How do you repair a pothole in a concrete deck?

Repairing a pothole in a concrete deck requires more than just filling it. We square cut the edges (to avoid feather edging), break out the loose material, and prime the substrate. We then fill it with a high-strength, rapid-setting repair mortar (often epoxy or polyester based) that bonds chemically to the concrete. This ensures the patch doesn't pop out under the impact of vehicle wheels.
