I am remodeling my bathroom and was wondering... Can I place ceramic tile over drywall? I am hanging concrete board in the shower area, but was wondering about the rest of the walls. I am going to be using 9" x 6" tile on the entire walls and would rather not hang concrete board over the entire thing (regular walls not in shower) if I don't have to. |

BAD juju. Do not do. Unless you want the tiles to fall off in a few months. Drywall is soft and weak. Grout lines are very brittle, and will crack with the slightest flexing of the wall. Even if the tiles don't fall off, the grout will. EDIT: If you put tile on just a few inches of drywall with the rest being cement board, as the previous poster did, it may be OK, as long as it's not an area exposed to water or high moisture (grout is very porous). |
not if you are using the new polymerized mud and sanded caulk to seal the edges. |

Yeah, 3/4" may be OK for a dry environment with no kids around, but the typical 3/8" to 1/2" is way too thin for me. |
I have alway seen 5/8" green board her in AZ for our bathrooms. |
HD switched from green to purple. |
PERFECTLY FINE!!!! AOK good to go! You can tile sheetrock with no problems. You have to use MASTIC (tile adhesive) NOT thin-set mortar. Thiin-set mortar is used for floors and natural stones. Most building codes require Green Sheetrock (commonly called MR, or moisture resistant) to be used in any room where there is plumbing/moisture. If it is a half bath with no shower you can use plain sheetrock with no problem...i do EDITED: When I lived in Key West (after the hurricane that devistated homestead and during hurricane George 1998-1999 when all of the new FL building code was implemented)...I worked for a licensed general contractor there. 3/8 sheetrock is ONLY for cosmetic (covering over paneling of old walls) 1/2 inch is for normal resedential. We only use 5/8 in NY for Commercial (fireproof rating) and in boiler rooms. Probably same in FL Also... thinsetting wallboad to sheetrock serves no purpose and adds more chance of falling off of the walls if not properly installed. Cement board (wonderboard, tilebacker) is used around tub area and on floors (on top of adequate subflooring since it will not support weight) is areas that will be exposed to WATER not moisture. It is reccomended that you prime and paint before tileing. |
