Asphalt Sealing

Anyone who has a driveway or parking lot (residential or commercial) can and should sealcoat it. Most people who opt to sealcoat do so because their driveway or parking lot is beginning to deteriorate. Think about when you pull into a surface that looks like it was recently sealcoated – it automatically boosts your perception of the property that you’re arriving at.

To sealcoat a driveway or parking lot, the first thing we do is clean the asphalt. We do this by edging the asphalt and getting rid of dirt found in cracks using power edgers. Additionally we take out any weeds that might be growing between the cracks, prep and pre-seal oil spots, and then blow everything off with power blowers to ensure the asphalt is clean of any debris before we being crack sealing and seal coating.

The final step before we sealcoat is repairing and filling all cracks with hot rubberized crack sealant.

After the above is complete we begin to sealcoat. This is done by applying Brewer Cote Fusion commercial grade sealcoat. We offer both 1 coat spray, 2 coat spray, and squeegee application.

Additionally, if it’s a commercial job, we offer parking lot striping. From simple striping, to extremely complex designs and patterns, Rock County Sealcoat can handle your parking lot layout and striping needs.

Why Sealcoat Asphalt?

Sealcoating your asphalt is an investment in your property. Sealcoating automatically increases the value of your property the same way remodeling, new additions, landscaping, or painting does. Put simply, it increases curb appeal and extends the usable life of your asphalt.

If you don’t sealcoat, your driveway or parking lot can appear gray and dull, which isn’t easy on the eyes. Regularly scheduled asphalt maintenance makes a huge difference. Also, when you’ve got a smooth surface, it makes cleaning it quicker and easier. A nice smooth black surface also helps snow and ice melt off your lot faster (which is a service we offer at Rock County Sealcoat, as well).

Sun, rain, and snow can and will deteriorate driveways and parking lots over time. Sealcoating prevents oxidation and drastically slows down the deterioration of asphalt, ensuring that your driveway or parking lot not only looks good, but lasts longer and saves you money in the long run.

When To Sealcoat Your Asphalt

It is recommended that you sealcoat your driveway or parking lot every 2-3 years, a general rule of thumb is that if you can see the color of the stones that make up the asphalt, it is time to sealcoat it. The best time of year to sealcoat your surface is May-October, with the optimal temperature being 60 degrees or above. It’s also worth noting that you shouldn’t touch or drive on a recently sealcoated surface for 24 hours after completion.
