Natural wood is in great demand in the construction field. This material has a lot of positive qualities and a number of advantages. Thanks to modern technology, there are many ways to treat wood to improve its performance. Impregnation is one of the important processes for the future product to acquire the required qualities. Such wood is used for various purposes, which you can learn more about later.

What it is?

Impregnation is the process of impregnating wood with special compounds that are designed to protect the material from mold, rotting and various insects. This method allows you to extend the life of the product from the boards, which will remain presentable for many years. Despite the fact that the wood can be well dried, one cannot be completely sure that there is no harmful fungus left inside.

Therefore, we can say with confidence that impregnation is a special treatment method, by means of which all the residue that negatively affects the structure of the tree is destroyed. Thanks to this process, it is possible to extend the service life of terrace timber even up to 60 years.

However, it should be noted that the procedure does not protect against mechanical damage.

Many furniture manufacturers use paints and varnishes that are designed to preserve the appearance of the structure . However, such a layer wears off over time, so it needs to be updated. As for impregnation, it reaches a greater depth of the structure of the material, therefore, the degree of protection is improved several times. The main advantages of the procedure include the fact that during it safe formulations are used that do not harm the health of living beings and the environment.

During operation, wood does not emit toxins, which is also a big plus. The impregnated board is offered at an affordable price, unlike other analogs made of composite or larch.

It should be noted that after one impregnation process, the material does not require re-impregnation, processing is enough for the entire life of the product.

Impregnation methods

Impregnates are divided into several types, each of which has its own characteristics. Weather protection impregnations strengthen the wood and improve its resistance to seasonal climatic changes, weather conditions, ultraviolet light and prolonged heating. Many antiseptic formulations are designed to suppress parasitic microflora . They contain biocides that prevent bacteria and fungus from growing. These formulations are suitable for the treatment of floor beams, sheathing boards and purlins.

There are fire retardants on the market, the main feature of which is fire resistance . Wood is easily flammable, so just such a substance should be used to protect against fire - it will reduce the risks, and often completely eliminate the possibility of flammability. Many manufacturers use combination formulations that are in high demand. They are able to penetrate deep into the wood structure, creating a protective hydrophobic film, so the material will not be afraid of high humidity. There are two impregnation options.

Deep

This method is in the greatest demand, since thanks to it, wood is processed from almost all sides. However, deep impregnation can also be carried out in different ways . The dive can be done even at home without any special knowledge or experience. To do this, you will need a container with the drug. The wood will quickly penetrate the composition, the degree of impregnation directly depends on the time during which the board remains in the tank. If deep impregnation is required, a week will be enough to get the desired result.

The second method is pressure impregnation . This procedure requires special equipment. The composition will penetrate deeply and quickly into the wood, therefore, a 30% moisture content of the sawn timber is allowed. Diffusion impregnation is also quite effective, but it is not used as often as the previous options. The main task is to pour the mixture of sand and preparation in the correct proportion, cover the stacks and then wrap the wood in foil. This impregnation will last for about 10 days.

It should be noted that this method requires serious investments in finished products and takes a lot of time.

Surface

Such impregnation is the simplest, but not as effective as deep impregnation. Despite this, the method is used quite often if the product needs to be covered with a protective layer only on top. For this, rollers or brushes are used to paint horizontally laid wood. The maximum depth of impregnation with the solution reaches 5 mm, and in order to achieve the best effect, it is recommended to carry out the procedure several times.

If the boards have a lot of burrs, and the surface is not processed, therefore it is rough, the impregnation must be rubbed in, since the staining will be difficult . Tight swabs are dipped in a solution that is rubbed into the wood. In some cases, a spray can be used - this method is suitable for covering facades and floors. Penetration will be shallow, but it can work in hard-to-reach areas.

Varieties

Impregnated conifers are in great demand, but pine, spruce and other types of wood can be impregnated. Most often, it is the conifers that are used, since they are often used in the construction of saunas and baths, as well as various furniture products that can be exposed to moisture and adverse weather conditions. Larch boards have the property of resisting the decay process, however, if it is required to enhance the natural characteristics, impregnation can be made . In addition, some of the wood may remain unprotected, so it is better to carry out an impregnation procedure, which will extend the life of the material.

Larch lumber is often used for fencing, and you can also make decking or deck planks to put under the roof . It is a massive material without reliefs with rounded edges. The product will be exposed to temperature extremes, frost and bad weather conditions, so it needs to be processed to prolong its life. As for the size of the board, it all depends on the scope of its application, in addition, manufacturers often offer different options, for example, 50x200x6000, 20x95x6000 and 50x150x6000 mm.

Applications

Lumber impregnated with an antiseptic is widely used not only in everyday life, but also in industry. For example, wooden poles are installed as support structures for power lines. Thanks to the composition, a long service life is ensured, moreover, the posts are protected from biological pests. Impregnated materials are often used in the production of sleepers. To increase the efficiency of the impregnation, the workpieces are pricked and impregnated in an autoclave.

Over the past decade, the timber construction industry has become very popular, which has led to an increased demand for impregnated lumber. Fences are erected from such wood, terraces are made, piers and gazebos are erected, children's playgrounds are equipped. And also this material is ideal for interior and exterior cladding of premises.

When it comes to decking, it is intended for laying the flooring in open areas such as verandas. The board is able to cope with heavy loads, therefore it is suitable as a flooring on sites and in garages. The material is often used to make beautiful garden furniture.

Thus, it is safe to say that impregnated wood is in great demand in various fields due to its performance and quality characteristics.

In addition, on the market you can find materials of all sizes and thicknesses, choosing what suits your personal requirements.

Can you paint?

After using the impregnation, the wood can take on a thick green tint, which resembles a marsh color, and in the area of knots there will be a bluish tint. A few weeks after the procedure, ultraviolet light will begin to act on the material, so the intensity will drop slightly, and the green color will acquire a pleasant yellow tint. Many people wonder if such consequences can be prevented by staining . The answer will be yes, but the proportions must be correct in order to get the desired color.

During the preparation of the impregnating composition, color can be added, then the material will turn brown . As for the impact on performance, they will not be compromised, moreover, the wood will look much more expensive and luxurious.

But it should be understood that the sun's rays and atmospheric changes have an effect, so the color will eventually change to a gray tint. To avoid such a nuisance, experts recommend protecting the impregnated wood with a glaze coating and oils that have a UV filter effect.

You should not rush to paint the impregnated product, you can wait for it to burn out in the sun, because the green color will soon turn into a beautiful honey shade that you may like . For working with green and brown decking boards, it is better to use special protective oils, to which a colorant is added. As you can see, the properties of wood can be improved at times even at home, if the material is impregnated with a special compound.
