and if not over paint then is it ok to tile over topper? Or over sealer?...dumb questions,I know. But I just gotta ask. Walls now are mudded and taped, just wanna know where I stand...

ya, i'm sure i have in the past, not sumthin i would like to do as a practice, but product literature says not to have loose and peeling paint, however, you will be bonding to the paint, and your job will only be as good as the paint job

I have set tile on painted walls many times, for backsplashes mostly, and on several occasions needed to remove my own tile. It always is very well bonded and damages the sheetrock a lot when removing. This is always with modified thinset and never in areas prone to getting wet.

Thanks guys,
I've tiled over existing paint before and it seems to be locked on pretty good. I hafta paint a portion of the bathroom wall where the topper covers the drywall joints and there will be about 6" of tile overlapping onto the paint.

umm, ...... what's a ' topper ' ??

[Redhawk996]

Topping or taping compound.... the stuff you put on the drywall joints after using tape and joint compound. Topper is a heck of alot easier to sand than the joint compound. I'm not sure how thinset will react to the wallboard compound if its not painted or sealed..

[bctile601]

again the thin-set bond will only be as good as the ' topper ' bond, which on an un painted sheetrock wall is pretty darn good IMHO
