Types of paints for MDF
It is not necessary, nor is it feasible, to list individual brands. Considering the process of production, we will limit our discussion to paint varieties and their salient features. It is necessary to choose a particular type while considering the MDF plate’s operating conditions, design preferences, and financial constraints. There are many options available in terms of both price and quality.
Type of paints | Brief operational indicators |
---|---|
Water based | The most popular for painting large surfaces have satisfactory performance, completely safe for living. Can be white and color, for internal and external works. |
Acrylic -ilicon | Combine the advantages of acrylic and silicone colors, environmentally friendly product. Inhibits the reproduction of microflora and mosses, have high indicators of resistance to mechanical stress. |
Silicone | Repuls water, are not afraid of moisture and exposure to high temperatures. Surfaces are easily cleaned of dust and dirt. Due to high elasticity, the thermal extensions of the MDF plates are offset without problems. |
Polyvinyl acetate | One of the cheapest ones, recommended for use in rooms with minimal risks of damage. During use, the recommendations of manufacturers should strictly follow, otherwise there are detachment. |
Oil | Traditional dyes, in addition to giving a beautiful appearance, the surfaces effectively protect them from moisture penetration. To increase adhesion, it is recommended to use primers. |
Alkyd | Have a perfectly smooth surface, are made on the basis of alkyd enamels. Plastic, resistant to washing. Disadvantage – under the influence of direct sunlight quickly fades. |
Compute the surface area and buy materials with wiggle room before you buy paint. The manufacturer specifies the consumption. Don’t cut corners if applying a primer coat prior to surface staining is advised. Refusal is caused by paint that is not adhered to MDF stoves well enough. The result is the requirement for costly and time-consuming repairs.

To paint MDF facades in a way that is both long-lasting and aesthetically pleasing, careful consideration of materials and techniques is necessary. Every stage is vital to the finished result, from choosing the best paint that sticks to MDF’s smooth surface to priming the material for improved adhesion and durability. This article addresses preparation techniques to guarantee a smooth application, practical advice for selecting paints appropriate for MDF, and important factors to keep painted MDF facades attractive and long-lasting.
Technology for painting furniture facades from MDF
Work is fairly complex and calls for patience, skill, and attention to detail. are produced in multiple steps, each of which has a substantial impact on the end product’s quality. Painting a facade with a spray gun is much quicker and more effective; if not, use premium brushes with a soft, long-lasting pile.
Traditional and incredibly durable brush to use
The temperature in the room should be at least +20 °C. If the MDF facade is made up of many separate pieces, take into account where they will dry out—racks, supports, etc. Generally speaking, varnishing the plates after painting them is advised because it shields the surfaces from harm, covers minor imperfections, and greatly enhances the design form. The intricate process of lacing calls for specific tools and supplies. We will discuss how to varnish MDF plates later on, but for now, let’s focus on painting.
We’ve already explained how to choose paint by certain criteria. You can only add that the paint color choice for furniture facades should consider the furniture’s function and level of operation.
Step 1: Surface preparation. For furniture facades, sandpaper No. 150–180 must be emphasized in addition to dusting and degreasing surfaces.
Prior to painting, grind MDF.
It is nearly impossible to achieve the desired quality by manual labor over an extended period of time and difficulty. We advise you to use a round grinding unit or a professional electric reciprocating grinder.
MDF’s surface is ground.
Special four-sided lips polish the edges. wearing a respirator while working. The tool should never stop moving while grinding; it should be in constant motion. The following trace must overlap the previous one by at least one-third of its width. It is preferable to go over the area again rather than creating a recess in one spot if trouble spots are still visible. There is no need to press a grinding skin.
Sensible guidance. Fine dust is produced in large quantities during any grinding process. Make every effort to prevent it from falling into nearby rooms.
Step 2: Gently brush off any dust from the surface. Simple brushes are insufficient; a strong vacuum cleaner or compressor is required. Examine the details to see if there are any sharp edges; if so, remove them. IMF lacks strength; its sharp edges will undoubtedly crumble.
Step 3: Apply a primer to the surface. Skilled artisans advise applying two different kinds of primers, twice each. You can apply one coat of primer without waiting for it to dry; move the spray gun horizontally to apply the first layer, then vertically to apply the second right away. Make necessary adjustments to the primer’s amount; the surface shouldn’t have any puddles. The purpose of the first primer is to prevent additional material absorption, and the second is to increase the adhesion coefficient between the materials. Only after the first primer has fully dried is the second applied. 80–100 grams of primer per square meter.
An overview of MDF
Sensible guidance. Novice masters find it extremely challenging to visually determine the consumption. We advise weighing a small piece of MDF on precise weights in order to acquire the skill. After applying a primer, weigh right away. The sample area is then computed, and the weight gain is ascertained. The primitive consumption is calculated with the aid of simple mathematical calculations. Little, add more. Now recall what the optimal layer-covered surface of MDF looks like, and how much primer it will require going forward.
To never attain "factory" quality, we highly advise using a pneumatic sprayer and brush exclusively. Professional villi traces are always detectable. Furthermore, the various angles at which sunlight strikes furniture accentuates every drawback associated with facial coatings. Apply primer to the ends of the structures right away.
Work on the back of the plate only after painting the front if necessary. The manufacturer provides an indication for the drying time, but it is necessary to adjust based on the actual indicators of the room’s microclimate.
Using a spray to apply primer is more practical.
Step 4: Begin grinding the soil with a special sponge. Take the dishwashing cloths, which have sticky tape adhered to the back, if they are absent. This unique substance, which is used for thin grinding, leaves microzarapins on the surface to enhance the adhesion of the subsequent coating in addition to leveling the coating. random motions in different planes. It is advised to only move the sponge in reciprocating motions rather than circular ones.
Spotch Brite sponge
Step 5: Scatter or blow away the dust that has accumulated on the surface. Working with a spray gun is also very convenient because it can be used as a compressor to clean surfaces of dust and be blocked by paint.
Step 6: Begin using a different kind of primer. It enhances the operational indicators of the subsequent coatings and is primarily white. Additionally, you must soil twice when grinding again. Blow off MDF dust once more. The action algorithm is the same as the technology mentioned above.
Putting on the second primer coat
Step 7: Using electric devices with a fine skin, sand the second layer of primer thoroughly. Don’t rush; significant errors will become apparent in the final product. It is highly recommended that inexperienced users practice manipulating unnecessary MDF segments. You will discover how much pressure is needed to bring a grinding skin to the surface, how fast to work, how much MDF can be removed in a single pass, etc. D.
Step 8: Get the paint ready. The manufacturer indicates preparation technology on the packaging.

Observe every advice. We’ve already discussed that a more liquid consistency is necessary for the spray gun to function properly. Apply paint in two transverse directions right away. By now, you ought to be fairly skilled at estimating paint thickness and coating quality. The amount of paint used is 60–180 g.
Bringing a painted surface back to life

Surfaces can be varnished after the coating has dried. This is an essential step for furniture interiors. Not only does varnish provide extra, dependable protection, but it also makes MDF products look much better.

Coating of MDF plates varnish
We’ll explain how to do it below. But there are four key requirements that must be met for quality:
- Do not use cheap varnishes;
- strictly observe the technology;
- have the necessary tools and equipment;
- have a practice of performing complex painting work.
It will become much simpler to work with varnish once you gain the experience of carrying out such tasks and the proficiency to operate tools when applying primer and painting materials. The amount of varnish on the surface can be judged visually, and the spray gun will move "automatically" in the appropriate directions at the ideal speed.
Step 1: Prepare the varnish per the instructions; 100–150 g per square meter is the approximate consumption.
Let the varnish open and combine it.
Start by applying varnish with MDF ends. This technology allows you to reduce the amount of unevenly thickened spots. The final quality is not endangered by the varnish that will spill on the front surface.
The varnish application process using a brush
Use the least amount of abrasive on the first layer once it has dried. Experts advise utilizing abrasive fiber No. 1200, which is classified internationally. You can buy it from specialty stores.
Paper elevator No. 1200
Step 2: Clear the surface of dust. Examine the surfaces in the well-lit room from various viewing angles. Apply a second coat of varnish to the surface; everything should be fine. It should be noted that certain facades require varnishing up to 0.5 mm thick, which will require adding five or more layers. A distinct technology is used in industrial settings, where the sheets are fed into dry chambers via a conveyor belt after the varnish has been instantly applied to the necessary thickness on the surface. One cannot use such technology at home.
Step 3: The finish layer can now be thinly ground and polished because the quality is acceptable. Use Velvet Nos. 1500, 2000, and 3000 for thin grinding. The surface is meticulously processed with each number, and dust is periodically removed.

Sensible guidance. A small amount of water applied to the surface will greatly enhance the grinding quality. The varnish won’t overheat when working on the surface, and the effects of abrasive materials won’t cause microcracks to form. Rays of light are refracted by microcracks, leaving a matte surface.
At least three or four passes through the entire surface are made by each number. The pressing force is marginally lower than when the primer is ground. It takes a long time to grind. If you’re tired, it’s best to carry over your work until the next day rather than stopping altogether.
Polishing is step four. For polishing, you need a perfectly even hard circle and specialized polishing pasta. There is a lot of history; choosing is easy. Examine the suggestions and contrast them with your unique circumstances. Take your time and monitor the surfaces’ lightness at all times.
If your workload is heavy, we recommend investing in specialized electric polishing machines. They greatly enhance the quality of the work in addition to speeding and making it easier. Polishing paste should be applied to the disk in a layer of 1-2 mm; do not smooth it out because any extra paste will automatically come out from under the disk and stay on the MDF surface. Additionally, the revolving disk itself gathers the appropriate quantity of material as needed.

Painting facades of household extensions from MDF
We stated that external skin should not be treated with this material. However, there have been instances where it has been used to temporarily adorn the walls of tiny, historic summer cottages. These owners use a variety of previously used building materials, including MDF panels, for the lining of the facades of their outbuildings because their financial situation prevents them from buying new materials.
In order to increase the life of structures, we recommend that you paint external surfaces. Do not miss the primer, the material is available to all developers at a price, the time is spent a little time, and the effect is obvious. The type of primer, choose the type of paint. On the package, the manufacturer indicates which primer you need to use. The primer is done twice, a brush or roller should move in perpendicular directions. If for some reason this cannot be achieved, then each layer of primer at least at an angle. In addition to an increase in adhesion, the primer reduces the consumption of expensive colors and prevents the appearance of spots coming from the base. Can be painted with brushes of various sizes and rollers. But only rollers can not be done, the joints should be neatly painted with brushes.
Step 1: Calculate how big the painted surface is. Purchase paint while keeping in mind the area and the amount used; do not purchase paint "impetively" and keep supplies on hand at all times. You’ll feel more at ease, and leftovers can always be used to make cosmetic fixes.

Step 2: Use a vacuum cleaner to carefully remove any dust from the MDF’s surface. It is not realistic to remove the dust particles that are visible on the paint’s surface. The stove will need to be completely painted.
Step 3: Get your paint and tools ready. Prior to usage, the composition needs to be well combined if the material was kept in the warehouse for an extended period of time. It will be necessary to dilute the paint slightly with a solvent before using a spray gun to stain the surface. It says on the packaging which one to pick. You can tentatively add a small amount of paint to the solvent for assurance. The solvent is inappropriate if the paint is curled up.

Step 4: Dip the brush or roller into the paint and start painting the surfaces.
Paint can be applied using rollers or brushes.
Sensible guidance. Push the brush all the way down to see streams of extra paint and remove them as soon as possible. You will need to keep going back to the previously covered area for the elimination if you dye the opposite. If you fail to notice them or neglect to come back, there will be an issue. It will take a long time to remove if the flow has dried. In certain instances, they may need to be removed using a knife in order to rectify the coating’s surface.
Step 5: Use a brush to paint the intersection, being careful to remove any villi residue. There are poor-quality painting brushes available in the market, and their supply is inadequate. Before using the brush, rub it vigorously on any clean surface to ensure that it is not left on the surface. Hairs that are not securely fastened will come loose and not cause issues when staining.
Step 6: Depending on the paint’s characteristics, allow the first layer to dry. Expert Malyars advise against drying with windows open because the dust settles in the space and adheres to the paint’s surface.
We use the second layer.
Step 7: Apply the second layer if the first one’s quality isn’t up to par. It uses the same technology.

How to remove the old paintwork
It is not that easy to remove the paintwork; a lot depends on its composition and your skill level. Think about these three methods for cleaning MDF surfaces.
-
Mechanical. Removing coatings is carried out with a metal brush or spatula. The work is very difficult and not always effective. In this way, only very old exfoliated coatings can be removed and then not from the entire surface. It is much easier to use various grinding electric machines with large abrasive material. We warn you that there will be a lot of dust, take measures so that it does not fall into adjacent rooms. To protect the respiratory system, you need to use respirators or masks. Enlargon paper will quickly clog, you will have to change it often.
