When I first started using water based paints it wasn’t because I wanted to go eco friendly, it was because I hated oil paint and wanted to try something different.
There is definitely a market for earth freindly paints now though with a lot of customers now specifically asking for them.
A lot of UK painters just don’t want to know though, prefering to stay with oil paints for trim. Not saying they’re wrong, but I wouldn’t use them anymore. To much hassle with drying times and yellowing for me with the new formulations.
I am still sceptical about the reformulation of oil paints because the way I see it is I’ll still put more pollution in the atmosphere driving 30 miles to work once than I will using 10 gallons of oil paint a year. But I suppose we have to start somewhere.
Mythic is the only true zero VOC paint I’ve used and I’d have to say everyone, myself included, has been very happy with the results. I also like Dulux Ecosure Gloss and Johnstone’s Acrylic Satin. I wouldn’t use any of them without a paint additive/conditioner to hand though. Floetrol is good, Zamix is better.
I always use an adhesion promoting primer with them though because if the paint doesn’t adhere you’re in for big problems. Mythic, Zinsser 123 and Joncryl are the ones I use the most. Mythic has by far the best opacity but if you’re on a budget the Joncryl does a fine job for not much money.
If I’m spraying the primer it would be Joncryl every time because it’s more economical.
