How and how to paint a new wooden door beautifully and how to do it

Wood is a demanded material for the production of doors, which is distinguished by its reliability, durability and environmental friendliness. To extend the service life, the wooden leaf should be painted periodically. A wide range of paints and varnishes are used to paint a new wooden door, and you need to be able to work with each properly. Painting a door is a laborious task and it is preceded by careful surface preparation.

Basics of choosing paint materials for wooden interior doors

The paints and varnishes suitable for painting wooden doors are divided into several categories:

• by chemical type - paints, varnishes, dyes, impregnations;
• for the binder component - aqueous and organic;
• by appointment - external, internal, universal;
• by the effect of wood protection - from mechanical stress, chemicals, temperature fluctuations, humidity changes.

Paints are used for open and new doors. Produce transparent and pigmented formulations.The former include a pigment component for the manifestation of the wood structure.

The most popular paint for wooden doors is called alkyd paint. It is inexpensive, provides a very durable coating, and is available in a variety of shades. The only negative point is a specific smell that lasts for several days. Therefore, for painting, either the door is removed from its hinges, taken out into the yard, or the room is left uninhabited until the smell disappears.

A good alternative is acrylic, which does not have a pungent smell. It is also available in many shades, but does not differ in durability. Therefore, to protect the surface, an acrylic varnish should be applied over the acrylic stain.

Lacquer coating provides reliable protection, gives the wooden surface a soft shine. Most often, doors are varnished in rooms with high air humidity, for example, in saunas. What types of varnishes are applicable for painting wood is shown in the table:

Type of varnish	Features
acrylic	available in gloss and matte finish, has no pungent odor, resists fluctuations in humidity and sunlight
oil	the composition is based on glyphthal resins, therefore, the door is thoroughly cleaned before painting, the consistency is dense, so a brush is most suitable for application, there is no specific smell
nitrocellulose	only suitable for painting interior doors, cracks with high humidity, so it is not used for saunas and bathrooms
polyurethane	it is made glossy, semi-matt and matt, adheres perfectly to wood, provides a durable coating, is applicable for painting not only wooden surfaces, but also parquet and veneer
polyester	the composition is durable, but poisonous, smelling strongly, therefore, it is applicable for painting exterior doors exclusively
water-based	properties vary, are determined by chemical composition, there is no specific smell

Stains are intended for tinting a wooden surface, create a protective layer against external negative factors. The protection is short-lived, the coating must be renewed periodically. The types of stains used to paint the doors are shown in the table:

Preparing the canvas for painting

Separate the door from the hinges, lay it on a horizontal surface. If the use of alkyd paint is planned, then it is better to take the door leaf out to the yard. Fix the door so that it is convenient to paint each part. Unscrew the fittings. If it is not removable, wrap it in foil, cover it with tape. It is also necessary to glue the glass of the door panes, if any.

Pre-cleaning

Remove any previous coating from the wood, including putty and primer. Bare wood should remain.It is not difficult to accomplish this stage of work by means of a grinding device, a building hair dryer or a dissolving liquid.

Then sand the wooden surface, smooth out the slightest flaws, degrease. Use a sander and a vacuum cleaner for this. If you don't have a device, you can use medium-grit sandpaper.

Putty and sanding

After finishing sanding, priming the surface, putty visible defects. If the final finish is a varnish, use a compound designed for wood. If the paint is opaque, use any putty.

If the flaws and indentations on the door are significant and the final finish is dark or opaque, use a non-fiberglass automotive sealant.

Allow the putty to dry for the time specified in the instructions. Then sand again. Use medium grit sandpaper first, then finish with fine grit sandpaper.

Antiseptic coating

If the door is in a bathhouse or other room with high humidity, then the wooden surface should be treated before painting with fire retardant and antiseptic. It is recommended to purchase formulations of the same brand, designed to work together for strong interaction with each other, providing quality coverage.

After applying antiseptic protection, prime the door and putty. Treat every inch of the door leaf, including decorative holes and crevices between the jamb and the wall. Once the first putty is dry, apply a second.

The dyeing technology in detail

After processing the door leaf, you can start painting. When carrying out the work, several rules must be taken into account:

• apply the paint in 3 layers;
• put on each new layer after the previous one has dried;
• paint the doors with panels with a brush, immediately removing the excess;
• wooden roller panel doors;
• place the initial layer from the upper left corner to the lower right corner, the second - from top to bottom, the last - from right to left;
• Pull the brush before work, fluff it up so that weakly adhering hairs stick out.

Alkyd enamel

If the door is hinged, paint from top to bottom moving the brush right and left: this way the drops will not run on the painted part of the surface. If the door is removed from its hinges, rests on a horizontal support , then painting can be started from any edge.

But in the process of painting it is impossible to change the direction of movement, otherwise when the paint dries, a melting strip will be noticeable.

Apply the enamel in 2 coats: apply the second after the first has dried. Paint consumption - 50-80 g per 1 m²... The drying time of the paint layer depends on the composition of the components, the ambient temperature and the percentage of humidity. A water-based composition usually dries in half an hour, and the drying of paints based on alkyd resins takes more than a day. If the wooden door is paneled, paint the panels first, then the indentations and protrusions, and finally go over the wooden canvas with a roller.

To create the effect of wenge wood, the wood surface should be painted with a suitable decorative oil-based impregnation. It is supposed to be applied in at least seven layers after applying the main coloring composition.

Stain

So that the wood does not absorb excess moisture and the composition lays flat, the door leaf should be slightly moistened. Apply the stain to the wooden surface first longitudinally to the fibers, then transversely.The finishing coat is also longitudinal.

Cover side surfaces and wooden elements from bottom to top so as not to drip onto unmanaged areas. In this sequence, proceed if the final layer is planned to be an opaque composition. After processing, the wood will absorb moisture, its fibers will swell, so you need to sand it with non-abrasive sandpaper, repeat the steps.

After painting, a dried wooden door looks lighter. Therefore, many coats are needed to achieve the desired shade. If you want to get the job done faster, use an alcohol stain. Then the treated surface does not need to be ground. Although water stains are more popular because they are harmless, they do not emit a pungent odor.

Impregnation

Mix the impregnation well to avoid stains on the coated wooden door. Work with a brush, sponge, spray bottle. Apply the composition to a wooden canvas, spread evenly with a brush, roll out with a roller. Leave to dry for a day, after which apply a second coat.

2. Putty the dry surface, pass an abrasive cloth.Repeat the steps.
3. Dilute paint with solvent to optimum consistency. Apply in 3 coats.
4. Seal the final coat with clear varnish if desired.

diy varnishing

Spray painting is preferred, but can also be painted with a brush. Pour either diluted or heated to 60°C into a spray bottle. Solvent and white spirit solvent essence are suitable for diluting oil varnish. Dissolve other varnishes with construction (646, 647) or automotive thinners (649, 650).

After the first painting with varnish, the wood fibers can rise. Remove them with fine grit sandpaper. Sand carefully to avoid rubbing the protective coating exposing the wood. Wipe the canvas with a soft, clean cloth, cover with a second coat of varnish. Repeat the steps again if necessary. Apply each new coat of varnish when the previous one dries well.

Features of color choice

When choosing a paint for a wooden door, keep in mind that the color should be in harmony with the interior and the color scheme of the room.

Also, when choosing, remember that:

• the room should contain furniture elements of the same shade as the door;
• oil impregnation is optimal for processing interior solid wood elements;
• if the furniture is lacquered, it is better to paint the door in a dark color;
• Door aging effect application is applicable for interiors with antique decor and furniture.

What you need to know about painting an old door

If you plan to paint a wooden door that has served for a long time, you must first remove the previous coating, otherwise the result will not be successful. Use a spatula, with extreme caution so as not to touch the wood, scrape off the paint and putty.

To facilitate the scraping process, you can apply the following methods:

1. Thermal. Involves heating with a blowtorch or hair dryer. Softened paint peels off much faster. Prior to work, plastic fittings and panes must be removed.
2. Chemical. A special organic solvent is applied to the wooden surface with a gun or a roller. The old coating in swells, leaves the tree.

After removing the old layer of paint, wash the door, inspect. Cover the smallest defects with mastic. Dry the canvas, sanding first with medium-grit sandpaper, then with fine-grit sandpaper. Wood primer to improve paint adhesion.
