Thread: First brick wash job, heavy black mold

  1. #11
    Not bad for a 42 year old walkway. Mark, as with a lot of the folks here, I have multiple types of pumps in my trailer. I do a lot of walkways with retaining walls like the one I have shown. I also do a lot of retaining walls which have vegetation above and below the surface to be cleaned.

    I used my small AODD pump for the walkway shown. If you don't already have a AODD pump setup, give it a little thought. They offer the flexibility of applying your mix as fine as a trigger spray bottle all the way up to full flow as if using a garden hose.

    Runoff control is superb with an AODD pump setup. Yes, I have 12v pumps however, once you go with air, you won't want to go back!!!

    From all of us, you are welcome. It's why we are here, to share information...

    Thanks again for all who gave me advice on this job. I completed the job today and the home owner was very happy with the results, so was I. Sprayed a strong mix of 60% SH and 40% water on the brick with my roof machine and watched the black mold pretty much disappear after a few mins. Then rinsed off with my downstream fan tip. Wish I hadn't forgotten to take after pics of the house and patio...doh!! At least he is only 15 mins from me

    Pump up sprayer. 12% SH diluted 1:1 and soap will do just fine. Rinse at 700 psi. Easy peasy.

    If you don't mind me asking what does AODD stand for?
