Asked by DAVID May 23, 20201
AnswerHi David, all depends on the surface you going to glue the tape, glue may work. but definitely use some taping compound first, instead of glue. I been using it and I normally apply a thin layer of taping compound first then another coat on top, keep in mind the results may go different, with the compound gives you a change to adjust any defects then glue , to me is easier compound then glue. am not saying not to use the glue.
can you use on outside corners
Asked by memo May 19, 20205
AnswersYes. I used it for some 135 degree angles, after I failed with regular paper tape. It should work with almost any angle and I think Straitflex should make that more clear in their product description.
Can this be used in a 3 way corner. I’m referring to a vertical wall corner and two ceiling to wall corners.

I'm not a professional drywall guy, just someone who every once in a while puts some up in a game room, wet bar or garage. I thought I would give this product a try & I found it to be pretty good. In the attached picture I used this product in two of the corners shown & one corner was done by a professional working in my garage. I suspect no one could really tell the difference. The only negative is that it seems a little expensive.
It’s easy to use and it is a perfect solution to fix gaps in the corners.
