyester paints and varnishes over them. There are no such restrictions for polyurethane primers. When choosing a primer, it is advisable to consult a hardware store consultant.

Applying a primer to the prepared surface

The primer should be applied in a clean, well-ventilated area in several steps. First, it is necessary to prime the ends and relief details of the elements, and then completely the entire element.

Primer application with pneumatic spray

After polymerization of the first layer, the product is cleaned from the raised wood fibers and other small defects with an abrasive mesh or sponge with a size of 220-240.

Small roughness on the surface of MDF or "wood pile"

The sanded surface is thoroughly cleaned of dust and primed for the second time. Re-sanding with 280-300 grit is required before applying the topcoat.

The most crucial stage is painting

Painting MDF panels with a spray gun

The best results are obtained by painting with a spray (spray gun), but not every home craftsman has the necessary equipment at his disposal. You can also use spray paint. The spray applied coating is highly uniform and has a perfect appearance. The difficulties of this method include the need for a separate room, which you do not mind painting at the same time.

You can apply paint with a brush or rollers

If there is no such room, it is better to paint with a brush or a fine-bristled roller. When buying brushes and rollers, be sure to consult with the seller if they are suitable for the selected type of ink composition.

You need to apply paint strictly in one direction, usually in two layers. The second layer is applied only after the previous one has completely dried. It is desirable to arrange the painted facades horizontally. Work must be carried out at a temperature of at least 15 degrees in a well-ventilated area, but at the same time avoid drafts. Be sure to wear a respirator, protective gloves and goggles. Cover with foil what you don't need to paint at all.

Varnish is used for finishing wood surfaces

If a speck or an accidental insect gets on the freshly painted surface, remove them with the sharp tip of a knife. If, after drying, a defect remains in this place, gently sand it with abrasive paper and touch up with a cotton swab with light tangential movements.

The painted surfaces must be allowed to dry completely and only then assembled. Complete drying time is indicated on the packaging of paints and varnishes. You don't have to strive to recolor everything in one go. Better to do it element by element. Then, preparing for painting and repainting the next element, it will be possible to take into account the nuances and correct the mistakes made when working with the previous one. It is important to carry out with the utmost care all the technological operations and manufacturer's requirements for the temperature regime and drying time of primers and coloring compositions.

Polishing the painted surface

The repainting process is quite laborious and painstaking, but the result is worth it. The renewed favorite things delight not only with their modern look, but also with the knowledge that this miracle was created by our own hands.

Painted Polished MDF Board

MDF panels are a building material intended for finishing rooms, cladding facades of cabinet furniture or walls; it is produced from wood chips of low or medium thickness. These parts are considered an environmentally friendly finishing element, since no synthetic adhesives are used in their manufacture, but natural wood resin is used, which reliably fixes all layers of the product and forms a single whole. MDF panels have medium and low density, depending on the number of layers and the composition of the wood. Over time, during the operation of these parts, their surface can get scratches, the coating loses its gloss or has defects, as a result, the integrity of the entire panel is violated, and the appearance of the entire finish becomes unsightly. In this case, any owner is faced with the question: how to update the facade of the panel without completely changing them?

MDF panels on the wall

This article discusses the question of the possibility of painting products such as MDF wall panels, whether it is possible to paint MDF, as well as the process of carrying out such work at home.

There are a number of reasons why painting of MDF panels may be necessary, including:

Mechanical damage to the surface as a result of impact with a sharp object or other material. The top layer of the MDF panel consists of laminated or plain paper with paint applied to it, when exposed to a solid object, the film breaks, which exposes the core of the entire product;
Burnout of paint, loss of color brightness. This deformation results from exposure to ultraviolet rays and atmospheric air, which contains a small amount of moisture. Over time, the coating becomes matte, loses its shine and original appearance;
Temperature changes also negatively affect the external state of the MDF panel surface, since the internal structure consists of wood, which absorbs moisture from the atmosphere and at the same time swells over the entire area. When the temperature rises, the MDF dries up and can crack, besides, the glue contained in the panel loses its capacity from moisture, which leads to paper peeling, lamination and shavings.

MDF and water

These causes of deformations lead to an unsightly appearance of the entire surface and violate the overall design of the wall. If these defects occur, you can paint the MDF panels, having previously done a number of preparatory procedures, but it is worthwhile to understand that painting the parts with your own hands at home brings a result that differs from processing with paints in production.

Painting process of MDF panels

Before answering the question of how to paint MDF panels, you need to understand the composition of this product. MDF board, wall or facade, consists of several layers of pressed paper and sawdust, laminated with a transparent or colored film on the front side. Most often, it is the top layer that undergoes damage and wear, so when planning to update MDF, you need to prepare these types of coatings.

In order to prepare MDF panels for painting at home, you will need:

Sandpaper for surface preparation and removal of gloss or varnish;
Solvent for degreasing the surface from glue and liquid residues;
Dry rags or other lint-free cloth.

These materials are necessary for pre-treatment of MDF panels for painting and for sealing cracks and scratches on the laminate.

Primed MDF panels

All work must be carried out in accordance with the algorithm of actions. The first step is to sand the panel with fine sanding paper, this can be done manually or using a pneumatic tool. It is important to observe the technology of removing varnish, to prevent overheating of the surface or the formation of large scratches on the laminate. The wood-fiber surface is under the decorative film, therefore, when sanding, you need to carefully monitor the thickness of the top layer so as not to erase it through and through. After this procedure, the coating will cease to shine and become rough, slightly cocky.

Next, you need to clean all cracks and chips from dirt and dust, and also clean their edges. All irregularities, if necessary, are rubbed with a special putty, which forms a single whole with the base of the panel, it also needs to be leveled with sandpaper.

After the surface has been processed and leveled, it must be wiped with a dry cloth and degreased with a chemical solvent that will displace and evaporate all the water and wash away dust and dirt.

At the next stage, the topcoat is primed with a special paint, it has a granular texture and can be applied with compressed air or with a simple brush. It can be used to coat the surface in several layers, with intermediate sanding, until the required smoothness is achieved.

Next, the main paint is prepared, tinted and thoroughly mixed so that all the elements are mixed together. You can paint the MDF panels manually or with a special pneumatic gun, but this will require a compressor unit and a moisture-water separator. The composition is applied with smooth movements in two layers: the first - across the main direction, the second - along the entire length of the part. Thus, the formation of smudges and sagging of the paint is prevented.

The final stage will be the processing of the top paper-wood layer of the panel with transparent varnish. This procedure is not necessary, but after it, the surface of the MDF product becomes glossy, its upper layer seems to be updated, and the appearance of the entire structure is restored.

For your information. It is important to observe the intervals for drying the elements between the layers of soil, paint and varnish, as otherwise they will curl up and crack, you will have to carry out all the work again.

Using a spray gun

How to paint and update MDF panels

For MDF panels, you can use alkyd or acrylic enamel, but when choosing a paint it is worth considering the type of primer, the operating conditions of the panels, as well as the composition of the top coat. If this is laminated paper with a synthetic, slightly absorbent film, then it will be advisable to use acrylic or water-dispersion enamel. These materials are environmentally friendly and are perfect for interior painting indoors, while the surface of the panel will be updated, as well as additionally protected from moisture in an aggressive environment.

Thus, subject to the entire staining technology, the question of whether it is possible to paint MDF panels becomes completely solvable at home.

Can MDF panels or facades be painted? Such a process is possible. But it requires compliance with certain conditions, consisting of the choice of materials, preparatory work, the main stages and finishing touches. Painting MDF panels is a task that everyone can do. The only thing that is important to consider is that not all paints are suitable for this purpose, and those that do are not cheap.

Pros and cons of painting MDF

MDF painting is carried out most often for two reasons:

the need to protect the material from negative environmental factors;
decorative purpose - I want to change the color of the MDF board or improve its appearance.

Regardless of the reason for the painting, it has several advantages:

The painted element becomes resistant to high temperatures. This means that when using the MDF panel in the kitchen, it will be possible to put hot dishes on it.
The presence of special additives in the paint allows you to get the facades of the original design: mother of pearl, pearl, metallic.
As a rule, paints intended for MDF do not contain harmful chemicals. This is a big plus, especially if it is planned to stain the material at home.
And finally, painting products can significantly extend their service life.

Of course, MDF staining is not without drawbacks, from which the following can be distinguished:

high price in comparison with a film coating;
the possibility of fading colors under direct exposure to sunlight.

What materials to use?

Since MDF is a material that consists of wood fiber, it can also be painted with ordinary wood paints. However, in order to get a really high-quality result and uniform coloring, you will need special formulations, including:

a primer based on polyurethane;
paint (also polyurethane);
varnish for MDF (if necessary).

Polyurethane enamel does not contain volatile components, can be used both for indoor and outdoor use.

Staining technology

The process of painting MDF with colored polyurethane enamels includes several stages:

grinding;
primer;
directly painting;
drying.

Grinding

For good adhesion of a paint and varnish covering it is necessary to polish the processed products, whether it be facades or wall panels. To do this, use:

dry sandpaper;
scotch-bright - soft, fine-grain abrasive;
ground grinding machines.

If the product is small, then sandpaper based on foam rubber, gradation P220-P280, is used.
For flat surfaces, sanding mats of the 700 series with fine abrasives are used. The same materials will help remove excess soil, fill the risks before painting.

The surface is cleaned, directly on which the paint will be applied. After cleaning, the surface must be degreased with anti-silicone.

Putty

MDF for painting is prepared in a thorough manner, here only by grinding can not get off. If there are visible flaws (cracks, dents), then the surface in these areas must be putty, thereby leveling the surface.

Acrylic hard putty for wood is best suited for puttying. Apply and smooth it with a special rubber spatula.

Primer

For flat products it is better to use the universal white polyurethane primer LBR30. Its high resin content gives it a minimal tendency to shrinkage. Suitable for matte and glossy finishes. For the latter, where every defect is visible on the surface, the preparation requirements are an order of magnitude higher. The best results are obtained by using polyester primers.

Before painting the panels, they must be carefully prepared. Make a working mixture initially. For this you need to take:

lBR 30 primer - 100 parts by weight;
hardener LNB 77 - 40 parts by weight;
thinner LZC 1051 - 10 parts by weight.

All these components must be mixed with each other and the first layer of primer must be applied to the surface to be painted using a pistol with a top tank. Nozzle diameter 1.8 mm, air pressure 2-3 atmospheres. The material consumption should be 120 g per 1 m2. The optimum film thickness is 120 microns. To completely complete the shrinkage process, the soil should be dried within 12 hours.

Before painting the product, it will need to be abraded again. For gloss, an emery tool with finer grain size is additionally used. After that, the surface will be prepared, and the paint for MDF panels can be applied.

In the video: priming and sanding MDF.

Painting

Wall panels can be painted with a brush, roller or spray gun. The room temperature should be about + 20 ° С, the air humidity should be within 50-80%. Can be painted with matte or glossy enamel. But first you need to prepare the working compositions. For matte enamel, take:

100 parts by weight of enamel;
50 parts by weight of hardener;
30 parts by weight of diluent.

For glossy enamel, 70 parts of hardener are taken. The rest of the components in the same amount. For gloss, you should always use a slow thinner to ensure good flow.

Painting MDF panels should be done in a relatively spacious room if they are internal structures (for example, facades or wall elements). The house from the outside should be finished in the warm season. Enamel consumption should be approximately 150g / m2. Medium Density Fiberboard or MDF dries completely in 24 hours.

To obtain a gloss, polish should be done after 3 days. By this time, all polymerization processes will be completed. With the help of special additives on the surface of the product, you can create the effects of mother-of-pearl, metallic, and get corrugated waves.

Wet

You can paint MDF panels with alkyd or polyurethane enamel, as well as powder mixtures. Wet technology involves the use of a sprayer with the appropriate pressure. If the paint is applied in two coats, intermediate sanding is necessary. The layers are no more than 120 microns thick.

Painting surfaces should be free from small debris, dust, insects. In case of their contact, it should be eliminated in a timely manner using a tool such as tweezers. The smudges formed on the painted surface after drying are removed with a clerical knife or fine-grained emery paper.

Powder

Can MDF be painted in another way? Yes, there are special powder mixtures that are sprayed onto the work surface. After that, the product is subjected to high temperatures until the paint is completely melted. This method provides for obtaining an almost perfectly smooth surface.

Powder coating technology involves spraying dry microscopic particles onto a surface.

Drying

You can paint MDF panels by any method. Completes any technological process of finishing drying. It is carried out in compliance with certain conditions:

ambient air temperature no more than 50 ° C;
relative humidity less than 80%.

The duration of the final stage depends on the environmental conditions. It can be from 5 hours to a day. Painted MDF board will dry faster at lower temperatures and air humidity.

Regardless of how it is possible to paint wall panels, observing the steps and conditions of the process will allow you to get a saturated color, a flat surface, save time, costs. It is better to automate all the work using special paint and varnish equipment.

How to paint MDF correctly (2 videos)

What you need for work (20 photos)

Painting MDF boards is a very time-consuming procedure that will require adherence to technology and many rules. It is worth noting right away that such work takes a long time, it may take more than one week. In any case, everything can be done independently, while obtaining the necessary decorative surface.

Why do this?

Many people ask: can MDF be stained at home, and why is this necessary? The answer to the first part of the question will be in the affirmative. Indeed, you can paint the panels with your own hands. But it’s worth mentioning right away: if there is no spray booth at hand, then the result is not always ideal. A staining procedure is necessary for the following reasons:

Ink-coated elements become more resistant to high temperatures and humidity. Therefore, they are allowed to be used in the kitchen and in the bathroom, where they can fulfill different roles.
Through decoration, it is possible to diversify the dull interior, to refresh the look of the room. Hue is selected based on design ideas.
Painting of MDF panels is also necessary in order to extend their service life.

Painting MDF allows not only to diversify a boring interior, but also to extend the life of the product

Of course, this option also has some disadvantages. For example, this procedure is sometimes much more expensive than using decorative films. In addition, the surface is prone to discoloration.

The choice of materials for painting

In principle, all paints for MDF are selected taking into account the composition of the material. And this, first of all, is a fine wood fraction, which means that paint and varnish solutions for wood are suitable for work. But to obtain a really high quality coating, it is advisable to use special mixtures.

When choosing materials for painting MDF, you should pay attention not only to color, but also to the purpose of the paint

Polyurethane Enamels

This material should be preferred for the following reasons:

The coating turns out to be wear-resistant, withstand the effects of household chemicals.
The solution does not have an unpleasant odor, which allows you to carry out work in cramped home conditions.
It is allowed to apply the mixture with a spray gun, roller and brush.
Painting MDF with enamel is done independently, this procedure does not require professional skills.

Naturally, when choosing this material, they pay attention to the manufacturer. This should be a well-known brand, which is sold in specialized stores. When purchasing goods from an unknown manufacturer, it is likely to get a fake.

Advice! If it is not possible to choose a polyurethane composition, then pay attention to alkyd enamels and paints (oil and acrylic).

When choosing a paint, you need to pay attention to the manufacturer

Lacquer

Thus, the question of how to paint MDF panels is no longer a problem. But another dilemma arises - the surface needs additional protection, how can this be done?

Indeed, in order to increase resistance to mechanical stress, to protect against chemical compounds, varnish is used. And for such work, a two-component polyurethane composition that has all the desired parameters is particularly suitable.

Do-it-yourself MDF painting procedure is carried out in several stages. They can be divided as follows:

Grinding.
Putty.
Padding.
Staining.
Varnishing (patina).

The implementation of each stage serves as a guarantee that the result will turn out as it was intended.

Grinding

Work begins with surface sanding. This is a rather laborious activity that must be done carefully.

The panels are sanded with sandpaper with grain size from 120 to 240 units. The process is carried out in several stages and with different materials. Everything must be done very carefully, not staying long in one area. This procedure is carried out in order to remove small irregularities, as well as to remove small pile, which covers the entire surface.

The MDF grinding procedure allows you to get rid of small irregularities on the surface of the plate

On a note! If there are milled sections on the front side, then it is better not to touch them. Chances are good that the sandpaper will smooth out the corners of the pattern.

Puttying

Puttying MDF for painting pursues the goal - to fix existing panel flaws. It happens that when sanding or due to improper storage, cracks or dents appear on the surface. To hide them, putty is carried out. Of course, if there are no such problems, then this stage is skipped.

The technology itself looks like this: the acrylic mixture is carefully applied to the desired area and leveled with a rubber spatula. After drying, be sure to grind.

Padding

Priming the surface of an MDF board is best done with a spray gun, then the primer layer lays evenly

This stage is mandatory. It is conventionally divided into two processes:

Application of the first coat of primer
- This is done with a spray gun, so they prepare the room and place for work. It is better to close the rest of the items in advance with cellophane wrap.
- The mixture is sprayed over the entire surface of the panel in a uniform layer. This is done in order to raise the remaining lint and reduce the absorbency of the base materials.
- Further, when the plate is dry, it is sanded with fine sandpaper.
Coating with the second layer
- The second layer is applied in order to consolidate the result and remove the remaining blemishes.
- Drying should take about a day, after which the primed panel is sanded.

Dyeing

Is it possible to paint MDF with a brush and a roller? Yes, but this should be done very carefully. It is highly likely that streaks and streaks will remain on the surface. Therefore, it is best to use a spray gun.

The technology itself resembles a primer. The paint is applied in several layers, each of which is pre-dried. It is important to achieve an excellent result, so the mixture is sprayed from the milled areas to the edges and then along and diagonally. It is much more convenient to paint smooth panels.

You can use brushes and a roller to paint MDF, but to get an even layer it is better to use a spray gun

On a note! In order to understand in more detail the drying time of the solution and its amount, you must carefully study the manufacturer's instructions. And also select the desired operating mode for the sprayer.

If you want antique

If there is a desire to give the surface a more expressive look, to age it a little, then they resort to patinating. It is advisable to do this when there are drawings and patterns.

Patina is applied in this way:

pass through the selected area with a sponge dipped in the mixture;
leave to dry completely;
the painted area is polished;
proceed to the final stage.

You can create the effect of artificial aging yourself by patinating the surface

Varnishing

The procedure is performed according to the instructions:

The varnish is prepared for use.
The first layer is applied at a rate of about 150 grams per square meter.
After waiting for the first layer to dry well, apply a new layer.
Repeat the drying process.
Final sanding is started. First, sandpaper with large grains is passed over the surface, then finer grains are used. To avoid rolling lumps, spray the area with water.
The panel is left for several days (4 to 7) and polished. For this, it is better to use a power tool.

There are many tips on how to properly paint MDF. The main thing is to follow a clear plan and be accurate.

The corridor is sheathed with MDF panels imitating light wood from floor to ceiling. The thickness of the panels is about 5 mm, I don’t see any film on top, it looks like a regular paper and cardboard layer on top. They covered it up a little with my hands, I decided to wash it with a damp sponge for dishes, rubbed it over here a dozen times and rubbed it to a bright spot in the middle of the wall, well, if it had stopped, it would have been jammed in a couple of places
The first thought is to cover the entire corridor with a stain or varnish, you can slightly darken the color, this is not important. I am inclined to paint with a roller. What can the men use to paint over the worn places and keep the overall color as much as possible. Can varnish with a touch. Can MDF be covered by it? I don’t understand how it happened to me.
Thanks for the tips and all a Happy New Year.

MDF painting is carried out most often for two reasons:

the need to protect the material from negative environmental factors;
decorative purpose - I want to change the color of the MDF board or improve its appearance.

Regardless of the reason for the painting, it has several advantages:

The painted element becomes resistant to high temperatures. This means that when using the MDF panel in the kitchen, it will be possible to put hot dishes on it.
The presence of special additives in the paint allows you to get the facades of the original design: mother of pearl, pearl, metallic.
As a rule, paints intended for MDF do not contain harmful chemicals. This is a big plus, especially if it is planned to stain the material at home.
And finally, painting products can significantly extend their service life.

Of course, MDF staining is not without drawbacks, from which the following can be distinguished:

high price in comparison with a film coating;
the possibility of fading colors under direct exposure to sunlight.

What materials to use?

a primer based on polyurethane;
paint (also polyurethane);
varnish for MDF (if necessary).

Polyurethane enamel does not contain volatile components, can be used both for indoor and outdoor use.

Staining technology

The process of painting MDF with colored polyurethane enamels includes several stages:

grinding;
primer;
directly painting;
drying.

Grinding

For good adhesion of the paintwork, it is necessary to sand the workpieces, whether they are facades or wall panels. To do this, use:

dry sandpaper;
scotch-bright - soft, fine-grain abrasive;
ground grinding machines.

If the product is small, then sandpaper based on foam rubber, gradation P220-P280, is used.
For flat surfaces, sanding mats of the 700 series with fine-grained abrasive are used. The same materials will help to remove excess soil, fill risks before painting.

The surface is cleaned, directly on which the paint will be applied. After cleaning, the surface must be degreased with anti-silicone.

Putty

Acrylic hard putty for wood is best suited for puttying. Apply and smooth it with a special rubber spatula.

Primer

Before painting the panels, they must be carefully prepared. Make a working mixture initially. For this you need to take:

lBR 30 primer - 100 parts by weight;
hardener LNB 77 - 40 parts by weight;
thinner LZC 1051 - 10 parts by weight.

Before painting the product, it will need to be abraded again. For gloss, an emery tool with finer grain size is additionally used. After that, the surface will be prepared, and the paint for MDF panels can be applied.

Painting

You can paint wall panels with a brush, roller or spray gun. The room temperature should be about + 20 ° С, the air humidity should be within 50-80%. It can be painted with matt or glossy enamel. But first you need to prepare the working compositions. For matte enamel, take:

100 parts by weight of enamel;
50 parts by weight of hardener;
30 parts by weight of diluent.

For glossy enamel, 70 parts of hardener are taken. The rest of the components in the same amount. For gloss, you should always use a slow thinner to ensure good flow.

To obtain gloss, polishing should be done after 3 days. By this time, all polymerization processes will be completed. With the help of special additives on the surface of the product, you can create the effects of mother-of-pearl, metallic, and get corrugated waves.

Wet

You can paint MDF panels with alkyd or polyurethane enamel, as well as powder mixtures. Wet technology involves the use of a sprayer with the appropriate pressure. If the paint is applied in two layers, intermediate grinding is necessary. The thickness of the layers is not more than 120 microns.

Powder

Powder coating technology involves spraying dry microscopic particles onto a surface.

Drying

You can paint MDF panels by any method. Completes any technological process of finishing drying. It is carried out in compliance with certain conditions:

ambient air temperature no more than 50 ° C;
relative humidity less than 80%.

The duration of the final stage depends on the environmental conditions. It can be from 5 hours to a day. Painted MDF board will dry faster at lower temperatures and air humidity.
