DOWSIL General Purpose Silicone Sealant is a general application acetoxy silicone sealant, designed for:

- Glass to glass adhesion and sealing
- Ceramic materials adhesion and sealing
Remove all residual dirt, residual and old sealant thoroughly. Wipe off grease and dirt on the surface with a piece of white cloth with solvent, then wipe immediately with another piece of clean cloth, so as to remove the residual solvent and dirt on the surface.
Masking will ensure a clean, neat appearance and reduce clean up by protecting surrounding areas from excess sealant.
Cut the nozzle at 45o and screw onto cartridge, and place it into caulking gum. Air-operated or hand-operated caulking guns can be used. Apply sealant into the base of the joint so that it completely fills the joint, wetting both sides. Do not simply lay a bead on the surface as the sealant will not penetrate the joint under its own weight.
Tool the surface of the joint immediately after sealant application to provide a smooth even finish and to ensure the sealant wets the sides of the joint. A tool with a convex profile is recommended to keep the sealant within the joint. Do not use soap or water as tooling aids. After a skin has formed, do not disturb the joint for 48 hours.
