Surface preparation
All surfaces must be clean, dry and dust free.
All loose or flaking surface coatings, and old sealant and mastic joints, should be removed before application.
Highly porous substrates such as new plaster should first be primed with a dilution of CAULK ONCE with water at a ratio of 1:2.
Can be applied to slightly damp surfaces.
Application
Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut cleanly 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 gun trigger and keeping the gun at a constant angle to the surface being sealed. Smooth down within 20 minutes of application using a wetted spatula, piece of wood or wetted finger. Care should be taken at this point not to saturate
