In my previous house had white gloss everywhere .... and that meant on new
wood ..
knotting primer 2 coats undercoat top gloss coat

In current place not used gloss anywhere, all skirtings, architraves & doors
are stained ash .... now come on one job where I don't want to stain.

Just finished putting finish on Loft access hatch ... opening all nicely
lined in Ply, hatch out of ply stiffened with 3 x 1 frame ...

Fixed the architrave around opening today .. and have just given it all a
coat of white primer.

The intent was to put a coat of one of the one-coat white paints, but SWMBO
just asked a valid Q ... "can't we just use same pain we put on the
ceiling?"

Never used semi matt emulsion on wood ... is there any reason why it could
not be used ?
