Overcoating Dulux Weather shield Oil Based

[DaddyZord]

I have been asked to overpaint some external oil based Weathershield painted doors in the same or a very similar colour.

Customer doesn't want any strong smells and the the stress of the doors left open for hours due to amongst other reasons being heavily pregnant. Bar a reasonable sized crack in one of the panels the existing paint is even, sound and is well weathered.

What are my options here?

I've had a look at a colour matched zinsser allcoat which looks like it negates the need for an adhesion primer however a bit concerned about it drying too quick in this heat and getting a half decent finish.

I have also looked at the dulux weather shield quick dry however I'm assuming I would then need an adhesion primer to bond with the old oil based surface ( which I am also guessing I'd have to colour match to the door colour if this is possible ?).

Can anyone nudge me in the right direction with this?

Sand.
Clean.
Use a pre paint cleaner. Zinsser make one.

Uni-Pro High Tech Micro-Fibre 6.5" 4mm Nap are very good.

Paint early. Above 25c heat its a problem but 30c is the cutoff. Just got to work with the weather.
I would use allcoat.

Thanks Wayners. Good to know I'm on roughly the right track and thanks for the roller recommendation!

I did forget to mention I wasn't sure whether to use the water based or solvent based Allcoat. Do you ( or anyone else ) have a preference here?

Also not sure whether the satin or gloss would be best?

I'm after the best overall finish if that makes sense? As in is it worth sacrificing a bit of sheen for a more solid colour or less obvious brush marks.

I've used the allcoat waterbased satin white on the porch at my house and it was easy to apply and looks good however wasn't the most opaque white I have come across and its all window frames rather than a big block like a door so hard to guage if it cuts the mustard in terms of finish.!

Waterbased because of the solvent smell.

If you think it needs it use coverstain. Give it 4 days ( spec says 7) then waterbased allcoat
