10 Best Asphalt Crack Fillers 2025 in the United States

Crack Stix Blacktop Crack Repair is a rubber-based crack filler designed for sealing narrow cracks (about 1/4 inch) in asphalt surfaces. Its compact stick format makes it easy to apply directly onto cracks, without the need for special tools or heating, which suits users looking for a simple, do-it-yourself solution.

The rubber material provides some flexibility, allowing the repair to expand and contract with temperature changes, helping to prevent further cracking. Crack Stix products typically harden quickly and perform best in temperatures above 50°F, making them less ideal for very cold conditions. Durability is generally good for small cracks, but for larger or deep cracks, this product may not offer a long-term fix.

The application method is straightforward, but the small stick size means it’s best for repairing limited areas rather than large surfaces. This product is a convenient choice for homeowners or DIYers who want a quick, easy way to fill minor blacktop cracks and extend the life of their pavement without professional help.

The LUVBOATE Asphalt Crack Filler is a flexible, self-leveling sealant designed to repair a variety of cracks in driveways, sidewalks, patios, and other surfaces like concrete, brick, and metal. It uses a high-elasticity formula that adapts well to movement and settlement in the ground, which helps prevent cracks from reopening. This flexibility makes it a good choice for areas with frequent traffic or temperature changes. The filler is waterproof once cured, providing a strong barrier against water and preventing further damage from leaks or moisture.

Application is straightforward: clean and dry the crack, then inject the filler using the nozzle, which self-levels for a smooth finish. It dries relatively quickly, curing fully in about 24 to 48 hours, saving time compared to products that take longer. Another advantage is its durability and resistance to UV rays and extreme weather, meaning it should hold up well over time without needing frequent repairs.

A limitation to consider is that the filler may be less effective if applied in very cold or extremely hot conditions, and very large or deep cracks might require additional preparation or multiple applications. For typical driveway and walkway cracks, this filler provides a reliable and user-friendly solution that balances flexibility, adhesion, and waterproofing.

The GoldStar Asphalt Cold Pour Crack Filler is a ready-to-use polyurethane-based sealer designed for filling shallow cracks in asphalt, specifically those between 1/4" to 1/2" wide. It’s water resistant, which helps protect your pavement from water damage and further deterioration. Being a cold pour product means you don’t need special heating equipment—just mix it well before applying, making it convenient for DIY driveway or parking lot repairs.

This product is best for minor cracks rather than deep or very wide ones, so it’s ideal if your pavement issues are mostly surface-level. It helps maintain the asphalt’s integrity and reduces the appearance of cracks, potentially saving you from more expensive repairs down the line. The product requires thorough mixing before use, which is important to ensure proper performance.

At 5 gallons and weighing over 40 pounds, it’s a substantial amount that suits medium-sized repair jobs well. If you’re looking for a heavy-duty, easy-to-apply solution for small to medium cracks in asphalt, this GoldStar filler is a solid choice, though for larger or more flexible cracks, you might need a different product.
