EWT Premium Hot-Filler 50 Ft
This hot-fill product targets long cracks and joints in parking lots, delivering a 3mm thick seal for durability. It uses rubberized asphalt strip materials that create a strong, waterproof bond suitable for immediate top coating. The formulation is designed for easy handling, helping contractors apply seals efficiently along extensive crack runs.
- 3mm extra thickness for added durability
- Easy to work with
- Rubberized asphalt strip materials; crack filler
- Waterproof seal can be immediately top coated with seal coating
Best applied on clean, dry surfaces; follow heating and application guidelines for hot-applied products. Plan for appropriate heating equipment and safety precautions. This option works well for large parking areas needing a robust, long-lasting seal before sealcoating or further maintenance.
EWT Premium Tape 2in x 50 Ft
This self-adhesive rubberized asphalt tape provides a quick option for repairing medium cracks and joints. The tape is designed with a 3mm thickness and sticks to asphalt surfaces, allowing for rapid repair work that can be followed by seal coats if needed. Its flexible composition helps accommodate minor ground movement without immediate re-cracking.
- 3mm thick, self-adhesive tape
- Fast, DIY-friendly crack repair
- Flexible and weather-tolerant
- Compatible with subsequent seal coating
Ideal for quick repairs during milder weather and smaller cracks. Surface prep—clean, dry spots—improves adhesion, and proper tension during application helps ensure the tape sits flat across the crack line. Not a substitute for very wide or structural cracks, but excellent for speed and convenience on traffic aisles.
GoldStar Cold Pour Crack Filler
GoldStar’s Cold Pour Crack Filler is a ready-to-use solution designed for driveways, parking lots, and roads. It seals cracks to reduce water intrusion and deterioration. The product is quick and straightforward to use, though it requires thorough mixing before application to ensure consistent adhesion and performance across the crack line.
- Enhances the integrity of asphalt and sub-grade
- Seals existing cracks from deterioration and costly repairs
- Quick and easy to use; must be mixed thoroughly before use
- Suitable for medium to smaller cracks in various climates
Best for smaller to medium cracks and routine maintenance. This option provides a fast, low-luss solution for crack repair, with the caveat that larger, deeper, or highly trafficked cracks may require more substantial fillers or multi-step repair. Proper surface prep and curing time improve long-term performance.
Asphalt Kingdom Crack Sealer
This large-scale crack sealing kit is designed for parking lots and driveways, packaged as 36 boxes totaling 1,080 pounds. The sealer uses a melt-and-apply method and typically dries within about 30 minutes, enabling turnarounds with minimal disruption to traffic. It’s a practical option for substantial crack repair projects and new crack seals in commercial properties.
- Permanent bond on asphalt, concrete, or masonry surfaces
- Self-adhering or melt-and-apply options available
- Waterproof seal that dries quickly (about 30 minutes)
- All-season performance suitable for parking lots and roads
Designed for large projects, this kit suits facility managers tackling extensive crack repairs across sizeable lots. When using melt-and-apply formulations, ensure proper heating, ventilation, and safety protocols. Plan for downtime during cure and consider coordinating with sealcoat applications for best results.
Blue Star Flexible Crack Filler
Blue Star’s flexible crack filler is a DIY-friendly option that remains flexible through hot and cold weather. It’s designed to fill cracks up to 1 inch wide and is easy to apply with basic tools. The flexible formulation helps accommodate movement caused by temperature changes and minor substrate shifts, reducing the risk of re-cracking.
- DIY-friendly, no special tools required
- Remains flexible in hot and cold weather
- Fills cracks up to 1 inch wide
Best for small-to-medium cracks and hands-on projects. While convenient for do-it-yourself repairs, it may not be the ideal choice for very wide or deep cracks in high-traffic areas. Surface prep—clean, dry surfaces—improves adhesion and effectiveness, especially in busy parking lots.
Buying Guide
Key Considerations
- Crack type and size: For long or wide cracks, hot-fill or tape-based solutions provide stronger adhesion and longer-lasting results. Narrow cracks can often be addressed with cold-pour fillers or flexible tapes.
- Surface condition: Ensure pavement is clean, dry, and free of standing water before applying any filler or sealer. Wet surfaces reduce adhesion and curing quality.
- Product type: Crack fillers (used for cracks) versus surface sealers (used to seal the entire pavement surface). Some products combine both functions, depending on the formula.
- Cure time and traffic: Quick-drying formulas reduce downtime but may have limitations on traffic exposure during curing. Plan around business hours and temperature.
- Climate and weather: Flexible, rubberized materials perform better in freeze-thaw climates. Hot-applied products require safe handling in high temperatures.
- Application method: Sprayer, squeegee, melt-and-apply, or self-adhesive tapes—choose based on project size and access to equipment.
- Coverage and yield: Check the product’s coverage rate to estimate how many gallons or pounds are needed for your lot area.
- Topcoat compatibility: Some products allow immediate top coating after curing; others require a waiting period or specific seal coatings.
- Safety and VOCs: Consider products with lower volatile organic compounds and clear safety guidelines for heating or applying near vehicles and pedestrians.
- Budget and maintenance: Large-scale projects may justify bulk purchases or kits, while DIY repairs may be better suited to smaller, readily available products.
Choosing the Right Product for Your Parking Lot
- For extensive crack runs and heavy traffic: Lean toward hot-fill fillers or large sealer kits that provide durable, long-lasting seals and allow top coating after curing.
- For large-area seal coating with quick turn-around: Consider emulsions or fast-dry sealers designed for parking lots with minimal downtime.
- For DIY small repairs: Flexible crack fillers and self-adhesive tapes offer fast, easy fixes without specialized equipment.
- Climate-driven choices: In freeze-thaw areas, select rubberized, flexible formulations to accommodate movement and reduce re-cracking.
