Agapanthus time again

Another day working on the new garden room, painting it with preservative again. Will be finished tomorrow, then we need to sort out paint colours.
I am finding both the varnish and the preservative difficult as they are totally clear, you can not see what you have already done. I have been painting planking so there are lines but I still went over places already done. Also the preservative especially is like water, very runny when used on walls and impossibly messy when doing the underside of the roof. Several mouth fulls and my glasses splattered. Maybe a mouth full of preservative will mean less visits to the dentist.
