tiivistyslaastin

Tiivistyslaasti, sometimes referred to as sealing mortar or jointing compound, is a specialized building material used primarily for sealing gaps and joints in construction. Its main purpose is to prevent the ingress of water, air, and other environmental elements, thereby enhancing the energy efficiency and durability of structures. It is often employed in areas where airtightness and watertightness are critical, such as around windows, doors, pipe penetrations, and expansion joints.

The composition of tiivistyslaasti can vary, but it typically includes a binder such as cement or gypsum, aggregates like sand, and various additives. These additives can impart specific properties like flexibility, adhesion, and resistance to weathering. The material is usually applied in a semi-liquid or paste form, allowing it to fill irregular spaces effectively. Once cured, it forms a solid, durable seal.

The application process typically involves preparing the joint or gap by cleaning it thoroughly. The tiivistyslaasti is then applied using tools such as trowels, spatulas, or specialized caulking guns. The consistency and curing time depend on the specific product formulation and environmental conditions. Proper application is essential to achieve the desired sealing performance and longevity. Tiivistyslaasti is a cost-effective solution for improving building envelope performance and preventing moisture-related damage.
