Driveway Paver Sealing: Everything You Need to Know

Why Driveways Take the Most Abuse

Your paver driveway works harder than any other surface on your property. Every day it bears the weight of vehicles — often 3,000 to 6,000 pounds or more — transferring that load directly to the paver surface. Oil drips, tire scuff marks, and brake fluid spills accumulate over months. And unlike your patio or pool deck, your driveway sits in full sun from morning to afternoon, absorbing maximum UV radiation every single day.

Arizona's climate makes this worse. Pavement surface temperatures in Phoenix regularly exceed 160°F in summer, accelerating the breakdown of both the paver material and any sealer protecting it. Asphalt driveways crack and soften under these conditions — which is a big reason why pavers are the preferred choice in Metro Phoenix. But pavers without sealer are still vulnerable. The sealer is what stands between your investment and years of UV damage, oil saturation, and color loss.

What Driveway Sealing Protects Against

A properly applied sealer forms a protective barrier across the entire paver surface. For driveways specifically, that barrier defends against:

• Oil stains — Motor oil, transmission fluid, and brake fluid can permanently stain unsealed pavers. Once they penetrate the porous surface, they bond with the material and no cleaner will fully remove them. Sealer keeps oil on the surface where it can be wiped away.
• Tire scuff marks — The rubber compounds in tires leave black marks on unsealed pavers. Sealer makes these marks surface-level and removable.
• UV fading and color loss — The most visible form of driveway damage over time. Sealer absorbs UV before it reaches the paver's pigment layer.
• Water infiltration and monsoon damage — Arizona monsoons can dump significant rainfall in short bursts. Unsealed driveways absorb that water, which then migrates to the base, softening the substrate and causing settling.
• Chemical spills — Pool chemicals stored in the garage, fertilizers, and cleaning products can etch or stain unsealed concrete pavers. Sealer provides a chemical-resistant surface layer.

Driveway-Specific Sealer Choices

Not every sealer is right for driveway use. The demands of vehicle traffic and chemical exposure require a more durable product than what works fine on a backyard patio.

Solvent-based sealers are generally recommended for driveways. They penetrate deeper into the paver, create a stronger bond, and hold up better against oil, chemicals, and the heat cycles driveways experience. They also tend to last longer under vehicle traffic than water-based alternatives.

For finish, most homeowners choose semi-gloss or wet-look sealers for their driveways. The enhanced sheen dramatically improves curb appeal — the color looks saturated and rich, and the surface has a finished, intentional look that matte sealers do not provide.

One addition worth discussing with your contractor: anti-skid additives for the apron section near the street. This is the entry point where tires transition from asphalt to paver, and where wet surfaces create the most slip risk. A fine aggregate mixed into the sealer provides grip without changing the appearance significantly.

How Long Does Driveway Sealing Last?

Expect 2–3 years from a professional driveway sealing job in Arizona under normal conditions. Several factors shorten that window:

• Heavy vehicle use — Multiple vehicles, trucks, or daily motorcycle parking accelerate wear in the tire path zones
• Extreme heat seasons — Consecutive summers above 115°F break down sealer faster than in milder climates
• Chemical exposure — Frequent oil drips or chemical spills that are not cleaned promptly degrade the sealer surface
• Sealer quality — Commercial-grade sealers with higher solids content outlast box-store products significantly

When the sealer begins to wear, it typically fails first in the tire path — two parallel strips that fade and lose sheen while the rest of the driveway still looks sealed. That is your cue to schedule a reseal before the bare spots allow oil penetration.

The Prep Step That Matters Most for Driveways

Every paver sealing job requires thorough preparation, but driveways have one step that is non-negotiable: degreasing.

Oil stains must be treated with a dedicated degreaser before any washing begins. Here is why this sequence matters: if you pressure wash first, you drive the oil deeper into the paver's pores. The surface looks cleaner, but the oil is now trapped further in. Then when sealer is applied, the sealer bonds on top while the oil stain remains locked underneath — visible as a dark shadow beneath the sealed surface that never goes away.

The correct process is degreaser first, agitation to lift the oil, then pressure washing to remove both the degreaser and the loosened oil together. For driveways with significant oil history, multiple degreaser applications may be needed before the surface is clean enough to seal.

Cost for Driveway Sealing

Driveway sealing costs are based primarily on square footage, plus any additional prep work required. Typical ranges in Metro Phoenix:

• Single car driveway (approximately 300–400 sq ft): $250–$400
• Two-car driveway (approximately 500–700 sq ft): $350–$600
• Large or circle driveway (800 sq ft and up): $600–$1,200

These estimates assume standard prep. Driveways requiring oil degreasing, efflorescence treatment, or joint sand replacement before sealing will have additional costs for those services. A free quote from Go Go Gloss includes a full assessment of prep needs so there are no surprises on job day.

Most homeowners find that sealing their driveway every 2–3 years is far less expensive than replacing pavers damaged by oil penetration or structural failure from unsealed joint sand — paver replacement runs $15–$25 per square foot installed.
