it’s drywall tape and it does exactly what it’s supposed to do. it’s sticky enough to stay on the wall long enough for you to spackle, how ever it does start to slip and move around. i used it to repair a curved doorway and it worked just fine. i would purchase this item again.

I used this product to reinforce my plaster walls after removing wallpaper and before I skim coated with drywall mud. It works great and I'm onto my second roll now. Beginner Tip: The more even you begin to unroll the mesh the better the result when applying it to a wall. So there's a learning curve when using it for the first time. And it seems to rip more the smaller the roll gets. I snipped off the frayed threads around the rip and the mud covered it right up.
