There have been many webpages and probably a couple instructables on this subject, but this is my version with a couple hints that might help others with the same project.
Step 1: Materials and Tools
The Materials are-
- White Foam Board (found at Lowes in a 4 foot by 8 foot sheet in the insulation area)
- Liquid Nails or Loctite Powergrab (glue that won't dissolve the foam board)
- Spikes (found in hardware 8" Hot Galzanized Spike; 2 for each stone)
- 1/2 Pint Latex Primer (White or Gray)
- Stone Spray Paint
- Black Paint Pen
- Scissors, Tape, Pattern
- Spray Glue
- Small Piece of Plywood (For Base)
- Black Spray Paint
- Foam Brush
- Jigsaw, Bandsaw, Styrofoam Cutter, or other cutting tool
- Drill with drill bit (for the spikes)
- Spanish Moss
Step 2: Patterns
If you don't want to do this, or don't have the software, I have included some of the stones that I drew if you want to use them. If you don't want to use my drawings, then you could always print out a picture of the stone you like to whatever size you want and trace the outside. You could also draw it free hand onto the protective coating that the foam has.
A freeware program thats like Corel Draw is called Inkscape
Step 3: Cutting the Basic Shape
Use spray glue and attach the pattern onto the 1 or 2 inch thick foam board
After the pattern is attached. Take your cutting implement and start with the straight cuts first. Then do the curved cuts. I used a jigsaw to cut the foam board because it was the easiest for larger tombstones. Small tombstones were easier to do on my bandsaw.
Remove the protective film from both sides of your foam board.
*Tip: If you mess up cutting the shape, you can either keep it that way (Halloween is suppose to be creepy and it will look old) or you can use a file to fix your mistake.
Step 4: Rough Cut Stone
Using 1 light coast of latex primer (or no Primer) and a heavy coat of the stone spray will give the appearance/texture of rough-cut stone (The chemicals in the spray will lightly dissolve the foam)
Use 2 or more under coats of primer in order to maintain the original smooth foam texture.
Experiment using latex/spray finishes on scrap pieces of foam before trying it on your actual tombstone
I usually do one coat on the face and back of the tombstone and two coats on the sides because I don't want the sides to dissolve too much once I spray the stone paint.
Step 5: Base
Drill holes large enough for the spikes at the edge of the board.
I drive nails through the board where the stone will go in order to attach the stone.
Step 6: Finishing Touches
Some people use a Dremel, pencil torch, or wood burner and inscribe the epithet. If your doing this project in a hurry, then use the pen. If your doing these to look as real as possible, then use the dremel or pencil torch.
Attaching the base to the tombstone is the next step.
After driving the nails through the board, put a couple beads of Liquid Nails or other adhesive and force the stone down onto the nails and adhesive.
Optional: I put my adhesive all over the base board and then put spanish moss in front of and to the sides of the stone. It gives it a more aged look with the spanish moss around the base.
Step 7: Presentation
Throw some fresh dirt in front of the stone to show it as a freshly dug grave. Add some bones half buried too.
