Types of Exterior Sealers
Exterior sealers seal porous surfaces, acting as a beautiful top coat that delivers excellent protection for decks, fences, driveways, patios and walkways. They also protect the finish coat on masonry from alkalinity and efflorescence, and seal out moisture. This buying guide highlights the different types of exterior sealers available so you can pick the right one for your job.
Tip: Before applying a sealer, make sure your work surface is clean and free of loose wood or fibers. Some manufacturers combine the primer and sealer to save time during application. If you plan to paint over the sealer, look for a variety that says it can be painted, otherwise the paint may not adhere correctly.
