Application
- Apply at an ambient temperature from +5°C to +40°C. The sealant temperature should be +20°C to +25°C.
- Apply the sealant to clean, dry, degreased surfaces.
- 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.
- Tool the sealant in the joint with a damp spatula. 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 mechanically.
Note: the sealant may become stained over time if blue chemicals are added to the aquarium.
It is not recommended to use the sealant when dealing with natural stone (marble or granite), metal surfaces prone to corrosion (lead, copper, zinc, or brass), or concrete, cement, plastered surfaces, as well as when working with mirrors. Do not paint over!
