Using Non Toxic Paint Over Toxic Primer

We have an old cottage home and the indoor paint may be oil based. I was told that we need a specific primer, before we can paint with the non-voc latex color we bought. That primer however is toxic, so I was wondering if you have an alternative suggestion?

Clear Skies Satin works well over oil based whenever possible. It has a bio based coalescent that helps it bond well to oils. However, not all oils are the same so a test area is recommended to insure compatibility.

Clear Skies usually works well, but we ran into a situation where someone painted a super toxic big box store paint. It was an oil based but had some silicone in it. Even other oil based coatings have a hard time adhering to things like that.  But NanoTech adhered well and we were able to block out the toxic odor.  If we need a safer stain blocking primer for water stains or tannin or such we use Mountain. 2-3 coats of Mountain has blocked pretty much any stain we’ve tried it on then we paint that with Clear Skies.

Best wishes,
