Add a firm vapor barrier to moisture-prone areas in your bathroom, steam room, spa, sauna, or shower with an uncoupling membrane made for tile floors and walls.

Adding tile to your bathroom, kitchen, or other personal space adds a beautiful, sophisticated touch that really brings the room together while adding long-term value. But if you don’t add an uncoupling membrane between the tiles and subfloor or wall you could be opening them up to cracking, damage, and trapped moisture. We want to help better protect these areas with our high-density, super flexible Vivlly Uncoupling Membrane. A smart, durable underlayment that’s both a moisture barrier and a pressure-absorbent layer, it can help keep tile from shifting, fracturing, or breaking while providing a strong, stable base for your flooring or wall tiling. And because it can be used in kitchens, bathrooms, basements, saunas, steam rooms, and beyond, it’s the perfect choice for anyone who needs to add a vapor barrier to your floor or for supporting heated flooring surfaces in moisture-prone spaces.

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

Product seems great. It’s rolled in reverse compared to Ditra or Strata Mat which allows it to lay flat immediately. Very happy with it

Very good product, easy to use, and exactly comparable to the other higher priced similar products!

Material is very very much like Ditra. However, this product is thinner plastic so can be perforated easier. Also should not be creased since the backing starts to pull loose slightly at the crease only. In other words, keep it rolled.

I did bathrooms and laundry room. Used over OSB wood and it works great. Lays flat, easy to cut, absolutely zero issues and far more cost effective than other big name products.

This is the same stuff as the more pricey stuff that you can buy. Talked to a local construction guy, and he said it will do the same job as the higher priced stuff. Literally, it cost 1/3 of what the other did!! It came on time..boxes were quite heavy..but other than that, it is well worth it. Would recommend 👌
