Application
- It is recommended to apply the product at an ambient temperature from +5°C to +35°C, including the substrate temperature. The sealant temperature should be +20°C…+25°C.
- Apply the sealant to clean, dry, degreased surfaces.
- Protect adjacent surfaces with masking tape for a neat finish.
- Shape the joint and smooth down the sealant with a putty knife.
- Remove the masking tape immediately after smoothing.
- Remove excess uncured sealant with a damp cloth. Remove cured sealant mechanically.
- Tack-free time is up to 1.5 hours. Ready to handle for a 2 mm thick layer – 48 hours (at 23 °C and 50 % humidity).
- Use paints and varnishes with film elasticity comparable to that of the sealant.
Do not use for joints that are permanently under water (swimming pools, aquariums). Do not apply at ambient temperatures below +5°C or in high humidity (>70%).
