Repair concrete countertop crack

by Robin

Q. I have a crack that appeared just after we poured our countertop. It seems to go all the way through (I can see it on the edge) it has not been sealed, and has been about 10 days since it was poured, and the form/brace hasn't been removed. How can we fix this? I have only seen how to repair hairline cracks.

A. The only way to repair a crack that goes all the way through the countertop is to drill some small holes in the crack, about every 6 inches and inject the crack with an epoxy crack repair material. This will "weld" the crack back together.

You can use a clear, 2 part, fast setting epoxy. This can be purchased at most concrete supply stores.
