Benefits of Sealcoating:
Parking lot sealcoating helps to project a positive image for your company, facility, or residential complex. When covered with a black asphalt sealant, pavement looks and wears like new. Additionally, sealcoating requires a clean, dry surface which means when we are done, your pavement will be clean and free of debris.
All asphalt pavements consist of aggregates and binders. Over time, environmental factors such as water, UV rays, oil, gas, and detergents wear away the tar and petroleum additives that bind the aggregates together. This wear gives your pavement a white, faded appearance. Regularly applying asphalt sealer restores these critical binders thereby increasing the integrity and life of your pavement surfaces.
Sealcoating acts as a protective barrier between the pavements surface and caustic elements. This barrier reduces the depth to which oil or gas can penetrate the pavement. Gasoline dripping from a topped-off fuel tank during hot weather can soften and break down unsealed asphalt pavements. Coal tars used in sealcoat are impervious to gas and oil spills.
Sealcoating also acts as a weatherproofing agent. It helps to limits exposure to oxygen and UV rays which damage and dry-out the binders in your pavement. A properly sealcoated pavement surface also minimizes the rate at which water can enter the pavement. Without it, water can permeate more freely allowing for the sub-base and base rock to be washed out.
By restoring the pavements natural binders and continual protection against the elements, sealcoating can greatly extend the life of your pavement. On average, a properly maintained asphalt surface should be sealcoated one year after its initial construction and every two years after. Investing in your property through regular sealcoating can add 10-15 years of usable life to your pavement surface.
- Cost Effectiveness
Sealcoating preserves asphalt for pennies per square foot. The price of asphalt will always be affected by crude oil prices, which fluctuate when supplies vary. Because of this, re-paving usually 3-5 times more expensive then sealcoating.
Prior to sealcoating, any structural failures or cracks on the pavement must be repaired. All potholes must be removed and replaced with new asphalt , cracks must be cleaned and filled with cracksealant , and oil spots cleaned or primed. Finally, the entire surface of your pavement will be cleaned using a high powered air blower and roadway brooms.
Once the pavement surface is ready, the asphalt sealcoating will proceed according to a pre-approved schedule.
Sealcoating should only be performed under the proper weather conditions. The recommended air and pavement temperature should be at least 55 degrees Fahrenheit and rising during the application of sealer and for 8 hours afterward.
Traffic should be kept off a newly sealed surface for a minimum of 18 to 36 hours to allow for drying (curing) time. If this time frame is not practical, Duraseal will work with you to develop a schedule that works for you. It is also important to refrain from using sprinklers near the area, hosing down, or washing the area for 48 hours before and after work is completed.
