Are there concerns re: installation of glass mosiac on "used" drywall?
I plan to install a 6-inch horizontal strip of glass tile, 1-inch
squares, on "used" drywall. I removed a strip of existing tile,
located about 8-inches above the counter, from the counter-to-cabinet
ceramic tile backsplash. The old mortar has also been removed. I
also plan to use the tile manufacturer's recommended products for
thin-set and grout. Thx.
