How to use
- It’s recommended to apply the product at an ambient temperature from +5°C to +40°C. The temperature of the sealant should be +20°C… +25°C.
- Apply the sealant to clean, dry, degreased surfaces.
- Protect surfaces with masking tape to ensure an accurate application.
- Cut off the tip of the cartridge above the screw thread, screw on the nozzle, unscrew the nozzle cap and cut off the nozzle diagonally (at an angle of 45°) according to the diameter of the joint width.
- Use a cartridge-operated gun for application.
- Smooth down the sealant in the joint with a wet putty knife. Remove the masking tape immediately after smoothing.
- Remove the sealant from tools and surfaces using a solvent (white spirit, or acetone) before the sealant has cured.
- Remove cured sealant using mechanical methods.
