We'll also cover the different types of crack fillers available and how to choose the right one for your needs.
Sikaflex self-leveling sealant is one of the best products for filling small cracks in concrete. This product comes in 10-ounce containers that fit standard caulking guns and can fill spaces up to 1½ inches wide on horizontal surfaces such as floors, hallways and patios. Once fully cured, it remains flexible and completely submersible, making it suitable for repairs to swimming pools or other areas exposed to water. It simply squeezes the product into the crack and, thanks to its self-leveling quality, little or no tool work will be needed to obtain a uniform finish.
Fully cured Sikaflex can be painted, stained or sanded to the desired user finish. For larger cracks or areas with a lack of material, Red Devil's 0644 Pre-Mixed Concrete Patch is a great option. This product comes in a 1 quart tub and is pre-mixed and ready to use. It can fill large cracks, deep depressions, or areas with a lack of material with ease.
Damtite concrete superpatch repair is another great option for fixing large cracks in concrete. This waterproof patching compound uses a unique, shrink-free formula that can be applied to concrete surfaces in layers from 1 inch thick, up to 3 inches thick. This patch kit comes with 6 pounds of patch powder and 1 pint of liquid additive, so users can mix as much or as little as needed to apply patches or coat concrete surfaces. For those who prefer water-based crack fillers, Red Devil 0644 1 quart ready-mix concrete patch and Damtite 04012 gray adhesive vinyl concrete patch are a good choice. Bluestar Flexible Concrete Crack Filler (Light Gray) is also an excellent preventive measure for those with minimal cracks to prevent them from getting worse.
Akona Grey Pourable Concrete Crack Filler is a liquid filler that is fantastic for those who want a convenient solution for their range of different concrete cracks. When performing crack repairs in concrete, you should always use an epoxy, polyurethane, or polyurea crack repair product that can be sanded. They will cure and harden with greater strength than concrete. During the process of milling a crack, the contractor often uses a grinder to make a V-shaped trench, with the stroke centered on the trench. This line of lower strength encourages the cracks to follow along the bottom of the groove or cut instead of wandering the surface. In conclusion, Sikaflex self-leveling sealant is the best overall concrete crack filler you can buy right now.
It's easy to use and works indoors and outdoors in a variety of crack sizes.
