I have returned to an 18th century cottage to “freshen up” some woodwork.
I was last here about five years ago when I carried out some pretty extensive decoration after years of neglect.
Five years on, most of the redecorated window frames are still in pretty good condition but nearly every sill and lower beading has failed
This despite days and days of extensive rubbing down severely weathered oak sills and taking the time to apply full coats of primer/undercoat & SuperOpaque top coat.
I am assuming that I have missed something at the prep stage with the oak sills…
In particular where I have two-packed sections on the sills, these have all delaminated
On weathered oak, would a shellac primer (BIN) achieve a better result that the Dulux Weathershield primer ? When I raised the issue with Dulux technical they said don’t use dark colours on sun facing elevations… Not quite the advice I was anticipating !!
Any suggestions welcome !
