Sealants

Areas of application of the sealant

These means used for sealing seams, joints, cracks and crevices in building structures. They create a waterproof barrier and reduce heat loss. In technical systems, these tools prevent the penetration of air, dust, and moisture and provide a balance of deformations between different materials.

Features and rules for the use of sealants

Before application, the surface should be cleaned of dust and moisture. The depth of the seam must comply with the standards. Apply in an even layer, use a seam cord to control thickness. After application, smooth the surface with a tool or water to ensure contact with both sides of the seam. It is important to wait for complete drying, which guarantees the strength and elasticity of the connection.

Types of sealants - comparison of basic characteristics

The assortment includes acrylic, polyurethane, silicone, as well as agents adapted to specific conditions — for seams with increased load, chemical resistance or fire resistance.
Acrylic sealants suitable for interior work and easily painted.  Polyurethane are characterized by high resistance to mechanical influences and temperature fluctuations. Silicone resistant to water, ultraviolet and aggressive environments. Special formulas are adapted for use in contact with oil, hot air or sea water.
