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 other electrical construction work.
What made heat-resistant sealant popular?
Often it is used to isolate joints and seams. It fills the space well, dries and hardens quickly, protects the surface well. Sealants differ in composition and properties, since individual selection of the specified substance is required for different surfaces and areas. For example, moisture-resistant material is suitable for a bathroom and is completely unsuitable for fireplaces and stoves. This requires a heat-resistant sealant that can resist high temperatures. In addition to these properties, it must have an environmentally and biologically safe composition. Otherwise, harmful substances will get intoair and will have adverse he alth effects.
The most common heat-resistant silicone sealant for stoves and fireplaces. Also popular are polysulfide and urethate heat-resistant materials that can withstand up to 1500 ° C. 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 for fireplaces and stoves.
Heat-resistant sealant has the following main properties:
- Protects equipment and appliances from moisture and chemical components.
- It has a wide range of colors, which makes it possible to choose the desired shade for absolutely any surface.
- Creates excellent adhesion to materials: metal, brick, concrete, tile.
- Is fireproof. Enhances fire protection.
- Has a high drying rate - 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 every reputable and self-respecting company will produce only high-quality products that are not harmful to he alth.
How to apply heat resistant sealant?
1. First, the surface is cleaned with solvents or acetone from bitumen, dirt, grease.
2. Protect with masking tape from new contamination.
3. The tip of the cartridge spout is cut off at an angle and closed with a special cap.
4. This material is applied under pressure for better adhesion.
Heat-resistant sealant requires work at a temperature not lower than +5°C. When using it, the use of protective clothing is mandatory. Compliance with safety precautions and strict implementation of the instructions gives the most successful and high-quality results.
