How Diamond Asphalt Handles Asphalt Sealcoating in Lafayette
Asphalt sealcoating is the application of a protective liquid layer, typically a refined coal tar emulsion or asphalt emulsion, over an existing asphalt pavement. This service includes a comprehensive cleaning of the surface to remove all debris, oil spots, and loose aggregate, followed by the meticulous sealing of cracks with hot-pour crack filler, and finally, the uniform application of one or two coats of high-quality sealer. Our process is designed to restore the pavement's aesthetic appeal and, more importantly, to create a barrier against the elements that cause deterioration.
Our approach begins with a detailed inspection of your Lafayette property's asphalt to identify any specific areas of concern, such as extensive cracking or severe oxidation. We then prepare the surface using industrial blowers, wire brooms, and, if necessary, power washing to ensure optimal adhesion of the sealant. For cracks wider than 1/4 inch, we use a commercial-grade, hot-applied rubberized crack sealant, which expands and contracts with the pavement, preventing water infiltration that can undermine the sub-base. This careful preparation is critical because it directly impacts the longevity and effectiveness of the sealcoat.
In Lafayette, CO, asphalt pavements endure significant stress from freeze-thaw cycles, intense UV radiation from high altitude, and the occasional heavy snowfall. These conditions accelerate asphalt oxidation, causing it to become brittle, fade, and develop surface cracks. Our sealcoating acts as a sacrificial layer that absorbs this environmental damage, preserving the underlying asphalt. It also helps to repel water and de-icing chemicals, which means less moisture seeping into the sub-base and fewer potholes forming during the spring thaw.
After the sealcoat is applied, we advise property owners to allow at least 24-48 hours for proper curing before driving on the surface, with cooler temperatures or higher humidity potentially requiring more time. We also recommend avoiding harsh chemicals or heavy scrubbing on the newly sealed surface for the first few weeks. Our team uses commercial-grade sealants that meet or exceed industry specifications, ensuring a durable finish that stands up to Lafayette's specific environmental challenges.
