Step 1: Spray Your Mold

Grab two five gallons buckets and spray one with a mold release. This will help the concrete not stick to the bucket when it dries. We used this WD-40 Product: WD-40 Specialist Dirt & Dust Resistant Dry Lube Spray:

Step 2: Mix & Pour Concrete

Mix concrete in the bucket without your mold release. Once your concrete is fully mixed, pour it into the second bucket with the mold release product.

Step 3: Adding an Attachment Block

We need a way to attach the bench to the concrete. Grab a scrap piece of 2x4 and place it into the wet concrete. We screwed a temporary longer piece on to keep the block from sinking.

Step 4: Remove the Bucket & Trace

Remove the bucket by twisting the bucket back and forth. This will take some time. Move the concrete block onto a piece of 2" x 12" x 48" lumber and trace the shape.

Step 5: Round the Board & Sand

We used a circular saw to make a series of cuts that formed the curve. A jig saw would work much better here. Sand everything with 120grit and 220grit sandpaper.

Step 6: Attaching Wood to Concrete

Use 2.5" screws to attach the 2 x 12 to the concrete. We used 1/2" oak dowels to plug these holes.

Step 7: Attaching the Leg

Use some metal angle brackets to attach a board to the opposite end of the 2 x 12. This board should be cut to the same height as the concrete block. We used these brackets:

Step 8: Apply Your Finish

We chose this Spar Urethane which is great for outdoor use:
