The DAP 7079860500 Concrete Crack Filler is designed to fix horizontal cracks in concrete, stone, and similar materials. It handles cracks up to half an inch wide and deep in just one step, making it suitable for common household or driveway cracks. Its powder form activates with water, so there’s no mixing hassle—just prep, fill, and spray. It becomes strong enough for light foot traffic within 4 hours and can fully support vehicles after 48 hours.

This product resists shrinkage, cracking, and fading from sunlight, which means repairs should stay intact and look good over time. It’s waterproof and made with an advanced acrylic polymer, improving durability. On the downside, it’s limited to horizontal cracks and a maximum crack width of 1/2 inch, so it may not be the best choice for larger or vertical cracks. Also, while it sets quickly for light use, full strength takes two days, so patience is required before heavy use.

For those needing a straightforward, reliable repair for typical small cracks on horizontal surfaces, this filler provides a practical and effective solution.

Buying Guide for the Best Concrete Crack Repair Products

When it comes to repairing cracks in concrete, choosing the right product is crucial to ensure durability and effectiveness. The right product will depend on the type of crack, its size, and the conditions it will be exposed to. Understanding the key specifications of concrete crack repair products will help you make an informed decision and achieve the best results for your specific needs.
Type of CrackThe type of crack you are dealing with is important because different products are designed for different types of cracks. Hairline cracks, structural cracks, and expansion cracks all require different approaches. Hairline cracks are usually superficial and can be repaired with simple fillers, while structural cracks may need more robust solutions like epoxy injections. Expansion cracks, which occur due to temperature changes, might require flexible sealants. Identifying the type of crack will guide you to the appropriate product.
Crack WidthThe width of the crack is a critical factor in selecting a repair product. Narrow cracks (less than 1/8 inch) can often be repaired with liquid fillers or sealants, while wider cracks (greater than 1/8 inch) may require more substantial materials like patching compounds or epoxy. For very wide cracks, you might need to use a combination of products to fill and seal the crack effectively. Measure the width of the crack to determine the best product for your repair.
Application MethodDifferent products have different application methods, such as caulking, injecting, or troweling. Caulking is typically used for smaller cracks and is easy to apply with a caulking gun. Injection methods are used for deeper or structural cracks and require specialized equipment. Troweling is used for surface repairs and involves spreading the product over the crack with a trowel. Consider your comfort level with these methods and the tools you have available when choosing a product.
Curing TimeCuring time refers to the amount of time it takes for the repair product to fully harden and become effective. Some products cure quickly, within a few hours, while others may take several days. If you need a quick fix, look for products with shorter curing times. However, for more permanent repairs, a longer curing time might be necessary to ensure the product sets properly and provides a durable solution. Match the curing time with your project timeline and urgency.
FlexibilityFlexibility is important for cracks that are likely to expand and contract due to temperature changes or structural movement. Flexible repair products, such as certain sealants, can accommodate these movements without cracking themselves. If the area where the crack is located experiences significant temperature fluctuations or movement, opt for a flexible product to ensure a long-lasting repair. For static cracks, a rigid product may be sufficient.
DurabilityDurability refers to how well the repair product can withstand environmental conditions and wear over time. Products designed for outdoor use need to be resistant to UV rays, moisture, and temperature changes. Indoor products may not require the same level of durability. Consider the location of the crack and the conditions it will be exposed to when selecting a product. A durable product will ensure that the repair lasts and does not need to be redone frequently.
