Basic Concrete Countertop

Step 11: Slurry Fill any Holes or Cracks

It's important to know your color to concrete ratio if you're using tint in the mix so you can mix a slurry with the same ratio. We did two slurry passes: the first made with the same Quikrete 5000, the second with Fu-Tung Cheng's slurry mix. This is applied with a trowel or putty knife, allowed to dry, then sanded down to smooth it. The holes and cracks filled nicely, and while the top was nice and smooth when we finished, the thing we noticed was a lack of the same "granite" look to the finish in the 3 large cracked areas.
