Repairing Bathroom Plaster for Tiling
I have a section of tiles and plaster fall off in the middle of bathroom bathtub area where the shower often sprays at. I've read through dozens of threads here, and am still unsure on the best thing to do, so I would like advice and confirmation. I have no experience what-so-ever with home repair.
In the picture of the damage, it looks like to me, from the back to the front: metal barbed wiring, some wood-like substance (lath?) plaster (the gray stuff), mortar (white stuff), and then the tiles.
Here's the procedure what I think should be done:
1. Clean out the area by removing loose tiles, mortar, and plaster by hitting it with a screwdriver by hand. Spray the area with water until it's almost dripping wet.
2. Apply SHEETROCK Brand Durabond 90. How many applications? What's the thickness of each application? How long should I wait between applications?
3. Apply a mortar. Is there a specific one I should get? What properties should it have? Something for use in wet areas, and to bond with Durabond?
4. Tile, grout, seal. (Don't know how to do any of that yet.)
Thank you for any advice!
