[p1w1]

Hi,
Quick question, Have just bought some non caustic tfr for a cons roof what is a good ratio to use I have bought 3.5 litres concentrate and that is to make up about 25 ltr's diluted which i think is still a bit strong, i think i saw on here somewhere around 20 -1 does that sound about right.

thanks
Paul

if you put it through a pressure washer it will dilute it 16:1

thanks steve

I was just going to make a small mix and spray it on so i reckon 20-1 will do
