Does Flex Seal Work on Concrete Cracks? Beginners Guide
The most general type of concrete issues that may occur on driveways, patios, or even walls are cracks. If you are searching for a fast and efficient method of sealing these cracks, you may have heard of Flex Seal. But does it really work on the concrete cracks? So let’s do the math and find out whether this popular product is what you need.
What Is Flex Seal?
Flex Seal is a rubberized material that can be obtained in liquid form, aerosol, or in the form of tape. It is intended to form a protective layer on surfaces in order to prevent water seepage. Most people apply it in home repairs such as fixing leaks and cracks at various places in a house and on various materials such as wood, metal and concrete.
Is It Possible to Use Flex Seal on Concrete?
Yes, Flex Seal is suitable to be applied on cracks in concrete. This is good for sealing small to medium cracks and is particularly useful where the cracks are exposed to moisture. The rubberized coating forms a barrier that does not allow water to penetrate in the cracks and this can help to prevent further deterioration.
For professional repairs or severe damage, it’s better to consult experts like those at Speedway Concrete Corp or explore specialized services such as concrete foundation repairs or masonry contractors in Brooklyn.
How to Apply Flex Seal on Concrete Cracks
If you decide to use Flex Seal for your concrete cracks, follow these steps to get the best results:
- Clean the Area: Initially, you should make sure that the crack is clean as well as the area that adjoins it. Scrape off the surface with a wire brush or vacuum to get rid of any dirt, debris, and weak concrete. Flex Seal needs to be applied to a dry surface and always remember to do so.
- Choose the Right Product: Flex Seal is accessible in a spray, liquid and as a tape. For cracks, it is recommended to use the liquid or spray type. The spray is particularly useful for the areas that are hard to reach while the liquid form is somewhat more accurate.
- Apply the Product: If you are using the liquid version, then you should pour it directly into the crack and use a brush or a putty knife to spread it across the crack. For the spray version, aim the can at the surface and apply it at a distance of 8-12 inches and spray it evenly. Make sure you cover the whole crack.
- Allow It to Dry: Flex Seal needs time to cure. It is ideal for you to wait until it dries up so that you do not expose it to water or have many people walking on it. In case you have some specific instructions on the size of the crack and the type of Flex Seal used, you have to check the product’s instructions for the drying time.
- Reapply If Needed: For wider gaps, there is a possibility that you will have to use several coats of Flex Seal. Make sure to allow each layer to dry before applying the next layer.

Flex Seal and Its Limitations When Applied on Concrete
While Flex Seal can be a great option for certain repairs, it does have its limitations:
Not for Structural Cracks: The best suited for small cracks is the Flex Seal. Wide cracks should be repaired by a professional and involve the use of sturdier material than that used in the small ones.
Durability: It may not last long in areas of high traffic or usage, or when put under much pressure.
Surface Preparation: Preparation and cleaning are very important. If this step is neglected, then the adhesion that is formed is likely to be very poor.
Aesthetic Finish: Unlike other sealers, Flex Seal may not produce a perfect match with the concrete surface and may appear as a patch.
For more durable or cosmetic solutions, consider using professional paver stone installations or concrete steps.
When to Use Flex Seal vs. Other Solutions
Flex Seal is best for minor cracks that require a quick solution and a waterproofing solution. But where there are big or even structural cracks, it is advisable to use concrete repair products. These are intended to adhere to the concrete and give it long-term durability.
You may also need help with surrounding elements like granite services or blacktop services depending on the property type.
Conclusion
Flex Seal can be used to treat concrete cracks and for minor repairs, the results can be impressive. It is very basic and can be used for waterproofing and is very easy to apply. However it is not for professional use when dealing with serious damage as it is not made of professional tools and material. If you have small cracks and you need something to instantly fix them, then go for it. For larger issues, it is advisable to seek the services of a professional to guarantee the safety of your concrete.
