CASTING A CONCRETE PATIO CHAIR

Traditional patio furniture is made of materials that do not wear well over time and exposure to the elements, so consider concrete as a durable alternative that can give your outdoor living space a cool appearance. In addition, it only takes a few bags of QUIKRETE to become on the only person in your neighborhood with concrete patio furniture.


Project Instructions

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

Step 1:
Seal any holes in the plastic chair frame, using old magazines, duct tape and hot glue, and tape off any larger openings or gaps, using duct tape.

Step 2:
Flip the chair upside down and use the blocks of wood to make sure it is level.

Step 3:
a) Mix the concrete mix, according to the instructions on the bag, and fill the seat and back of the mold. Use a wooden dowel to make sure the concrete mix fills to each of the corners, and vibrate the chair, to release any air bubbles.
b) QUIKTip: Adding QUIKRETE Liquid Cement Color to the mixing water, before mixing the concrete mix, is an easy way to add a more decorative touch and guarantees consistent color, throughout the mix.

Step 4:
Place anchor bolts where each of the four chair legs will be, for reinforcement.

Step 5:
Cut up four water bottles, to serve as the containing molds for the legs of the chair, and duct tape them to the chair.

Step 6:
Fill the leg molds with concrete mix, and push the mix down, to make sure it fills any voids. Again, vibrate to release any air bubbles.

Step 7:
Let the concrete cure for at least 48 hours, before removing the mold.

Step 8:
a)Pry off the mold, using a screw driver.
b) QUIKTip: To fully remove the mold, you may need to use a circular saw to cut it away. If this is the case, set the blade to 1/8 of an inch deep, and use wrenches as spacers, to avoid nicking the newly cast concrete surface. If you do not damage the mold in the removal process, you can reuse it to make another cast concrete chair.

Step 9:
Use an angle grinder to smooth any rougher edges.
