Can You Mix Enamel And Acrylic Paint. Enamel paints can also be used on many surfaces such as plastic, metal, glass and wood. Can you mix paints that have different thicknesses?
This is a good question because i am sure there are many. Water soluble, but becomes water resistant when dry. In some cases if you mix a certain type of oil paint with acrylic it can melt the plastic of your model like gasoline melting styrofoam.
The paints becomes gummy unworkable so you must have some barrier separating the two.
In most cases, both paints will have a different chemical formula and solvent making them incompatible. If the clean up instructions on the enamel indicate you need turpentine or mineral spirits (paint thinner) to clean brushes, they won't mix. If it's mineral spirits you'll be fine.lacquer thinner however may soften the acrylic if the concentration is too high.
The acrylic paint for walls simply are thicker with more teeny acrylic beads that bind together when the water evaporates.
I have tried mixing enamel with acrylic and oil with acrylic and i get very bad results. There are latex paints that come in an enamel finish. If the latex paint is oil based then it can not be mixed.
Bond failure is usually the result of doing so.
If you prepare the surface properly, acrylic paint can be used over enamel paint. This is because the sheen of enamel paint interferes with the acrylic paint’s color. Sanding the substrate to provide a mechanical “tooth” to facilitate bond works well them application of a primer to enhance the chemical compatibility and bond can work.
If the enamel is also latex than you can. You can mix heavy body acrylics with fluid acrylics without any problems, although it will obviously affect the thickness of the paint. Enamel is usually an oil base paint.
Also it depends on how you intend to apply the overcoat.
If they say clean up with mineral spirits, then you have an oil based paint, and no, you can't mix this type of paint with acrylics. Generally speaking, it's normally ok to apply acrylics over enamels, given that the latter are fully cured. What happens when you mix acrylic paint with latex paint?
