Mix warm water and mild dish soap in a bucket to make a cleaning solution. Dip the sponge into it and wipe on the entire area around the damage. Make sure that the chipped portion of the quartz, as well as the surroundings, have been thoroughly cleaned of debris, grease, and any form of dirt otherwise your patch job may not take.
Wipe the surface with a clean, dry towel after scrubbing it clean, and leave for at least one hour to dry. The surface of the countertop must have no moisture remaining on it before going on to the next step of the repair process.
Protect the surrounding areas of the countertop by taping them off with masking tape. Only the portion that needs to be repaired should be visible or not covered. Likewise, keep appliances, wires, and power outlets secured and protected. They may also be covered with masking tape to ensure they stay in optimum condition while you are working.
