Good afternoon.
I had to remove some of my bathtub tile, as water had seeped behind the tile and soaked the plaster underneath. I removed the soaked plaster (oatmeal consistency) and dried out the wood lath.
The original tile job is poor (1950's homeowner job), but it will be six months to a year before I can get around to replacing it. What can I use to temporarily patch the bare area? it's about 2' x 2', with wood lath exposed. The patch would need to be waterproof, and hopefully look better than the spray-foam I used for an "emergency" repair.
Thanks
