Concrete is used to create a lot of structures all over the world. However, they are not resistant to wear and tear over time. Concrete expands when it rains or freezes, creating cracks in hard surfaces.
These cracks allow water to seep through and weaken it from below, reducing durability. To repair such a concrete structure would cost a fortune due to the cost of building materials. However, an economical and cost-effective way to make repairs on concrete is using a concrete adhesive.
In the past few years, the demand for a stronger concrete adhesive has increased in correlation with the construction boom. Its importance cannot be overstated. Today, there are tons of concrete adhesive in the market.
However, there is a handful that stands out from the crowd. That’s what we are here to discuss. So, if you are searching for a concrete adhesive, read this well-detailed review of the 10 best concrete adhesives in the market. After which, we will educate you on some factors to consider before buying one.

Best Concrete Adhesive Buying Guide
When you’re shopping for a concrete adhesive, it can be overwhelming not to know what to consider before making a choice. You want an adhesive that will work well with your project and doesn’t cost too much, but how do you figure out which one is the best? Many factors go into this decision. To simplify your shopping process, we have compiled and explained a list of factors to consider before buying a concrete adhesive.
The material you intend to bond to the concrete:
The type of material you are bonding to the concrete will determine which adhesive is best for your project. If you want something that’s strong and durable but doesn’t need a lot of flexibility, you’ll want to use a high-strength adhesive. If you’re looking for something flexible but doesn’t have much strength, you should go with an epoxy or polyurethane sealant.
The set time refers to the duration of time and how long a concrete adhesive can be repositioned before it hardens. Good concrete adhesives should take 10 to 30 minutes to set. Long set time is beneficial for large repairs because it gives you enough time to properly apply the adhesive before it permanently bonds with any surface. You will also use less adhesive if the product has a longer setting time. However, if your project is small and time-bound, it is ideal to use a concrete adhesive with a fast set time.
The cure time refers to the duration of time a concrete adhesive takes to reach its maximum hardness, 100% dry. Ideally, a good concrete adhesive full curing time should take from 2 hours to 72 hours. However, there are still some good ones that take weeks to cure. Longer cure time doesn’t equate to more bonding time and vice versa. It all depends on your preference and the demands of your project.
Adhesives are in the liquid state, and as we all know, liquid viscosity depends strongly on temperature. The application temperature refers to the atmospheric temperature that needs to be met for the adhesive to function well. With most adhesive, there’s a range of application temperature that varies from cold to hot season, meaning they work well in both seasons.
The Adhesive’s Strength:
The strength is the adhesive’s ability to resist deformation, especially elongation. Strength is measured in PSI, and higher values indicate greater strength of the concrete adhesives.
The shelf life is the length of time that an adhesive will retain sufficient strength for use when stored.
Water resistance refers to how well concrete adhesives resist moisture and liquid penetration.
There are two types of application methods- A trowel and a caulking gun, depending on how the adhesive is packed.
Trowel: A trowel can be used to apply the adhesive by wiping it on the surface and then pressing them together with pressure from your hand; this will create a seal. Trowels work best when you have a large area to cover.
Caulking gun: This tool is more suited for applying adhesive that comes in a tube form. The adhesive is pumped into the gun then applied to the surface by pressing the trigger. Using a caulking gun is the best way to apply adhesive where precision is of utmost importance. However, it doesn’t work well for large areas because it doesn’t dispense large quantities at once.
Most adhesives are made from chemicals, and these chemicals do produce an odor. However, there are some adhesives on the market that the manufacturers have been able to formulate to produce little to no odors at all. It is recommended you choose a low-odor option if this will be an issue for your application as it will reduce any discomfort or irritation.
Since we are dealing with concrete here, the ideal adhesive should have a gray color when fully cured. However, depending on your application, you should go for an adhesive that matches the color of the surrounding you intend to use it on. Or, that can be painted.
Easy To Clean:
It is crucial to ensure that if spills occur or mistakes happen, getting the adhesive off won’t be too difficult. You don’t want to have tons of trouble cleaning up your mess and ruining hours’ worth of work with those stubborn glue spots. Most tough adhesive comes off when they come in contact with acetone.
Adhesives are chemicals, so user safety with these chemicals is a top priority. Ensure that the adhesive you read all the safety data of an adhesive to ascertain if it is harmful. However, we advise you to wear safety gadgets when working with an adhesive.
Most adhesives are not expensive, but quality varies. A good rule of thumb is to stay away from the cheaper ones and invest in a more costly one if you have the money available.
When you’re looking for an easy solution to repair cracks and split on surfaces, there’s nothing better than a concrete adhesive.
Repairing cracks and splits on surfaces is now easier than ever thanks to their invention. Moreso, concrete adhesive can be used in a variety of ways and on different surfaces, both porous and non-porous.
We have thoroughly reviewed each concrete adhesive on our list, covering their color, tensile strength, set time, cure time, etc. You can easily select and purchase your desired adhesive to use for any job. The factors we discussed should help you make a more informed decision on which adhesive is perfect for your needs. Finally, we hope this information has helped guide you towards the perfect concrete adhesive for your project.
