Create a watertight seal that is secure and long-lasting for your new sink install. The Oatey Plumber's Putty is a flexible setting compound that will not shrink or crack and requires no cure time. The oil-free and non-staining formula is ideal for any natural, porous surface and the plastic putty knife set allows you to easily apply the compound to the various areas. The Loctite Power Grab Ultimate Construction Adhesive will provide the best seal between the edges of the sink and the countertop. The adhesive will not shrink and can be applied on most materials including wet surfaces, setting in 10 minutes and fully cured in 24 hours. A caulking gun will assist in getting an even, continuous bead of the adhesive between joints, and finishing tools will remove any excess amount while giving your project a finishing, professional look.
