Silicone gun
A silicone gun is a caulking gun for applying sealant, silicone, adhesive, filler, or mastic from cartridges. It may have a rotating barrel, heavy-duty mechanism, and trigger for smooth beads.
- Ensure the surface is clean, dry, and free from dust before sealing.
- Cut the cartridge tip to the desired bead size, then pierce the inner seal if required.
