Halloween Mausoleum From Styrofoam





Introduction: Halloween Mausoleum From Styrofoam

This is a prop built for my daughters haunted house at her school. We used styrofoam to create the mausoleum.

Step 1: Materials & Tools


2 x 8 Blue Styrofoam for side pillars
4 x 8 Styrofoam for Capstone
Latex Paint
Black Acrylic Craft Paint
Foam Adhesive
Decorative Moulding


Dremel Tool with Router Attachment
Hot Wire Foam Cutter

Step 2: Cut Styrofoam

I cut the blue foam into two pieces measuring 6 feet by 1 feet wide each. i cut another piece out of white styrofoam to make a triangular capstone. I prefer working with the blue styrofoam. It is easier to cut and shape and stronger overall than the white stuff.

Step 3: Routing

Using the Dremel tool with router attachment, we made a channel along the edges of the styrofoam pieces. I also cut out two alcoves and backed them with leftover pieces from the capstone.

Step 4: Weathering

Each piece was sprayed with spray paint. The spray paint melts the styrofoam and creates texture. I used the hot wire foam cutter to make the crack in the capstone. I used sandpaper to roughen up the edges and the channels.

Step 5: Painting

I painted the pieces with offwhite latex paint. While it was still wet i painted the routed channels with the black craft paint. The black paint was watered down to help it look more like a stain. I let it dry and then painted it with a gray latex paint. While this was wet i used the watered down black paint as a wash to antique it more. Then i added the wood moulding to simulate a decorative element.

Step 6: Final Look

Here is the final mausoleum with battery operated lights in the niches. We added spanish moss to the mausoleum later. We also added the foamcore gate that we had from an earlier project.

Step 7: Attached to Our Door

After the carnival we added it to our front porch decorations.

    You have given me my NEXT Halloween decoration project! I am in to Halloween big time and I LOVE to decorate! What an awesome idea! I have never done antiquing but I am sure there is a video out there to tell how! LOL Thank you for the inspiration!

    Nice work! Do they survive from year to year? I'm always afraid I'll put a lot of work into it and they'll be ruined by the following year. Guess I need to be a little more lady like when it comes to putting the props away!! LOL!

    This is awesome!
    How did you hang it on your door/front porch?

    Great work. We also do a Haunted House each year. Last year had 450-500 trick or treaters come through. It's all outdoors wrapped around trees and such. We've always used a wooden Mausoleum front which we had to retire last year. This new much lighter weight version could be just what we need. One question - how did you attach to your door frame?

    This looks like a great project to distract me from my midterms! Great work!

    Awesome! Just happened to find this. Great job. Mind if I borrow this idea? my kids would love this in the house this halloween.
