DIY Fake Stone Wall

Title:  How to make a Stone Facade out of Insulation Foam Board.

Materials:  

• 4 x 8 sheets of insulation foam board (Lowe’s or Home Depot) Make sure to get the kind that does NOT have the foil on the back.  They had to cut the original size into thirds just so it would fit in my car, but they were more than happy to do so.
• meter stick
• straight edge
• marker
• jigsaw
• knife
• spray paint (we used “stone” colors: grey, tan and black)
• hot glue gun
• glue gun sticks
• wooden column was made by our math class with 2x4’s, plywood and nails.  

Step One and Two:  Decide on the sizes of “stone” you want to cut.  We picked a variety of 18”, 12” and 6”.  Let’s take 12” to start as an example.  From the foam board, measure out 12” sections.  (The width is going to be 12”, but the length can be whatever, kinda like a bookmark.)

Step Two:  With the jigsaw, cut on the lines.

Step Three:  One the new 12” section, measure out every 3”.

Step Four:  Using the straight edge, draw your lines at every 3”.

Step Five:  Use a jigsaw to cut on the lines and make a lot of 3” x 12” sections.

Step Six:  With a knife, create a textured edge.  We trimmed off just the corners of one side and moved our write to create a more dramatic texture effect.  We even flicked or *popped* our wrist (like popping a tab off a pop can) to create an even MORE textured effect.  Let’s just say we were going for LOTS of texture.

Step Seven:  Spray paint your textured edges with your selected colors.

Step Eight:  Use the hot glue gun to put glue on the bottoms of your “stone” and stack them on top of each other.  We even placed glue on the backs of a few to keep the tower of foam stone attached to the wood column.
