Tuff-Tape, from Strait-Flex, is ideal for flat seams and inside corners where paper drywall tape has failed. For novices, Tuff-Tape is easier to apply than paper tapes as it will not soften or sag; and resists blisters, tears, and common cracking problems. Tuff-Tape cuts easily with a utility knife or scissors, is applied with all-purpose joint compound, and will not rust. Manufactured from Strait-Flex's patented composite material, it is extremely strong, will not fuzz-up when sanding, and is four times stronger than paper tape. To apply measure and cut to desired length. For corners, fold in half with the printed sides facing each other. Apply all-purpose compound to flat seam or corner. Press Tuff-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.
