Is my math correct?

10 gallons of 6 percent sh to 90 gal of water is .6 percent, nearly half of the 1 percent you think it is

Who the hell is using 6 % bleach? None of the professionals I know for sure.

No one. I’m just correcting your math

My math dosent need correcting. No one said anything about 6% bleach.

10 gallons of 12.5 percent to 90 gallons of water isnt 1 percent like you think it is either

Ok. Thanks.

Im not saying you methods don’t work, I’m just saying your figures were wrong

In a 50 gal roof mix when looking for a 4 percent ratio, you would need 16 gal sh to 34 gal water using 12.5 percent. Using 10 percent you’d be at 3.2. Nearly a full percent difference. You must not do roofs?

The stronger the target mix the more discrepancy between sh strengths

Haha. My business name is Diamond Roof Cleaning. Look it up on google williamstown nj.
I dont use 10% sh. I use 12.5% sh. I actually prefer to use a 3.5 % mix on roofs especially when its above 70 degrees. We usually do around 300- 400 roofs a yr.

That’s great. This is a power washing forum not a roofing forum.
