Just completed 2 coats of the liquid DPM today.  I did the first coat yesterday which took ages.  Two reasons for this.  Firstly, I could see every single missed area and hole and thus I spent a longer time on each section and secondly the brush I used had too finer bristles and was a bit chunky (depth of brush).  For the second coat I used a wallpaper paste brush which had much coarser bristles and was a bit wider.  The bristle depth was also a lot less.  The LDPM just went on so much easier with this brush without clogging up the bristles and it cleaned up so much better.  Anyway, you live and learn but the it does mean I'll easily complete the third and final coat in a couple of evenings this week.
