I have both the 25/28mm and 15/18mm versions of Blue Moon's Dracula's Castle and am looking to detail them. I assume spray paint should be avoided, but am wondering whether it's better to use acrylics or enamels. Do shading techniques used on metal minis work on high density foam?
What's the best way to seal and protect such buildings once the detailing itself is done? Any advice or tips will be most welcome! Thanks! |

I would think acrylics. Enamels might be risky. I would test an underside first. I would spray a protective final coat using an acrylic spray depending on humidity in your locale. |

The safest this before painting foam is a good coat of Gesso. link This forms an acrylic barrier and provides a nice "tooth" for paint to hold onto. I have always just brushed it on. It does cover small surface details to so extent. But I have thinned it to help prevent this. There are many types of foam. I strongly suspect that a detailed cast item will be a urethane foam which is very stable to solvents. As you may know polystyrene foam (Styrofoam) will melt with a number of solvents. But urethane is very unlikely to do so. Good advice above. test the bottom with a drop of the thinner for the paint you want, or a quick squirt from a can. |

I have painted a number of Hudson and Allen foam buildings (which seems similar to the OG/Blue Moon, although I am not certain of that). I tested some spray paint on the bottom of the pieces and no problem (I used Testors) after three or so years. I also shaded them with washes (I used Didi's Magic Wash) and had no problems. I then sealed them with Winsor and Newton matte varnish and again no problem. I have also seen Modge Podge mixed with black paint as a sealer/primer on YuoTube (Black Magic Craft is the channel). |

>>high density foam? Sounds a bit generic. Are you talking about polyurethane?
That handles spray enamels well- unlike polystyrenes which melt.
First, know your product. And yes, refer to the MSDS/ manufacturer for recommendations.

I believe the Hudson and Allen buildings are high-density urethane foam -- not sure about the Old Glory buildings. |
