I’m doing a bathroom remodel, which means removing the old (ugly) 4 in. sq. ceramic tile from the walls and then demolishing the underlying thickset mortar bed. It’s circa 1950 when they made things to last. The mortar is attached to a metal lath which is placed over 3/8″ thick gypsum board (the kind with the holes in it); both lath and board are nailed to the studs. After removing the tiles, I’m wailing on the mortar bed with a 5 lb hammer to crack the mortar then chiseling it off until I get down to the lath, which I can pry off. Great exercise but not much fun. Does anyone have a better idea?
