This product holds very well on existing surfaces and has some flexibility. However, it depends on the surface area as this product is aimed for use on concrete. 

Although it has good holding power, this adhesive won’t work on plastic. 

When using this adhesive on a wall, know that it may remove the entire top layer of the wall. 

If you happen to get some of the adhesives on your hands, you can easily remove it by rubbing your hands back and forth. 

Before you purchase this product, ensure that at least one item that you are gluing is porous, or the adhesive won’t work. 

While working with concrete adhesive can be quite messy, this product does not create any mess like caulk or grout

On the other hand, you may struggle with getting the adhesive out of the tube, so ensure that you keep it at room temperature at all times.

When you talk about the best concrete glues, this Gorilla glue must come at the top of the table.

It is one of the most favored glue choices due to its strong holding ability; once you apply it, it does not come off.

It’s great for fixing and repairing; it works well on wood, stone, metal, foam, glass, ceramic, and concrete.

While other glues do not expand, the Gorilla 5021801 Glue expands once applied; therefore, you end up using less product. Also, it fills in gaps in uneven joints.

Another impressive feature is that it is 100% waterproof. So, it will hold through even when liquid is applied to it or if it is exposed to outdoor elements like rain.

When applying this product, it expands 3 times into the materials creating a strong bond. Surprisingly, it also works well on foam, unlike other glues.

Gorilla 5021801 Glue has been formulated for tough repairs; however, it also works well on surfaces such as the sole of your sneakers. With just one small droplet, your torn sneakers will be like brand new again.

One of the downsides of this strong bonding glue is that it is quite messy. So, take extra caution when working with it indoors. If you happen to get some of this product on your clothes, it won’t come off.

If you don’t want hard glue stuck to your hands, I’d recommend you wear vinyl gloves.

Product Overview

It is safe to use with surfaces that are exposed to dilute acids and dilute caustics as it is chemical resistant.

Once this product has set, you can expose it to freshwater, and it will not be damaged because the E6000 High Viscosity Adhesive is waterproof.

Another impressive feature of this product is that it is not affected by temperature. So, you can expose it to extreme heat or extremely cold temperatures.

As with most adhesives, this product tends to be quite messy. When applying, you may have sticky adhesive all over your fingers, which will create little rubber balls. However, this can be easily removed.

It has quite a thick consistency, which makes it slightly awkward to work within confined spaces. Therefore, it might make your job more difficult. Also, it has a consistency similar to silicone.

When using this product, allow it at least 24 hours to set.

Car doors, wooden fencing, furniture, and ceramic tiles can all be repaired or fitted with this product. It is also suitable in hot and cold temperatures. 

Although this product has strong bonding properties, it could bubble up when applied to certain surfaces. When this happens, even it out as much as possible, using a flat utensil, to ensure that it gives off a smooth finish. 

After applying the Loctite PL Premium Polyurethane Construction Adhesive, leave it for at least 24 hours to set. Although it takes longer to set compared to other adhesives, when it dries, it forms a rock-solid finish.

It is advisable to mist your materials with water if you are using this product to join non-porous material. 

This product can cause a sticky mess, and to avoid having adhesive on your hands for several days, wear a pair of gloves. This product is not considered the duct tape of the adhesive world for nothing.

7. XTREME Bond Masonry Adhesive for Wet or Frozen Surfaces


This product is a professional adhesive that is suited for use on concrete, stone, and retaining walls. 

It contains just one component – premium polyurethane adhesive. Therefore, it contains a very high bonding strength. 

The XTREME Bond Masonry Adhesive can be used for wet or frozen surfaces. 

It creates a smooth texture when you apply it to a surface, and it sticks well. You have a time frame of about 15 minutes to work through the adhesive the way you want. 

However, this product tends to form bubbles and causes a blister-like texture. Take this into consideration when looking for a good, quality adhesive. 

This product also does not hold well to wet concrete. Therefore, this may pose a challenge if you’re considering an adhesive to be used on concrete. 

While it is said to have high bonding properties, this product does not work well on vertical surfaces. It tends to run easily. 

It also needs moisture to cure. When this product cures, it creates a hard surface. 

Another important feature to note is that the XTREME Bond Masonry may pose a health hazard. It could irritate the eyes and nose. These symptoms could worsen with prolonged exposure to this product. 

If you are intent on using this product, practice safety precautions, and handle the product with gloves at all times. 

Product Overview

If you have a few small repairing tasks, this product would be suitable. It’s highly durable and easy to use. 

It works well with concrete and can also be used to bond loose stone steps in your garden. 

What makes this adhesive very effective is how it will give off a sturdy finish that won’t result in any cracks after several months if you add it to new cement to replace over old portland cement. 

Whether you have a swimming pool that needs repairing or your patio needs some patching up, the Dap 02131 Concrete Adhesive will take care of the job. 

The drying time of a good adhesive is not necessarily short, but it could help to get the job done quicker. However, the drying time of the Dap 02131 Concrete Adhesive is not known. Therefore, I’d advise you to play it by the eye. 

This product lacks a few elements compared to other adhesives. Therefore, I’d recommend it for home use. 

If you’re working on a big construction project, instead opt for a product that is suited for large surfaces. 

This adhesive is suitable if you are looking for a no-fuss, durable, and a strong adhesive to get the job done. 

Product Overview

What is Concrete Adhesive?

Like other super strong glues that can hold anything to the surface, concrete adhesives are made to stick some other elements onto the concrete surface. They are mostly chemicals that react with the concrete to hold the foreign element on it firmly.

Well, you may have thought why not we use cement mixture to adhere to different elements to the concrete surface? Yes, you can do that but only when you are making the concrete block.

After the concrete is cured, using just the cement and sand mixture won’t keep things like iron, aluminum, or wood on the surface. That’s where concrete adhesives come in handy.

What is Concrete Bonding Agent?

Simply, bonding agents make the concrete stronger and stickier so that it holds up. These are made of different chemicals that increase the strength of the concrete so that when the concrete is poured and cured, it does not come out of the surface in pieces.

These are super helpful when you are making concrete surfaces on some heavy traffic areas like stairs, driveways, and garage. These are the areas where traffic remains heavy and generally, these are the most abused areas of your house. So, using concrete bonding agents for those surfaces can make the concrete more compact and strong so that it does not crack or break soon.

What is the best glue for concrete?

In our research, we have found the Loctite Power Grab as the most powerful and sticky adhesive for concrete that sticks to the surface within seconds. However, most of the products in our list passed the criteria on which we have chosen the best construction adhesive for concrete. So, you can get one according to your specific needs.

What will stick concrete to concrete?

Many people are unaware that concrete will stick to itself without the need for any type of adhesive. As long as the two pieces of concrete have been cured properly, they should bond very well together with just water and a little bit of pressure from tapping on it.

However, already cured concrete won’t perfectly stick to new layer. In such cases, concrete glues come in handy.

What is the strongest construction adhesive?

The strongest construction adhesive is epoxy. Epoxy adhesives are very strong and will stick to most surfaces without the need for any additional bonding agent, but it needs a long time to cure before being able to be used.

How do you attach concrete without drilling?

Screws are one of the easiest ways to attach concrete without drilling. If you have a smaller piece that needs attaching, using epoxy glue will work as well. For long pieces, use steel rods and cement mortar with screws for support in between the two segments.

Can you put a thin layer of concrete over concrete?

You can put a thin layer of concrete over old concrete but it is not recommended. The reason for this is because the new mixture will have different properties than what you are covering up and may cause your floor to sink or crack. If you do decide that this is something that you would like to go through with, make sure to use backer boards to protect your old concrete.

What are the best ways to avoid water leaks?

When you are installing a new concrete floor, make sure that if there is any chance of future flooding in the basement or garage that it is sealed off completely with waterproofing sealant and an outside wall. This will help prevent moisture from seeping in and causing your new floor to crack.

How do you attach concrete to old concrete?

The best option is to use a self-leveling concrete adhesive. This will allow you to avoid the old floor and create a new foundation on top of it, which can then be poured with your desired material over that. Make sure to wear gloves while working because this type of adhesive has an extremely strong stench!

Can you glue metal to concrete?

No, but there are a few different options when it comes to attaching metal to concrete. You can use screws and hardware anchors to secure the metal, which will help you avoid any future problems with loosening or corrosion. If using this method though, make sure that they’re coated in PVC cement for added protection!

How do you attach concrete blocks to concrete slab?

The best method for attaching concrete blocks to a slab is with the use of metal anchors. If using this method though, make sure that they’re coated in PVC cement for added protection!

Can you install composite decking directly on concrete?

Yes, you can install composite decking on concrete. The installation process will require a few tools and materials from your local hardware store, but it’s not too difficult to do!

How do you secure a 2×4 to concrete?

To secure a two-by-four to concrete, you’ll need some type of anchor. There are many types available on the market; one commonly used is called an expansion bolt. These work really well and should be screwed into the wood first before being inserted into the hole in the concrete surface!

Some may directly put the wood into the concrete but the joint may start deteriorating after a few years. So, it’s better to go with anchor.

How to Glue Concrete?

Gluing concrete is not something to be afraid of. This is similar to other adhesion works. However, you need to follow some key steps to have a solid bond between the concrete and the material you are trying to glue to the concrete.

1. Clean the Concrete Surface

The first step is to clean the surface thoroughly. There should not remain any dust at all when you apply the concrete glue. So, a pressure washer is what we recommend for the task. If you don’t have one, you can use a brush and water hose to get rid of the dust.

2. Read and Follow the Instructions

Different construction glues come with different formulas and they work differently. So, you need to check the product label or the manual to learn the process. Some glues do not require any process other than pouring on the surface and holding the materials together for a few moments.

While some products come in two or three different bottles that you need to mix before application.

3. Make the Surface Abrasive

For better bonding between the materials, it is recommended to have the surface scratched up. Scratching up the surface will make the bond stronger and long-lasting.

You can use a simple wire brush or some screws to scratch up the surface a little bit. And, don’t forget to get rid of the concrete debris that you scraped from the surface.

4. Apply The Concrete Glue

Apply the glue on the surface according to the manufacturer’s instruction. When applying the glue, make sure you have the material close to your hand so that the glue does not cure before you hold the material against the concrete surface.

5. Let it Cure

After application, let the glue to cure for a day. How much time it needs to cure depends on various factors like humidity, temperature, and the ingredients used in making the glue. So, it should be written on the product package.
