Question about Concrete Barrel Tiles: What mix concentrate?
I am concerned about the black stains turning brown and needing pressure. I have done tests before on precast concrete and I needed a little pressure to rinse or a brush to remove staining completely. Concrete is very porous and SH will not clean alone. Thoughts?
I remember AC posting about a pre-treatment of green wash before the a a standard mix is applied...
If its just turning brown and needs pressure , then your mix is not strong enough...Ammmmmm MIXOLOGY! Am i the one of the very few how had to pay for this information...Come on...Its all in the modules..
