What and how to paint the timber inside the house?

The popularity of timber houses has long been a relatively stable phenomenon. This is not surprising, because such buildings are environmentally friendly, beauty, convenience and comfort. And in them, as in any others, it is often required to carry out finishing work after construction..

One of the easiest will be to paint the timber inside the timber-type house.. This option is considered the most budgetary. Let’s try to figure out what it is for, how to prepare the surface of the walls for painting, and what types of paints and varnishes can be used for this.

Why do you need painting?

If we talk about why, in general, we need an internal treatment of walls with paint or any paints and varnishes, then we need to remember that wood itself is a rather soft natural material. It is extremely vulnerable and does not resist dampness, humidity, mold and mildew, and can simply dry out.. And it is painting the walls of a wooden house that can solve these problems..

For example, if this is done in the bathroom, then the walls will be protected from the effects of increased moisture on the wood, which is why fungus and mold will simply not appear on them. In addition, if you want to make some interesting and unusual interior in the house, and there are not so many funds, then applying paint on the walls will be the most budget option..

At the same time, you can realize any fantasy, which will allow you to create something amazing and unusual, and not spend much money.

How to prepare the walls?

It should be said that it is impossible to simply apply paint to the wall from a profiled or other type of timber. Before this, preparatory work is required, which will prepare the walls for the application of paints and varnishes.. As a rule, wall preparation work is divided into 3 stages:

  • stripping;
  • grinding;
  • protective treatment.

It will not be superfluous to say a few words about the solutions with which the tree is covered before the application of paints and varnishes. They are intended to protect the wood structure from natural factors – high humidity and exposure to direct sunlight, as well as from damage by various insects, as well as fungus and mold. Usually such substances are made on the basis of antiseptics, although there are also fire retardants..

They are also applied to wood from the inside of the room in order to significantly reduce the risk of wood fire in case of fire hazardous situations..

Here it is required to say what, in general, there are compositions for wood processing, and why they are needed.

  • Different primer options. Their use allows you to create a special protective layer and increase the adhesion of paint to the surface. And it is much easier to paint the primed surface..
  • Stains. They give the material different shades and reduce the negative impact of various external factors..
  • Antiseptics, which protect wood from mold and mildew.
  • Paints that form a durable layer on the surface. Due to the large number of types and shades, it becomes possible to paint the walls in the color of interest to the owner of the house and create the required interior.
  • Lucky. These are colorless or slightly tinged substances that give wood protection and shine, improve its appearance and increase its durability..

If desired, the above formulations can be combined.

When buying any protective solution, you should pay attention to the label on the package. The area of ​​its use must be indicated there. That is, the composition can be used for only internal or exclusively for external work.. Consider the algorithm for preparing the walls.

  • We check the wall for the presence of darkened logs and boards. If they are, then they should be preliminarily clarified with the help of special compositions or whiteness. If damaged parts are found during the inspection, they must be replaced with new ones..
  • Now you need to clean the wood and then sand it. It is best to remove loose fibers using a wire brush..
  • We apply a primer to the wall, which will make it possible to then apply the paint more evenly and will not allow it to be absorbed too deep.
  • If there is old paintwork, it must be removed by scraping or rinsing off. It is possible to apply paint over the old one only if they have the same composition..

What can be painted?

If we talk about what can be used to paint the timber, then these are paints or varnishes. They are used most often. For interior work, several types of varnishes are used..

  • Acrylic. Its main advantage is the lack of smell. For this reason, the inner part of the wall of the timber and partitions is covered with it. But it also has a serious disadvantage, because such a coating is very short-lived..
  • Alkyd. Contains pentaphthalic and glyphthalic resins in combination with various solvent oils.
  • Alcoholic. The use of such a composition allows a pleasant glossy surface to be obtained. But it should not be used in rooms with high humidity, because it does not protect the wood from moisture..
  • Oil. This varnish is usually made on the basis of synthetic or natural resin. It is usually used indoors as it penetrates deeply into wood and forms a protective layer on the surface..
  • Polyurethane. Differs in strength and durability.
  • Nitrocellulose. Often used for laminated veneer lumber, allows you to preserve its color and texture.

There are several types of paint for timber.

  • Water-based. Dries very quickly and is odorless.
  • Acrylic. Such a coating retains its original appearance for a long time..
  • Oil. The coating made with it has excellent resistance to mechanical stress and water. But this paint dries for a very long time after application. And from time to time such a surface must be tinted..
  • Wax. Has excellent water repellency.
  • Silicone. Creates a high-quality and durable coating. At the same time, it allows the wood to breathe and makes it more resistant to mechanical damage.
  • Silicate. Forms a moisture-resistant coating, ideal for bathrooms and saunas.
  • Alkyd. Not a bad solution for indoor use. Sometimes it is also used for external processing, but then it quickly fades under the influence of direct sunlight..


The first thing to say is that you should not neglect the high-quality pre-treatment of the wall before painting.. This happens quite often, and then the owners of the house are forced to redo everything, wasting time and money.. And you should also select paints and varnishes that are as harmless to human health as possible. This will be especially important for interior finishing work..

Another tip – before buying, you should carefully study the information on the packaging of the material in order to clearly understand its properties and characteristics..
