Sealcoating Contractor Checklist
Updated July 6, 2026
Before hiring a sealcoating contractor, confirm surface cleaning and crack sealing happen before sealcoat is applied, ask what product and how many coats are used, confirm weather and cure requirements, and get a plan for scheduling around tenants or residents.
Sealcoating can extend the life of asphalt pavement, but the results depend heavily on surface preparation and application conditions. Use this checklist before hiring a sealcoating contractor.
Surface preparation
Confirm the contractor will clean, degrease, and sweep the surface before application, and that cracks will be sealed prior to sealcoating rather than after. Oil spots and other petroleum stains often need a primer or spot treatment before sealcoat will adhere properly.
Materials and application
Ask what sealer product will be used, how many coats are included, and the application rate. Confirm whether the mix includes sand or other additives for traction and durability, and whether the number of coats is appropriate for your traffic volume.
Weather and cure time
Sealcoating requires specific temperature and weather conditions to cure properly — typically above a minimum air and pavement temperature, with no rain expected during the cure window. Ask what the contractor's plan is if weather delays the project, and how long the surface needs to cure before it can be reopened to traffic.
Scheduling around tenants or residents
For commercial properties or HOAs, confirm how the contractor will communicate closures, coordinate parking access, and sequence the work (often in sections) to minimize disruption.
Frequently asked questions
How often should parking lots be sealcoated?
Typical cycles range from every one to three years depending on traffic volume, climate exposure, and prior condition. A maintenance contractor can recommend a schedule based on your specific lot.
Should cracks be filled before sealcoating?
Yes. Cracks should generally be routed and sealed before sealcoating is applied, not after, so water intrusion is addressed before the protective coat goes down.
How long does sealcoat need to cure before a lot reopens?
Cure time varies by product and weather conditions, but many sealcoat applications need at least 24 hours before light vehicle traffic. Ask the contractor for a specific timeline for your project.
Does sealcoating cover up oil stains?
Sealcoat can improve the appearance of light oil staining, but heavier petroleum contamination often needs a primer or spot treatment first, or the stain can bleed back through or cause adhesion problems.
