Things to Consider Before When Buying Concrete Adhesive

There's a need for care when selecting your best option due to the plethora of concrete adhesives available on the market. 

For a quality bonding, you'll need to consider the following factors before you part with your money.

Drying or cure time

Cure time determines the amount of time needed when installing the flooring. Normally, you'll need the right mix at every stage, and hence an adhesive that dries fast will be a perfect choice. Thus, you can walk or move things on the floor without worry.

Cure time varies depending on the quality. From our review, the best adhesive had a zero dry rate, which cures it instantly upon application.

Easy to use

The adhesive material should be easy to spread on the concrete floor or any surface. Ideally, it should be consistent neither too thin nor thick. A very thin material will wash out fast, and it's not easy to use. At the same time, a very thick adhesive doesn't spread easily.

Further, most products are self-adhesive, and during installation, you'll need to peel off the outer paper and apply it to the concrete.

Floor size

The floor dimension determines the quantity of the adhesive for your project. Consider adding at least 10% to avoid wastage. Most adhesives have labels on the package that indicates the coverage area for the application.

Durability

Durability is also the shelf life of the adhesive when left open. Most adhesives will last for up to 18 months.

However, the best concrete adhesive can be stored even for years without degradation of quality. You can keep some in the store for quick repairs. Some adhesives have a short lifespan, and hence their bonding strength decreases with time.

Easy to clean

Since concentrate adhesives are for bonding floors, and then they should be easy to clean. Generally, water-based adhesives are easy to clean when you compare to the solvent-based options. 

On the same note, a water-based adhesive may get damaged when exposed to moisture; hence they need a high level of maintenance.

Low odor

It may not be easy to find an adhesive material that's 100% odor-free. However, strong smells are hard o work with. 

For this reason, consider an adhesive with low odor, especially so if you suffer from allergies. Most of the options in our selection list have low odor.

Safe products

When buying the adhesive, check on the VOC content. VOC is an acronym for Volatile Organic Compounds which are harmful, especially for indoor application.

They can cause respiratory conditions and exaggerate Asthma. Therefore, a lower VOC content would be ideal in this case since it means it's less toxic.

Versatility

Versatility is the ability of the adhesive material for use on different applications. It not only gives your value but also makes the product multi-functional, thereby saving you some money.

For instance, you should be able to use its bond cement, granite, bath surrounds, decks, wood, metal, and more.

Also, such a product can be used for indoor applications and outdoor projects where the elements are extreme and would require heavy-duty bonding.

How to Use Concrete Adhesive

Cracks on cement or any other surface requires instant bonding to prevent damage to the entire floor or surface. Having an adhesive at home makes things easier, and luckily it's a simple DIY task. Here is how to use concrete adhesive.

  • Clean the surface by removing stones, chips, and other debris. You can sweep and wipe off with a dry cloth. If you have to clean with water, then allow the place to dry before application.
  • Get your adhesive ready by shaking the container for a few minutes. Open and pour in another container and mix with clean water in a ratio of 1:2. You can have two applications. The first one for priming while the second is for the coat.
  • Prime the cracked concrete and let the adhesive dry for a few hours.
  • After the application dries, then apply the coat by use of a paintbrush. Use a thick coat for durability.
  • When applying plaster on the concrete, use when the adhesive is tacky for better results.
