Can I Repair/Reuse old mortar bed
I am replacing the tiles on my bathroom walls, including the tub surround. My home was built in the 1950's and the tiles were installed over a mortar/cement bed. The mortar/cement is very solid--about 2" thick, and the metal lathe is extremely sharp. It would be very difficult, messy, heavy, and dangerous to remove it, and I would like to reuse it.
The problem is that the mortar bed has holes every four inches. I am not sure if water linked through the grout and eroded the bed at these locations, or if this is the way it should look. So imagine a cement wall with coin-sized holes every 4 inches in sort of a grid pattern.
Can I just patch up these holes with plaster, or cement, or mortar and reuse it? If so, what should I use to patch the holes? and, once repaired, what should I use to apply the new tile to the old bed?
Thanks much, Best regards---B
