Yes, you can. The resin systems for General Finishes Exterior 450 Topcoat and Milk Paint are the same.
General Finishes Milk Paint is a premium low VOC, self-sealing interior/exterior mineral-based paint named for its low-luster sheen. So durable, it is a go-to finish for cabinets and furniture.
Vinyl or paper veneers can be often found on the end returns of lower price-point cabinets. We cannot guarantee that our paints will adhere well to a paper veneer - we have no idea what the actual material is or what adhesives were used to apply the veneer to the surface. The resins and additives in our paints may break down the adhesives used for the veneer.
And Milk Paint does NOT adhere to vinyl.
Should I use a topcoat or a wax over my paint or stain finish?
The GF gang gets this question all the time.
We're very honored to be a recipient of Woodcraft's "Innovations Award" for our water-based and oil-based finishes!
