Varnishing of wooden doors. Review of materials. Work technology

Varnishing wooden doors is an effective, simple and budget-friendly way to update worn-out solid wood panels. If they are outdated and the appearance leaves much to be desired, this is not yet a reason to purchase and install new ones. Sometimes it’s enough just to coat the doors with varnish. Moreover, it is wooden products that are often of artistic value, and their restoration turns out to be preferable to replacing them with modern analogues.

Let's talk about how to varnish wooden doors. Unlike tinting impregnations, this material creates a film of varying degrees of gloss on the surface of the wood - matte, semi-matte, semi-gloss or glossy. The Russian market offers varnishes based on alkyd, polyurethane and acrylic, as well as nitro compounds. Materials based on alkyd resins and polyurethane binders are characterized by a strong odor and short polymerization time. Nitrovarnishes are leaders in both the amount of VOCs and drying speed. Acrylic materials are pleasant to work with, have a low odor, and dry on average in 4 hours. It is the last group of varnishes that is the largest, most diverse and popular among buyers. It is worth noting that it is recommended to varnish interior doors twice, or even three times, with intermediate sanding of the rising pile.

How to prepare a door leaf for varnishing

To properly varnish a door, you must properly prepare the surface. If you are going to varnish a new product, you need to clean the base from dirt and dust. It is advisable to slightly moisten the surface with a spray bottle to allow the pile to rise for sanding. After sanding, remove dust with a soft cloth or vacuum cleaner. If the door was previously painted, it is advisable to remove the old coating with sanding paper or a sponge before varnishing.

If there are noticeable cracks or chips on the surface, they will have to be repaired with wood putty. This will increase the duration of the work (you will need to wait until the material has completely dried, then sand the repaired area), but will allow the restoration to be completed efficiently. We recommend wood putties such as Tex pro universal.

Modern materials, as a rule, do not smudge when applied, lie flat on the surface and do not spread unless you apply an excessive amount of varnish to the brush. Therefore, painting with varnish with your own hands can be done directly in a vertical position. However, in accordance with traditional technology, it is advisable to remove the door leaf from the hinges. Masters believe that varnishing correctly means bringing the canvas into a horizontal position.

Detailed information on how to properly varnish wood can be found in the technical documentation included with the product.

How to varnish a door

Using Tikkurila Kiva 30 as an example, we’ll look at how to varnish doors at home. Before starting painting work, the varnish must be thoroughly mixed and this procedure must be repeated periodically to avoid the formation of sediment. Working tools for coating doors with varnish can be a brush, a sponge, or a Tikkurila applicator. You can also apply the varnish by spraying. If you plan to work with tinted varnish, keep in mind that the final color of the door leaf will depend on the type of wood and the number of layers applied (usually 2 approaches, but 3 layers can be applied). To avoid differences in shades, varnishing wood on one piece should be done in one approach.

Conclusion

If you want to tidy up the interior wooden doors in your country house or apartment and update their appearance, then you can complete all stages of the work with your own hands and without the use of grinding machines or construction hair dryers. It is important to choose a suitable material, decide on its shade, take into account that when working with some compositions (nitro varnishes, alkyd enamels) there will be a strong odor, and high-quality ventilation of the room or transportation of the paintings to another (non-residential) place will be required. In general, any solid wood canvas can be put in order. Proper varnishing of old doors will prolong their life and make them an interior decoration. The exception is canvases that have lost their structural strength or have been subjected to severe biological damage.

Using wood stain

The wood surface should be painted with stain in the same way as with regular paint. The only thing is that this impregnation dries very quickly, so you should work just as quickly, but carefully .

Before completing the work, you must not allow the stain layer to dry, otherwise a seam in this place will be clearly visible, different from the rest of the surface. That is why you should not put a lot of solution on the brush.

To paint a wooden surface with stain, use:

• Paint brush.
• Foam roller.
• Automatic or manual sprayer.

The stain is applied parallel to the direction of the wood grain and therefore should not be applied to another section unless the first is finished. In the place where the two sections are connected, it is necessary to ensure that the applied layers of impregnation do not overlap each other.

Thanks to stain, wood acquires a refined and excellent color . In addition, it protects and enhances the wood grain. After the planed plank floor is laid, it is necessary that it is always clean, otherwise, after applying the stain, all the stains will begin to stand out.

If there are greasy stains on the floor, the stain in this area may not be absorbed into the wood. If the wooden parquet is in good condition and there is no need to restore or putty it, then covering it with such impregnation is an excellent solution to renew the old parquet.

If you need to get a new shade, you can mix several stain colors. You need to stir carefully so that splashes do not fall on the floor, as such stains will subsequently stand out very strongly. It is recommended to mix only compatible components.

What to consider when choosing paint?

Having decided to independently restore interior wooden doors, you need to learn an important rule: odorless paint is intended for interior work, and all other enamels and varnishes are for external use.

When choosing enamel for windows and doors, take into account the characteristics of the canvas:

• The door block is made from different types of wood and waste from the woodworking industry. The density of the material determines the amount of paint absorption before it dries. An extra layer is an additional cost. When choosing an expensive paint and varnish material, it is wise to use drying oil. After impregnation, loose wood will be covered with a film, and paint absorption will decrease.
• The consumption of varnish or enamel for doors depends on the surface. For a smooth one, just apply two thin coats of paint. Rough material requires more layers.
• When restoring door blocks, it will not be possible to completely remove the previous coating. The new paint and varnish material should not contain aggressive substances that corrode the old paint. During the reaction, swelling and peeling will appear on the canvas.

Additionally, when choosing a paint and varnish material, the intensity of use of the door block, as well as the level of humidity and ambient temperature

The choice of color is a personal preference. The new canvas looks beautiful under clear varnish or with the addition of stain. After cleaning, it is better to cover the old door with enamel, choosing the desired color.

Frequent changes to the interior are not complete without repainting the door block. To avoid future difficulties, choose a paint material that is easily removed from the surface.

Painting pine canvas

The advantage of inexpensive pine is the pleasant smell of pine needles, which brings peace to the house and promotes good sleep. Pine is classified as a wood that is susceptible to environmental influences. Pine will become durable and wear-resistant if it is painted with the chosen paint coating.

Not all interior designers are willing to use pine doors - they have a lot of knots. This deficiency can be corrected with the help of stain, giving a noble shade.

Before painting a pine door, it is puttied and sanded. Resin stains are removed, the pine door leaf is sanded. To paint pine doors you need to do the following:

• Any pine door is pre-treated with sandpaper - sanded.
• The surface of the pine canvas is cleaned of dust.
• Pine doors are primed, which promotes uniform application of paint and protects the wood from rotting. To improve antiseptic protection, special impregnation is used.
• Next, a layer of stain of the required shade is applied to the pine door using a roller. Opaque paints are suitable for completely coloring the texture.
• The pine door is varnished.

When coating solid wood doors with paint and varnish, do not save time and do not shorten work processes. This results in an unattractive appearance and the appearance of defects on the surface of the canvas. Therefore, carrying out the main stages of painting from stripping to polishing is an important aspect of it.

Why apply stain to wood?

To better protect the wood flooring and extend its service life, it is recommended to treat it with stain. This impregnation penetrates deeply into the pores of the wood and enters into a chemical reaction with tannins located in the growth rings, giving the wood a light- and water-resistant color.

In addition, stain protects the wood from borers, mold fungi and other infections and pests. Modern liquid stains come in the following types:

• oil;
• alcohol;
• aquatic.

Let us consider their characteristic properties in more detail.

Water stain

This impregnation comes in two types: in the form of ready-made solutions that can be used immediately, and in powder form. A solution should be prepared from it. Water stain does not require drying oil , white spirit and other solvents.

However, it has one significant drawback: when the impregnation penetrates into the wood, it lifts its fibers , leaving the wood unprotected from excess moisture.

But, on the other hand, with the help of such wood processing, its structure is emphasized and highlighted. Therefore, today this type of stain is considered the most common.

Alcohol stain

This impregnation is a solution of aniline dye in ethyl alcohol. It is used for decorative and antiseptic painting of wood products. With the help of alcohol stain, pile lifting is reduced and wood swelling does not occur.

Using this type of stain, it is quite difficult to achieve uniform coloring, because the composition dries very quickly and stains can form . This impregnation is best suited for tinting small products, but it will not be suitable for painting parquet.

Oil stain

This impregnation is a dye dissolved in flax oil. It is the most convenient to work with and can be applied in different ways. Oil stain does not lift fibers and is evenly distributed over the entire wooden surface. Products processed in this way can always be easily repainted and restored .
