Many people think concrete can’t be fixed or joined with glue or adhesive. But, in reality, this is a complete myth. You can also join concrete with adhesive for your convenience.
However, when it comes to joining concrete with adhesives, you might wonder which adhesive can actually join concrete with different surfaces.
And this might make you wonder what adhesive sticks to concrete.
To help you out in such a situation, I have discussed the types of adhesives that work on concrete. Go through the list below to find out more.

What Adhesive Sticks to Concrete?
Here is a list of the adhesives that stick to concrete. Explore them to find the one you need.
1. Epoxy Adhesive
One of the most common yet effective adhesives that you can use on concrete is epoxy adhesive.
This adhesive is incredibly versatile, strong, and durable and can be used to stick concrete to different types of surfaces.
Made with a combination of resin or epoxy polymer and a hardener, epoxy is a thermosetting adhesive that can easily withstand high heat, extreme stress, and weather conditions. Its bond on concrete won’t come off anytime soon.
That’s not all. Even though it is a two-part adhesive system, epoxy resin adhesive is super easy and fuss-free to use. You won’t have to go through any hassle to use it on your concrete surfaces.
Advantages of Epoxy Adhesive
- Creates a super strong bond.
- The bond is durable.
- Can withstand heat and weather.
- Works on even porous material.
- Suitable for all types of concrete.
Limitations of Epoxy Adhesive
- It takes longer hours to cure.

2. Polyurethane Adhesive (PA)
Another type of adhesive that works incredibly well for sticking concrete is the Polyurethane adhesive (PA). It is a polymer-based, thermoplastic adhesive that is heat and chemical-resistant, creating a strong, durable bond between surfaces.
Also, one notable property of PA adhesives is that they are super flexible. It means that you can alter the bond and its pattern until the glue is fully cured.
That’s not all. As this glue dries to a clear color, there won’t be any trace of the bond once it dries down.
However, PA adhesives aren’t suitable or compatible with plastics. Therefore, if you want to attach plastic to concrete, this glue won’t work.
Advantages of Polyurethane Adhesive
- Heat and chemical-resistant.
- Versatile; works on different surfaces.
- It can withstand more wear and tear.
- Waterproof and long-lasting.
Limitations of Polyurethane Adhesive
- It might be a bit toxic; you must handle it cautiously.

3. Polymer Adhesive
Made from different polymer-based bonding substances, polymer adhesives can efficiently attach different types of concrete, including ceramic tiles and other surfaces.
As polymer adhesives are synthetic and man-made, they can have specific properties to fulfill your specific demands.
Be it flexibility, thermal resistance, chemical resistance, or electrical conductivity, these adhesives can be formulated to meet your unique adhesion needs.
Advantages of Polymer Adhesive
- It is super versatile.
- Heat, chemical, and weather resistant.
- Lasts for a long amount of time.
- Easy, fuss-free to use.
Limitations of Polymer Adhesive
- It might be a bit difficult to remove.

4. Construction Adhesive
As the name suggests, a construction adhesive is a special type of glue that is specifically used to attach concrete construction surfaces together.
Be it a drywall, tile, molding, fixtures, ceiling, or floors, this glue will create a strong, durable bond that won’t come off anytime soon.
Another advantage of the construction adhesive is that it is 100% waterproof. It means that the bond won’t come off easily.
Advantages of Construction Adhesive
- Creates a super strong bond.
- Waterproof, heat-resistant, and durable.
- Works on ceramic tiles as well.
Limitations of Construction Adhesive
- It requires a long time to cure properly.
5. Concrete Glue
As the name implies, concrete glue is a ready-to-use polyvinyl acetate (PVA) emulsion that creates a bond between concrete surfaces.
As it combines polyvinyl acetate and a strong bonding agent, this glue can adhere to concrete successfully. It can create a strong bond that lasts for years to come.
Be it new concrete, underlayments, masonry, stucco, terrazzo, or Portland cement/sand mixtures, concrete glue will never fail you.
Advantages of Concrete Glue
- Incredible flexible.
- Suitable for different types of surfaces.
- Creates a strong, long-lasting bond.
Limitations of Concrete Glue
- Not too environment-friendly.
Editor’s Opinion
Even though not all adhesives work similarly to adhere to concrete, the ones I have discussed above are some of the best.
These glues are versatile and work amazingly well to attach concrete effectively. You don’t have to believe my words.
Just try any of them and see the results yourself. I can guarantee you won’t be disappointed.
