Sealcoating is one of the main services GK Asphalt provides. Sealcoating extends the life of your asphalt parking lot or driveway by applying a protective layer of sealant over the asphalt. Since asphalt is a porous substance constantly exposed to harsh elements, weather, sunlight, chemicals, and wear and tear, sealcoating helps ward off cracks and surface damage. 


Our expertise allows us to determine the most effective, durable, and appropriate application method—brush, spray, or squeegee— for your asphalt driveway or parking lot. 


Gary Kessler, Jr., owner of GK Asphalt, has been working in the sealcoating and asphalt maintenance industry since 1994, with hundreds of residential driveways and commercial parking lots of all shapes, sizes, and conditions under his belt. During this time, Gary has grown a solid base of industry knowledge regarding asphalt products, equipment, application techniques, and state-of-the-art repair methods.

Why are spring and summer good times to sealcoat? 

Spring is a good time to sealcoat your asphalt driveway or parking lot for several reasons. The brighter sunshine, winds, and warmer weather help the sealant dry faster and more thoroughly; ideal sealcoating temperatures are 50º and above. Less drying time means you can use your driveway or parking lot more quickly. Also, the harsh rays of the summer sun take a toll on unprotected asphalt, leaving it porous, brittle, and susceptible to cracks and damage. Just like your skin needs sunblock, your driveway or parking lot needs a coat of sealant to protect it from sun damage. Finally, a fresh coat of sealant restores your asphalt’s color and appearance after a long winter of wear and tear from cold weather, snow, and salt applications.

How does winter weather damage asphalt? How can it be prevented?

During the winter months, asphalt damage occurs from a number of sources. Freezing temperatures, snow, and ice can lead to cracks in the asphalt surface. Snow plowing and chemical ice treatments such as salt spreading can further damage the asphalt, worsening cracks and causing pot holes. Although the optimal time to sealcoat is spring and summer, you can still have your asphalt driveway or parking lot sealcoated during the fall, before the temperature dips. It is preferable to finish all sealcoating before leaves fall and blow onto the asphalt surface to be sealed, and temperatures need to be 50º or above, so the asphalt can thoroughly dry. On clear, warm, windy fall days, the sealer can dry in no time! Also, fall is an ideal time to fill cracks in the asphalt so they don’t worsen when exposed to winter’s harsh weather and snow and ice removal. When asphalt cracks, water and debris penetrate through the asphalt layers as the asphalt expands and contracts with temperature and weather changes, worsening the problem. The longer cracks remain untreated, the more they deepen and spread, which can eventually lead to the costly undertaking of repaving sections or entire driveways or parking lots. Any existing potholes or depressions should also be filled so water doesn’t accumulate and freeze.  




What are some benefits of applying sealer with a brush?

There is great debate about how to best apply sealer, with spraying and brushing applications both having benefits and drawbacks. Brush sealer application allows for a thicker application of sealer that penetrates tiny spider cracks and grooves in the asphalt surface better than using a flat squeegee or spraying due to the coarseness of the brush bristles. It also prevents overspray onto nearby sidewalks, concrete areas, and buildings. However, if the sealcoating company you use doesn’t know how to properly brush on sealer, it can result in too thick of an application. This can affect how the sealer cures, leaving behind a job that doesn’t last as long as it should. It can also cause the surface to become slippery because the natural traction of the asphalt has been too heavily coated. Sand additives can help counteract a slippery surface, but it is most important a brush sealer application be performed by an experienced sealcoating contractor that applies the right amount of sealer using proper brushing techniques.


How long does it take for sealer to dry?

Sealer dries fairly quickly on a clear day, usually within 5 hours or so. At this point, it is okay to walk lightly on the surface, if necessary. However, to allow the sealer to fully dry without track marks from tires, the asphalt area should not be driven on or receive high foot traffic for 24 hours. Weather plays a factor in how long it takes freshly applied sealer to dry; if there are high temperatures, sunshine, and wind, it dries much faster than if it is cooler or overcast outside.




Why fill cracks in the asphalt surface?

Cracks in the surface of asphalt parking lots or driveways occur due to wear and tear, improper drainage, and exposure to weather. These elements weaken the asphalt surface over time, leaving it susceptible to damage. When asphalt cracks, water and debris penetrate through the asphalt layers as the asphalt expands and contracts with temperature and weather changes, worsening the problem. The longer cracks remain untreated, the more they deepen and spread, which can eventually lead to the costly undertaking of repaving parts of the area, or even the entire driveway or lot. In some cases, the old asphalt surface is so damaged, it needs to be removed and totally replaced with fresh asphalt, which costs even more. Having an experienced professional like GK Asphalt fill asphalt cracks ensures the job is done properly and neatly, cures correctly, and lasts. It also minimizes the potential for mess that usually occurs when someone inexperienced attempts to fill the cracks using store-bought filler. Remember, proper and regular asphalt maintenance, such as sealcoating, helps keep asphalt in tip-top shape. Sealcoating keeps asphalt from weakening and drying out, which can lead to cracks and damage down the road. Please note, filled cracks provide damage protection, but they are always visible on the asphalt surface because the rubberized filler material is different than the asphalt and sealcoating material.
