High pressure hot, twin set up. 2 of us on it for 5 hours.
Paving stones were easy the block paving was a pain clay block really old as we were cleaning it seemed more was appearing.
I think because it was a first using the set up.
It was a lot quicker than the low pressure steam I borrowed of you Trevor that was an experience not to be repeated.
Any way did 3/4 of the job back next week to finish then might get paid!
