I have an area of drywall that is next to my bath tub that has gotten soft and crumbly. Mostly held together by paint & caulk now.
I'm reasonably sure I understand why. We're getting some water splashing back from the shower and coming down the side of the tub/wall. I know we used the "right" drywall (green/blue), but I'm sure it can only withstand so much abuse (It's not meant for lining your pool).
I'm thinking my best solution is to cut out that section of dry wall and replace it with a chunk of cement board.
My questions now being (which are all inter related):
- Is this the right solution?
- If so, can I do the transition between the cement board and drywall with drywall compound, or do I have crack open a bag of thin-set? - If so, how do I make its finish nice (just run a skiff of drywall compound over it)?
