An ornamental garden gate in softwood. I gave it a few coats of
aluminium primer and best quality grey oil undercoat. Mrs W chose a
top coat of Farrow and Ball exterior gloss which to my surprise is
water based. Anyway it doesn't go on, won't film at all.

The undercoat is matt and was rubbed down a bit so advice to key the
surface better will be pointless. Is there a solution to this? or just
buy oil gloss?

How long was the undercoat let to dry/cure? Often the manufacture will
give a drying time or re-coat as 24 hours BUT at ambient temperatures of
20C. If painting at this time of year outside you would have to adjust
the times, especially for the night time temperatures.


It's in a unheated shed, but undercoated 4 days previous. you'd think it
would be fine, didn't clog the 180grit paper.
