1. Cut the tip of the cartridge taking care not to damage the thread. 2. Apply nozzle and cut cleanly at an angle of 45° with an opening slightly larger than the gap to be sealed. 3. Apply using a standard sealant gun. Best results will be obtained by keeping an even pressure on the gun trigger. 4. Smooth the sealant down using a smooth down tool. Any mistakes can be rectified by removing sealant with a damp sponge or cloth before re-applying.
