Faux Fieldstone

4 Materials
1 Week

I wanted to add some more character to our living room, so I decided to add a little something special above the fireplace.

I created lifelike field stone for over my fireplace made from Styrofoam, spackling and paint. I was able to give depth to the stone by layering some of the stones with 2 layers of Styrofoam. All were painted individually and sealed for a washable surface. Hope you enjoy this mini upgrade!

I started by cutting various shapes and sizes from the foam using a kitchen knife and an exacto knife.

Here are some of the different shapes and sizes cut to resemble real fieldstone. Next the edges were trimmed to round out the stones.

Here's the1st layer of stone affixed to wall using constructive adhesive. Then I put a second layer on various stones to give more depth.

After that, I applied spackling to all of the stones to give them a stony finish.

Here's a picture to show the depth I created by layering on various stones.

Here's the wall in the process of painting the stones.

Lastly, I finished painting and sealing the stones. Do not use spray sealer as it will destroy the Styrofoam.

This update has given such a warm feeling to the living room. Everyone who has seen the stone work thinks it's real stone--it's amazing!

I hope you love this, and maybe give it a try yourself!

    What is your wall type, sheet rock or something else? What type construction adhesive used.

    You said you painted and sealed the "stones". Then you said not to use spray sealant. So, what DID you use to seal it?

    That is an excellent DIY....you did an amazing job. I think if I was to do that, I would have put a 2X2 inch board on each side and run the stone down beside the fireplace sides to the floor and straight up to the ceiling... either way, it looks fantastic..!

    This is beautiful…..but I’m thinking that if I would do this I’d take it to the ceiling and sides. Thank you for sharing…😊
