I built a shower enclosure. Over the drywall I applied MAPEI membrane strip in the lower portion of the wall with MAPEI flexible waterproofing membrane as adhersive. You can see the subtle shape of the fabric strips in the photo. And then I applied MAPEI flexible waterproofing membrane everywhere with a roller and trowel. When it all done, I found lots of air bubble under the membrane strip. My question is: If I apply the tile over such a condition, will the weight of the tiles tear down the fabric so the layer of tiles will seperate from the wall? Thanks very much in advance.
