Grabber 318111 No-Coat Ultraflex 325 Flexible Corner Tape, 100 X 3-1/4

This is the stuff to use on outside and inside corners. LOVE it!

I was a little sticker shocked by the cost of this tape. However, once I tried it, Im pretty much hooked on it. It goes on easier than most other types of drywall corners. I tried this product on advice of some random person I met at Home Depot that swore by this tape, and Im so glad I did.

I used this for off-angle corners (less than 90 degrees) on a cathedral ceiling. Its bad enough trying to make uniform joints with drywall on a hip cathedral ceiling without also having to correct it with nothing but paper tape. The rigid plastic strips make forming a straight joint easy. The blue line down the middle of the flex angle gives a visible confirmation for alignment and mud application. The No Coat refers to that blue line. as long as that remains visible, it is easy to keep the joint visibly straight and professional looking.

Loved every inch of it, easy to form and adhered really well and never moved. Would recommend!

Best thing since sliced bread for diyers

Easy to install and durable to use and mud -used it on angled ceilings and adjusted to the variable pitch

This will definitely get you out of prepacking off angles. This is sometimes wildly expensive on Amazon though. Should cost about $45.

Easy to cut to length, looks very durable

works great

Tried taping and mudding my vaulted ceiling, it would be very difficult without this product. Great to use, I tacked one end with a screw, then tacked the other end with a screw and started in the middle with the mud and worked my way out to each end, which I then removed the screw. Would have been easier with a second person, but that was not available. The angle looks great, the product is great.
