drywall which got wet
Due to a leaky shower stall ( since replaced) some of the nearby
drywall now has a 'puffy' look. I guess the paper coating has expanded or sumthin'. Can I lightly sand it and paint over it? What would you suggest? Thanks. |

What would you suggest? Thanks. Not much can be done (satisfactorily at least) w/ drywall that has been wet other than replace it. I second that emotion. Replacement isn't too terribly traumatic, depending, of course, on your skill level and sense of adventure. Just a few tools (measuring tape, straightedge, utility knife, hammer or screwdriving drill, drywall finishing tools), some "mud" and you're good to go. -- Made From Pears: Pretty good chance that the product is at least mostly pears.

If the drywall is breaking up, replacement is the only sensible option. But if the water damage is minor/cosmetic, a simpler fix might be very viable. Sand and then seal the area with an oil based primer (Kilz or similar). Then paint. It's worked perfectly for me a couple of times. Those repairs are completely invisible and they were made several years ago. -- |~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~| | Malcolm Hoar "The more I practice, the luckier I get". | | Gary Player. | | http://www.malch.com/ Shpx gur PQN. | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~ |

If it is spongey to the touch and the paper has seperated from the drywall , getting it "wet" again by painting it will make the paper bubble up and the drywall possibly crumble...Without photos only you know how bad it is...Good luck... |

What would you suggest? Thanks. How bad is it? If really bad, will have to be replaced but that's not as hard as it sounds. If just a bit bubbled (can barely feel it) let it completely dry then consider possibly putting a 'bathroom type' (vinyl sort of) wall paper over it after sanding smooth *lightly* through any bubbled paint. It will have to be very minimal damage or the wallpaper will bubble and not adhere, or you'll see imperfections through the paper. Don't use the standard 'paper' but stuff meant for bathrooms. it's a bit thicker and can handle a reasonable dampness load. Also it's washable. |

If there is no tile on it then ripping out a patch of drywall to the studs and replacing it is just as easy as sanding it IMHO. Cut the bad drywall out to the nearest stud centers, screw on a patch, mud/ tape it, sand, paint. Mold is a living organism and will only multiply over time. |

Cut the bad drywall out to the nearest stud centers, screw on a patch, mud/ tape it, sand, paint. Mold is a living organism and will only multiply over time. Around a shower you should be using BlueBoard or GreenBoard (I think they are the same). They are a special drywall made for wet areas and hold up better. Standard drywall is not a good choice around showers. I would rip out all the drywall on the walls around the whole shower, and replace it with the blue/green board. You likely got mold in there. If you do, wash the studs with bleach water and let them dry. Hopefully there are no tiles to replace. Patching soaked drywall will only extend it's life, but is not a permanent solution, and if there's mold, it's still there. (and there probably is mold). You dont have to mess with the ceiling, unless it's damaged too. I have a question to add to my reply. Maybe someone else can answer this. When using blue/green board, is there a waterproof joint compound made for it? ANYONE????? I'd probably use the fiberglass joint tape too, not the paper! Cement board is what you want in wet areas. The greenboard was used there for a while, but it doesn't work much better than plain wallboard. Use the greenboard in the _rest_ of the bathroom to fight steamy air, and use cement board in the shower and around the tub. With cement board, you tape the seams with mortar and fiberglass tape. I recommend you put a waterproof membrane behind the cement board. -- Steve Bell New Life Home Improvement Arlington, TX USA |

In which case, you want to use SOLID VINYL wall covering. (or mylar foil) Not familiar with mylar foil but the vinyl yes. Thats what I'm used to seeing recommended for bathrooms. I got the impression the 'wall' he was talking about wasnt one that would normally be in a direct line of spray, and was only gotten wet due to the plumming accident, hence the suggestion. |

If you insist on only sanding and painting over it, prime with oil base primer. This will keep the paper from getting wet and bubbling further when it gets wet again from painting/mudding. Question, have you had much luck putting latex over oil based primer? I ask because my Mom taught me that's bad juju. Pretty much put oil over oil. It was a bear when we had to paint a chair rail and window setup that was oil based before and we needed to put latex over it. Had to sand the dickens out of it to make it work. |

In one place I got there was a bathroom that was painted over wallpaper with latex. The paper had bubbled. Remove loose stuff. Oil prime areas to be mudded/patched (water in mud will further bubbling of wallpaper). Mudd and smooth Prime everything with oil base. Paint with latex. Worked like a charm...whether it's suppose to or not. |

This will keep the paper from getting wet and bubbling further when it gets wet again from painting/mudding. Question, have you had much luck putting latex over oil based primer? I have. It works fine. (Assuming you use a good paint over a good primer.) Remember that the primer finish is very flat, which gives a good "tooth" for subsequent coats to adhere to. I also know a professional house painter who does that (oil primer/latex topcoat). And he knows a *hell* of a lot more about paint than me. I ask because my Mom taught me that's bad juju.

Had to sand the dickens out of it to make it work. Are you sure the oil-based paint you were painting over wasn't primer but was glossy or semi-gloss? You're going to have problems painting over *any* type of non-flat previous coat; that's why you're supposed to use a deglosser (or scuff the finish) first. -- Made From Pears: Pretty good chance that the product is at least mostly pears.

Pretty sure it was a gloss oil base we were covering. Painful job to do! I was about 11 at the time and not big enough for the heavier jobs yet so go that one. Best I can recall there were 13 windows to deal with alone upstairs and not sure how many in the back of the basement. Took me about 1.5 hours of reasonably hard work per window to get it sanded down. (Mom flipped houses for a living then, not that that term existed then). |
