Having previously fitted 6mm ply (external ply from memory) soffits on my workshop they are now all covered with black mould over the winter. The soffits were painted originally with one coat of barn paint before installing. What’s the best method of repainting these? Would I have to paint them with an anti-mould wood paint before painting with a coat of barn paint? If possible I would like to this repair to the soffits insitu.
Would appreciate anyone’s assistance please. Many thanks.
