Product Use

Use as a flexible barrier between horizontal and vertical surfaces or any other changes on walls or ceilings. Mask both sides of the joint. Remove tip-cover, cut tip on a 45° angle to desired diameter and puncture the seal inside the tube. Place in a caulking gun and apply using steady, even pressure to completely bridge joints. Smooth by dry tooling the bead and remove masking tape immediately. Wipe off any sealant on the face of the veneer with a paper towel before surface sealant skins over.
