Troubled Basement Walls - Mold


Hello all,
My basement walls have lead paint on them. I'd like to just paint over them with some waterproof paint or something, but in the mortar, the paint is loose and chipping. I don't even want to mess with it. In some areas, the paint has mold on it as well.

Basically, I'm looking for a solution to simply cover up the walls completely to eliminate the lead and mold once and for all.

Does anyone know of any options? Is there something that can be sprayed over the top? Spray on concrete? I'm desperate.

Thank you so much, your replies and suggestions are much appreciated.

Troubled Basement Walls - Mold


I've used a product in mold remediation called Shockwave. Guaranteed to kill 99% of mold and spores. Just spray it on.

A strong bleach and water solution has also been used although unsure of how effective it is.

I would seriously advise against just covering it up before treating it. Mold LOVES to be covered up and will grow like wild fire in a enclosed space.

About the lead based paint. I assume you had it tested at some point therfore know it's lead paint. Since it's been tested you have to by law disclose this fact when you go to sell it. If you just cover it up it may come back to bite you. Also if there are children around it's cause for concern. Have you asked for a estimate yet on how much it would cost to take care of the problem properly? It might be worth it to get a couple. All remodelers are now required to have lead training and certified to test and repair for lead based paint.

dk: I'd second the vote to remove it. Sweeping mold, etc, under the rug will bite you in the buttinski, if not someone else, too. If it is haz mat, have a haz mat crew do their thing. Live long and prosper.... blah blah. Once in a while we need to hire certain jobs out, and this sounds like it may be one. GL. john

Troubled Basement Walls - Mold


Thanks for the reply guys. I'm not trying to hide anything; I just don't have the finances to do any of this professionally. Some friends of mine have recommended a few different options, and would like some opinions on them:

1. A friend said that I could cover all walls with plastic, then stud them out on top of the plastic. This would keep everything air tight.

2. A friend recommended buying surface bonding cement and covering all entire walls with this product.

What do you all think about either of these solutions?

Thank you so much!

First, why are you getting mold? Water from inside, or out? If it is from the outside, plastic on the inside will exacerbate the problem by preventing any drying to the inside. I would never put a vapor barrier against concrete; you can not make it perfect everywhere, vapor will sneak in, and you are back to square one, but worse. If it were mine, I'd get rid of the mold and lead paint and try to figure out why the mold was there, then prevent it from recurring. That may mean digging around the foundation, cleaning the walls, and sealing them. I'm afraid there won't be a simple, easy solution; either lots of work, or money.

Troubled Basement Walls - Mold


The mold is only growing on the paint that's in the mortar.

I have killed all of the mold and repaired the ground around my house to slope away from the house.

Since the walls are painted with lead paint, I would really like to be able to cover them. I have a small budget, as I have a low income. I can't afford to have the lead professionally removed or anything.

In order to cover up the lead paint, and suffocate it to prevent any more mold from forming, is it possible to do the following?

  • Is there any sort of spray concrete that I could spray on the walls, then paint something like Zinsser or RadonSeal over the new concrete?
  • Or is there some sort of spray polyurethane or anything like that?
Thank you all very much for your help and support. I look forward to hearing a response.
