thinking of using Wedi Board to renovate a shower, this product is great for tile but saw a show room shower that used scratch coat cement, how hard is this to do compared to tiling?
If you mean instead of tile, remember that unless you plan to paint it - concrete or cement is not waterproof. Think of a concrete pool - it requires periodic painting (maintenance). There are a lot of thin solid surface products out there if you do not want to look of tile. Tiling is not that hard as long as you prepare properly and take your time. There are alot of site with tiling guidelines out there - the important thing is to install/prepare the surface properly and seal the grout when you are done.
