Troubleshooting
Sealant is difficult to extrude from the cartridge
Ensure the nozzle is cut sufficiently and check that your sealant gun mechanism is functioning correctly.
Sealant is not sticking to the substrate
The surface may be contaminated; clean the area thoroughly with a suitable solvent and ensure it is completely dry before re-application.
Sealant is curing too fast or too slow
Curing times are influenced by temperature and humidity. Higher humidity and warmer temperatures will accelerate the process.

Setup, Compatibility & Care
To begin, cut the nozzle to your desired bead width and load the 300ml cartridge into a standard caulking gun. Apply the silicone at a steady pace to ensure an even fill. Once applied, tool the sealant with a smoothing tool or gloved finger within the working time to create a professional finish. The sealant is compatible with most non-porous surfaces and natural stone. For care, keep the area dry for the initial curing period. When stored, keep the cartridge in a cool, dry place and ensure the cap is replaced tightly to prevent premature curing inside the nozzle.
