Oil paint over acrylic primer?

[anonymous-user]

Externally is this OK?

yes should be if the timber was prepared properly before priming and don't believe the cr*p about self knotting especially if it was a cheap type brand of primer.

Thanks for that - I've scoured the Dulux/Crown data and specs and there's no info at all. You have to dig deep to find if some paints are even water or oil based and as for what can go onto what it's non existent! Not water onto oil is an old no-no but the other way round I wasn't too sure about. The paint manufacturers really need to get a handle on it and make it simple or there'll be some disasters.
I've primed up and glazed new wood windows so I'll start to coat them up tomorrow

I've knotted skirtings with a bit of emulsion that seems to work fine!

Or you could just check if it says the brushes can be cleaned in water, if so its water based

Yes that what I was doing, trying to relate top coat solvent with primer solvent to find a water primer with recommended oil top coat, or oil primer with water top.
Websites no info, literature no info, and tins very confusing as I mentioned earlier.
Earlier yesterday I emailed Dulux on the email on the website but got a reply saying the email address was an interior design company and they can't answer the question ! I suspect 'amazingspacedesign.co.uk' aren't actually Dulux.

It seems to me Dulux need a bit of sort out if seems a right mess

Water based primer under oil paint is ok, but you may find the longevity somewhat lacking externally.

Since ICI sold Dulux to Akzo Nobel the quality of the paint, technical, and stores has gone downhill.

Thanks for that. I thought Akzo Nobel were streets ahead of Dulux. The Rubbol DSA onto Onol Primer was THE top microporous paint - brilliant stuff. I wonder if it's all gone pear shaped then.

Dulux have confirmed solvent OK on water primer. They weren't aware the tins have no indication at all what to use on what and no guidelines or spec - they said they would flag it up to be amended.
In fact the water top coats have no warning not to use on oil primers, and you have to look at the brush washing instructions to have a fighting chance to know if the paint is oil/water based - how does Joe Public stand a chance??
Incredible.
They seem to be keen to punt out paint with brochures all about fancy interiors with many pages wasted on crap photos with fk all about the detail.
