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?

Oil and water don't mix. You could try a good wash over with sugar
soap and then have another go?


I used oil based primer then water based gloss and there was no problem,
but there was a delay of three weeks between primer and gloss.

Yes, all these water paints say they are suitable for previously painted
surfaces. Maybe I need to prime the undercoat, mad as it sounds.
