An important stage in the process of building a wooden house is its insulation. Competently executed, this type of work will provide a comfortable indoor climate and reduce heating costs. As a heater from modern materials, sealant for wood is increasingly used. It is used to fill cracks, crevices and voids in the construction of houses and various repairs. The quality of construction will largely depend on the correct choice of sealant.
First of all, it is taken into account whether it will be used for indoor or outdoor work. You should carefully study the information on the packaging, where the manufacturer indicates the type of material, its properties (water resistance, transparency, elasticity, resistance to high temperatures, etc.).
Wood Sealant Benefits
Of course, natural materials are considered more suitable for their environmental properties, but negative environmental factors often reduce their function to nothing. Sealants are in no way inferior to them, solving quite a variety of tasks in the construction of a wooden house.
A big threat toinsulation is usually represented by birds that pull natural materials from the seams. With the use of sealant, this problem does not arise. The economic benefit is also obvious. The use of sealant allows you to save on the need for re-caulking, the need for which arises as a result of shrinkage of the tree when using natural materials. Provides reliable protection against insects that can cause serious damage to the insulation.
The use of sealant significantly reduces labor costs during work, as it speeds up the process of sealing joints. Reviews confirm that repair costs are reduced, because it is not necessary to remove the old material completely, it is enough just to apply a new layer of the composition to the damaged area.
Acrylic Sealant
This is the most affordable and easiest wood sealer. To work with it, no additional materials in the form of solvents and oxidizing agents are required. The composition is simply applied to the seams. Preference should be given to waterproof sealant, which is environmentally friendly, resistant to high and low temperatures, has excellent adhesion to the surface. Customer reviews say that it is quite easy to choose a material that matches the color. The disadvantage of acrylic sealant is only instability to deformation loads. Its demand in the building materials market is explained by its low price, which averages from 100 to 130 rubles, and its long service life - this wood sealant can last up to 25 years.
Silicone Sealants
Potheir qualities are somewhat superior to acrylic. Due to the presence of silicone in the composition, these sealants are more durable, elastic, able to withstand temperature extremes, resistant to deformation. Therefore, they are great for outdoor use.
After drying, the wood joint sealant can be painted over with oil paint. A 300 ml bottle can be purchased for 160 rubles or more, depending on the manufacturer.
Polyurethane sealants
They are mainly used for sealing roofs, foundations, and for repairing complex structures. This material is highly durable and has a long service life. According to reviews, it is elastic, resistant to water, temperature extremes, tolerates deformation and interacts with any surface.
Polyurethane wood sealant is used when ease of use, ease of use and durability are required. It costs about the same as silicone - from 150 rubles.
Bitumen sealants
The simplest type of sealant, which is based on bitumen and rubber. For roofing work, it is most relevant. Due to its composition, the sealant does not dissolve in water, therefore it has a high level of strength and resistance to rain and moisture. Very easy to use, it allows you to quickly cope with the sealing of cracks and seams. Of the shortcomings, one can only single out that it is not suitable for painting, and at temperatures below 0 ° C it is not recommended to usebituminous sealant for wood. The price of a package of 300 ml is 180-190 rubles.
The presence of hydrocarbon solvents in the sealant requires precautions. If work is carried out indoors, ventilation must be ensured. Avoid contact with the skin or eyes, be sure to use gloves, a respirator and special clothing to protect.
In order to eliminate cracks, increase the heat-saving properties of the house, and a wood sealant is intended. Reviews posted on this topic present it as the most advantageous material for sealing interventional joints, and thousands of homes built using this technology confirm the effectiveness of sealants.
