Curing time can vary depending on bead size, temperature, and humidity. Typically, it begins to skin over within minutes and can be tack-free within an hour, with full cure taking longer.
Once fully cured, the sealant can generally be painted over. It is advisable to test on a small, inconspicuous area first to ensure compatibility with your chosen paint.
Unopened tubes should be stored in a cool, dry place and typically have a shelf life of around 12-18 months. Always check the packaging for specific expiry dates.
The 290ml tube is designed to be used with a standard caulk gun for easy and controlled application.
Uncured sealant can be wiped away with a damp cloth or cleaned using an appropriate solvent. Cured sealant will need to be removed mechanically.
Ensure the inner seal of the tube is punctured and the caulk gun is properly engaged. Check that the nozzle is not blocked.
Verify that surfaces were clean, dry, and free from dust, grease, or contaminants before application. Ensure the material is compatible.
Adjust the pressure on the caulk gun and practice on a scrap surface. Ensure the nozzle is cut to the appropriate size for the gap.
