Introduction: Styrofoam Fake Faux Fun
***The double-negative is intentional because what I’m about to show you is both fake and real.***
I have to admit that when I started collecting Styrofoam packaging from products and empty Styrofoam coolers used for shipping temperature sensitive medications, I didn't know what I was going to do with it. I just couldn't see throwing this stuff away and it most probably ending up in some landfill somewhere..
Over this Summer, I tried a few ideas; I am making Halloween prop gravestones and fake rocks for an entire water feature.
Step 1: Parts and Tools
- Water-based ( or at least, water clean-up ) liquid glue Wood glues typically fall into this category but dries yellow white glues that dry clear - ish
- Elmer’s brand School Glue ( Water-based and surprisingly effective )
- Elmer’s brand All-Purpose (PVAc: Poly Vinyl Acetate based)
Spray Paint ~ Only AFTER you treat the Styrofoam to a coat of Elmer's!
- Dry mortar mix
- Sand, desired coarse and color
- Hot Glue Gun
- Paint Spray Gun and/or foam brushes
- Air Compressor, if spray gun.
- Foam Cutter ( Optional)
Step 2: Prepare the Styrofoam
- Hot glue works well, but keep in mind that the glue can get very hot, melt the Styrofoam and burn your fingers and hands.
- Break or use a foam cutter to shape the Styrofoam.
Step 3: Build Up the Desired Effect
- Build up the desired effect
Step 4: Spray and Dust
- Spray a 50/50 Elmer's Glue All / Tap Water mixture on the form.
- Toss and throw mortar mix or sand onto the form.
Repeat this process as needed to get the desired effect. The fountain has been built-up about 5 more times!
Step 5: Another Form to Hide the Water Pump
- Another form to hide the water pump
- Gravestone for Halloween

That looks so realistic! I must give it a try. BTW, PVA=Poly Vinyl Acetate.

That turned out great! Do you know if it can withstand rain and wind?

Great question! I was trying to decide how to share my experience using the Elmer's Glue-All and mortar mix makes an impressively hard shell! My concern has been that the hardened material would flake-off, but it adheres very well to the Styrofoam. I do live in the Pacific NW, so it's already had rain testing ;-) The weather doesn't seem to bother the structure. Neither does impact, a few large dogs on chains decided to wrap around it while playing. I'm wanting a more natural look, but should their be any indication that the thing is falling apart... I planned ahead and purchased a few cans of that FlexSeal Clear but have not used it yet.
