Im repainting an old brass caboose and I airbrushed the base layer with a Floquil oil based coat and let it dry completely. Id like to airbrush the next layer with a polly scale water based paint.
Does anyone know if the paint will properly adhere? I know that mixing oil based and water based paints can sometimes be problematic in large projects, but ive never tried on a smaller scale.
I’m only doing this because I cant find the right Floquil paint since they discontinued their line. Thanks for your help
Yes You can…but it must be cured, not only dry…usually 72 hrs. is a safe time. Some things to remember:
When working with a variety of paints remember you can paint an enamel or a lacquer over an acrylic.
If you want to paint an acrylic over an enamel or lacquer you may get cracking, unless you allow the enamel or lacquer to chemically cure completely. Sand any high gloss finish before applying acrylic paint.
Painting an enamel over a lacquer can be tricky due to paint and solvent formulations. Test the combination first before applying to a treasured miniature.
Also a Handy chart for You to save for finding Floquil colors to other Enamels, Acrylic brands of paint:
As Frank notes, once the first paint has cured, airbrushing a different type of paint over it shouldn’t be a problem. That goes for lacquer-based over acrylics or vice -versa, but lacquer-based paint brush-applied over water based paints may cause problems, just as brushing lacquer onto plastic may cause crazing of the plastic while airbrushing the same usually works just fine.
Yesterday, I airbrushed these doors and windows with Floquil Grey Primer. In a couple of days, they’ll get airbrushed with the final colour using Pollyscale:
Once the brick portions of the structure have been painted (airbrushed Floquil), they’ll be masked-off and the concrete parts will get an airbrushed application of Floquil primer in preparation for a concrete colour, mixed using Pollyscale:
