DAP Concrete Crack Filler, 1.62 Lb
DAP’s 1.62 lb Concrete Crack Filler provides a water-activated, dry-powder solution for shallow, horizontal cracks in concrete and masonry. It is designed to fill cracks up to 1/2 inch wide and 1/2 inch deep with a single pass, making it suitable for patios, driveways, and interior slabs. The gray shade blends with typical concrete surfaces, reducing visibility after application. The product is especially practical for DIYers seeking a fast, no-mix patch that dries to a workable finish for light foot traffic in a few hours.
Application is straightforward: activate the powder with water, press it into the crack, and allow it to cure. Plan for a 48-hour full cure for heavier use areas or vehicles. Surfaces with higher porosity may require extra material for full coverage. While effective for many horizontal cracks, very wide or shifting cracks may require a different repair approach or professional guidance.
- Repairs horizontal cracks in concrete, stone, and masonry
- Water-activated dry powder; single-pass repair
- Walkable after ~4 hours; full service in ~48 hours
- Gray color blends with typical concrete
DAP Concrete And Mortar Filler
DAP’s Concrete And Mortar Filler and Sealant is a ready-to-use patch filler designed for interior or exterior concrete and masonry. No mixing or additives are required, simplifying projects and reducing setup time. The flexible, low-odor adhesive cleans up easily with water and provides a 24-hour return-to-service time. This makes it a convenient option for quick interior repairs, basements, or porch areas where odor control and cleanup matter.
The product is ideal for small patches of cracks and holes, offering an easy, user-friendly alternative to mixing cements or epoxies. While it excels in non-structural repairs, users should evaluate crack width and movement to ensure the filler remains effective through seasonal changes. For broader structural concerns, consider pairing with a more robust repair method or consulting a professional.
- Seals cracks and holes in interior or exterior concrete
- Ready to use; no mixing or additives
- Flexible adhesive; low odor; water cleanup
- 24-hour return to service time
Magic Crack Filler 2.5Lb Tan
Magic Crack Filler comes in a 2.5-pound tan granulated form designed to fill a wide range of cracks from hairline fractures to larger, more visible gaps. The formula is water-activated, requiring only dampening and water to set, with no mixing or messy preparations. This feature makes it an excellent choice for DIYers seeking a clean, straightforward repair that can restore curb appeal and reduce water intrusion around the crack.
The product is marketed for its ease of use and robust appearance after curing. Once applied, cracks become less noticeable, and the filler helps protect against further water intrusion. While the granulated texture can blend with many concrete finishes, selecting the right color and applying evenly will yield the most seamless finish for driveways, walkways, or patios.
- Fills hairline to larger cracks with a granulated formula
- No-mess, water-activated application
- Resists water intrusion; restores appearance
DAP Liquid Cement Crack Filler, 1 Quart
The DAP 37584 Liquid Cement Crack Filler is a ready-to-use, concrete patch and repair formula designed specifically for horizontal cracks in interior or exterior concrete. Its self-leveling properties help create a smooth, seamless surface that blends gray with most existing concrete. The fast-curing formula allows traffic to resume quickly, with typical readiness for use within 30 to 45 minutes, making it a strong option for time-constrained projects and weekend repairs on driveways and sidewalks.
Use this product on non-structural cracks where additional strength is not required. For larger structural issues or ongoing movement, consider supplementary reinforcement or a different repair approach. Proper surface preparation, including cleaning and ensuring the crack is dry, will improve adhesion and longevity.
- Ready-to-use patch for horizontal cracks
- Self-leveling; gray finish blends with concrete
- Traffic-ready in 30–45 minutes
Autosel Concrete Crack Filler 3-Pack
Autosel offers a three-pack concrete crack filler set designed for small projects. Each pack provides 500 g (approximately 13 oz), with a total of around 39 oz. The product emphasizes elasticity to accommodate ground movement and temperature changes, helping prevent re-cracking after repair. It cures relatively quickly, with a self-leveling behavior that results in a smooth, near-seamless finish.
This value-oriented option is well-suited for homeowners addressing multiple cracks across driveways, patios, walkways, or garage floors. The self-leveling formula reduces the need for extensive tooling, but for best results, ensure proper prep and apply evenly. It’s particularly convenient for quick patches in areas with moderate traffic. For heavier wear zones or structural issues, a more robust solution may be warranted.
- Three packs; 39 oz total for small projects
- High elasticity; resists movement and re-cracking
- Fast-drying, self-leveling finish
