Over the last 20 years we've had several attempts at a lasting paint job on an ex-shopfront and door. We've got a mixture of hard and softwood, and have replaced some horizontal sills over the years with new wood. It is south-facing and receives full doses of rain and sun (except the door which is under cover).
Earlier this summer we used Farrow and Ball oil-based exterior gloss (special mix, National Trust colour), their undercoat and their aluminium primer. We received frequent advice from their technical dept. to get the products and procedure correct. Results are basically an expensive disaster.
First problem (6 weeks ago) was the final coat wrinkling in several patches, mainly on the sills. F & B's opinion was the paint had been applied too generously - unlikely, but possible.
Current problem, 6 weeks on, is that primer/undercoat/top coat have all lifted off the knotting (Blanchard's), all three coats have cracked badly at the join of horizontal and vertical parts of the sills and window uprights and also on the horizontal sections of the sills.
I am finding my original customer advice guy at F & B slightly elusive, though summer hols. may be a perfectly understandable factor at their end.
No problems with Dulux or Albany over Blanchard's in the past.
Would anyone have any comments or advice?
Many thanks.
