Seal the deal on the question between oil and water driveway sealers with this rundown
Known for their high VOC levels and strong odors, oil-based sealers are less environmentally friendly compared to water-based sealers.
While homeowners can get up to six years of performance out of an oil-based sealer, they may need to remove the existing sealer before recoating a driveway.
While water-based sealers often last for just two years, recoating is simple.
If it's time to seal your driveway, you're facing the question of water-based vs. oil-based sealer for a driveway. While both can offer strong protection against wear and tear and the elements, everything from drying time to longevity can be different. Is an oil-based driveway sealer better if you don't want to get stuck frequently redoing this project? Check out the big difference between water and oil asphalt sealers to lock in your decision.
What Are the Differences Between Water and Oil Driveway Sealers?
Sealing your driveway is the best way to get your money's worth after paying the average asphalt driveway cost of $3,124 to $7,377. Which option does it best? Water-based and oil-based sealers both serve as protective coatings that shield your asphalt against rainwater, chemicals, and ultraviolet (UV) rays. However, they have different compositions that could impact their performance in specific conditions and environments.
Considered the more natural choice, water-based asphalt sealers are made using a mixture of water, limestone, and other organic fillers that are bound together with polymers to create a thick, smooth consistency that sticks easily to asphalt surfaces. By contrast, oil-based driveway sealers are made of a mix of petroleum solvents, asphalt binders, polymers, and other additives.
| Oil- vs. Water-Based Sealers | Oil-based | Water-based |
|---|---|---|
| VOC Content | High | Low |
| Odor | Strong | Low |
| Ease of Application | Easier | Moderately hard |
| Drying Time | Up to 10 hours | Less than three hours |
| Curing Time | 24–48 hours | 12 hours |
| Cleanup and Disposal | Challenging | Easy |
| Recoating | More difficult | Easy |
| Longevity | Up to six years | One to two years |
| Appearance | Shiny and smooth | Rougher |
| Traction | Slick | Gritty |
Safety and Environmental Differences
Like most homeowners, you may be worried about sealers leaching into the ground on your property. You might also have concerns about coming into contact with sealer fumes during application. Here's a look at how water and oil sealers compare.
VOC Content
In general, oil-based driveway sealers have higher levels of volatile organic compounds (VOCs) compared to water-based products. In addition to harming the environment, higher VOC levels come with risks of poor air quality at your home. This is where being an educated shopper counts! You can shop for oil-based driveway sealers that are marketed as being eco-friendly or low-VOC products. However, water-based driveway sealers win if you're looking for the more environmentally friendly option.
Odor
Oil-based driveway sealers can emit stronger odors during application. If you're sensitive to fumes, this could make application difficult. Always wear appropriate protective gear when applying any kind of sealer. If you determine that oil is the right way to go for your driveway because you're prioritizing longevity, hiring a company that handles professional asphalt sealing can help you avoid exposure to fumes.
Ease of Application Differences
Is it easier to apply water or oil driveway sealer? While one offers a quick application process, another is easier to clean up. Here's how they stack up.
Smoothness
The smoothness of oil-based sealers makes them easier to apply than their water-based counterparts. Oil-based sealers generally spread easily to allow you to fully cover the surface of your driveway without a lot of skill. Overall, this makes application both faster and cleaner. The thicker consistency of water-based sealers can make application "goopy" compared to oil products. In addition, the quick-drying nature of water-based products leaves less room for going back to correct mistakes.
Drying and Curing Times
Overall, waiting times are significantly shorter with water-based sealers. Water-based sealers tend to dry much faster following application than oil sealers. Freshly applied water-based sealer will usually dry anywhere from 10 minutes to three hours after application. However, curing times can last several hours. You can generally drive on a driveway that's been sealed with a water-based product in just 12 hours. By comparison, an oil-based sealer can take up to 10 hours to dry. It will be another 24 to 48 hours before the sealer is cured to the point that you can bring a car on the driveway.
Cleanup and Disposal
Designed to be water-soluble, water-based sealers only require water for cleanup. If you see any stubborn spots, mild soap should be enough to lift them. In addition, water sealers can generally be tossed in the regular trash. Just be sure to read the manufacturer's instructions for disposing of any water-based sealer you use beforehand.
Oil-based sealers generally require more vigorous cleanup. In addition to water, you may need to use a heavy-duty cleanser. You may also need to use a stiff-bristled brush to scrub away remnants. In general, unused oil-based sealer cannot be thrown in the regular trash. Based on the ingredients, you may need to follow your town's procedure for disposing of household hazardous waste when discarding a container that still has some product in it.
Recoating
If you need to recoat your driveway in a few years, a new water-based sealer can typically be easily applied over an existing coat. Depending on the condition of your driveway, the existing layer of oil-based sealer may need to be removed before the surface can be recoated. On average, companies charge $1 to $3 per square foot to remove old sealant.
Performance Differences
Which option lasts longer, performs better, and looks the best? While both can create safe and attractive driveways, differences in composition between water-based and oil-based products can create some differing results as time goes on.
Longevity
Is oil-based driveway sealer better for longevity? In general, homeowners can expect to get many more years out of each application when choosing oil-based over water-based driveway sealers. With the average driveway needing to be resealed every three to five years, an oil-based product's six-year average lifespan will put you slightly over that mark. Meanwhile, water-based sealers may need to be reapplied as frequently as once every two years to ensure that your driveway stays protected.
Oil-based sealers last longer because the oil within them creates a flexible barrier that can ebb and flow with the expansions and contractions that occur with temperature changes throughout the year. This makes oil an especially good choice if you live in a colder climate that experiences a frequent freeze-thaw cycle.
Appearance
When comparing water-based vs. oil-based sealer for driveways, products containing oil are necessary if you want that rich, shiny, and smooth finish that makes a driveway look like a mixture of freshly poured lava and velvet. Oil sealers produce a darker, glossier finish compared to water-based products. That extra coat of shininess helps to keep driveways looking newer for longer. While driveways sealed with water-based products can certainly look beautiful, they tend to have a duller finish. If you're not sure which option is ideal for your driveway, a local asphalt company near you can provide a recommendation to help you balance your desire for a safe, eco-friendly option with the practical need for longevity.
Traction
Oil-based sealers can leave slicker results than water-based sealers. Many water-based sealers for driveways are blended with sand to create a slightly grittier finish. If you're worried about slips and falls on your driveway, water-based products may make it safer.
Frequently Asked Questions
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.
Oil-based sealers generally offer longer results for driveways in cold climates. If you experience extreme temperatures, oil sealants offer a level of flexibility that makes them expand and contract along with the freeze-thaw cycle instead of cracking.
Driveway sealer needs warm, dry conditions to dry and cure properly. That's why spring, summer, and fall are the best times to apply sealer to a driveway. Avoid applying sealer in the winter when temperatures dip below 50 degrees Fahrenheit because cold weather makes curing difficult. Additionally, temperatures above 90 degrees Fahrenheit may make it impossible for sealers to dry properly.
