Standard parking lot sealcoating needs reapplication every few years. Learn when a maintenance coating like DuraShield makes more sense for your lot.
Every property manager knows the cycle: the parking lot starts looking grey and worn, you bring in a sealcoating contractor, the lot looks fresh for a season or two, and then you do it again. Parking lot sealcoating has become a line item that shows up every few years, and most people accept it as part of the cost of owning asphalt. But it doesn't have to be.
The question worth asking is whether each coat maintains your pavement or only covers it up on a schedule. There's a difference, and for REITs, facility teams and property managers running commercial lots, that difference shows up in lifecycle costs, downtime and long-term asset value.
What conventional sealcoating does (and doesn't do)
Standard coal-tar or asphalt-emulsion sealcoats serve a purpose. They restore the black appearance of oxidized asphalt and provide a modest barrier against UV exposure and water penetration. For a residential driveway with light traffic, that can be enough.
Commercial parking lots are a different story. They take a disproportionate beating: sun exposure, oil contamination from parked vehicles, fuel drips, de-icing salt in winter, and constant wheel-load cycles from turning and braking. A thin sealcoat film doesn't resist these forces for long. The surface wears through, especially in drive aisles and high-traffic bays, and you're back to scheduling another application.
The recurring cost goes beyond material and labour: closure time, coordination with tenants, traffic control, and the fact that you're never really getting ahead of the problem. You're resetting the clock, not extending the pavement's life.
How a maintenance coating differs
DuraShield is a two-component, epoxy-modified acrylic maintenance coating for asphalt. The difference from a sealcoat starts with the chemistry: a two-component system cross-links as it cures, creating a harder, more durable film than a single-component emulsion that simply dries.
DuraShield resists fuel, oil and de-icing agents. That matters in a parking environment where those exposures are constant. It also offers solar-reflective options (the SR Gray formula has a solar reflectance of 0.35), which can reduce surface temperatures and contribute to heat-island mitigation on LEED sites.
The purpose isn't cosmetic. DuraShield protects the substrate underneath, extending the life cycle of the pavement instead of just covering what's already degrading. For a lot where the asphalt is still structurally sound but the surface is oxidizing and losing aggregate, a maintenance coating can defer replacement by years.
When colour makes sense in a parking lot
Surface protection is one part of the picture. Wayfinding, safety and branding are another. If you've driven through a well-managed retail or institutional lot, you've seen coloured drive aisles, fire lane designations and pedestrian zones that read clearly from a distance. That colour isn't paint.
StreetBond is a water-based, epoxy-modified acrylic coating designed to move with the pavement. Rigid coatings crack, wear prematurely and become slippery. StreetBond avoids those failures because the formulation is engineered for Canadian conditions: plows, de-icing seasons and freeze-thaw cycles.
In a parking lot, StreetBond creates:
- Fire lane designations that read clearly and last, without annual repainting
- Drive aisle colour that separates circulation routes from parking bays
- Wayfinding zones that guide traffic to entrances, pick-up areas or reserved sections
- Branded areas where surface colour reinforces the property's identity
With 63 standard colours plus custom colour matching and a life cycle of 8+ years (easily refreshed rather than rebuilt), StreetBond treatments last far longer than traffic paint and add aesthetic value while preserving the underlying asphalt.
Deciding between maintenance and replacement
Not every lot is a candidate for coating. The question is whether the asphalt underneath is worth protecting.
| Condition | What it means | Recommended approach |
|---|---|---|
| Surface oxidation, minor aggregate loss, no structural cracking | Asphalt is sound; surface is aging | Maintenance coating (DuraShield or StreetBond) |
| Alligator cracking, base failure, potholes | Structural damage; substrate compromised | Repair or replace before coating |
| Faded but intact surface with heavy oil staining | Coating will adhere if properly prepared | Maintenance coating after cleaning and prep |
| End-of-life asphalt with widespread failure | No point protecting what's already failed | Full replacement |
A maintenance coating on failed asphalt is a waste of money. A full replacement on sound asphalt is also a waste of money. The assessment matters, and it's worth having someone who understands pavement conditions look at the lot before you commit to either path.

The property management calculation
For REITs and facility teams managing multiple properties, the appeal of a longer-lasting coating is straightforward: fewer interventions, less tenant disruption, and a surface that looks maintained between applications.
There's also a brand dimension. Canada's top REITs are specifying decorative pavement because surface systems reduce maintenance costs over time while improving asset presentation. A parking lot that looks sharp reflects on the property. One that's perpetually faded and patched sends a different message.
DuraShield and StreetBond fit into this picture as tools for managing pavement as an asset rather than an expense. The lot stays protected. The colour stays legible. The cycle of recurring sealcoating applications gets replaced with a longer interval and a better result.
Specifying the right coating for your lot
The starting point is understanding what you have. If the asphalt is sound and you want protection without colour, DuraShield is the maintenance coating. If you want colour for wayfinding, fire lanes or branding (with the preservation benefits built in), StreetBond is the system. For high-traffic bays and crossings where durability demands are highest, other systems like TrafficPatternsXD come into play.
HUB's spec sheets for DuraShield and StreetBond are available at hubss.com/resources. For design teams working through a parking lot specification, HUB runs Lunch & Learn sessions that cover system selection, surface preparation requirements and lifecycle expectations. If you're managing a lot that's due for its next sealcoating cycle, it might be worth a conversation about whether there's a better approach.
