Rated 5.0 out of 5.0 by Best Corner Tape Around I've used this tape for a while now and nothing compares for price, ease of use and dependable results. It goes on easily, cuts like a charm and because of the way it's designed usually only needs one good coat of compound and a little touch up sanding for a smooth professional corner every time. Try to cut it the accurate length cuz it's not that easy to cut it on the wall. Then coat the corner with a thin layer of compound or "butter" the tape itself after cutting and bending into a 90 degree corner. Stick it in place and carefully, with a 12" wide compound knife, apply a good even layer of compound and keep going over it until it's smooth and perfect. September 29, 2014
Rated 5.0 out of 5.0 by Inside corner magic I'm old school and have always used paper tape over anything else. This time I decided to try something new and was impressed. It’s strong and has good reinforcement in the corner, doesn’t fuzz up when sanding, and easy to use. Make sure printed side faces out for both inside and outside corners. I was able to get all the inside corners done of a small room in one day. I highly recommend this! April 24, 2013
Rated 5.0 out of 5.0 by Awesome Stuff! I had to do so many 90 degree angle corners when re-doing the entire upstairs ceiling with new drywall. This stuff works and lives up to its promise of being twice as fast. It's literly perfect after one coat. I would highly recommend this product for inner corners. I didn't have the opportunity to do an outer corner with this project, but assume it would work just as good. Thank you to whoever invented this product! March 6, 2013
Rated 5.0 out of 5.0 by Nice edges, inches or cm printed on tape I'm just an amateur when it comes to this stuff, but I've found this easy to use. The edges are kind of perforated so that you can get the mud impregnated into the paper. Also, Inches and feet are printed on the tape as well as in cm. so that you can easily cut off a piece a specific length. This stuff does cost quit a bit more but I went back for a second box.
