well just did the first coat of pva. amazing how many bits of grit the
roller picks up even after i'd hoovered it. well hopefully this first
coat (diluted 5 to 1) will seal most of it then i'll do another coat
maybe a bit thicker to finish off.

wait for that to dry then have a go with levelling compound. what type
of trowel do i need to do a basic levelling (after all its meant to
level itself?)?
