Certainteed No-coat Ultraflex Flexible Drywall Corner Tape, 3.25 In X 100 Ft

CertainTeed No-Coat Ultraflex Flexible Drywall Corner Tape is a high-performance solution for reinforcing and finishing drywall corners in residential and commercial projects. This flexible corner tape is engineered to bond uniformly with joint compound, preventing cracks, separation, and edge failure that plague traditional rigid tapes. Whether you're working on new construction, remodeling, or repairs, this tape delivers professional-quality results by accommodating building movement from settling, lumber drying, and temperature or humidity shifts.

The tape's engineered high-impact copolymer core and memory-free hinge allow it to conform perfectly to any angle—90-degree corners, cathedral ceilings, vaulted ceilings, or off-angles—without pre-creasing. Its ultra-thin tapered edge simplifies installation and accepts paint and texture uniformly without alligatoring, wrinkling, or fuzzing after heavy sanding.

Features and Benefits

• Flexible Core Design: Forms to any angle without pre-creasing, eliminating the need for manual bending and ensuring consistent contact with joint compound.
• Uniform Structural Bonding: Prevents cracks and callbacks by resisting separation from walls, denting, and damage from structural shifting caused by settling and lumber drying.
• Versatile Application: Works on inside and outside 90-degree corners, off-angles, cathedral ceilings, trey ceilings, vaulted ceilings, and problem framing situations.
• Superior Edge Performance: Ultra-thin tapered edges reduce installation difficulty, while 1/2-inch flaps act as a lockdown mechanism to eliminate edge cracking.
• Paint and Texture Ready: Accepts any wall texture or paint uniformly without alligatoring or wrinkles; resists fuzzing under heavy sanding.
• Durable Paper Backing: Joint tape paper backing provides unsurpassed bonding to joint compound for long-lasting results.
