Can we tile over rotten sheetrock?

Question

We had a leaky faucet that caused water damage to the sheetrock behind the kitchen sink. We put in a new faucet and are now planning to tile over the soft sheetrock. Is this o.k.?

Answer 1

I've seen on home improvement shows where they have had to replace the whole wall because of the rotted wall. I would highly recommend doing the same and just buying the new sheet rock and starting over. Much better doing it now then having to replace later on and having to buy more stuff later and having to pay for more material then and slapping yourself on the forehead and asking yourself why didn't I do that then? Good luck and have fun tiling, even though it's hard work, i've heard it's worth it in the end!

Answer 2

You need to replace the board behind the tile. The tile is relying on that board to hold it up. If it disintegrates, and it will, then there goes all that new tile too. You have to put up green board. This is the name of special wall board designed especially for high moisture areas. The entire shower area must be covered in this, not just the wall you're replacing, or you will be back again, replacing the rest of the walls at later dates.

Answer 3

Do not put good Sheetrock over the bad.
The rotten Sheetrock will cause the good material to rot also which would cause a bigger mess than you had before.

Answer 4

NO! You must have a sound surface to apply the tile. Green board is OK for a wall application. If you want the tile to last more than 6mo you have to fix the wall you can't just cover it with tile.

Answer 5

the sheetrock has to be removed. Tile must have a stable surface.

Answer 6

if you want mold to be near your faucet but thats a health risk and can kill you and bacteria grows there so therefore make your decision from there
