Things to Consider Before Buying Concrete Glue

The market is overwhelmed with loads of different types of concrete glues, with every brand claiming to be the best. So, before you approach that cracked concrete with any kind of glue, it is wise to conduct your research first. Otherwise, you might end up regretting it after realizing that the bonding agent did not meet your expectations.

1. Usage

Every adhesive can be used as many times as possible. Nevertheless, if you will not be applying it more often, then consider something that will last long. When safe, the glue can stay in the same condition for a long time.

2. Size

Depending on where you want to apply the adhesive, an optimal size to suit your needs is necessary. So, you can pick a large-ounce pack or any other that will satisfy your requirements.

3. Price

Most of the best types of concrete glues have the same price range. In that case, your budget will be the primary factor when it comes to choosing one. The best thing to do is to analyze your adhesive needs first then narrow them down to your set budget.

Aside from the factors mentioned above, you can also consider the following points to help you in making your decision.

  • Make sure the glue is waterproof.
  • Make an informed decision of mild or strong adhesive.
  • You might also consider sag-proof concrete glue.

How to Use Concrete Glues or, Adhesive Effectively

Whether you want to fill a crack, repair a concrete section, or pour a new layer on top of an existing surface, it is vital to follow the right steps. If not, it might be difficult to bond the new concrete with the old one. Check out the following steps suggested when strong bonding is a fact:

1. Clean the Surface

First, start by cleaning the old surface. It’s mostly applicable for chips, stones, and large particles. And any other hard to remove oily dirt. You can employ a broom to remove the first layer of the detached dust particle.

You might use water and muriatic acid mix solution in a 7:1 ratio. And remember that’s a tough cleaning agent. So, you should be careful not to get it in touch. Allow the acid wash at least 10 mins to take its action against any oily tough to remove dirt.

As an alternative, you might also use a pressure washer to clean the surface thoroughly.

2. Prepare the Adhesive

Once the surface is clean, this is time to prepare the slurry. As you can see in the above list, some glues are two-part that needs mixing. So the resin and hardener need to mix in a 1:1 ratio. However, for ready-to-use adhesives, you might not have to follow those extra steps. But when required, the preparation step plays a vital role in placing a strong bond.

When applying the liquid concrete layer, prepare a bonding slurry by using white glue and water. The ratio you should maintain here is 1:1. Then add dry cement into that mixture in a 2:1 ratio. So, if you have let’s say 5 gallons of slurry, add 10 gallons of dry cement to that.

Avoid wasting your time, otherwise, the mixture will harden.

3. Prepare the Old Damaged Surface

Pick a paintbrush and apply water to dampen the old surface. Remember, you’re not going to soak it. It’s rather dampening that allows for the slurry to hold up better with the new concrete.

4. Apply the Concrete Glue

Then apply a thin layer of the slurry you’ve just created in step number 2. Please note that you need to have your new concrete ready by this time. Cause the slurry is not the thing that’s going to fill up the entire space. It’s rather your glue that’s going to help you create a strong bond.

5. Put the New Layer

Now, the last thing comes to the end. Apply the cement mixture into the place, over the concrete glue/slurry. An optimum mixture with consistent thickness should spread over easily. You might use a hand trowel to do that nicely. After that, you just keep it untouched overnight. But the complete curing might vary based on your mixture thickness.

Or, even the humidity and temperature of the area might affect that too. So, check that before you got to hurt it.

Concrete Glue vs. Mortar: What’re the Differences 

Although both concrete glue and mortar are used for bonding purposes, they are different in many ways. Do you know of any?

Well, mortar is a combination of sand and cement and is used to bind different materials such as concrete, bricks, or stones in stone masonry. On the other hand, glue is a bonding agent that is used to adhere directly. Also, it can be used to cover the cracks or splits in a concrete surface or cement slab.

That’s the basic thing, but there’s a bit more you should know:

1. Usage

Concrete glue is easy and quick to apply. So, you do not require the expertise to use it. The product is usually mixed in the lab and is, therefore, not your duty to do so. Your work is to bond it directly to the existing surface with no additional work.

As for mortar, you have to prepare it first at the construction site before you start the work. In this case, a long process is required to mix the cement, sand, and water in a specified proportion.

2. Time

Some types of concrete glue can take as low as ten minutes to set and less than 24 hours to cure. Nevertheless, the same cannot be said about mortar. For instance, it takes more than 24 hours for the thin tile mortar to dry. The others can take as long as 28 days on the same.

3. Chemical Resistance

Many types of concrete glues are resistant to most chemicals, including petroleum. Comparatively, mortar does not have high resistance to acids and other chemicals.

Acid attacks mortar by dissolving both the hydrated and un-hydrated compounds of cement. In many cases, the chemical reaction forms water-soluble compounds of calcium, which are later leached away.

4. Labor Cost

Since concrete glue is easy to use, you do not require hiring laborers. You can just decide to do it yourself, and that will, in turn, save you money.

As for mortar, you might need help when it comes to mixing the building materials involved. Unfortunately, that does not come easy. You have to go back to your pocket to have the work done.


Who likes to spend the weekend fixing that crumbling concrete? Guess no one, and it’s rather dangerous sometimes. More specifically the cement it contains is harmful if inhaled through the air.

According to EPA.GOV, “Cement plants are a significant source of sulfur dioxide, nitrogen oxide, and carbon monoxide, which are associated with health and environmental impacts.”

So, be sure to pick the best glue for concrete based on your needs. And hopefully, you’ll benefit from our list above. Cause we’ve got you back with the top-rated glues that are committed to providing durable actions on concrete material.

And you get a long-lasting result.


1. Can I glue down hardwood flooring to concrete?

Yes, you can glue down concrete slab for installing hardwood flooring either on grade or above grade. With the recommended vapor retarder, you can achieve this. Some manufacturers allow the installation of ¾ solid parquet flooring. However, you should follow the recommendations from your wood or glue manufactures.

2. How do you attach concrete together?

One of the most efficient means of doing that is by using concrete glue. You just need to clean the surface to get rid of the large particles. Then, ensure that it’s flat enough. Add the primer and, once dry, apply the adhesive or, glue. Finally, add your new concrete and wait for it to dry.

3. Can you use liquid nails on concrete? Is Liquid Nails permanent?

Well, some adhesives might be toxic since they contain hazardous solvents, preservatives, and plastics. These can either be flammable, harmful by skin contact, or inhalation. Consequently, follow the manufacturer’s instructions and use protective equipment during the application process.

6. How do you attach bricks to concrete?

Here is a simple procedure of accomplishing that:
a) Start by cleaning the surface using a brush
b) Use gloves before you start the work
c) Cut the tube of the adhesive to the bead size of the required material
d) Use a caulk gun to apply the glue into a zigzag pattern
e) Place the bricks firmly on the top and ensure they are in good contact with the adhesive
