Got Mold In Your Basement on Cinder Block? Here’s How To Get Rid of It

| Basement Mold Cleaning | August 11, 2010

We were receiving some questions from our readers on cleaning mold off cinder block basement walls. So I wanted to put together some feedback to answer your question.

Question About Mold On Cinder Block in Basement:

I think the wall is leaking water through cracks and now I see mold growing. Can I clean it up with bleach & water solution, let it dry and then paint the wall with waterproofing paint? Will that work?

Some Answers from Our Team in The Office:

I asked around in the office and got a few answers, but wanted to share what they shared.

Bleach and water solution, scrub vigoriously… then fill the cracks with a compound found at any hardware store… then paint the wall with a schelac, a white waterproofing sealer… WEAR A MASK, very nasty stuff… but better than living with dangerous mold spores!

But bleach is JUST AS TOXIC….. so…

Here is My Official Answer:

First if you have mold on cinder block in your basement, it’s alot better situation then having mold in your drywall.

What most mold professionals use to get rid of black mold and keep the mold from coming back is a 100% unique mold kit.

I am very happy with the Molderizer and Safe Shield kit presented at MyCleaningProducts.com. These 2 products have been used by mold professionals for years. Actually  the product was voted top mold remediation product for 2010 and 2011 by the IAQ.

Here is why I recommend Molderizer and Safe Shield.

Molderizer is non toxic and a green formula that concentrated. It actually kills the Mold DNA makeup to completely destroy the mold. You can get this with most other products.

Safe Shield is also non-toxic and this product will be a 2nd application, which kills mold… but more importantly encapsulates your surface to prevent any future mold amplification.

Definitely check out the 100% non-toxic mold kits.

  1. Bleach is only 3% and is not strong enough to kill mold-go to EPA website and look for mold remediation.

    If you wall is leaking you need to figure out why before you can figure out how. Hydrostatic pressure is usu. the culprit but not always. So check on the other side to see what is up. Then check back to tell what you found.

    If you just bleach and paint over chances are it will just come back. Only this time with water bubbles.

    Nah. Bleach dries mold out, but it doesn’t kill it.
    The best way to get rid of mold (at least mold that’s visible and doesn’t require demolition to get to) is to scrub it with soapy (very soapy) water.
    Of course, you’ll also want to make sure that the conditions allowing the mold to grow are carefully controlled. If the water is coming in through the foundation, you may want to consider some options for waterproofing the foundation or providing drainage for the area around it.
    Examples are digging down at the foundation and tarring it (for waterproofing) or digging a drain around your house to divert the water (perforated pipe and french drains–which consist of basically a shallow trench filled with gravel–are popular draining methods.
    To figure the best method, just go to your local home improvement store and ask someone knowledgeable. He’ll ask the right questions about your specific situation and be able to recommend a suitable solution.
    Good luck.
