Seal coating is a protective liquid coating applied to asphalt pavement to extend its lifespan and prevent deterioration. Think of it as sunscreen for your parking lot—it creates a barrier against the elements that damage asphalt: UV rays, water, oils, and oxidation.
In Ontario, seal coating is particularly critical because of our extreme climate. Summer UV exposure breaks down asphalt binder, making the surface brittle. Fall and spring rain infiltrates small cracks, and when temperatures drop below freezing in winter, that water expands—creating larger cracks, potholes, and surface failure.
Professional seal coating done right stops this cycle. Applied every 2-3 years, it's the single most cost-effective way to protect your asphalt investment. The alternative? Watching your parking lot deteriorate until the only option left is expensive resurfacing or replacement.
Why Ontario Properties Need Seal Coating
Protection that pays for itself by preventing expensive repairs
Protects Against UV Damage
Ontario summers are hard on asphalt. UV rays break down the binding agents that hold aggregate together, causing oxidation and surface deterioration. Seal coating blocks UV penetration and keeps your asphalt flexible.
Prevents Water Infiltration
Water is asphalt's biggest enemy. When it seeps into small cracks and freezes during Ontario winters, it expands and creates larger damage. Seal coating creates a waterproof barrier that stops infiltration before it starts.
Slows Oxidation & Aging
Unsealed asphalt turns gray and brittle as it ages. This is oxidation—exposure to oxygen breaks down the asphalt binder. Seal coating slows this process dramatically, keeping your pavement dark, flexible, and resilient for years longer.
Extends Pavement Life 2-3x
An unsealed parking lot in Ontario might last 10-12 years before needing replacement. With regular seal coating every 2-3 years, that same lot can last 20-30 years. The math is simple: pennies per square foot now saves dollars later.
Our Seal Coating Process
Surface Preparation
We start with a thorough cleaning using industrial blowers and power brooms to remove dirt, debris, and loose material. Any vegetation growing in cracks is removed, and oil spots are treated with primer. Proper prep is 50% of a quality seal coat job.
Crack Filling First
All cracks ¼" or wider are filled with hot-pour rubberized crack filler before seal coating. This prevents water infiltration and gives you a smooth, uniform surface. Cracks must be addressed—seal coating alone won't fix them.
Commercial-Grade Sealer Application
We apply two coats of commercial-grade coal tar or asphalt emulsion sealer using professional spray equipment. Each coat is applied evenly at manufacturer-specified thickness (not watered down). High-traffic areas get extra coverage.
Curing & Protection
Seal coating needs 24-48 hours to cure depending on weather conditions. We coordinate timing with your worship schedule and events so your lot is ready when you need it. We also monitor weather forecasts—no work starts if rain is predicted within 24 hours.
Seal Coating Cost & Timing
Typical Ontario Pricing
Most Ontario parking lots cost $0.20-$0.35 per square foot for professional two-coat seal coating, including surface prep and crack filling. Faith communities typically pay:
- Small lots (5,000-10,000 sq ft): $1,500-$3,000
- Medium lots (10,000-20,000 sq ft): $3,000-$6,000
- Large lots (20,000+ sq ft): $6,000-$12,000
Important: Every lot is different. Size, condition, accessibility, and amount of required crack repair all affect final cost. Our free drone inspection provides an accurate quote with no surprises.
Best Time for Seal Coating in Ontario
Seal coating requires temperatures above 10°C (50°F) and low humidity for proper curing. In Ontario, this means May through September is your seal coating season. We typically book faith communities in late spring (May-June) and late summer (August-September) to avoid peak heat and ensure optimal curing conditions.
Frequently Asked Questions
What does seal coating actually do for asphalt parking lots?
Seal coating protects asphalt from water penetration, UV oxidation, road salt, and surface wear. It helps extend the life of a parking lot and improves appearance but does not fix structural damage.
How long does seal coating last in Ontario's climate?
In Ontario, seal coating typically lasts 2–3 years, depending on traffic levels, sun exposure, and whether cracks are properly maintained.
How long does a seal coating project take to complete?
Most church and commercial parking lots can be seal coated in one day, with 24–48 hours required for curing before vehicle traffic resumes.
Can seal coating be done around church schedules and services?
Yes. Seal coating is commonly scheduled mid-week to avoid weekends, worship services, and special events, minimizing disruption.
