Sikasil C is a 1-component, neutrally curing silicone sealant, suitable for indoor and outdoor use. Sikasil C is suitable for sealing glass, metal, wood, acrylic, polycarbonate and ceramic tiles. Underground condition: Clean, dry, even, free of grease, dust and loose parts. Paint, cement skin and other weakly adhering parts must be removed. Sikasil C is supplied ready for use. After appropriate cleaning and substrate preparation, place the cartridge in a hand or compressed air gun and squeeze Sikasil C into the joints, ensuring that contact with the joint sides is ensured. Avoid air pockets. Use masking tape if sharp and very precise joint lines are desired. Remove the tape while the sealant is still fresh. For a perfect surface finish, smooth with a wetting agent.
