Heat-Resistant Sealant for Stoves and Fireplaces
KSK-70X
High-quality, heat-resistant silicate sealant for sealing joints and filling cracks during the installation and repair of fireplaces, stoves, ovens, heating systems, pipes and chimneys where high temperature resistance is required.
Recommended for indoor and outdoor use. The product has excellent adhesion to concrete, fire bricks, stone, glass, cast iron and steel. Pre-priming is not required.
Forms strong, durable joints that resist fading, UV radiation, weathering and temperature changes. Thixotropic: does not run or sag in the joint. The cured sealant is not elastic and is therefore unsuitable for expansion joints. Designed for joints subject to limited vibration and movement at high temperatures. Helps prevent the spread of fire, smoke and gases. Odorless and asbestos-free.

Application
- It’s recommended to apply the product at an ambient temperature from +5°C to +35°C. The temperature of the sealant should be +20°C… +25°C.
- Apply the sealant to clean, degreased surfaces. Before applying, get the surfaces wet with water.
- Protect adjacent surfaces with masking tape for a neat finish.
- Cut off the cartridge tip above the thread and screw on the nozzle. Remove the nozzle cap and cut the nozzle at a 45° angle to match the joint width.
- Apply with a cartridge caulking gun.
- Apply the sealant to the entire depth of the joint and smooth out the surface immediately after application with a wet putty knife.
- The mixture will be cured within a day, and during this time it can be slightly heated.
- After curing, small cracks might appear in the surface, due to setting shrinkage. In this case, an additional sealant coat should be applied.
- Tools and surfaces should be washed well with water before curing, otherwise it is difficult to clean them after the sealant has cured.
Note! Do not apply the sealant at ambient temperatures below +5°C and in high humidity (>70%).
When the cartridge is opened, some transparent liquid may leak out: this is normal for this type of sealant.
