7 Best Concrete Crack Fillers of 2024

This Sikaflex self-leveling sealant requires zero tooling to level, making it convenient for fast crack repairs that you can set and forget about. Surprisingly, it can bridge gaps up to 1.5 inches in width, thanks to the ability to layer up the sealant.

Once set, it is paintable, sandable, and stainable, so if you are using it for filling gaps in walls, you can match it in and make the gap disappear.

Once it cures, it is flexible and durable, so it withstands whatever you throw at it. It’s also water and weatherproof, so once you fill the gap, you don’t need to keep one eye on the weather in case it rains.

The only downside is it only comes in 10 oz bottles, so while it is cheap buying an individual bottle, the costs may escalate if you have a more significant patch job to tackle.

This Drylok hydraulic cement is pretty unique because, unlike standard cement that hates moisture, this stuff sets even underwater. The water starts a chemical reaction that causes the concrete to set hard.

It makes it the ideal product for your pool repairs. It anchors metal to masonry, so if you are resetting the pool ladder to the wall, this filler does the job. It also sets in 3 to 5 minutes, which is super-fast.

It performs well by withstanding up to 3,050 pounds of hydrostatic pressure and stops water from flowing, even when under pressure. The only downside with this product is you have to mix it yourself because it comes in powder form. It is also less convenient to apply compared to pinpoint bottles.

However, you do get more coverage, enabling you to repair larger gaps and holes.

This epoxy formula is guaranteed not to shrink or crack and bonds to walls and floors. It fills cracks up to 0.5 inches, so it is ideal for smaller repairs like window and door frames. It mixes to a consistency similar to plaster and cement, so it handles easily when working vertically.

It’s simple to mix, low odor, and solvent-free. Rust-oleum is so confident they claim this 2-part epoxy is harder than concrete and bonds to any cement surface. You can use it indoors and outdoors, so it is ideal for general repairs.

This filler dries in 8 hours, so it does take a little longer to cure, and you do have to mix it yourself, so it is less convenient to apply than other fillers. The other downside is the price. It costs a lot more than the previous products to feature, but you might be paying for the famous Rust-oleum name.

Sometimes you get larger cracks and holes in your concrete. You’d think a filler with a pinpoint nozzle would struggle to cope, but this Sashco filler does exactly that. It handles 3-inch spans.

It’s pre-mixed and comes in 10.5 fluid oz bottles, so it is better for small repair patches. It’s easy to use; you get greater control of the filler, and pinpoint nozzle enables you to reach tight spots.

It’s freeze-to-thaw resilient, paintable, and while the company doesn’t state the curing time, some have reported it takes days rather than hours. This filler withstands foot and vehicle traffic, so if you need a crack fixing on your driveway, this material can cope.

In fact, it works on most surfaces, from garage floors and patios to sidewalks and basement floors. It even competes with Rust-Oleum for vertical applications.

Like the Sikaflex, you only get small bottles, so if you have large-scale repairs, you might want to invest in another product. However, for small patches or wide gaps, this flexible filler does the job.

This Red Devil pre-mixed concrete filler is the ideal product to use when you want to save time mixing a solution to carry out repairs. It has a thick consistency, making it perform like plaster or cement, and is applied using a flat blade scraper or putty knife.

This particular pot is only 100 oz, so it is better suited to smaller repairs, but you can buy it in packs of 6 or as a squeezable bottle with a tapered nozzle. It won’t shrink or crack and is paintable and sandable.

It dries a light gray and is perfect for performing repairs around window and door frames and pipework. It takes longer to cure than most products featured so far. Once you’ve filled the hole, you should wait 24 to 48 hours before sanding and painting.

Also, it is not suitable for vehicle traffic, so don’t use it on your driveway.

This Akona pourable filler is the ultimate in convenience. It comes in a 1-US gallon container and covers 160 linear feet, with cracks 0.25 inches deep and 0.25 inches wide.

You can use it on your driveway because it can take the weight of car traffic, but it is also useful for filling gaps in garage floors, patios, sidewalks, and slabs. It is not suitable for vertical applications because the consistency is too runny.

When you apply this product, you need to make sure the temperature is right. It air dries, so using it in cooler temperatures delays the curing process. If it’s above 50 degrees Fahrenheit, you should be fine.

The drying times range between 30 and 60 minutes, but if you want it to set really hard, allow 24 hours. This Akona is expensive. It costs multiple times the price of other fillers.

This concrete crack filler is the perfect choice for filling holes and cracks in garage floors. It is pourable, much like the Akona, and when it dries, it retains its flexibility to adapt to the future movement of the crack.

You don’t need to worry about extreme swings in the temperature because it stays flexible no matter what.

It comes in light and darker gray, so you should be able to color-match, and it fills gaps up to 1-inch wide. You don’t need any tools to apply this solution; it has a tapered nozzle that helps to target where it goes.

It is paintable too, so if you have a painted garage floor, you can blend the colors to match. The only downside is it isn’t suitable for vertical applications, and despite coming in a 16 oz bottle, the coverage is pretty meager for the price.

It also has a 24 hour curing time, which isn’t unusual but given you apply it in layers, that’s 24 hours per layer.
