ABSTRACT:
A caulking tape for sealing joints such as around bath tubs and shower bases. A bead of butyl rubber based sealant permanently adheres to one side of a flexible strip of opaque polyester film. The tape is wound in a spiral roll and one side of the polyester strip is coated with a siliconized release agent from which the sealant releases to permit the tape to be drawn off of the roll for use. The bead of sealant is set back from the edges of the carrier strip so that it does not squeeze past the strip when the tape is applied and pressed against the joint. When the tape is fully applied to the joint, the sealant provides an effective seal and is completely covered by the attractive polyester strip to enhance the appearance of the caulked joint.
