When it comes to repairing cracks in concrete, there are a variety of solutions available. For larger cracks, quick-setting concrete or a patch compound may be the best choice. A standard concrete mix could also do the job, and you can mix everything you need to fill the crack. Finishing with a rejuvenator can help hide the repair and add more strength.
For smaller cracks and occasional use, the self-leveling concrete sealant 3.0 from DAP is ideal because it dries quickly and offers a fine point for the product to fill those smaller openings effortlessly. It is also self-leveling, which means you won't have to worry about leveling it before drying it. Offers exterior protection and resistance to moisture build-up and dries to a neutral gray color. The Red Devil Premixed Concrete Patch squeeze tube is a convenient and easy-to-use concrete crack filler that fits in your pocket and serves as the daily crack repair tool for small but deep cracks. Consistency is not too runny or too dry, which means it is easy to patch horizontal and vertical cracks.

Apart from that, I also mentioned earlier the CRACK STIX Concrete Joint Crack Filler &%, which is a different type due to its solid form. This might appeal to you if you have a torch in your arsenal of tools to activate and melt the material in the concrete crack (s).In addition, there are also types that require heating with a torch, and types that require the use of a caulking gun. Sometimes the gun comes with the set, as is the case with the Applied Technologies concrete foundation crack repair kit. Flexible sealants are the best solution for concrete cracks subjected to continuous slab movement.
This is because they still work when there are concrete changes. The PLI-STIX Dalton Latex-ITE is ideal for filling and repairing wider cracks in concrete (or asphalt) surfaces.

This Sikaflex self-leveling sealant does not require tools to level, making it convenient for quick repairs of cracks that you can set up and forget.
Surprisingly, it can cover gaps up to 1.5 inches wide, thanks to the ability to lay layers of sealant. The only downside is that it only comes in 10 oz bottles, so while it is cheap to buy an individual bottle, costs can increase if you have to tackle more significant patch work. It works well by withstanding up to 3,050 pounds of hydrostatic pressure and prevents water from flowing, even under pressure. The only drawback of this product is that you have to mix it yourself because it comes in powder form. It is also less convenient to apply compared to point-shaped bottles.
It is easy to mix, has little odor and does not contain solvents. Rust-oleum is so confident that they claim that this 2-part epoxy is harder than concrete and adheres to any concrete surface.

It is easy to use; you get greater control of the filler and the precise nozzle allows you to reach tight spots. This particular canister only weighs 100 oz, so it is best suited for smaller repairs, but you can buy it in packs of 6 or as a squeeze bottle with a conical spout. Does not shrink or crack and can be painted and sanded. Dries light grey and is perfect for repairs around window frames and doors and pipes. It takes longer to heal than most of the products presented so far.

Comes in a 1 US gallon container and covers 160 linear feet, with cracks 0.25 inches deep and 0.25 inches wide.

You don't need any tools to apply this solution; it has a conical nozzle that helps point where you're going. It can also be painted, so if you have a painted garage floor, you can mix the colors to match.
The only downside is that it is not suitable for vertical applications and, despite coming in a 16 oz bottle, coverage is quite scarce for the price. It also has a cure time of 24 hours, which is not unusual, but since you apply it in layers, it is 24 hours per layer. Concrete can be repaired using various methods depending on its condition; however there are some solutions that stand out from others due their ease of use or effectiveness when tackling different types of cracks or holes. For larger cracks or holes quick setting concrete or patch compounds may be your best bet as they offer strength while drying quickly; while self leveling sealants such as DAP 3.0 offer an easy way of filling smaller openings with precision due their fine point applicator. For more serious repairs Red Devil premixed concrete patch squeeze tube or Bluestar flexible concrete crack filler may be necessary as they offer greater coverage while being able to withstand greater pressure; while Rustoleum 2 part epoxy offers an incredibly strong solution when dealing with larger holes or deep cracks. Finally Akona pourable padding offers an easy way of filling large gaps up 1 inch wide while being able to match existing colors due its light or dark gray options; however its coverage may be limited due its 16 oz bottle size. No matter what type of repair needs doing there will always be an appropriate solution available; however if unsure always consult an expert before attempting any repairs yourself.
