Clean tools in turps or white spirits. Application Lap joints:Apply sufficient sealant to bridge the gap and press surfaces together while still tacky leaving a minimum 2mm film. Cut the tip of the cartridge taking care not to damange the thread, apply nozzle and cut at an angle of 45 with an opening slightly larger than the gap to be sealed.

Apply using a standard sealant gun. Best results will be obtained by keeping an even pressure on the trigger and keeping the gun at a constant angle to the surface being sealed. To ensure a proper bond, always smooth the sealant down with a spatula or piece of wood wetted with linseed oil or white spirits.

An improved joint appearance can be achieved by placing masking tape to both sides of the joint, removing within 5 minutes of application. Adhesive: When using as an adhesive, press surfaces together, pull apart for approximately 10 minutes until sealant becomes tacky, then press together and apply even more pressure.
