Question:

When building a tile shower. On walls, can I use poly behind cement board and redguard on top?? Too Much??

My fear is that I will trap moisture where it shouldn't be. Is there such a thing as overkill?

Answer:

No problem. i dont call it overkill. I would rather do it know than wish i had.
