Sealcoating vs. DIY Asphalt Kits - Why Professional Service Wins in Eugene
Does a DIY asphalt kit really hold up in rainy Northwest conditions?
In Eugene, asphalt surfaces face constant moisture, seasonal temperature changes, and freeze-thaw cycles. When driveways or parking lots begin to fade or crack, DIY sealcoating kits often look like an easy solution. Unfortunately, many of these products are not designed to withstand prolonged moisture exposure or Oregon weather patterns.
Professional sealcoating is about more than appearance. It is a critical step in protecting asphalt from water intrusion and structural breakdown.
Why Eugene asphalt needs proper sealing
Moisture is the biggest enemy of asphalt in the Pacific Northwest. Rainwater penetrates small cracks, weakens the base, and expands during colder temperatures. Over time, this leads to cracking, potholes, and surface failure.
Sealcoating helps block moisture penetration and slows oxidation, giving asphalt a longer service life in wet conditions.
The problem with DIY asphalt sealcoating kits
DIY kits are typically thin and inconsistent, offering minimal protection against constant moisture. They also rely heavily on ideal weather conditions that are difficult to achieve in Eugene.
Common issues include:
• Poor adhesion due to damp surfaces
• Inadequate crack filling
• Uneven coverage
• Short curing windows easily disrupted by rain
• Rapid wear from water exposure
Many DIY applications fail within months when exposed to Oregon rainfall.
Why professional sealcoating performs better
Professional contractors use commercial-grade sealcoating products designed to resist moisture and temperature changes. Just as important is proper timing and surface preparation.
At Seal It Up!, projects are scheduled around weather conditions and include thorough cleaning, crack sealing, and controlled application. This ensures the sealcoat cures correctly and bonds to the asphalt.
Professional service provides:
• Better moisture resistance
• Longer-lasting protection
• Uniform appearance
• Reduced risk of premature failure
DIY sealcoating can create bigger problems
Improperly applied sealcoat can trap moisture beneath the surface, accelerating damage rather than preventing it. Once water is sealed into cracks, deterioration speeds up.
Long-term risks include:
• Increased cracking and surface breakdown
• Peeling or flaking coatings
• Higher repair costs
• Reduced pavement lifespan
What seems like a budget solution often becomes an expensive mistake.
When DIY sealcoating is not a good idea
DIY kits should be avoided for:
•
Driveways with existing cracks
• Parking lots or shared access areas
• Asphalt exposed to frequent rain
• Properties requiring consistent appearance
In these situations, professional service is the safer and more cost-effective option.
What a professional sealcoating service includes
A complete sealcoating service typically involves:
• Deep cleaning and preparation
• Crack repair and sealing
• Application of commercial-grade sealcoat
• Proper curing time
• Striping or markings if needed
This process protects the asphalt structurally, not just visually.
