Replacing a driveway can be one of the costliest home improvements out there. That's why most homeowners opt to seal an old, cracked driveway at least one or two times before seriously considering replacement. Sealing asphalt has long been a standard project, but what if you have a concrete driveway? They get cracks and surface damage, just like asphalt. Turns out, the answer may be the same for both asphalt and concrete: rubber driveway coating.
HyperRubber Parking Lot & Driveway is a rubber-based coating made by Hyperseal, a company known for rubber roof treatments and other specialty coatings. They've been in the news in recent years for developing a white rooftop paint with microscopic glass beads in it--all due to the efforts of one Col. Ronald Savin (Ret.), an octogenarian inventor who is still going strong. HyperRubber is non-toxic and is made with at least 50% recycled rubber. It can be applied with a roller or brush, making for an easy DIY project.
Why Seal Your Driveway
As mentioned, replacing a driveway is very expensive. Sealing asphalt or concrete helps it last longer and look better while you put off the inevitable replacement. The main enemy of any driveway is moisture. When cracks appear in a driveway (and they always appear in a driveway), moisture gets down into the paving and wreaks havoc. It erodes the base below the surface, leading to settling and holes. If it freezes, it expands and promotes more cracking. Sealing the driveway helps keep moisture out of cracks of all sizes, even those you can't really see. Large cracks are harder to cover and should be filled with a compatible caulk so the sealer can bridge over the top. Sealer also renews the look of a driveway by giving it a consistent color. You might not love the look of rolled-on rubber, but it's probably better than the unsightly splotches and veins of on old, cracked driveway surface.
Applying Rubber Driveway Coating
Like any plasticky surface coating, rubber driveway sealer sticks only if the underlying surface is clean and dry. Preparing an asphalt driveway requires just a thorough cleaning with a hose or pressure washer. Oily spots should be cleaned with a suitable degreasing cleaner, then rinsed thoroughly. Concrete surfaces should be washed with a muriatic acid solution, rinsed, then neutralized with sodium hydroxide and rinsed again. Let the driveway dry completely before sealing. Fill large cracks with a driveway caulk product that is compatible with the coating. It's easiest to apply the coating with a paint roller fitted with a long handle. You can also use a large paint brush for detail work and edges.
