    pre treating concrete

    Hey all....question on what is common practice on surface cleaning .driveways/sidewalks. Instead of downwashing with use of a machine can i use a mixture of 12% pool shock and water via a hand pump sprayer? if so at what mixture 50/50? Also should if finished with an undiluted light final coat of the pool shock? I am just getting started and am using a MiTm 3500 pressure washers and 24" Hotsy Surface cleaner.

    I’m 55, been in this business for 25+ years. Climbing ladders hurts a little more than it used to but I’m still rolling along. Busy most days of the week.

    I don’t pretreat if it’s just dirt or mold. oxalic acid can help remove rust stains around pool aprons. Putting pool shock (SH) will instantly kill any vegation it touches and will destroy the O-Rings in the pump sprayer unless they’re Viton seals. A light acid coat when the concrete has dried from the washing will brighten it, makes it look nice Let us know how it turns out.
