Resin castings for Painting
cast some of my products in urethane resin, because it is durable, lightweight
Some products like my bases are made in a spin cast process similar
to that used to cast metal miniatures. I have this done because it allows
for speed of production and makes hopefully an affordable product. In
the casting process a "paint able" mold release is used to
allow you to paint them more easy. One of the slight side effects of
this process is some smooth surfaces may end up being very slick. Below
I will give tips on how to clean up your casting and prepare them for
parts from packaging
any flash, mold lines or gates with a hobby knife,hobby file
and sandpaper. I like to use sanding sticks to clean up the
A sanding stick is either a pre made stick with abrasive sheet
glued to it or in my case I make my own by gluing sandpaper
to a flat stick like a piece of styrene plastic or popsicle/craft
stick sold in many hobby shops. In my opinion they last longer,
are cheap to make and work well to clean up things like this.
- I recommend
all flat surfaces like the bottoms and edges of my bases to
be lightly sanded with a 220-320 grit sandpaper to remove any
mold lines and add a slight tooth to the resin surface. This
will help paint adhere.
- I clean
all my resin parts and bases with a mild powdered kitchen cleaner
like Comet, Ajax, Bar Keepers Friend or any of the cleaners
sold for cleaning the kitchen, scrubbing pots and pans with
a old toothbrush and rinse them well in warm water.
This helps remove any mold release and all etches and adds a
slight tooth to the resin surface to allow primer to stick better.

figures to them. I use a 1/32 diameter brass rod/wire and drill
into the feet and into the base and glue with a good CA glue.
Sometimes I will pre-drill everything and glue the figure to
the base once painting is done.
the most IMPORTANT part is to apply a good primer to the resin
parts before painting with acrylic hobby paints. I use a good
primer like Krylon spray primer or primer made by companies
like Games Workshop. Automotive spray primer is good for this.
Many primers are available in dark gray or black.
Allow the primer to dry a good 24 hours before painting. Yes
you can paint in 30 minutes but in my opinion allowing the primer
to dry longer increases its strength and durability.
- Paint with
your favorite brand of hobby paints.
I hope this
helps you with painting your resin product you bought from me.
