Removing Mold From Painted Walls

RE: Removing Mold From Painted Walls Post By (Guest Post) (09/13/2007) Thank you so much. I am going to attempt all of these solutions and I will give you an update. Thank you! RE: Removing Mold From Painted Walls Post By becks (Guest Post) (08/01/2007) I have had issues with mold coming back for 4 years in my apartment. I have used everything from bleachwater to Tile-x, i even tried that Killz stuff, nothing worked. I have no window in my bathroom to vent the moisture from the shower and the exhaust fan doesnt seem to do the trick. I even tried putting an oscillating fan in there to help out a bit and it still comes back. The maintenence guys didnt help any either when i told them about it, they just said use bleach. I have no idea how to get rid of this problem, aside from moving to another apartment, and if anyone has something that will be helpful I would like to hear about it please. RE: Removing Mold From Painted Walls Post by Cyinda (191) | (06/15/2007) Contact The mold is BEHIND your walls or wallboard... I had a whole room that was TOTALLY INFESTED with mold. This was because when I bought this place, the previous owners had built a "sun porch" onto my mobile home with NO window sills & because the windows were huge & single pained, the windows constantly sweated (over a quart a day), Thus, all of that water was dripping BEHIND the walls, all day, every day, over the course of many years. I thought I would have to tear the small addition down because the mold was everywhere along the bottom 2 feet all around 3/4 of the room, until I did the following. HERE'S WHAT WORKED FOR ME: (& yes, I know bleach is toxic, but this needed to be done with something that was STRONG!) 1) After talking to an expert on mold. He recommend I put 3 or 4 parts of water with one part of Bleach & put this into a spray bottle (OPEN THE WINDOWS for ventilation) & spray the bleach water mixture onto the walls. Do this for 2 days in a row (this is to open the "pores" of the wood or sheet rock) Then, on the 3rd day: Take the same bleach-water solution, but this time (use gloves) apply it with a sponge straight to the wall. ----> NOW HERE'S THE IMPORTANT PART: 2) Wait 2 weeks & DO IT ALL OVER AGAIN! (the spraying & sponging of bleach/water) This is because there most likely are brand-new mold spores that have formed in the past 2 weeks that you can't see that have sprung up since you last bleached. 3) Then, after a few days of the walls drying the second time, apply a good mold inhibit primer like ZINSSER 123. Apply at least 2 coats or MORE. 4) Then put on at least 2 or more coats of paint with a high quality paint. (I used semi-gloss) 5) I then covered the painted area with stick-on VINYL (wood-looking) floor tiles from the dollar store ( Dollar Tree, 3 tiles for $1). This REALLY sealed in the walls. 6) I then caulked between the vinyl tiles with a matching tan colored caulk. 7) Fix the problem... What is causing your mold problem? Fix this! Moisture is getting in there form somewhere! You can also install a dehumidifier. I build no drip window sills out of hard plastic. (The kind you use to line your flower beds) Then calked them. ---> This may sound like quite a hassle... & to tell the truth it WAS!... But, believe me, I couldn't even use that room except in the summer due to the heavy amount of mold & it's nasty smell... but now, that I've sealed the walls... I can use that room & I just love it! ---> IMPORTAINT: My mold wasn't the toxic mold you hear about on TV. Yours may be... Use care around any household mold & keep your kids away from it too! If you have any questions, call your local Health Department. ** My "sun-porch" turned "craft room" it totally made of plywood, the wood held up to all the bleaching. Wallboard may act differently.

Check it out! www.moldzyme.com RE: Removing Mold From Painted Walls Post By Dimitri (Guest Post) (05/11/2007) Sorry folks but that's some serious misinformation. Killz does not kill mold. Even bleach only has a temporary effect if you dont fix the mold-growing conditions. You need to kill the mold with an EPA registered fungicide/mildicide (mold killer), remove any porous materials that have mold deep within them (carpet, sheetrock, insulation), and maybe most importantly you need to fix the source of water or humidity that contributed to the mold forming. Fungicide or lack of moisture can kill the mold, but even dead mold spores left in the area can trigger allergies. Again, if the wall is wet from within, just killing/wiping/painting over it will not fix the problem. It will grow back, and could spread. RE: Removing Mold From Painted Walls Post by tedsmom (507) | (01/24/2005) Contact The only way that you are going to stop the mold from coming back is to paint Kilz over the spot and then repaint. Kilz is white in color; therefore, you do have to paint over it; however, it will kill the mold. By the way, Kilz is the brand name and any paint dealer should have it. RE: Removing Mold From Painted Walls Post by Jo Bodey (288) | (01/24/2005) Contact Mould grows where there is moisture so the 'cure' is to prevent the moisture collecting/condensing on walls and creating the environment where mould spores can settle and breed. If its at the bottom of a wall it may be rising damp, because of an ineffective or breached damp proof course, (often flower beds built up outside the wall allow damp to seep in above the damp proof course) In this case, to prevent the mould you need to repair the damp proof course, (expensive), or remove the structure that is allowing the moisture to bypass it. In cooler damp climates like Britain the atmosphere is often laden with moisture and this can be compounded by the moisture produced within the house - from the kitchen, bathroom and given off from the breath and skin of human bodies. The answer here is to increase ventilation, whether through opening windows/ doors, especially after bathing/showering, or have an extractor fan installed. Raising the internal temperature of bathrooms while showering to heat the walls slightly will also prevent the moisture suspended in the air from condensing out when it hits the cooler surface of the wall. But you must then ventilate to remove it from the house. A bleach solution, (as directed on the bottle), should remove the mould, kill the spores and whiten/lighten the stain. It will recur unless you sort out the ventilation problem, even if you paint over the stain, although some paints have a built in fungicide to discourage mould growth.

RE: Removing Mold From Painted Walls Post By Mitzi (Guest Post) (01/24/2005) Try using Tilex. It works wonders on mold and mildew. I wouldn't be without it! RE: Removing Mold From Painted Walls Post By Shari (Guest Post) (01/24/2005) Painting over the mold or cleaning it will do absolutely no good if the mold started underneath the wall - you might have mold growing underneath in the insulation - if this is the case, you need to get the damage fixed fast before it spreads further, and if it happens to be that toxic black mold, your health is at stake too. RE: Removing Mold From Painted Walls Post By Elisa (Guest Post) (01/24/2005) I don't know what kind of painting products that are available to you in England, but in the United States there's a brand of paint mildew killer called "kills." You paint the Kills on the problem area to kill and seal in the spores and then paint over again with the color you wish.
