Overview of tools to protect wood from moisture, fire, insects and rot

Wood is a soft, but durable, beloved by many material for the construction of houses in summer cottages. Even if the building is built of brick or foam blocks, logs, timber or planks are used to build a bathhouse, garage, gazebo, veranda. Not without wooden decor - a well, benches, swings, bridges. Fences and fences are also made of wood. To avoid the rapid destruction of the material, it is necessary to effectively protect the wood from external factors: excessive moisture, fire, insect pests.

How to protect wood from moisture?

If the moisture content of the material exceeds 15%, the structure of the wood begins to collapse: swell, delaminate, and then dry out. As a result, the products change their shape, cracks and gaps appear. Almost all wood elements are affected by high humidity, except, perhaps, sisal and rattan, since they come from the tropics.

An experiment showed that water does not penetrate into the pores of a bar treated with a water-repellent composition, while it is quickly absorbed into unprotected wood

There are special solutions that protect wood from moisture. They are divided into two groups:

  • penetrating;
  • film-forming.

The first group provides a more reliable barrier against liquid penetration into the tree structure. The processing of the compositions of the second group should be repeated over time. Consider two remedies that resist high humidity.

Aidol Langzeit-Lasur belongs to the impregnating medium-viscous compositions, excellent for covering the walls of the house, country furniture, balcony and terrace railings, hedges. Azure is so safe that it can cover children's toys and buildings. It has many decorative shades: silver gray, teak, ebony, dark oak.

If coniferous wood is treated with Aidol Langzeit-Lasur, it should first be primed. This rule also applies to products damaged by fungus or mold.

Belinka Interier Sauna incorporates acrylic resins, water and additives. This is a colorless azure, ideal for processing wood in baths or saunas. Two layers of the solution are applied by roller, brush or spray.

Belinka Interier Sauna does not mask the natural texture of the tree, but only makes it more silky and shiny. A can of 2.5 l azure costs 950-1000 rubles

Methods of protection against decay

Temperature changes, precipitation, solar radiation lead to untimely rotting of wood. The first signs of decay are the appearance of mold and fungus. Large foci indicate that the material can no longer be saved. If wooden products or buildings are experiencing atmospheric turmoil, high humidity from precipitation and condensation, it will not be superfluous to carry out preventive work that will protect the wood from decay.

The best helpers in this matter are antiseptics, which are pastes or liquid solutions. Some of them are universal, that is, they protect the material not only from moldy fungi, but also from beetles. Examples of such formulations are two popular remedies.

PINOTEX IMPRA is used for processing wooden surfaces that are not subject to further decoration. Usually these are beams, roof slings, lathing details, that is, hidden parts of buildings. The impregnation is green. On the wood covered by it, the appearance of mold, blue, fungus and rot is excluded.

The antiseptic Pinotex Impra goes on sale in large containers. The price of the product: 3 l - 1100 rubles, 10 l - 3350 rubles

Senezh Ecobio is used both as an independent coating, and as a primer for varnish or paint. 2-3 layers of the product protect the wood from rotting for 30 years.

If the wooden surface was originally treated with varnish, paint, drying oil or other water-repellent agents, use SENEG ECOBIO to no avail.

Fire retardants - reliable fire protection

To protect wood from fire, there are fire-resistant solutions - flame retardants. For residential buildings, they are mandatory. Under the influence of a flame, the substance with which the wood is impregnated turns into a thin film that can interfere with the flame for a while. Coatings have a different look:

  • solutions;
  • plasters;
  • paints;
  • plastering.

Fire retardant sample - NEOMID 530, impregnation for exterior and interior use. Guaranteed service life - 7 years. Reliably protects wooden walls, ceilings, door and window blocks, partitions from fire. The composition of the flame retardant does not change the structure of the wood. On top of the fire retardant solution, varnishes, paints, primers can be applied.

Please note that when applying NEOMID 530 flame retardant, light tinting of the material, depending on the type of wood, is therefore recommended before testing

Pyrilax is a bio-pyrene that provides protection of wood from fire and localizes fires. The prefix bio- means that the product is simultaneously a barrier to the appearance of mold and insects. The solution provides effective protection inside and outside the building, is safe for processing buildings for poultry and livestock.

Pirilax for external use is not washed out by precipitation for 13-15 years. Indoors, it provides protection for 25 years

Insects - no chance!

Tiny beetles can dust wooden furniture, walls and floors of a house. Beetle grinders, barbel and weevils, together with their larvae, slowly but surely destroy unprocessed building material. Only protecting wood from harmful insects will save the situation.

It is much easier and cheaper to take preventative measures than replacing damaged logs and beams. Insecticidal solutions will expel already established pests from the shelters and block the path for beginners. You can use folk remedies - a solution of tar in turpentine, chlorophos, paraffin or a mixture of kerosene and carbolic. But more effective formulations for professional processing.

Aqua-varnish Bor impregnates the surface of the wood, protecting it from any negative manifestations from the outside, including beetles. They are covered with window and door blocks, baseboards, stairs, railings, fences, wooden walls of houses. Transparent impregnation does not distort the texture of wood, it only changes its color to the desired one. Varnish can be diluted with water, but its percentage should not exceed 10%.

The number of layers of applied Aqua-varnish depends on the location of the wooden elements: two are enough indoors, at least three outside;

The antiseptic Tonotex serves both to protect wooden surfaces and to decorate. Its composition emphasizes the texture of the tree without changing its properties. Gamma of various shades allows you to give ordinary wood the color of one of the valuable species of wood.

Tonotex refers to universal compounds that are used for processing wood on the territory of a summer cottage: it will protect both from atmospheric troubles and from biological threats

Comprehensive protection for residential buildings

If you compare a village house, built in the middle of the last century, and a modern summer cottage, you can see a big difference. It refers to the appearance of wood. Old houses had virtually no additional protection, so after a few years the logs became porous, gray, covered with cracks and small holes. Now, thanks to the complex processing of all wooden parts and structures, the appearance of houses does not change with time.

Construction supermarkets offer a wide range of protective compounds for wood: both affordable domestic and more expensive foreign production

Various impregnations, solutions, azure, varnishes and paints have in their composition substances that protect wood from insects, rapid wear and decay. Using protective compounds in the construction of a house, you can make it really impregnable, reliable and safe.
