As you may have noticed, my dice tower (and most of my buildings so far) are constructed mostly of packing foam (Styrofoam). As you can see in this picture, the foam bubbles and small holes in Styrofoam is not really a desired look for model building, so I have gone on a quest to find the best way to hide the Styrofoam texture. Here’s a picture of my Dice Tower Wall after I painted the Styrofoam, and before I filled in the Styrofoam holes:

If you put 3-5 coats of acrylic paint on Styrofoam, it will eventually cover up these holes. Another tactic I’ve used is to spread Elmer’s Glue or PVA Glue (White Glue) over the surface of your building. Or you can mix in the previously mentioned white glue into the paint before painting the Styrofoam or foam. All of these create a very smooth and flat surface on your foam, which is nice but not realistic.
I happened to have a small tub of “light-weight” Spackle hanging out in my closet, so I spread it over the surface of my building. In this next picture you can see how the Spackle automatically filled in the Foam holes, surrounded the Styrofoam bubbles and filled in the cracks. I accidentally painted this building black before putting on the Spackle, but in the end has helped a lot for these pictures.
This next picture shows the thin layer of Spackle I spread on this foam dice tower building. I tried my best to thin out the Spackle and create a nice, smooth surface over the foam. In retrospect, I would definitely recommend a thicker layer of Spackle. The extra Spackle will add more texture to your building and cover the foam better.
As you can see in this final picture, the layer of Spackle is too thin and shows some of the foam bumbles. I’ll be adding another layer of Spackle for texture and to cover the Styrofoam bubbles.
I’ll be putting together a Tutorial for Covering Styrofoam and Foam in the next couple days!
