Painting materials

Doors made of MDF are products that are preferably installed only inside buildings, as they quickly succumb to external aggressive substances.

It is recommended to use several types of substances as paints for these types of products:

• acrylic varnishes;
• acrylic paints.

These materials are absolutely safe and do not emit toxic substances. The variety of colors of these types of paints allows you to choose them for any type of interior. At the same time, caring for these materials is very easy and simple.

As additional protection, a special primer is used before the paint coat. The amount of materials for painting depends on the size of the door leaf.

To obtain a specific coating color, you must first prepare the paint. For this purpose, special colors are used that allow you to get various types shades.

Painting the door

The process of painting MDF doors is a specific procedure consisting of several successive steps:

1. At the very beginning, the entire surface is primed. This will remove dust from the surface and significantly improve the adhesive properties of the coating.
2. If the surface has some dents, then they are covered with putty. After this, everything is sanded and coated with primer again.
3. The next step is tinting the paint. This needs to be done in one container, since getting the same shade in two “buckets” is almost impossible by eye.
4. At the very end, painting is done. The number of layers is selected individually and depends on the desired appearance of the door.

Doorways are varnished in the same way. If you are using clear varnish, then you need to putty the door with substances that are suitable in structure for your product.

Get more high-quality coating You can use special sprayers that apply paint in an even layer. This not only reduces material consumption, but allows you to obtain very high quality appearance.

If you are painting furniture, you need to disassemble it correctly; it is not at all necessary to completely unscrew the furniture, because you can separate the necessary parts that you are going to paint.

So:

• If the furniture is equipped glass inserts(see), handles, then it is best to remove them, this also applies to other elements of the fittings.

Attention: If we are talking about surfaces that are located near gas burners, for example, then you need to use only fire-retardant paints for metal Polistil.

• First of all, the facade needs to be freed from the old paint coating, the façade must also be thoroughly cleaned of dust and dirt.
• Taking advantage sandpaper, you need to clean the surface thoroughly.
• Now you can apply the primer to the surface, but before doing this, remember to thoroughly shake the composition.

If you want to radically transform your doors, it’s worth checking whether the surface can be lightened. The light canvas fits well into any interior.

MDF doors

How to paint the door?

When manufacturing products from MDF, a special board of compressed or glued chips and wood fiber is used. It is distinguished from fiberboard canvas by its density. If for fiberboard this parameter is considered average, then for MDF it is higher.

Painting the slabs is somewhat difficult due to the fact that the components included in the material have various characteristics. As a result, some areas are easy to paint, while others are not covered by the composition. In order for the updated canvas to acquire an aesthetic appearance, the paint must be:

• No pungent odor. It will not be possible to find a completely neutral composition, but it is still recommended to choose paints with a subtle odor, for example, water-based paints. It is preferable to avoid using nitro enamels or alkyd paints;
• Quick drying. Acrylic and water-based paints have this property;
• With gloss. Matte paint will not work, since on an MDF surface that looks like a sponge, the formed coating will be unaesthetic. You will also need to purchase a varnish designed specifically for MDF. It is first poured into a prepared container to get rid of any air bubbles present. A door coated with varnish can be installed even in the bathroom;
• Highly adhesive. Considering the characteristics of the base, it is important to take care of strong adhesion between the formed coating and the surface. The level of adhesion of the composition is indicated on the packaging;
• With little expense. This will reduce painting costs;
• The right color. The painted door should fit harmoniously into the surrounding interior.

Advice! When determining required quantity paint, remember that you will have to renew the surface of not only the door leaf, but also the frame. To ensure that there is exactly enough paint material, 10% is added to the calculated quantity.

The canvas and the box do not have to be painted the same tone. Depending on the selected stylistic design You can purchase paint of one color for the canvas, and a contrasting color for the box. When choosing, remember that if the surface area to be painted is relatively small, the color will seem a little darker.

How to properly paint an MDF surface?

To ensure you are pleased with the result, carefully prepare for the work, and also follow their sequence. In this case, the finished result will please you and will definitely last for a long time.

Preparing the tool

To start painting, prepare the following:

• Tassels. You will need a narrow brush for small details and a slightly larger one for the canvas. Instead of a larger brush, a roller or spray gun will do;
• Container for mixing paint. Its volume should be sufficient to accommodate all the paint. Especially if you plan to do the tinting manually;
• A mixer or drill with an attachment, which makes it easier to ensure uniform mixing of the composition;
• Working container for paint. Choose a relatively small volume. A special plastic bath is suitable if you decide to use a roller for work;
• Scotch tape, stencils, sponges, if you plan to form a pattern on the door leaf;
• Zero sandpaper.

It is advisable to purchase gloves for yourself. Make sure you have clean rags and solvent to clean up any accidentally falling paint drops. You will need a sufficient amount of paper for the floor and a beam on which to rest door leaf during dyeing.

Preparing the foundation

To MDF doors have acquired an aesthetic appearance, they need to be carefully prepared for painting. To do this, the door is removed from its hinges and completely freed from fittings. If desired, you can subsequently install new handles, locks and hinges. This will further transform the appearance of the door.

The canvas is laid on a beam lying on the floor. Place strictly horizontally to avoid visible drips. The old coating is removed from the surface by heating or using special chemical compositions. The first option is better, as it eliminates wetting and swelling of the wood fiber material

The base is carefully sanded. From use special tool It is better to refuse so as not to damage the material. The removed layers of material are carefully collected. With their help you can prepare putty for MDF. You just need to add some wood glue. This mixture can be used to get rid of defects on the surface of the door leaf. Particular attention is paid to the insertion point of the lock and handle. When using the door, defects always appear in this area that need to be removed.

Let's start painting

First, a primer is applied to the surface to be painted. Before this, the surface is thoroughly dried and dust-free. This will allow:

• Level the surface;
• Reduce paint consumption;
• Increase the adhesive characteristics of the base;
• Form a layer of paint of the same thickness.

Attention! When applying a primer, you will definitely be able to detect defects that were previously invisible.

If defects are found, putty is used to mask scratches, cracks and chips. small size. Then the putty surface is sanded and another layer of primer is applied. After waiting for the primer to dry completely, paint hard to reach places with the thinnest brush.

Then, armed with a roller, spray gun or larger brush, paint the canvas completely. To ensure an even layer, it is advisable to apply another layer of paint.

Attention! Each subsequent layer is applied after the previous one has completely dried. It is better to avoid using fan heaters so as not to deteriorate the quality of the coating being formed.

If you want to paint an MDF door, feel free to get to work! You can even change the color of the door leaf at home. A properly selected composition and properly prepared surface will allow you to quickly achieve the desired result.

After purchasing an apartment or after a certain period of time living in one place, you may want to make cosmetic repairs. If everything is clear with wallpapering, rearranging furniture, replacing flooring, then how to update the door leaves. Not every person knows how to paint interior doors made of MDF.

MDF is a medium density fiberboard. It is made from wood chips, which can be of large, medium, or small fractions. It is pressed using special equipment. To hold the chips together, adhesives (urea resins) are added.

The peculiarities of this material are that due to its heterogeneity, MDF absorbs large number coloring composition. In addition to this, it is necessary to choose high-quality paint, otherwise, under the influence of environmental factors, the decorative layer will become covered with cracks. Due to the addition of urea resins for gluing boards, the environmental friendliness of the material deteriorates. In order not to harm the human body, you need to choose only environmentally friendly coloring compounds.

Required tools and materials

It is important to know not only how to paint, but also how to paint MDF doors at home. Initially, you need to prepare tools, materials, and additional devices that will be useful when carrying out the planned work.

Tools:

1. Brushes. They are necessary for painting inaccessible and patterned areas. The roller cannot catch them. The main thing when choosing brushes is to check the condition of the bristles. It should not crumble or climb during operation.
2. Roller. When purchasing this tool, you need to choose a terry or wool working part. Foam rollers leave empty spaces when painting.
3. Tray for coloring composition or primer. Its size is suitable for applying coloring composition to work surface roller for further work.
4. To stir the paint, you can use any metal stick or electric drill with a mixer.

These were the main tools. You will also need a set of screwdrivers, a screwdriver or a pry bar. They are needed to remove the door leaf. Plus masking tape, scissors, a sharp blade for sealing decorative elements. Stencils will be useful for creating decoration. The question of whether it is possible to paint MDF doors coated with PVC film often arises. In this case, it is necessary to initially make the smooth plastic rough. To do this you need to buy fine sandpaper.

Paint selection

Before you start painting the door leaf, you need to pay attention special attention choice of coloring composition. There are a number of requirements that you need to pay attention to when choosing a coloring composition:

1. Choose paints that smell less. These include water-based compositions.
2. It is important to choose formulations without adding toxic and harmful components to the body.
3. When choosing paint, you need to pay attention to wear-resistant compounds. The doors are used constantly. Not every coating can withstand intense loads.
4. Choose quick-drying paints and varnishes. This is typical for water-based and acrylic paints.
5. MDF has a porous structure, and a matte paint composition will look unsightly on such a surface. The glossy outer layer hides this flaw.
6. The purchased container should say “high adhesion.”

Important! You need to pay attention to paint consumption. Normal indicator 1 kg of paint and primer is considered for a door leaf measuring 2000x800 mm.

You can find various paints in markets, construction and hardware stores. They can all be divided into three groups.

Acrylic enamels

You can find a huge amount color shades. The advantages of acrylic compositions are that they do not emit an unpleasant odor and dry quickly.

Alkyd and alkyd-urethane enamels

These formulations are considered the most popular. Consumers appreciate such paints for low price, wide range of colors. Alkyd compositions have significant disadvantages. They exude bad smell within 3 days after application and takes a long time to dry. Alkyd paints You cannot cover doors to bedrooms or paint anything in rooms where people with allergies live.

Polyurethane enamels

The advantages of these paints are durability and beautiful appearance after application. But high price, toxicity, unpleasant odor are not suitable for all buyers.

Attention! Any kind decorative covering necessary certain time to dry before carrying out further work.

Painting process

When tools, materials, and additional devices are prepared, it is necessary to create a working atmosphere. To avoid staining the floor, you need to cover it with polyethylene. Paper is not suitable for this, as it will become saturated with paint and marks will remain on the surface. When the surface is covered, you can begin to carry out the main work.

Preparatory stage

First of all, you need to remove the door leaf from the hinges. If the door is old, a pry bar is used for this. It needs to be placed on one side under the canvas to create a lever. When pressure is applied to the other side, the canvas will go up and come off the hinges. In new doors, the hinges are fixed to the door with self-tapping screws. You can unscrew them with a screwdriver or screwdriver.

You need two people to remove the canvas. This is due to the large weight of the structure.

You need to clean the door with sandpaper. Sweep away the debris with a brush. Decorative inserts made of metal or glass are sealed with masking tape.

Padding

When the canvas is prepared, it is necessary to apply a primer. It will hide various defects. After applying the composition, you must wait the time indicated on the package. When the first layer has dried, it is necessary to inspect the surface for scratches and cracks. A total of 3-4 layers of primer are needed. This amount will reduce the absorbency rate of MDF.

Painting stage

When the primer has dried, you can begin painting. Hard-to-reach places are painted first. A brush is used for this. The surface is painted with a roller. The first layer must dry before continuing work.

After drying, you need to apply another layer, wait until it dries, and cover the canvas with the outer layer. Finishing layer must be applied carefully. After coating, it is necessary to check the finished surface for defects.

Antique

To age the door, it is necessary to use glaze as a finishing layer. This is a special thinner that can be purchased at the same place where you buy paint. It strengthens MDF structure, draws the structure of the material. The last layer During the work there will be varnish coating.

When the varnish has dried, you need to install the door leaf in place, remove the masking tape and throw out the trash. The varnish will strengthen the paint and protect it from mechanical stress.

To paint an MDF door, you do not need to have any additional skills. It is important to know the features of this material and perform a certain sequence of actions. We must not forget about sanding the canvas with sandpaper and coating it with a primer.

Moreover, this is possible due to the possibilities of the construction market. To do this, you need to buy a primed one (that is, ready for painting). Such a door can be painted well with acrylic paint (which means water based- almost odorless). Acrylic paint applies well to a primed MDF door, even with a brush, and does not leave streaks on the surface, which is very important for the aesthetic appearance of the door.

How to paint MDF doors? How to paint the door?

It is good to apply paint (it’s faster, and besides, paint is saved) and with a brush (a brush is good for convex areas of the door panel).

Apply the first coat to the door surface with a brush. should dry in 15-20 minutes. In this case, you will find a pleasant surprise - the paint is almost odorless. This is due to the fact that the paint is water-based. At the same time, the quality of painting does not deteriorate in any way. Over time, the coating does not fade or fade. The doors can be washed with a damp cloth.

After the first coat of paint is applied to the surface of the door, you will find that the paint has been absorbed into the surface and the door appears unevenly painted. A second coat of paint is required. Perhaps after the second time, the paint will need to be applied a third, final time. And now that’s it, the door is ready.

How much acrylic paint is required for one set of doors?
(the set is: door leaf, frame 5 linear meters, platband 10 linear meters). Based on personal experience: One kilogram of acrylic paint is required for one set of doors.

Where to buy acrylic paint

Acrylic paint is sold wherever residential paint is sold.

Attention: for painting primed MDF doors it is required next paint- WATER-BASED ACRYLIC PAINT FOR WOOD PRODUCTS (WINDOWS, DOORS).

Acrylic paint, intended, for example, for walls, is in no case suitable for MDF doors.

Oil paint is also not suitable, as it does not apply well to the door. It leaves a shine that is unusual for, and there are also stains left on the surface of the door from oil paint.

MDF and wood painting technology

Preparation for painting MDF and wood

The technology for painting MDF doors and furniture (facades) involves preparation, painting and intermediate operations at a temperature of 18-28 ° C, relative humidity air 50-80% and wood humidity 8-14%. The surfaces to be painted, the paints and varnishes used, and the painting equipment must have the same temperature.

Primer, paint and varnish for MDF and wood are supplied ready to be painted and preliminary preparation not required. If tinting paints and varnishes (paint and varnish materials) is carried out independently, you should be guided general recommendations on paint tinting.

Before painting MDF and wood primer, paint and varnish must be filtered through a 50-100 micron filter. The filtering process is mandatory for finishing materials, especially for glossy coatings. If filtered paints and varnishes have been stored for more than two weeks, the paintwork materials should be filtered again before painting.

Wood priming, intermediate sanding
When painting porous wood before application finishing coating Wood and MDF primer should be used. Recommended primer spray parameters: working pressure 2–4 atm., nozzle size 1.6–2.4 mm, wet layer thickness 80-120 µm. Drying of the primer can be carried out in the range from 16 to 60 ° C, while the drying time until ready for sanding is from 6 hours to 30 minutes. When varnishing doors, the first layer of wood varnish can act as a primer layer.

When developing the technology for painting wood and MDF, the optimal test for readiness for sanding is whether the sanding paper is clogged or not. The primer for wood and MDF is designed with the following conditions: manual grinding, and machine, the primer is also ideal for infrared drying. When sanding, do not sand down to the base; if such areas occur, the product should be re-primed.

Painting interior doors

Finishing paintwork is done by air spraying: working pressure 2.5–4 atm., nozzle size 1.6–2.4 mm. MDF paint and varnish are ideal for painting using the HVLP technology (using a spray gun). On request, acrylic paint and wood varnish are supplied as a roller application option, in combination with infrared drying.

Painting (staining) of MDF and wood is carried out in one layer, the recommended thickness of the wet layer is 120-150 microns. For more convenient painting, the door leaf is positioned at an angle of 15-20°; painting in a vertical position also does not cause any particular difficulties.

Drying painted wood and MDF

Drying wood and painted MDF acrylic paint, for maximum productivity and production stability, is carried out at temperatures from 35 to 60 ° C at a relative humidity of 50-80%, drying time is from 1.5 to 2 hours. It is preferable to use a convective drying method. It is recommended to monitor the relative humidity in the dryer; the drying time of aqueous paints and varnishes has a very large dependence on this parameter.

It should be noted that familiarization with the technology of painting interior doors with industrial paint and varnish materials For MDF and wood, drying at room temperature is not recommended. Seemingly easy to use, requires professional painting skills and experience.

Warehousing and transportation

Before storing, painted interior door leaves must be lined with soft paper or packed in individual cardboard packages to avoid friction on the painted surface. It is not recommended to expose painted products to long-term exposure to water and freezing temperatures for the first seven days. Warehousing and storage: 5-25 °C at a relative humidity of 50-80%. Doors can be transported at temperatures down to -25 °C.

Carrying out repairs yourself, and not having enough construction experience, you have to face many problems that you need to solve yourself and make the right decision.

When the question arose about choosing interior doors, the renovation was already coming to an end, and, as sometimes happens, the money allocated for this event was slowly running out. In order to save money, I decided to buy and. The doors are not bad, the only color I wasn’t happy with was hospital white,

We independently make a cheap door into a beautiful and expensive one.

but for the price it was very reasonable. The question was how to paint the door in order to preserve the structure and give the door a normal look. Friends recommended Polish Lakobeits,
We independently make a cheap door into a beautiful and expensive one.

Lakobeits has a liquid consistency, thanks to which the varnish penetrates deeply into the pores of the wood, filling them and forming a thin, uniform, water-repellent layer of varnish. It is also very convenient that the varnish and tone are mixed in one, thanks to this you do not need to first tint and then open it with varnish, saving time and effort.

The technology for applying varnish is very simple. The varnish is applied with a brush, roller, or spray.

The best results are achieved when the varnish is applied with a brush, for several reasons. Doors have a certain panel pattern, and in these places, applying varnish with a spray gun or roller is very difficult to achieve a uniform coating. This can only be done by a highly qualified specialist. The brush is very easy to work with even without specific skills. Before use, Lakobeits must be stirred well, this will ensure uniformity of tone. You need to use a special brush (for varnish). In this brush, the bristles stay in place very well and do not fall out.

The varnish should be applied along the grain of the wood, or structure, in a thin, even layer. When going through the drawing of the panel, you need to be especially careful; smudges may form in these places, which must be removed immediately with a brush.

How better doors should I patch before installation or after? I polished the first door before installation. Place the door on a horizontal surface, being careful not to leak. I will say that the process is very inconvenient. You need to open one side, wait a day, turn it over and open the other side, and then repeat the process again, because the door needs to be coated with two layers of varnish.

I decided to open all the other doors with varnish, when the doors were already installed in the openings with embedded locks and mounted cash, the speed of the process exceeded all expectations.

We independently make a cheap door into a beautiful and expensive one.

Doors prepared in this way can be installed in all rooms. Two layers of varnish provide the door with protection from high humidity and frequent temperature changes. The coating is very durable and practical.

Thanks to Lakobeits, the doors acquired a beautiful and very durable walnut tone. Almost indistinguishable from natural wood.
