      I like my mosaic that I am using for my tub surround so much, I decided to use it for the vanity backsplash instead of the 3 inch marble backsplash that came with the vanity sink.  My question is, what do I use to adhere the mosaic to the painted drywall?  My mosaic is glass and metal.  I already have Schluter All-set mortar and Ardex x77, but I have heard some people use a mastic.  What should I use and do I need to sand or otherwise modify the painted wall?
