Vivlly1/8” Uncoupling Membrane for Tile, Stone, Concrete, Shower Walls, Bathroom Flooring, Waterproof Floor Underlayment Mat, Anti-Fracture Crack Isolation, 150sq ft - 3.3 ft x 45.9 ft

Exactly what I intended it for. Great alternative to the pricier name brand option.

I bought this as a less expensive alternative to Schluter products. I expected to find installation guidelines, but no documentation was included in the package. I was unable to find a web site for Vivlly. Specifically, I was looking for proper thinsets for adhering the membrane to the floor and tile to the membrane. While polymer modified thinset is generally recommended between wood subfloors and uncoupling membranes, I have applied a cement leveling compound to my Advantec subfloor. Schluter has All-Set, a modified thinset that can be used between concrete and uncoupling membranes, but again, Schluter products are, in my opinion, unreasonably expensive. So I have been looking for alternatives. I could go with unmodified thinset but I would prefer to find a modified thinset because of its greater flexibilty. Unfortunately, I can find no assistance from Vivlly, if there even exists such a company.
