I just pour a load in a bucket and add some water maybe a couple of pints.

I sometimes put my WFP brush in the solution and put on roof.

Or i use an applicator on a standard pole and apply.

Leave for 5 - 10 minutes then WFP off.

I dilute 20:1, spray on & leave 5 to 10 minutes before brushing off in the normal manner, this has always worked for me.

just started using regular tfr as opposed to safe or non caustic
done two roofs with it,one glass one plastic
cant see a lot of difference really
certainly didnt cause any damage
