Installing tile in my laundry room. put down the cement board with a mortar/thin set base under it, then nailed it down according to manufacturer's instructions. The mortar/thin set totally dried then I had to do a few loads of laundry before I was able to put any tile down. Unfortunately one of the hoses hooked up to the washer leaked and soaked the cement board and I'm sure also the sub-floor. Do I need to rip out the cement board and re install before I install the tile? obviously I would need to ensure the floor is fully dry before I install the tile. Thanks
You shouldn't have to rip it out. I would let a fan run on it for a few hours just to make sure it is totally dry.
I do not think you need to rip it out. Just let it dry for a week or so before you install the tile.
