How to Make Medieval Stone Walls out of foam


This is a tutorial showing you how to make great looking stone and brick walls with sheets of foam. There are a lot of different uses for something like this. I am currently building a room that is very medieval and I wanted some stone work so we figured out this nice process for doing it.

In this tutorial I show you everything from start to finish.

I also have a video tutorial for this project at the bottom of this page.

Home Depot has the foam I use in a variety of sizes

Here are two pictures of the stone wall we make in this tutorial. The first picture is a closeup so you can get a good feel for how it looks finished. The second picture is a bit away so you can get a sense of the size and scale of it.

Size: The wall we make is three feet wide and four feet tall. But there is absolutely no limit to how large you can make it. This is all modular, the pieces go together seamlessly.

Materials and tools for this project:


I have a drawing of a sample stone pattern for you. It is an image the size of a sheet of paper so you can download it and print it up. It will give you a look at how to arrange your stone pattern. Sample stone pattern is here.





I am using something called foamular. It comes in various sizes and thicknesses. The size I use is one inch thick, two feet wide and eight feet long.









This foam has a system of interlocks so you can piece it together seamlessly in any size wall you need.








The first thing you do is cut the foam to the desired size you want. We are making a wall that is three feet wide and four feet tall. Be sure that you line it all up so the interlocks fit together. Here is our finished size.






Use a yardstick or ruler and a marker to mark out your brick pattern.









If you have multiple sheets put them together so you can continue the stone pattern seamlessly.









The yellow line shows the seam between the two sheets of foam. And you can see how we just continue the pattern.
