Types of Adhesive for Concrete Walls
One of the most important things that you need to know here is that there are a few different types of glue or adhesive that you can use for concrete. This is true whether you are bonding concrete to metal, gluing concrete to plastic, or gluing concrete to concrete. Let’s take a look at the main type of adhesive that you can use for this job.
One of the best types of adhesives that you can use for concrete is a good two-part epoxy. Two-part epoxy features both a resin and a hardener. When the two are mixed together, the hardener the resin to cure into a solid material, which in this case is plastic. Two-part epoxy is extremely durable. It is waterproof and it will stick to nearly any surface, whether concrete, wood, metal, plastic or anything in between. It takes quite some time to cure, but the bond is almost unbreakable, making it one of the go-to choices for smaller concrete repairs, particularly when you need a lot of strength and holding power.
If you’re doing small concrete repairs, or you have to glue a small object to a piece of concrete and you needed to cure very quickly, then super glue is the way to go. Now super Glue doesn’t always do the best with moisture and extreme temperatures, so you may want to limit this to indoor use, but with that being said, if you need a super strong adhesive that is going to cure in just a few seconds then super glue is the best way to go. Just keep in mind that super Glue is a bit runny, so it doesn’t work well for vertical applications.
One of the best types of adhesives that you can use for concrete is construction adhesive. There are many types of construction adhesive out there, but generally speaking these are multipurpose adhesives that can stick to various types of surfaces such as tile, ceramic, wood, metal, concrete and more or less anything in between, which is exactly why they are so often used in construction. These generally come in the form of a tube that can be used with a caulking gun. A high quality construction adhesive is going to be your best bet when it comes to big time repairs and constructions.
Latex or Silicone Sealant
If you don’t really need to do actual repairs to the concrete itself, but instead you need to seal something like a bathtub to the concrete, then you won’t want to go for a latex or silicone sealant. Remember, sealing something is not the same as repairing or building in.
Concrete Glue or More Concrete
The other thing that you can try using here is a simple concrete adhesive. These are very special adhesives that are specifically formulated to adhere to porous materials such as concrete. Now, what is important to note is that exactly what type of concrete glue you get is going to depend on the second material that you’re doing the concrete to. Some are designed to glue concrete to concrete, some are designed to glue concrete to wood and so on and so forth.

First off, you need to gather all of your materials. For one, you want to wear long sleeve clothing. Next you will want rubber gloves and safety glasses. You will then also require a caulking gun. Your tube of construction adhesive, an Exacto knife or carpet knife, and a bubble level.
To ensure that the adhesive sticks as well as possible, you need to make sure that the concrete is dry and clean. So, dust it off and if necessary, wash it and then dry it. Remember, it must be as clean and dry as possible for this to work.
Now insert the tube of construction adhesive into the caulking gun and then cut off the tip from the tube. Gently squeeze out the construction adhesive onto the first piece of concrete in a zigzag manner.
With the construction adhesive applied to the first piece of concrete, take a second piece of concrete and press it down firmly onto the first one. Keep in mind that some construction adhesives may take up to seven days to fully cure, so be sure that the weather is right for the job.
