Mark J Posted June 10, 2022 Report Share Posted June 10, 2022 I have used acrylic paint just a couple of times now and have been wondering about overcoating it with either a hard wax oil product (like Osmo Polyx-Oil) or a polyurethane varnish. Has anyone ever tried this? If so how and what did you apply? How did it work out? I guess I can try it on scrap wood easy enough, but curious about the experience of others.

wtnhighlander Posted June 10, 2022 Report Share Posted June 10, 2022 I used GF High Performance over GF 'Milk Paint', which is actually acrylic, with very nice results. Applied with a foam brush. 1 1 Quote Link to comment Share on other sites More sharing options...

Chestnut Posted June 13, 2022 Report Share Posted June 13, 2022 I'm not sure how the hard wax oils like Osmo would work that'd be an interesting experiment. I've applied water borne poly over acrylic paint all the time it works great. Quote Link to comment Share on other sites More sharing options...
Mark J Posted June 13, 2022 Author Report Share Posted June 13, 2022 Here's my scrap test piece. The acrylic paint was allowed to dry overnight. Gel poly on the left and Osmo polyx-oil on the right, with nothing in the middle. Single coats on unprepared maple. The paint is a titch darker and maybe a titch yellow under both coatings, but it would be hard to tell if all the paint was coated. There was the faintest blue "stain" on the buff cloth, but the cured paint was not materially affected by the solvents. Not sure if I'll go this route, but it's nice to know your options. 1 Quote Link to comment Share on other sites More sharing options...
