I've done a couple of conservatories with wfp now, and I can't seem to get them up good. I always seem to leave lots of bits on the roof. Last one was quite bad, and what was very difficult with that one, that it was so shallow, so rinsing was a pain, had to get my ladder out as well, and clean it with the pole from the ladder, very difficult. There seems to be lots of junk coming out of the seals on either side, and no matter how much I rinse, it just doesn't seem to flow off.
I tilted the brush on the angle adaptor so it was almost facing me, so I could rinse it better, but didn't seem to work that well.
The first cons. I did was a bit steeper, but stuff kept coming out at the top where there were some black bristles or hairs or something, very strange, should of used hosepipe on that one first perhaps.
Any tips for these? Maybe blast them first with customers tap? Don't really want to finish it with the squeegee you know.
