I'm not personally using this stuff, but bought it for my tile installation contractor who is installing a tone of Durock at my house in preparation for large format tile. I had bought some stuff from one of the big box stores that was fiberglass that only came in 50 foot rolls, and the contractors like this stuff WAY better. So much more that they more or less begged that I just got more of this stuff. Said it was some of the best joint tape they had ever used ..
