As winter approaches here in Vancouver, many of us start preparing for the cold. But while we’re getting winter-ready, have you thought about how your asphalt feels about the upcoming season?
Yes, even the pavement under your car needs a little extra care to get through the chill and wetness of winter. That’s where seal coating comes in.
Seal coating is like giving your asphalt a winter jacket. It’s a protective layer that keeps out water, UV rays, and oil. All these things can damage and age your pavement over time.
In this guide, we’ll walk you through everything you need to know about seal coating before winter hits. You’ll learn why it’s so important and how it helps asphalt last longer.
Benefits Of Seal Coating
Here are some of the top benefits of seal coating, especially for Vancouver’s unique climate:
- Water Protection: Seal coating stops water from entering the asphalt, helping prevent cracks, potholes, and other costly damage.
- UV Ray Protection: The sun may not be as strong in winter, but UV rays still weaken asphalt over time. Seal coating keeps those rays at bay.
- Chemical Resistance: Oil and gas from vehicles can eat away asphalt. A seal coat layer keeps these chemicals from causing damage.
- Cost Savings: Regular seal coating costs far less than frequent repairs. Small steps now save big bucks later.
When To Seal Coat
Seal coating isn’t a job for freezing weather. It needs a bit of warmth to set and cure properly. The best time for seal coating in Vancouver is during the warmer months – think late spring to early fall.
The ideal conditions for seal coating are temperatures above 10°C (50°F) and dry weather. Once the sealant is applied, it takes about 24 hours to cure, so planning ahead is key.
How To Prepare Your Asphalt For Seal Coating
Preparation is key for a smooth, long-lasting seal coat. Follow these steps to get your asphalt ready for its winter jacket:
1. Clean The Surface Thoroughly
Dirt, dust, and debris can prevent the seal coat from sticking to the asphalt. Sweep away loose debris and, if necessary, use a power washer to get a truly clean surface.
2. Repair Any Cracks Or Potholes
Seal coating won’t magically fix cracks or potholes. Fill in any visible damage first. You want a smooth surface to work with.
3. Remove Oil Stains
Oil spots can stop the sealant from bonding to the asphalt. Use a degreaser to remove these stains before sealing the coating.
Types Of Sealants To Consider
Sealants come in a few varieties, each with its benefits. Choosing the right one can make a big difference, so here’s a quick guide:
- Coal Tar Sealants: Very durable and resistant to oil and chemicals, but they have a strong smell and aren’t the most eco-friendly option.
- Asphalt Emulsion Sealants: These are more environmentally friendly and have a milder odour, making them popular for residential applications.
- Acrylic Sealants: The premium option, offers excellent protection and UV resistance. They’re pricier but worth the investment if you want top-notch results.
Step-By-Step Guide To Applying Seal Coating
Applying seal coating isn’t complicated, but it does require attention to detail. Here’s how it’s done:
1. Mix The Sealant
Sealants can separate in the container, so be sure to mix it thoroughly before applying.
2. Apply The First Coat
For smaller areas, use a squeegee or brush. For larger areas, a spray system can save time and ensure an even coat.
3. Let It Dry
Allow the first coat to dry for at least 4–8 hours, depending on the weather. A rushed job won’t hold up as well, so be patient and wait.
4. Apply A Second Coat
Adding a second coat offers extra protection, especially in high-traffic areas.
5. Curing Time
Wait at least 24 hours before allowing any traffic on the newly sealed surface. It’s tempting to test it out, but patience pays off.
Fun Fact: Did you know that asphalt expands and contracts with temperature changes? That’s why winter is so hard on unprotected asphalt surfaces – all that freezing and thawing puts a lot of stress on the pavement!
Avoid These Common Seal Coating Mistakes
Seal coating may seem straightforward, but a few missteps can make a big difference. Here’s what to avoid:
Sealing Fresh Asphalt
New asphalt needs time to cure – usually 6-12 months. Sealing too soon can lock in oils and prevent proper curing.
Ignoring Repairs
Seal coating isn’t a magic fix for damage. Repair any cracks or potholes first; otherwise, you’ll just end up sealing in the problem.
Not Hiring Professionals
While DIY kits are available, hiring a professional team has its advantages. They use commercial-grade sealants and have the expertise to apply them correctly, ensuring a uniform, long-lasting finish. Plus, they have the right equipment, so the job gets done efficiently.
