An important step in the construction process of a wooden house is its insulation. Properly executed, this type of work will provide a comfortable indoor climate and reduce heating costs. As a heater from modern materials, wood sealant is increasingly being 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 internal or external works. Carefully study the information on the package, where the manufacturer indicates the type of material, its properties (water resistance, transparency, elasticity, resistance to high temperatures, etc.).
Sealant for wood: 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 large threat to the insulation is usually posed by birds that take away natural materials from the seams. Using sealant this problem does not occur. Obvious and economic benefits. The use of sealant allows you to save on the need for repeated caulking, the need for which arises as a result of tree shrinkage 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, because it speeds up the process of sealing joints. The reviews confirm that the cost of repair work is reduced, because it is not necessary to completely remove the old material, just apply a new layer of the composition to the damaged area.
Acrylic Sealant
This is the most affordable and simple sealant for wood. To work with it does not require additional materials in the form of solvents and oxidizing agents. 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’s quite easy to choose the right color. The disadvantage of acrylic sealant is only instability to deformation loads. Its relevance in the building materials market is explained by its low price, which averages from 100 to 130 rubles, and its long service life - up to 25 years, this sealant for wood can last.
Silicone sealants
By their qualities, they are somewhat superior to acrylic. Due to the presence of silicone, these sealants are more durable, flexible, able to withstand temperature extremes, and are resistant to deformation. Therefore, they are great for outdoor use.
After drying, the joint sealant for wood can be painted with oil paint. A capacity of 300 ml can be purchased for 160 rubles and above, depending on the manufacturer.
Polyurethane Sealants
They are mainly used for sealing roofs, foundations, and for repairing complex structures. This material is characterized by high strength and long service life. According to reviews, it is flexible, resistant to water, temperature changes, tolerates deformation and interacts with any surfaces.
Polyurethane sealant for wood 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, 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 repair of cracks and seams. Among the shortcomings, one can single out only that it is not suitable for painting, and at a temperature below 0 ° C it is not recommended to use bitumen sealant for wood. The price of a package of 300 ml is 180-190 rubles.
The presence of hydrocarbon solvents in the sealant requires precaution. If work is carried out indoors, it is necessary to provide ventilation. Avoid contact with 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 sealant for wood is intended. The reviews posted on this topic present it as the most winning material when sealing inter-crown seams, and thousands of houses built using this technology confirm the effectiveness of the use of sealants.
