Project Instructions

When working with cement-based products, always wear eye protection and waterproof gloves.

Step 1
Cut the wood into 2x4s and 2x6s, using a circular saw, and assemble into concrete forms for the two bases.

Step 2
Add appropriately sized melamine board or plywood to the bottom of the molds to keep concrete from spilling out.

Step 3
Mix the concrete, according to the instructions on the bag, and pour the mix into the molds.
Tip: Add wooden blocks with 3 inch screws in them to grip into the concrete and keep the weight down.

Step 4
Let the concrete cure for 3 days, and then, remove the molds with a prybar.

Step 5
Dig a square about 8 to 10 inches deep where you want each concrete base to the bench to go.

Step 6
Add about 3 inches deep of gravel within each of the hollowed out squares.

Step 7
Wheel the blocks to the holes and place them on top of the gravel.
Tip: You can place the blocks on the edges of the wood or a little closer to the center. It depends on what look you want for your bench.

Step 8
Level the bench by placing a 4x6 within the grooves and add gravel to each side to help it level out.

Step 9
Add the other two 4x6s and sand all three pieces of wood down.

Step 10
Cut grooves for the 2x2 short pieces across all 4x6s. Use a hammer and chisel to knock out wood chips to leave a clean hole.

Step 11
Cut the 2x2s to fit the groove and screw them in using 3 inch deck screws and sand down the edges.

Step 12 (Optional)
Finish the bench with a deck sealer for a cleaner, nicer look.
