Are caulks & sealants mold & mildew resistant?
By nature, caulks and sealants will create bonds that are mold & mildew resistant. However, they do not stop mold that is already growing in an area or prevent mold from growing around the caulk or sealant. You need to be sure to follow some pre- and post-application steps to make sure mold & mildew growth will be prevented in the area of application.
