I have saw an ad using vinyl to overlay bathroom floor and wall.
Wondering if it’s waterproof ? And will I have any problems ?
they are using a material called SPC. Material is waterproof. Installation method is the same as floor. They will glue the planks on the wall and seal up the wall edge using waterproof silicon. the click system prevent water from seeping through the plank joins. The silicon need to be thick so that it wont wear out and crack easily. If there are using a clear silicon, the color will turn yellowish in long run. If they use a colored silicon, having a thick silicon on all edges is unsightly.
Coming back to durability, I cant comment as we dont want to do it. You may wish to check for Xing Floor or Refloor as I know they are doing that.
