Best Concrete Block Adhesive Review & Recommendation in 2021

Cracks on concrete floors are not only unpleasant to look at, but they can also cause harm to people and affect the overall stability of a property. So, whether it is for maintenance or for building purposes, having the best concrete block adhesive is necessary.

Adhesives for concrete are designed to bond concrete to either old or new concrete. They are also used as a leveler in floor resurfacing. The exterior grade bonds the concrete to be stronger than the material to which it is bonded to. There is no need to chip, or rough up the old surface to which the new concrete needs to be bonded to. The adhesive chemically bonds to new concrete, cinder block, concrete pavement, concrete pipes, sidewalks and other materials.

 Using Concrete Block Adhesive

To make sure that the adhesive compound will bond perfectly, the surface to which it needs to be applied should be clean – free of all dust, oils, mildew, grease, wax and any other substances, however. A spray, a roller or a brush can be used to apply the adhesive to the surface. Make sure that the adhesive is thoroughly dry before applying new concrete mixes. When done with that part of the job, you need to make sure that all of the tools and other equipment that you used to do the job have been washed thoroughly, removing any drippings of the adhesive that might still be left on them.

Concrete Block Adhesive

When a concrete adhesive is needed as a floor leveler, the surface of the concrete has to be thoroughly free of grease, waxes, dirt, and other debris. Use good repair measures to repair  concrete. Shotblasting or sandblasting techniques are also used to completely clean the surface to which the adhesive needs to be applied to. A broom, a roller or a garden sprayer can be used to apply the adhesive. A second coat of the application can be done once the initial coating has dried. Drying time varies depending to the temperature and climate. If done properly, there is no need for maintenance and the resurfaced concrete will serve you well for some time.

Types of Concrete Adhesive

Projects that involves concrete will normally need a strong adhesive. Masonry bonding usually requires a stronger than the usual glue or adhesive that are used in other purposes since it must perfectly bond both the concrete and the material being attached to it.

As with the types of concrete adhesive, they vary depending on what they are made of. There are a wide variety of options when it comes to this type of adhesive in the market today. However, a few of them are designed specifically to bond well with concrete. This type of masonry adhesive is made to dry fast and be resistant to oil, water, and heat.


This type of adhesive is known for its durability and resistance to environmental or chemical damage. Since most concrete materials are exposed to outdoor elements, even harsh indoor environments, such as basements, durability is a feature that concrete adhesives have.

However, epoxy adhesives are not designed to be flexible, which makes the bond to weaker over time. And as the air temperature and moisture constantly change, this causes the bonded materials to expand and contract, thus putting additional pressure on the bond. This can cause the bond to become brittle and break eventually.

Epoxy adhesives also come in two components that need to be mixed before it can be applied to the materials that need to be bonded. To achieve optimum adhesion, the two components have to be mixed thoroughly in the appropriate ratio. Otherwise, the desired adhesive property may not be achieved.


Resin is another component in many adhesives. Most resin-based bonds dry quickly and endure much pressure without shrinking when dry. This type of concrete adhesive is usually used on heavy-duty projects, such as airport runways, highways, as well as in building parking structures.


Mortar is used for most outdoor projects and has been in the market for years. Jobs that require replacing or re-attaching bricks on a fence is one example of a job that requires this traditional masonry adhesive. This type of adhesive is usually made up of lime, sand, water, and a few other types of cement. This adhesive is usually packaged in squeeze bottles, tubs or tubes.

 Using the Best Concrete Block Adhesive

Other than the type of masonry adhesive used, proper application matters as well when using the best concrete block adhesive. The surface where the compound is to be applied should always be clean and free of other elements that will hinder the bond to do its job properly. The surface should also be dry and not too cold or hot so that the bonding agent can do its job as it should. It is also important to read the label or instruction manual that comes with the product before using it.
