Strait-Flex® Tile-Tape®

Designed for tile, marble and granite and water and mold resistant

Produces straight, strong, and water-proof inside, outside and off-angle corners.

Application(s): Drywall

Tile-Tape® prevents leaks caused by common grout cracks. Tile-Tape is applied over seams and corners formed by tile substrate and mold resistant boards in wet areas. Tile-Tape is manufactured from a composite material giving the tape strength and mold-resistant qualities. Two times stronger than paper or mesh tape, it will not cut or snag when applying tile setting compound with a notched trowel.
