Do I need backer board on walls?
I had asked the tub surround have cement backer board on the walls so I could tile partially up (like up to window) from the deck. Add it to the list of things that didn't get done when the house was built.
Now I am ready to finish the master bath (starting with floor so we can use the shower and set the toilet, tub will be done sometime later this year) and am wondering if I can tile over the painted drywall in the tub surround. Bathroom person at Lowes told me if I'm using larger than 8" square tiles I will have problems with drywall (not even green board). I was planning on using 12" square tiles topped by 2-3" bullnose. I want to do all the demo/reconstruction now before I start finishing anything.
