Best driveway sealcoating pros near Charlo, MT

No. You cannot use asphalt products on concrete driveways. To seal a concrete driveway, use acrylic, epoxy, polyurethane, silane, siloxane, and silicate sealers or deep penetration sealers made specifically for concrete. Meanwhile, asphalt sealers contain refined coal tar (asphalt emulsion), water, sand, clay, polymers, and additives and are incompatible with concrete’s surface texture and higher density.

Yes, it’s possible to seal your driveway too much. Whether you have an asphalt or concrete driveway, sealing it every year opens your driveway to potential damage. Sealing an asphalt driveway annually may cause the seal to crack and peel even more. It may even trap oils within the asphalt that can leave you driving on a soft driveway. Avoid sealing your concrete driveway too much to prevent the concrete from cracking. If water enters these cracks, it can freeze, expand, and cause the cracks to worsen.

If the goal is to reduce your lifetime asphalt driveway repair cost, driveway sealers with oil bases tend to last longer because their composition allows them to penetrate deeper into your driveway's asphalt. This provides deeper, longer-lasting protection compared to water-based products that tend to simply sit on the surface of the asphalt. Knowing that you won't have to redo your driveway as often could leave more room in your budget to cover something like the cost of a heated driveway.

You shouldn’t directly paint over an oil stain on your asphalt driveway. While painting over might visually conceal the stain, the oil will continue to damage the driveway. Once you’ve noticed the oil stain, it’s important to thoroughly remove it within the next few months since oil stains only take six months before they begin to damage the structure of your asphalt driveway.
