Use & Care
Time and weather will shrink caulking and dry it out so that it no longer provides a good seal against moisture and air infiltration. As a matter of routine maintenance, it is wise to check the caulking and make repairs as needed. Caulking compounds and dispenser guns are available at hardware stores. It is important that you maintain a good barrier to prevent potential leaks, dry rot, or mildew.

Silicone Caulk
Caulking that contains silicone will not accept paint but works best where water is present (for example, where tub meets tile or a sink meets a countertop).

Latex Caulk
Latex caulking is appropriate for an area that requires painting (along the stair stringer or where a counter top backsplash meets the wall).
