Surface Preparation for Concrete Coating Applications

 

Surface Preparation is Key to a Successful Coating Application

Surface preparation is arguably one of the most important tasks of the concrete coatings process. For this reason, we want to take a moment to walk you through why it is so important to prepare a surface for resinous coating adhesion and how we make sure it is done properly.

 

Why is Surface Preparation So Important?

Surface preparation is important because if it is not done right, the coating system could fail. For instance, if the moisture was not tested and there is too much moisture in the concrete prior to coating installation, or the concrete slab was not repaired or leveled, the coating may delaminate quickly. The reason our coatings last longer than other competitor’s is because of the pride and time we take in preparing the concrete surface for adhesion. In addition to this, we also use high-performance materials that may cost more upfront, but will be a longtime investment.

How Do We Prepare the Surface for Proper Adhesion?

Our team will ensure that your concrete is prepared and repaired, so that your concrete coating will adhere. Look at the following ways we prepare the concrete prior to resinous flooring application.

  1. Repair the concrete.
    • Fill cracks with flexible joint filler.
      • Cracks generally must be bigger than a credit card width to warrant chasing them and filling them for the integrity of the concrete slab.
    • Level the concrete where needed.
      • Concrete must be as flush as possible for coatings to adhere properly.
    • Apply a cementitious layer and patch spalling concrete areas where needed.
  2. Grind, shot blast, or sandblast the concrete surface.
  3. Acid etch or mechanically prep the concrete.
    • Concrete needs to be a rough, sandpaper finish for the coating to adhere. This can be done either with acid etching or mechanical preparation.
  4. Dry mop the concrete or clean the area surface from dirt and debris.

And to Sum It Up…

Once the concrete is prepared thoroughly and to industry standards, it is time to apply the resinous coating system! This is the exciting part because this is the part you get to see the result! One thing to consider before moving on, however, is in this process it is important to do proper moisture vapor testing to make sure the concrete’s moisture level is within industry standards to apply a coating. Otherwise, moisture will affect the coating’s adhesion. Also, we’ll give you our honest opinion if you would be better off replacing your concrete if we do not think we can repair it well enough for a coating to adhere properly.

Epoxy Coating for a Fort Collins City Building

Epoxy Coating Project Complete

We completed an epoxy coating project in the Fort Collins Power and Light office building this past month. The client chose to install the quarter inch Copper Mountain flake epoxy system, so that it would be easy to clean, durable to high traffic, and look good. The job was a big success! We transformed 15,000 square feet of rough and unlevel concrete that was previously carpeted into a beautiful, seamless, easy-to-clean floor. The client had decided on this application after having a previous section done and having seen how well it performed with workers walking through the area with muddy boots.

 

The Process:

Prepwork is arguably the most important part of our trade, and with this floor, we needed to focus on repairing the surface so that it would be nice and flat for the coating to adhere. We moved old pieces of concrete that had broken due to the concrete settling and cracking over time, as well as we filled a lot of cracks and grinded the surface smooth. The floor also required moisture remediation after testing. The moisture remediation consisted of a special primer needing to be installed on the floor and extensive patching to ensure adhesion of the epoxy chip coating. The prepwork laid the foundation for a nice industrial floor coating.

 

Why Epoxy?

The client chose this system to be installed in the high traffic areas, like hallways and large rooms, where people would gather and walk through often. They decided to carpet the offices, which can often be a good decision for a cozier feel for people’s workspaces. Concrete floors can be a nice addition to a mixture of flooring types, depending on what they will be used for. In this case, the city will be happy with the mixture of epoxy coating and carpet for their usage because the epoxy is industrial-strength and looks good, whereas the carpet does not get as much traffic and provides a nice environment in the office setting.

 

Some things to consider when choosing an epoxy floor application…

Whenever our clients choose an epoxy for paint, we want to be clear that there could be odors associated with the resins we use, and really, you’re going to get this with any contractor. However, there are ways to reduce the odor, which is what we did in this case. Products were selected to reduce odors because part of the building was occupied. Another thing we want our clients to be aware of is the drying times, which can be longer or shorter depending on the temperature of the concrete and surrounding environment. Depending on the material used, our clients may be able to walk on it the next day, or it could take an additional day if it did not dry quick enough. Also, be careful and consult with us before you drive any machinery on the surface when we’re finished.
