Wot chems would you put on might try to put some down cheekily I want to do a good job as its a good price and its in a little close all with identical drivesNope not properly butiwant to make kt will get alot of the surface **** off so will look better than it did before but if they don't want any chemicals put down you can only do so much.
Thanks very much smurfAfter I had pressure washed it first I would use hypo 15%-20% myself at 1-1 ratio. Let it dwell for about 15 mins then rise it off with a house or pw lance with a black nozzle.
And I think Ive read on here if it gets on shrubs it will kill them this custy loves his shrubs even offered to hold a board to protect them from sprayNo probs but I don't think you would get away with that one somehow as it stinks
Could you link that mate? not used any chems up until now but always nice to have something to add to the toolbox.After I had pressure washed it first I would use hypo 15%-20% myself at 1-1 ratio. Let it dwell for about 15 mins then rise it off with a house or pw lance with a black nozzle.
I did an large area a while back on a very posh place. Not once did I use a pressure washer as just used about 8 x 25ltr 15-20% hypo at 1-1 mix = 400 ltrs instead.
Lets just say it smelt very clean after I had finished /emoticons/biggrin.png
