Create a watertight seal that is secure and long-lasting for your new sink install. The Oatey Plumber's Putty is a soft, flexible setting compound that will not harden, shrink, crack, or crumble and will not stick to your hands. Its fungus-proof seal is ideal for sink drain flanges, frames, and strainers and the plastic putty knife set allows you to easily apply the compound to the various areas. The GE Supreme Silicone Caulk will provide the best seal between the edges of the sink and the countertop. The caulk is shrink and crack-proof and ready for water in 30 minutes. With stronger adhesion and more flexibility, the sealant adheres to most surfaces that are constantly exposed to moisture. A caulking gun will assist in getting an even, continuous bead of sealant between the joints, and finishing tools will remove any excess amount while giving your project a finishing, professional look.
