Just bought a 25 ltr non caustic TFR but not sure how much to dilute it for use in a pump sprayer for con roofs :S
I've been using a caustic one till now and the mix would surely be different with non caustic?
the guy in the shop said 99 parts water to 1 part TFR but that cant be right can it?
anyone know the right amount to use?
Cheers
Denis
