DIY Cinder Block Shelves

Use old cinder blocks and wood to make an affordable cinder block shelving unit for your outdoor space.

I have enjoyed working with my FLEXiO 4000 this summer making an Outdoor Planter Bench and restoring an Outdoor Swing. For this cinder block shelf project however, I used the Wagner FLEXiO 3000, which is ideal for smaller projects like this.

Materials and Tools

The cinder blocks and board cost less than $20 at our local hardware store.

For the best results, I highly suggest thoroughly reading through the instructions on how to assemble and use the sprayer. Likewise, be sure to do a test spray and practice with the included spray poster.

Step 2: Cut the 2x8x8 in half so that you have (2) pieces 4’ in length.

Step 3: Set up the spray tent. I used this HomeRight Medium Spray Shelter.

Step 4: Set up the FLEXiO 3000 according to the instructions. For exterior paint you will want to set it to MAX. Turn the nozzle so that it will spray horizontally.

Step 5: Arrange the cinder blocks on top of an old board or plank to raise them up off the ground a bit. Spray the cinder blocks from all angles so that both the outside and inside are coated with paint. Take your time with this step. Once the blocks are dried, flip them over and repeat.

Step 6: Place the boards across two sawhorses and spray in a horizontal pattern holding the sprayer 6-8 inches from the surface. Once the paint dries, turn the boards. Repeat until all the sides are painted.

Using the FLEXiO 3000 made this project take considerably less time than if I had hand painted it. I just love the way this project came out! It’s ideal for our patio next to the pool!

The best part is that clean up is a cinch! It literally takes only 5 minutes to rinse it all out so switching from one paint color to the next was a snap. Plus, I love that it comes in its own case for storage.
