If I paint over a higher VOC paint, with a NON-VOC paint, will it cover the VOCs
I have a question about no/low VOC paint. I've recently purchased an Interior Acrylic Latex paint with under 200 VOCs and I have heard that paints give off VOC's well into a few years later, after applying. I bought the wrong type of paint and I wanted a paint with no VOC. So my question to everyone was that if I used that paint with the higher VOC volume, and then I painted over it with the VOC free paint, will the VOCs from the first type of paint be safely hidden and covered from the VOC-FREE paint?

Welcome to the forums!
Personally I think all the talk of VOC and non VOC paints is overblown. For the most part, fresh air ventilation for a few days after painting will remove the majority of VOCs. There is a minority of people that have adverse effects from VOCs so for them it is a concern.
I suppose a fresh coat of no VOC paint over regular paint will stop most if not all of the outgassing from the 1st paint but the majority of the VOCs were released while the 1st paint was applied and drying.
I'm a painter not a chemist so take what I've said with a grain of salt

after the curing process (at most 3wks) all the VOCs are gone. About90-95% are gone once the paint has dried for a few hours. If you do not wait for the first film to dry before putting on the second one, VOCs will probably be the least of your problems.
