Align the block with the end of the base and place it down. Align the block before you place it down, to avoid visible adhesive. Repeat this process for the second side structure.

10. Paint the Blocks

Paint all sides of the cinder block structures with exterior house paint and a good painter's brush. Apply a heavy amount of paint so that it sinks into the nooks of the concrete blocks, and then brush away the excess paint. Check the edges for drips, and use the brush to remove them.

11. Sand the Posts

Apply a coat of wood stain and waterproofer with a wide paintbrush. Use long, smooth strokes to avoid brush marks. Turn the post once to paint the adjacent side. Allow the stain to dry for approximately one hour before turning it to paint the opposite sides of the post.

14. Remove Drips

Check the ends of the posts for drips and remove with the brush before they dry.

15. Assemble the Bench

Allow the painted blocks to dry overnight before assembling the bench. Move the two cinder block structures approximately 5 feet apart. Insert one end of a post through a hole in a cinder block and then into the opposite hole. Two posts will form the back support, and four posts will make the seat of the bench.

16. Align the Posts

Add a few plants and pillows and enjoy your new outdoor living space. You can spruce the space up even more by making a DIY torch to set beside the bench.
