Areas For Use
The surfaces to be must be clean, dry and free from dust, grease and other contaminants.
Priming is generally not required, although we always advise testing small areas prior to use.
Joint design should be as follows:
Minimum width: 6mm. Movement capacity will be impaired if the depth of the joint is greater than the width. For maximum movement accommodation, it is recommended that:
Maximum joint width without slumping is 40mm. When flashing into concrete walls with a wider joint, always fix the lead with stainless steel screws and plugs prior to applying the sealant.
All joints should be designed so that the seal is placed in a position which does not retain water or form a water trap. Triangular fillets should be no less than 12mm across the face and should be finished with a flat or convex face.
Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut at an angle of 45o 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. An improved joint appearance can be achieved by placing masking tape to both sides of the joint, removing within 5 minutes of application.
