Maintenance
Time and weather will shrink caulking and dry it out so that it no longer provides a good seal against moisture and air infiltration. Caulking may need to be touched up by the homeowner once each year.

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 counter top).

Acrylic/Latex Caulk: Acrylic/latex caulking is appropriate for an area that requires painting. (For example, around the windows or along baseboards.)

Limited Warranty
Caulking is a Homeowner maintenance item.
