Answer: Every other year
Explanation: The amount of activities your countertops are used determines how often they need to be resealed.

Answer: Every 2-5 years
Explanation: Because of the constant use of concrete countertops, they should be resealed at least 2-5 years depending on the sealer used. Some sealers are better then others. For instance, acrylic sealers are better then waxes, but epoxys, urethanes or polyaspartics are better then acrylics. On the flips side, mechanically polished concrete offers the most durability and scratch resistance.
