Jeff Downstreamed the 12 percent.Yoo Hoo......Where is Chris Tucker on this subject?? Is Jeff correct on the straight 12%?? How bout a rinse?
Jeff Downstreamed the 12 percent.
If using a chemical pump, 50 percent 12 percent chemical to water ratio should do nicely.
We suggest NOT adding TSP or anything to the chemical/water mix on Slate Roofs.
I have had TSP solutions actually cloud up a Slate Roof we once did.
It looked like crap until several rains.
Any roof will look better right away with a good rinse.
Again, suggest rinsing with only water.
Detergents/Surfactants can cloud Slate roofs, why take a chance ?
Thanks man.Nice website too.So you want to share the additive with a guy that's a thousand miles away?I promise I won't try to come to Tampa.
