eXact color is the easiest and fastest way to create custom colored caulk with 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) comes with everything included to make a custom colored caulk: 1 activator pack 1 measuring syringe 1 nozzle and 1 clear cap.
