Go to the Schluter website. They have their installation manual you can download, plus helpful videos and how to's for just about every situation their products cover. I have used their shower kits and their ditra for the floors and have had very good results. However, I would hesitate to use any of their products for a situation they don't say it will work for. Their products are designed to be installed as a system, in a particular way, with specific type thin sets.
