Problems grouting over sheetrock?

peterbinderMay 30, 2008

I'm remodeling my poweder room and was planning on creating a mosaic (approximately 2' x 2') on the wall, matching the design on the floor. I'll have my design adhered to a screen which will then be attached to the wall, but my question is this: Will the moisture from the grout seep into the sheetrock? Do I need to prep the sheetrock in any way? Any suggestions would be much appreciated.

Thanks,

Peter

When I first started mosaicing I read in one of the many tutorials on the net that it is unadvisable to mosaic onto sheetrock. If I wanted to mosaic on the wall, I'd use backerboard - the concrete board used on countertops in kitchens and in bathrooms. When I dismantled my bathroom backsplash counter b/f I mosaiced it, there was a base of the diamond mesh and mortar. IMO you could go either way - use the hardibacker or put the wire mesh on then use mortar for your mosaic. Show us pictures as you work, please.
