I ordered my cultured marble shower today and want to make sure all my ducks are in a row before it arrives. I have a few questions about backerboard.
1.) Is durock sufficient backing material. I had read somewhere that it may not be strong enough by itself and should be used in conjunction with greenboard for strength. Is that so?
2.) Each wall of my shower will be covered by one solid cultured marble panel. Is a vapor barrier needed?
3.) I'm still not clear on what material I should use to imbed the fiberglass tape when I tape the seams of the durock. I will need to make a smooth surface. I had read to use thin set mortar, but it seems to me that if I used thin set I wouldn't have a flat surface. What am I missing?
Thanks in advance for your advice. This forum is a lifesaver.
