After the countertop is sealed and the polish used, can the sealer be reapplied over the polish?
Yes. However, when first treating a new countertop, the sealer needs to be applied first, before any polish is applied. Afterward, the sealer can be reapplied periodically even after polish has been used on the countertop. For reapplying the sealer, the countertop should first be cleaned using the Stone Preserve Stone Countertop Cleaner.
