We are concrete coatings company, not a concrete repair company.  We can make minor repairs prior to coating your concrete, however we cannot make structureally failed concrete look like new.  So, the short answer is that it depends on the amount of damage.  If you have driveway or patio that has large structural cracks…probably not.  If you have small cracks, we can fill them with our mender product prior to coating it.  Our warranty covers the coating we apply and not your existing concrete underneath it.
