Heat-resistant sealant - a unique means of insulation

Today, in the construction of fireplaces and stoves, heat-resistant adhesive sealant is often used . Its purpose is to seal spaces and cracks in the walls of chimneys and pipes. In addition, this material is often used in the installation of underfloor heating and in other electrical construction works.

How has heat-resistant sealant gained popularity?

Often it is used to insulate joints and seams. It fills the space well, dries quickly and hardens, protects the surface well. Sealants vary in composition and properties, since for different surfaces and areas an individual selection of the specified substance is required. For example, moisture-resistant material is suitable for the bathroom and is completely unsuitable for fireplaces and stoves. It requires a heat-resistant sealant that can withstand high temperatures. In addition to these properties, it must have an environmentally and biologically safe composition. Otherwise, harmful substances will get into the air and will have an adverse effect on health.

The most common silicone sealant is heat-resistant for stoves and fireplaces. Polysulfide and urethate heat-resistant materials that can withstand up to 1500 ° C are also popular. Due to their elasticity and fluidity, they penetrate deep into the space and effectively fill it. In addition to sealing fireplaces, chimneys and stoves, heat-resistant material is used when laying tiles to fireplaces and stoves.

Heat-resistant sealant has the following basic properties:

  1. Protects equipment and devices from moisture and chemical components.
  2. It has a wide color gamut, which makes it possible to choose the desired shade for absolutely any surface.
  3. It creates excellent adhesion to materials: metal, brick, concrete, tile.
  4. It is fireproof. Enhances fire protection.
  5. It has a high drying rate of 2 mm per day.

Scope of application

Heat-resistant sealant is used not only in the construction of furnaces, but also in the arrangement of floors, ventilation, fire doors. Do not take cheap materials. They are often of poor quality and contain harmful components, while each reputable and self-respecting company will produce only high-quality products that are not harmful to health.

How to apply heat-resistant sealant?

1. First, the surface is cleaned with solvents or acetone from bitumen, dirt, grease.

2. Protect masking tape from new contaminants.

3. The tip of the nozzle of the cartridge is cut off at an angle and closed with a special cap.

4. Apply this material under pressure for better adhesion.

Heat-resistant sealant requires work at a temperature not lower than + 5 ° C. When using it, the use of work clothing is mandatory. Compliance with safety regulations and strict implementation of the instructions gives the most successful and high-quality results.
