COMMERCIAL PARKING LOT SEAL COATING
FineLines completed a commercial seal coating application on a parking lot in the Hamptons, New York, protecting the surface against weather, freeze-thaw cycles, and heavy daily use.
A seal coat acts as a barrier between the asphalt and the elements that break it down fastest, sun, moisture, and repeated freezing and thawing through the winter months. Applied properly, it slows oxidation, reduces water penetration, and extends the useful life of the existing surface.
Before the seal coat was applied, the crew addressed existing surface cracks through crack filling, sealing them off so moisture couldn't work its way into the base beneath. Skipping this step and sealing over open cracks traps water rather than keeping it out, so proper crack repair ahead of coating is part of doing the job right.
A seal coating project like this one typically involves:
- Cleaning the surface to remove debris and buildup before application
- Filling and sealing existing cracks
- Applying the seal coat evenly across the full lot
The Hamptons sees a real mix of seasonal stress on pavement, salt air and coastal humidity through the warmer months, followed by freeze-thaw cycles in winter that work their way into any unprotected cracks. A properly sealed surface, with cracks addressed first, holds up significantly better against that combination than an unsealed lot exposed to the same conditions year after
