Protecting and rejuvenating Pomona's driveways and parking lots with precision asphalt sealcoating.

This application typically includes cleaning the surface, addressing minor cracks, and then spraying or squeegeeing a uniform layer of an asphalt emulsion or refined coal tar sealer. The primary goal is to create a protective barrier against environmental damage, which means your pavement remains durable and looks new longer.
Our approach begins with a thorough inspection of your asphalt surface to identify any pre-existing damage, such as cracks larger than 1/4 inch or significant potholes, which require repair before sealcoating. We then use high-pressure air blowers and wire brooms to meticulously remove all dirt, debris, and loose aggregate. This ensures optimal adhesion of the sealcoat material, preventing premature peeling or flaking.
For properties in Pomona, sealcoating is especially critical due to the intense Southern California sun and occasional heavy rains. UV radiation from constant sunlight causes asphalt to oxidize, leading to fading, brittleness, and aggregate loss. A quality sealcoat blocks these harmful rays, maintaining the asphalt's flexibility and dark color. It also acts as a waterproof membrane, preventing water from seeping into the sub-base and causing structural damage, which is vital during our rainy seasons.
Homeowners often ask about the best time to sealcoat. We recommend sealcoating when the ambient temperature is consistently above 50°F and no rain is expected for at least 24-48 hours. This allows for proper curing and ensures the sealcoat achieves its maximum protective properties. We use commercial-grade sealers designed for high traffic and durability, providing a robust finish that stands up to vehicular wear and tear.
Asphalt sealcoating is essential in Pomona because it directly combats the specific environmental stressors common to our region. The relentless sun exposure in Southern California causes asphalt to dry out and become brittle, leading to surface cracking and aggregate raveling. A quality sealcoat provides a sacrificial layer that absorbs this UV damage, preserving the asphalt binder underneath.
Furthermore, Pomona's climate, with its hot, dry periods followed by occasional heavy downpours, makes asphalt vulnerable to water penetration. When water seeps into unsealed cracks, it can undermine the sub-base, leading to potholes and alligator cracking. Sealcoating fills hairline cracks and creates a water-resistant surface, effectively sealing out moisture and preventing costly structural failures.
Beyond protection, sealcoating significantly enhances curb appeal. A freshly sealed asphalt surface has a deep, rich black color that makes parking lots and driveways look well-maintained and inviting. This dark surface also absorbs more solar radiation, which helps to melt light frost or ice faster during cooler mornings, an added benefit for safety and convenience.
We begin by thoroughly cleaning the asphalt surface using industrial-grade blowers, wire brooms, and degreasers to remove all dirt, oil stains, and loose debris. Proper cleaning ensures maximum adhesion of the sealcoat material.
All cracks 1/4 inch or wider are cleaned and filled with hot-applied rubberized crack sealant to prevent water infiltration. Areas with oil stains are primed with an oil spot primer to ensure the sealcoat adheres uniformly.
We apply two coats of commercial-grade asphalt emulsion or refined coal tar sealer, depending on the project's specific needs and existing pavement condition. Each coat is applied uniformly using spray equipment or squeegees for consistent coverage and optimal protection.
After application, the sealed area is barricaded and allowed to cure for a minimum of 24-48 hours, depending on weather conditions. This curing period is crucial for the sealcoat to harden properly and achieve its full protective qualities before vehicle traffic resumes.
