This tutorial will show you how I make simple rubble bases. The intent is to create something that looks like broken concrete or stone slab. Other than the base, there are three things you will need to create this base:
For the rubble bases, I start with a 12″x12″ vinyl floor tile that I found at Home Depot for 70 cents. You can also get them at Lowe’s and probably many other hardware stores.
This is not an adhesive backed tile, both side look the same as the one shown. It is soft enough that you can break it up with your hands or a pair of pliers.
You can see that it breaks with nice, uneven edges that look similar to broken concrete slab.
Then I attach a couple of pieces to the base using super glue. Sometimes I will line them up so that it looks like a large crack running through a crumbling slab. Sometimes I set pieces at angles or on their sides to represent pieces that have moved around more. You can also put something under one end of a larger piece so that it sits at an angle for a nice, dramatic pose.
After the glue has dried, I fill in the gaps with some pre-mixed grout. I am using a tub that I found in the garage when I was moving into my current house. The previous owner had done some grout repair in the shower before putting it up for sale. If you don’t feel like buying random houses in hopes of finding leftover grout, you should be able to buy it in pretty much any hardware store for around $10. Look for pre-mixed, sanded grout.
I used a sculpting tool to place and form the grout, but your finger or a popsicle stick could work as well. The grout fills gaps much better than sand and can be built up. You could achieve a similar effect by mixing sand a glue into a paste, but it’s much easier to just take it straight from a tube and get to work!
The grout has a nice, sandy texture for rubble bases that paints up nicely.
After the grout had dried, I primed this base black and painted it with a darker then lighter shade of brown. Then I picked out the slab with a lighter tan.
After that I gave it a simple wash with brown to bring out the texture a little more.
This is enough to give you interesting rubble bases and help your models stand out a bit more. It’s also easy enough that you can crank out a lot of them without killing yourself.
If you want it to look like it’s been sitting around for a while, you can add some flock or static grass to represent plant life starting to take hold in the cracks.
For a little more variety for your rubble bases you can add other bits and use the grout to make them appear partially submerged in the rubble. For the sentinels shown below, I added some larger gravel pieces and bits before putting on the grout.
This is a simple but effective way to add more character to your models, and it’s just one of many techniques you can employ. What’s your favorite basing technique?
