HOW TO CHOOSE A CONCRETE COATING
THINGS TO CONSIDER
Concrete coating technology is rapidly evolving balancing beautiful aesthetics and high-performance functionality. There are so many options to choose from and so much variance in price. To get the most for your money, it helps to understand the four primary classifications of concrete coatings. Concrete coatings classifications include:
Thickness – Protective concrete coatings come in a wide variety of different thicknesses. Some as thin as a film of 1 to 10 mils. Others as thick as 10 and 30 mils, slurries of 40 to 125 mils, and toppings/overlays that start at 125 mils and go up to 1/2 inch or thicker.
Polymer Type – Concrete coatings are also classified by the type of polymer, including polyurethane, vinyl ester, epoxy, polyester, methacrylic, methyl, and others. Among thousands of unique formulations, polyurethanes and epoxies are the still the most popular due to price and performance capabilities. For thin-film to high-build coatings, urethanes are generally used because of their longevity and ability to defy abrasion. They also tend to have greater acceptance of chemical and stain enhancements.
Aesthetics –Nowadays, a good flooring contractor (like us) can install concrete coatings that resemble marble floors, wood, rusted sheet metal, etc. We can customize your floor to match the aesthetics you desire.
Flooring Finish – The finish is an important category. The concrete floor coating can be smooth or textured. Smoother textures are easier to clean and tend to be more reflective, while more textured surfaces can offer slip-resistant qualities.
The Most Important Things to Consider when Choosing a Concrete Coating
Is your concrete coating going to be subjected to heavy forklift traffic or constant impacts from tools or other equipment? How about hot grease or freezing temperatures? The type and severity of abuse are important factors to consider when choosing a floor coating.
Chemical Exposure – Chemical spills, exposure to acids, and the products used to clean up all put significant stress on a concrete floor or wall coating. When choosing the best type of coating, first identify all the types of chemical exposure your floor will face.
Abrasion – The type of wear or traffic on the floor’s surface is extremely important to consider. Not only foot traffic but also heavy equipment too.
Impact – Along with a thicker or heavier floor system, the right floor coatings can handle impact from heavy loads. In facilities where tools get dropped, pallets get stacked, etc., these impacts can have major detrimental repercussions if a concrete floor is not coated properly.
Thermal Shock – Without the appropriate flooring system and coating, any type of thermal shock causes a loss of bond. Whether is due to the extreme cold or heat, your coating may delaminate if it’s not the right one for your facility’s needs.
Electrostatic Dissipation – If you have electronic equipment sensitive to static electricity, you may need a concrete coating that has electrostatic dissipative qualities. These coatings are often found data centers, electronic manufacturing, air force bases, etc.
