What Conditions Will the Sealer Be Exposed to?

To keep maintenance to a minimum, it's important to select a sealer that will protect your concrete or decorative overlay from the traffic conditions and elements to which it will be exposed. For example, for a stamped concrete driveway, you'll need a sealer that repels oil and grease stains, prevents penetration of water and deicing chemicals, and resists abrasion.

The primary type of sealer used for exterior concrete flatwork is a solvent- or water-based acrylic. If you don't want a sheen on the surface and prefer a natural look, a penetrating sealer is an alternative that provides excellent protection against outdoor exposure conditions.

For a decorative interior floor, a high-build sealer with good resistance to scuffs and staining, such as a polyurethane or epoxy, will generally provide the best protection and be easier to maintain. On indoor surfaces, softer acrylic sealers usually require regular maintenance with several coats of a sacrificial floor finish, or wax, to prevent wear and black heel marks.
