We tried many adhesives from multiple brands and here is our list of the best concrete adhesives.
There are special glues called concrete adhesive to attach concrete to concrete or other materials. It is not an ordinary glue; given the fact that concrete is porous and difficult to glue, the adhesive is strong.
You have to apply the concrete sealer properly to let it stay for long.

- Made up of 100% polyurethane
- Suitable for indoor and outdoor projects
- Performs better than original PL premium formulation
- Suitable to bond all sorts of wood, concrete stone, etc.

This concrete adhesive worked well for all my indoor projects; it gave me a lot of flexibility to stick the concrete stone exactly how I wanted to.
Similarly, my vintage pot broke entirely from one side, and without any hope, I tried this adhesive, and it glued back the pieces without any visible cracks! It felt like never broken before.
It dries up in nearly 10 minutes which is good since you can use the product immediately without worrying about cracking up again.
One issue I faced was that the glue dried up in the tube because of air before I even got the chance to use it. It was difficult to squeeze it out, but I was able to manage eventually.
2. Gorilla Heavy Duty Construction Adhesive
The gorilla store makes all kinds of adhesives, but their concrete adhesive particularly stands out. Let’s check out its features:
- The product is imported
- Volume is 9 ounces
- Best suited for building and house improvement projects
- Holds in 30 seconds
- Suitable for all kinds of weather
- Works for indoor and outdoor projects
- Contains no solvents or water
From my personal experience: I realized, you need a caulking gun to use this adhesive, so keep that in mind. It dries up like a silicone sealer and efficiently seal gaps between bricks that it does not even show.
It hardly takes a minute to apply this concrete adhesive, and at a scorching temperature, I was able to coat the panel, and it dried up in a couple of minutes. The seal can be cut off with a knife and then proceed to use.
If you want to glue a crate to a wall, this one should be your go-to adhesive. Put the glue on one piece first and let it sit for around five minutes before you move on to another surface.
I faced one Problem: The adhesive started leaking from the base of the tube that led to a colossal mess and wastage. It would have been better if the nozzle wasn’t removable.
3. Liquid Nails – LN-905 Landscape Block Adhesive
This glue’s characteristics outshines among other brands of concrete adhesive; let’s have a look at them:
- Suitable to build walls and stonework
- Prevents wall from shifting
- Works in all weathers
- 10-ounce cartridge with a coverage of 13 lineal feet
- Not recommended for immersion applications
- Ideal for brick, stone, and concrete
The quantity was remarkable for the price; a single tube glued together 5 sets of two cinder blocks for a bench I was making. Other glues provided lesser ounces and smaller tubes for the same price.
Moreover, it is worthwhile to note that the adhesive delivers on its promise; even during heavy rains, the glue didn’t budge and remained steadfast.
This concrete adhesive is durable and works long-term: even after a year and a half, the landscaping blocks are still in place and holding strong. The long life of it makes it affordable.
It is crucial to note that the adhesive sometimes fails on cement blocks of the landing edge and glue remains wet. You can get it replaced in that case.

We tried this adhesive on a severely cracked garage—it worked seamlessly for me, and took 3 tubes of this concrete adhesive for etching the floor.
The floor looked perfect with a smooth surface. I would like to advise, though, not to stress too much about making the surface extremely smooth or you’ll make it worse.
The good thing is that no bits and pieces fall or are left behind of the concrete block when you are in the process of gluing it or attaching it with the adhesive; it is completely mess-free. Even if the block does come off, it comes off in one piece.
Moreover, the customer service post-delivery is smooth and hassle-free. The operator is knowledgeable about the product and will try to solve your issue as soon as possible. My experience with their support is good.
However, this concrete adhesive is difficult to squeeze out of the tube, even if one goes by its instructions.

The instructions are easy to follow, and anyone can get the job done, given they don’t have prior experience with this stuff. This adhesive is convenient to apply and cures quickly.
One issue that often comes up is the consistency of the glue; sometimes it becomes hard and thus, it is difficult to get it out of the tube.

To save you some time here is a useful tip; cut through the nozzle and then pierce the seal below it for the glue to start coming out. It is a convenient method; tried and tested!
The concrete adhesive is strong; there is very little chance that the concrete would fall off or break after being glued to a surface.
The downside is that the glue may be a bit hard and it might be a bit troublesome to squeeze it out.

The process of applying is convenient than I anticipated it to be, even if you have to apply multiple tubes of it. It is quick and mess-free.
It should be noted, however, that it takes a while for this concrete adhesive to dry up. So, if you are in a hurry, you might want to reconsider.

Also, the concrete adhesive can withstand heavy weight easily! I used it on a concrete step that had broken off and it bonded it right back and it hasn’t come off ever since.
What stands out in this adhesive is that it can bond almost anything; I used it to patch tiles, glass, and whatnot and it stuck well with all!
For filling up cracks and gaps, this should be your go-to product. The durability makes it worthwhile as you won’t have to redo anything.
However, sometimes the tubes are already hardened when they’re delivered. You can take this up with customer service easily, though.

For my sandstone countertop, the color was a match, and I used this concrete adhesive to fill a chip in it, and it gracefully fixed the counter with no issues whatsoever. One tip: it does not work on wax paper.
For a broken gas tank, apply the adhesive enough to fill the crease, and then using water, you can smooth it out. Let it dry for a maximum of 24 hours, and it is repaired!
Considering the cost of replacing a concrete step or a tank, it is way cheaper to fix it up using adhesives. Thus, this one should remain on your buy-list.
However, the product delivery can be improved. The packaging was a bit messy, and some tubes had leakages.
10. Red Devil 063712 Acrylic Asphalt Crack Filler Sealant
- Colored and textured like asphalt
- Makes a watertight seal
- Flexible with all weathers
- Suitable for damp surfaces
- Can be cleaned up with soap and water
The consistency of the adhesive is just right; it is thin enough to ooze out of the tube easily and thick enough to create a bead over the crack. You can smooth it up later with a knife.
If you want to fill up driveway cracks, cut the nozzle as small as possible to fit it into small cracks and fill it just above surface level and keep the caulking gun going.
Wipe off the excess with a slightly damp cloth. The unused tubes remain as is, to be used in the future. They do not become hard as a rock, and that’s a major convenience.
Keep in mind that it does take a while to dry up, especially in areas with higher temperatures.
What is the best concrete adhesive for your projects?
For projects like floor tiling or repairing the driveway, you’ll need durable construction adhesive that can withstand heavy traffic and can survive in brutal temperatures.
For gluing a concrete stone or brick veneer inside your home, opt for glue that works vertically so you can work it up and down the wall and provide more coverage as well.
How to store and apply concrete adhesive?
Concrete adhesive can be stored in two forms:
Tubs require mixing and have to be applied to both surfaces. If your project is small and needs less amount of glue, the caulking technique is the best. Prep space first and add the cartridge to the caulking gun and run the applicator.
Given that you have to bond two different surfaces together, like wood to glass or concrete to metal, it would be best to go for an adhesive mix that provides a bond through pre-filled glue syringes. You can find specific adhesives for metals and other material.
I grew up on a small farm in New Jersey. We had a big family because my parents, my uncles and aunties all were living together on this farm so, you can imagine, it was always over crowded with people. But living in farm was really great because we had to do everything on our own and I learned so many things from my parents and uncles and aunties and that is where I found my passion for fixing things, whether it is renovating or designing, I was always there.
