Crack-Tape repairs difficult cracks on flat surfaces and corners. Ten times stronger than paper tape, the tape repairs stress cracks and cracks due to truss uplifts. Crack-Tape cuts easily with a utility knife or scissors, but also resists blisters, tears, shrinkage, and wrinkles. Manufactured from Strait-Flex's patented composite material, it can be used for finishing drywall in high humidity applications. To apply measure and cut to length, then fold in half for corners. Apply all-purpose compound to surface or corner. Press Crack-Tape into the wet compound, adjust to create a straight line, and wipe down with a taping knife. A second coat can be applied immediately. Let dry. Apply a light skim coat, let dry, and sand.
