Step 1: Remove Loose Pieces and Debris

Remove any loose pieces of concrete and debris with the trowel hand tools. Clean up dirt, weeds and any other debris.

Step 2: Pressure Wash the Concrete

Pressure wash the concrete, working in one direction so the debris will flow in one direction. Get the area as clean as possible.

Step 3: Tape Off the Edges

Tape off the edges where you don't want new concrete.

Step 4: Prepare the Concrete Patch Mix

Use concrete with at least 3,000 PSI and good adhesion. The concrete comes with its own bonding agent. Put the powder in the wheelbarrow or cement mixer. Add liquid a little bit at a time to a peanut butter consistency. Only mix the amount that can be used in 20 to 30 minutes.

Step 5: Apply the Concrete Mix

Roll on a layer of bonding agent. Use a square nose shovel to put some concrete mix onto the top step. Use two trowels, one to lean on while working with the other.

Step 6: Fill the Holes

While working, use any leftover concrete mix that's getting kind of hard to fill the holes. Fill the hole and trowel over it to even it out. Smooth out hot spots with a trowel.

Tip: Use the edge of the trowel to smooth out the surface.

Step 7: Add a Second Coat

Add a second coat before the first coat dries.

Step 8: Create a Wetter Consistency

Mix the concrete to a wetter consistency -- a slurry like pancake batter.

Note: The purpose of the second coat is to give the concrete a nice "finished" look.

Step 9: Spray Water

To test, lay a little down and broom it. If a ball forms, it's too dry. If this happens, spray a little water on to dampen.

Step 10: Use a Concrete Finishing Broom

Drag the product across the entire surface with a concrete finishing broom.

Tip: To test if your concrete is too dry, run the finishing broom across the concrete and if little balls appear, it's too dry. Simply spray a little water on the surface and go over it again with the finishing broom.

Step 11: Work the Concrete Into the Pores

Work the concrete into the pores of the existing concrete.

Step 12: Add the Skim Coat

Add the skim coat over the entire area.

Step 13: Shape the Rounded Portions

For the edge of the step use a nose tool or nodder and use a cove tool or cover to shape the rounded portions where the steps meet.
