Application
Prepare all surfaces before application, ensuring they are free from contaminants like dust, grease and make sure it's clean and dry. You can apply this to slightly damp surfaces which are not saturated.
- Apply using a standard sealant gun.
- When sealing deep joints, use foam and backing rods to minimise silicone wastage.
- Cut the top of the nozzle without damaging the screw thread
- Screw on the nozzle and cut at a 45° angle, ensuring the hole is slightly larger than the hole to be filled.
If the intended application area is bitumen or stone, prime the surface before otherwise, it will hinder adhesion.
