Can you put tile directly lying on green board within a shower or do you own to also use cement board? ...
Answers: With all due respect to ANY who answer, and after installing multiple thousands of sq. ft. of tile, and remodeling more bathrooms than much else; I'd close to to scrap GREEN Board for use where on earth water directly affects it.
CAN YOU?........... is a query I answer so often here, within this manner..."YES"... but I attach WHY... often.
I'm going to assume GREEN board already exists,,,sigh, and so to opening it out seems silly at lowest. YES...DO concrete backer board, contained by any area where on earth water will be an issue, when tile is the finish fabric.
I want to impress on you that STUFF is "HYPED" in demand to sell it.
I haven't used Green Board contained by a very long time; and the merely call back I ever get are, "Can you come and do MORE work."
