Drying Time
The sealant requires a considerable drying time, sometimes up to three days, before the repaired area can be used.
Application Method

Durability

The Quikrete Gray Polyurethane Self Leveling Concrete Crack Sealant is designed mainly for floor concrete cracks. It comes as a gray polyurethane paste that is waterproof and meets industry standards (ASTM C-920), which means it should hold up well against moisture. Its self-leveling nature helps it settle smoothly into cracks, making application easier and more uniform. The polyurethane formula provides flexibility, which is important for cracks that might expand or contract with temperature changes, helping prevent the filler from breaking apart over time.

Some users have noted a moderate drying time, which might require waiting longer before the repaired area can be walked on or exposed to traffic. The gray color matches typical concrete fairly well but may still be noticeable on certain surfaces, so it might not blend perfectly on all projects.

This product is suited for homeowners or DIYers looking to fix floor cracks in concrete with a reliable, flexible sealant, especially where waterproofing is needed. Those wanting a quick-dry or perfect color match might want to explore other options.

Application Method
Color Match
Durability

Most important from
17 reviews

Application Method
The product works well if it's fresh, but older tubes tend to have large solid chunks that make application difficult or impossible.
Color Match
The formula appears changed from the original, now resembling a silicone caulk that doesn't harden as expected and comes out almost white instead of concrete gray.
Durability
The sealant's texture is thinner and less durable than expected, resembling a latex caulk with gritty particles rather than a firm crack filler.

The Quikrete Gray Acrylic Latex Concrete Crack Sealant 10 oz is a paste-type crack filler, ideal for sealing minor concrete cracks. Its gray color aims to blend well with standard concrete surfaces, though it may not be a perfect match for all shades of concrete. The sealant is designed to be flexible, allowing it to move with the concrete and helping to prevent future cracking. This flexibility makes it suitable for both indoor and outdoor use, where temperature changes can cause expansion and contraction of the concrete.

Application is straightforward, typically requiring a caulking gun, which makes it user-friendly even for those without extensive DIY experience. However, the drying time can vary depending on the crack size and environmental conditions, which may require some patience. One downside is that at 10 fluid ounces, the product may not cover a large area, so multiple tubes might be necessary for extensive repairs. Additionally, the paste form can be a bit messy to work with compared to other types of crack fillers.

In terms of durability, it generally performs well, providing a long-lasting seal that can withstand typical weather conditions. This product is best suited for homeowners looking to perform quick, effective repairs on small cracks in their concrete surfaces.

Buying Guide for the Best Quikrete Concrete Crack Fillers

Choosing the right concrete crack filler is essential for maintaining the integrity and appearance of your concrete surfaces. Whether you're dealing with small hairline cracks or larger gaps, selecting the appropriate product can prevent further damage and extend the life of your concrete. Here are some key specifications to consider when choosing a concrete crack filler, along with explanations to help you make the best choice for your needs.
Type of Crack FillerConcrete crack fillers come in various types, including liquid fillers, caulk-style fillers, and patching compounds. Liquid fillers are easy to apply and are suitable for small, hairline cracks. Caulk-style fillers are ideal for medium-sized cracks and offer flexibility. Patching compounds are best for larger cracks and provide a more durable repair. Choose the type based on the size and nature of the cracks you need to fill.
Drying TimeDrying time refers to how long it takes for the crack filler to set and become fully cured. This is important because it affects how quickly you can use the repaired area. Fast-drying fillers are convenient for quick repairs, while slower-drying options may provide a stronger bond. Consider how soon you need the area to be usable when selecting a filler.
FlexibilityFlexibility is the ability of the crack filler to expand and contract with the concrete as it undergoes temperature changes. This is crucial for preventing the filler from cracking or breaking away over time. Flexible fillers are better for outdoor use where temperature fluctuations are common. If the area you're repairing is exposed to varying temperatures, opt for a flexible filler.
Application MethodThe application method can vary between products, including squeeze bottles, caulk guns, or trowels. The ease of application can impact the quality of the repair. Squeeze bottles and caulk guns are user-friendly and suitable for small to medium cracks, while trowels are better for larger repairs. Choose a method that you are comfortable with and that suits the size of the cracks.
Color MatchColor match refers to how well the filler blends with the existing concrete. This is important for aesthetic reasons, especially if the repair is in a visible area. Some fillers come in a variety of colors or can be painted over once dry. If appearance is a concern, look for a filler that closely matches your concrete or can be easily painted.
DurabilityDurability is the ability of the crack filler to withstand wear and tear over time. This is important for ensuring a long-lasting repair. Durable fillers are typically more resistant to weather, chemicals, and physical impact. If the area you're repairing is subject to heavy use or harsh conditions, choose a filler known for its durability.
