I'm putting an insulated wooden floor in my garage. The current floor is concrete and I've just waterproofed the outer wall/slab joints with tanking slurry and will probably do the inner joints as well.
The joists are treated 47 x 75 timber and was wondering whether I can paint the underside and say 25mm up the sides with Blackjack instead of using the polythene sheeting as the DPM?
