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 will never use anything else on corners again. Lay it on some ram board coat it with mud stick it on the corner and trowel . Done.

Best thing since sliced bread for diyers

This is an amazing product. Does what it says. Just make sure you do the skim coat on the edges after setting

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.

I like this tape. The description says you can use it for inside or outside corners. Its rather pricey so using it for inside corners is wasteful in my opinion. One thing I found is that in order for this to stick to the wall properly, you need to ensure that the wall is filled in behind the tape fully. You cant get by with one edge not aligning perfectly with the other edge. This takes some getting used to but after you play with it a while, youll get the hang of it. I did use this on angles less than 90 which I feel is this tapes forte. My opinion is it beats old metal corner bead.

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

I use this and the 450 for all my outside corners. Its super fast and really easy to install. The finished corners are really strong and dont chip or flake off when hit like traditional corner beads. The only drawback is the specialty tool required to make the installation go faster. Still the best no coat product Ive used so far.

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.

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.
