How to Lay a Brick Sidewalk in Cement

Brick sidewalks bring warmth, color and earthy texture to a surface. Installing them over cement is an efficient way to utilize a strong, existing surface while giving the plain gray slab a stylish new look. Setting bricks over cement is not difficult. Once complete, your new sidewalk will last for many years and require little maintenance.

Instructions

    • 1

      Clean the cement with a wire brush and hose to remove embedded dirt. Use a cement stain remover to scrub off any grease stains so they don't weaken the bond between the mortar and bricks, and rinse off the remaining solution.

    • 2

      Repair any pits or cracks using vinyl cement-patching compound and a putty knife.

    • 3

      Set one section of bricks over dry cement to decide on your pattern. Try traditional patterns like half basket weave and herringbone, or create your own design. Once set in mortar, you won't be able to alter the pattern so take the time to find one you'll enjoy for many years.

      Mix mortar with pre-made mortar mix and small amounts of water until it has a toothpaste-like texture. Refer to the manufacturer's instructions to see how much mortar you'll need in order to spread a ½-inch layer over the cement. If the surface is large, mix the mortar in small batches so it doesn't begin to harden before you use it.

      Spread a ½-inch layer of mortar over the cement on one end of the sidewalk using a notched trowel. Only lay enough mortar to set about four bricks at a time.

    • 6

      Lay the bricks in the mortar according to your pattern. Set them flush so the space between each brick is consistent and narrow. After each section, set a board across the bricks and tap the board with a hammer to make them even. Continue setting the bricks in small sections following you pattern. Wait two days for the surface to set in the mortar.

      Cover the sidewalk with masonry sand. Us a stiff shop broom to sweep it back and forth so it falls between the cracks, forming sand joints between the bricks. The sand stops debris buildup and helps keep the bricks in place.
