Arrow Paving Inc. has completed thousands of commercial sealcoating projects across Connecticut over the past 60 years, and proper preparation is one of the biggest factors in achieving a long-lasting result. Knowing how to prepare your parking lot for sealcoating helps the process go smoothly, minimizes disruption to your business, and ensures the best possible adhesion and durability from the sealcoat material.
Start with a Pre-Sealcoating Inspection
Before any sealcoating work begins, your parking lot needs a thorough inspection to identify issues that should be addressed first. Walk the entire lot and look for cracking, potholes, oil stains, drainage problems, and areas where the pavement has settled or heaved. Document these issues so you can discuss them with your commercial sealcoating contractor. A professional inspection from Arrow Paving will identify problems you might miss and ensure that all necessary repairs are completed before the sealcoat is applied.
Complete Crack Repairs First
Sealcoating is a surface treatment, not a structural repair. Any cracks wider than a quarter inch should be filled before sealcoating to prevent water from penetrating beneath the surface. Professional crack filling uses hot rubberized material that flexes with the pavement through Connecticut’s freeze-thaw cycles. Applying sealcoat over unfilled cracks simply hides the damage temporarily while allowing water infiltration to continue undermining the pavement base. Crack filling should be completed at least 24-48 hours before sealcoating to allow proper curing.
Clean the Surface Thoroughly
Sealcoat needs a clean surface to bond properly. The parking lot should be cleared of all dirt, debris, leaves, and loose material before application. Power washing or mechanical sweeping is typically used to prepare the surface. Pay special attention to areas around dumpster pads, loading docks, and drive-through lanes where debris accumulates.
Oil stains require extra treatment because sealcoat will not adhere to petroleum-contaminated asphalt. Heavily stained areas near parking spaces, drive-throughs, and dumpster pads should be treated with an oil-spot primer before sealcoating. If stains have penetrated deeply into the asphalt, those sections may need to be cut out and patched before the sealcoat application.
Schedule Around Business Operations
For commercial properties, timing and logistics matter as much as the preparation work itself. Consider these scheduling factors:
- Business hours: Work with your contractor to schedule sealcoating during off-peak hours or weekends to minimize disruption to customers and tenants.
- Phased approach: Large parking lots can be sealcoated in sections over multiple days, keeping a portion of spaces available at all times.
- Curing time: Fresh sealcoat typically needs 24-48 hours to cure before vehicle traffic can resume. Plan for this downtime when scheduling.
- Weather window: Sealcoating requires dry conditions and temperatures above 50 degrees Fahrenheit. In Connecticut, the prime season runs from late spring through early fall.
Communicate with Tenants and Visitors
Effective communication prevents confusion and frustration during the sealcoating process. Property managers should notify all tenants at least two weeks in advance with specific dates, affected areas, and alternative parking arrangements. Post visible signage at lot entrances several days before work begins. For retail and office properties, consider notifying customers through your website or social media channels as well.
Provide clear directions to temporary parking areas and ensure that accessible parking spaces remain available or are temporarily relocated in compliance with ADA requirements throughout the project.
Plan for Traffic Management During Curing
Once sealcoating is applied, the treated areas must be barricaded to prevent vehicle and foot traffic until the material has fully cured. Work with your contractor to establish a barricade plan that includes cones, caution tape, and signage directing traffic away from freshly sealed sections. Ensure that emergency vehicle access is maintained at all times and that fire lanes remain clear.
