Determine the location and layout of your new sidewalk. Prepare the surface by digging up grass and raking. Place a 4-foot level on the ground and fill in any low spots with dirt, so that water does not puddle on your finished sidewalk.
Pour dry concrete into your wheel barrel and mix with your shovel, according to package directions. Mix in concrete dye, if desired, according to package directions. Start at one corner of your sidewalk cite, and put your mold on the ground.
Place your 2-foot level across the top of your mold, and make sure your mold is positioned flat and level on the ground.
Scoop concrete into each cavity of your mold with a shovel until full to the top. Pat down the wet concrete and smooth with your trowel to even it out.
Lift your mold straight up and out of the wet concrete. Moisten your trowel with water and use it to smooth out any uneven edges.
Add texture to the top of the concrete with your stiff brush to aid in creating a non-slippery surface. Rotate your mold 90 degrees to vary the design and butt your mold up against the previous section. Repeat Steps 3 to 6 until the entire sidewalk is done.
Cover your wet concrete sidewalk with plastic sheeting for five days to cure. Remove plastic and use a paint roller to apply acrylic concrete sealer to your clean, dry concrete sidewalk. Wait an additional 24 hours before allowing foot traffic.
