5 Best Asphalt Crack Fillers: Quick Reference Chart

These five products represent the best options for different repair scenarios, from minor driveway cracks to commercial parking lot maintenance. The right crack filler will save you from costly repaving down the road.

1. Crack-Stix: Best for Permanent Commercial-Grade Repairs

Crack-Stix delivers a lifetime-guaranteed solution originally formulated for highway repairs. This rubberized asphalt crack filler comes in rope form that you melt directly into cracks for a permanent seal that expands and contracts with temperature changes.

The product bonds at the molecular level with existing asphalt, creating a waterproof seal that won't pull away or crack. During testing, Crack-Stix filled cracks completely in about 30 minutes and maintained flexibility through freeze-thaw cycles.

Key features

• Melt-in rope design: Simply press the rope into cracks and apply heat with a torch for complete adhesion
• Lifetime guarantee: The only crack filler offering a permanent repair warranty for both asphalt and concrete
• No VOC emissions: Safe for residential use with no harmful fumes during application

Pros

• Creates permanent repairs that last as long as the surrounding pavement
• Works in temperatures from 32°F without losing adhesion (ground temperature above 40°F)
• Available in multiple sizes (125 ft medium or 250 ft small) for different crack widths

Cons

• Requires direct heat (e.g., propane torch or heat gun) for application
• Higher upfront cost than liquid fillers
• May be too large for hairline cracks under 1/4 inch

Pricing: Around $89.49 directly from Crack-Stix with free domestic shipping

Bottom line

Crack-Stix earns top marks for contractors who want one-and-done repairs. The torch requirement and $89.49 price make it overkill for small residential jobs, but for commercial properties or homeowners tired of annual crack filling, it's worth the investment.

FAQs

1. What's the difference between crack filler and crack sealer?

The difference between crack filler and crack sealer lies in flexibility and intended use. Crack fillers are rigid materials designed for non-working cracks that don't experience movement, whereas crack sealers remain flexible to accommodate pavement expansion and contraction. For filling cracks in asphalt driveways, parking lots, and roads, crack sealer works by filling the crack with a flexible material that adheres to the asphalt and prevents water from seeping in.

2. How long does asphalt crack filler last?

Asphalt crack filler typically lasts 1 to 3 years for standard products, though premium options offer longer protection. Hot pour rubberized crack sealer can be used to fill cracks up to 1" in width and allows contractors to save money on asphalt maintenance supplies. Products like Crack-Stix offer lifetime guarantees, and budget options may need annual reapplication depending on climate and traffic conditions.

3. What's the best crack filler for driveways?

The best asphalt driveway crack filler depends on your specific needs and crack size. For sealing multiple cracks over a large section of a driveway, Latex-ite's asphalt-based sealant can cover 300 to 500 square feet and incorporates sand for a skid-free, high-traction surface. For permanent repairs, Crack-Stix offers commercial-grade durability, while Red Devil 0637 provides excellent value for annual maintenance.

4. What's the difference between blacktop and asphalt crack filler?

There's no functional difference between blacktop and asphalt crack filler. They're the same product with regional naming variations. Both terms describe sealants designed for repairing cracks in asphalt pavement, whether it's called blacktop, asphalt, or tarmac. The best blacktop crack filler works identically to asphalt crack filler.

5. What's the best time of year to apply asphalt crack filler?

The best time to apply asphalt crack filler is during moderate temperatures between 50°F and 85°F. Most asphalt fillers require application when air, material, and surface temperatures are between 50 and 90°F, with no rain forecasted for 48 hours. Spring and fall typically offer ideal conditions, though products like QPR and Liquid Rubber work in extreme temperatures from below freezing to over 100°F.
