Hypo mix ratio

[Johnny]

Hi I've got 2 jobs tomorrow ones a marble pathway and the other is a drive which has those blueish kind of bricks.

Going to pressure wash on both jobs and then apply hypo. How much hypo should I use.

I think as a general rule a 3% strength mix is what most use for this after all the debating on hear about hypo I expect I will be shot down for saying this make sure that you get it right most hypo will be either 10 or 15 % strength read the label carefully before using it make sure the surface is wet with water first then apply your mix and let it dwell for 20 -45 mins

if i could add to that,after the hypo is down brush it all in so the surfactant can do its job-it makes life a whole lot easier when rinsing
