Cementious dye Note: To determine if your concrete needs repair, tap the concrete with a scraper to test. You want to hear a ping sound, not a hollow sound. - Gather the tools and materials.
- Remove any lose pieces of concrete and debris with the trowel hand tools. Clean up dirt, weeds and any other debris.
- Pressure wash the concrete, working in one direction so the debris will flow (figure A) in one direction. You must get the area as clean as possible.
- Tape off the edges where you don't want new concrete.
- Prepare 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 your wheelbarrow or cement mixer.
- Add liquid a little bit at a time to a peanut butter consistency (figure B ).
- Only mix amount that you can use in 20 to 30 minutes.
- Roll on a layer of bonding agent -- shovel some concrete mix onto top step -- use two trowels, one to lean on while you work with the other (figure C).
- As you're working, use any leftover concrete mix that's getting kind of hard to fill the holes -- fill hole and trowel over it to even it out.
- Smooth out high spots with a trowel.
Tip: Use the edge of the trowel to smooth out the surface. - Add a second coat before the first coat dries.
- Mix concrete to a wetter consistency -- a slurry like pancake batter (figure D).
Note: The purpose of the second coat is to give the concrete a nice "finished" look. - To test, lay a little down and broom it, if you get a ball it's too dry. If this happens, spray a little water on to dampen.
- 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. - Work the concrete into the pores of the existing concrete.
- Add skim coat over entire area.
- For the nose of the step (edge) use a nose tool (called a nodder), and at cove of the step (where steps meet) use a cove tool (called a cover) to shape rounded portions (figure E).
