"5 litres of say Protect Nano will do up to 400sq m when diluted.
That's £52.80 in materials...let's say £70 just for good measure.
So £70 plus what you want...presume you'll inflate the price of materials for them a bit.
How long to spray down the stuff over 380sq m??
90 minutes on the topside so decide what you want for it. "
Seems a large area for 5 ltr
not that i have ever used the product ,
I went in with price of £700 seems i shall have to reduce the price although they have accepted this
i was along the lines of Garys figures
