What Is the Life Expectancy of the Sealer, and Does the Manufacturer Provide a Warranty?

The life expectancy of a sealer depends, in part, on exposure conditions and how well the sealer is maintained. In general, however, epoxies and urethanes deliver the best long-term performance and can last years before the need for reapplication. Some manufacturers may even provide a warranty to back the performance claims for their products. However, this warranty will be null and void if you don't adhere to the manufacturer's guidelines when applying the sealer.

Notice that cost is not one of the key considerations listed here. Certainly, you should compare prices of similar products to get the best value, but don't try to pinch pennies. Sealer is too important to the overall appearance and longevity of your work. Plus, you don't want to give your clients a protective finish that will wear away after only a year or so. "When it comes to sealers, you really do get what you pay for. Save now, pay later is often the result of going cheap," says Sullivan.
