Answer This Question

A:  Absolutely. It will bend to any angle.

by|Jul 11, 2020

A:  Far as I know yes , you will be able to fix those corners, but don't forget to help with some 20 minutes hot mud first to help with any really bed cruket areas, that also will help a lot to make better lines with this tape, is an awesome tape by the way. ,

Answer This Question

A:  Far as I know, yes you can use plus ultra join compound, first compound over the surface you going to put the tape then the tape and over the tape more compound, don't forget to follow the instruction too, and mix the compound before applying that gives you better results.

by|Jun 11, 2020

A:  Yes you can.

Q:Can use spray Adhesive to put up? 3M etc..

Answer This Question

A:  Hi 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.

Q:can you use on outside corners

Answer This Question

A:  Yes. 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.

A:  Typically outside corners have steel or fiberglass because the get dinged

by|May 23, 2020

    A:  I would say no. You would be way better off using a metal or plastic corner bead.

    by|May 20, 2020

    A:  You probably could, but it isn’t really meant for outside corners.

    by|May 23, 2020

      A:  Hi memo, I normally use this for drywall corners, far as i know i don't think you can use it outside, but home depot has metal corners, those are galvanized and also stucco corners, am sure you can use any of those, but no this one, don't forget to rear any instruction if come in there.

      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.
