eXact color™ is the easiest and fastest way to create custom colored caulk - no tools required. Simply mix in any latex paint, stain or universal pigments for an eXact color match. eXact Color is excellent for creating contrasting colors or perfectly matching caulk to custom colored paint. eXact Color is a high-quality, super-elastic sealant with powerful adhesion that won't crack or pull away. It can be applied in joints up to 1/2" wide indoors and outdoors. The 9.5 oz. plastic cartridge (final yield after mixing) includes everything to make a custom colored caulk. Plus a cap for storage.
