why is it that one wouldnt downstream sh onto the roof with a pressure washer? would the higher dilution ratio of bleach coming into the injector and through the hoses and gun cause damage?
Tim, I think you mean sodium hypochlorite. The solution wouldn’t be strong enough and you would have a lot of overspray.
You need 3-4% sh to clean a roof. If your downstream injector is 10:1 the strongest solution you can get on the roof is 1.2%.
I did mean sodium hypochlorite, I used chrome autofill. My bad
Thanks for the info
Hello everyone. Just downstreamed Sodium hydroxide on a roof last week called Supper Roof Bright. Worked well but had to rinse with mild pressure. I have finally come to the conclusion that bleach with additive is truly the best for almost everything. Took a long time. Time for a big chem pump and a tank. Looking for the holy grail of no rinse with no worry. Thanks to all for your knowlage and openness.
Do you have a link to that product?
Hey Chris. I think my local dealer gets theirs from aok.org/ SPRproductsales.com. The only other dounstreamable sodium hydroxide I’ve found is powersolve at the sealer strore. Hope this helps.
Hydroxide dissolves and eats oil…shingles are asphalt. That is a bad combination.
