    Clarification

    Hello everyone,

    Thank you in advance for your help. I've been doing tons of research before I start a residential project. I'd eventually like to do roofs as well. I'm a part-timer for now. Small homeowner rig till I can afford another. 2800 psi, 2.3gmp (LOL).

    Just want to clarify my house mix and get a better understanding. Seems like the standard house mix is 2 gallons SH (I'm using 10%), 3 gallon H2O, 5 oz Elemonator (simple cherry as an alternative), maybe a dash of dawn or gain. I have a 10:1 general pump downstream injector. Are these calculations correct? If so, then I only have .4% SH hitting the surface??? Here is the calculation:

    2 gallons in 5 gallon pail = 40% solution in the 5 gallon bucket X 10% pool bleach solution= 4% actual SH / 10 for the injector =.4% hitting house

    It would take full strength at 10:1 to get 1%, correct?

    I have read here and on other forums that you need at least1% SH to kill mold on siding. (2%-3% if you want to go faster) and 3-5% on asphalt shingles.

    Any comments on my calculation and question?

    Thanks,

    Calculations are irrelevant. Don't put dawn in your mix. Use the mix you have. I'd or doesn't kill mildew in about 2 minutes. Make it stronger

    This time of year, err on the side of caution and do like William says.. I think the heavier side of the mixes you propose are where you will end up, but learning by experimentation is how you have to go.

    I just had a tiny flashback.

    My two heroes from when I started ten years ago, The Fennerator and The Redneck General, gathered on my friend Bob's site. I think I even saw a post from Dave Mac a minute ago.

    This is my mix I use if u want something to work off of. This is house wash mix, not roof mix. Roofs are a division I havenít broken into yet:

    Downstream mix:
    2 gal of 10or12% SH
    3 gal water
    5 oz Elemonator
    1 tbs of Gain original

    X Jet mix with 10-1 proportioner:
    1 gal of 10or12% SH
    4 gal water
    5 oz Elemonator
    1 tbs of Gain original

    On extreme hot full sun days I cut my SH back by about a 1/4 to 1/2 gal.

    Correction: with my units 5.5 gpm, my Xjet is about a 7-1 proportioner.

    Calculations are a good text book way of mixing, but with the way SH degrades with time you can throw the text book out the window.
