Most flooring is made of concrete (garages, warehouses, basements, etc.). Concrete flooring offers the following characteristics:
Benefits of Concrete Flooring:
- Heat Resistant

Drawbacks of Concrete Flooring:
- Attacked by Acids & Chemicals
- Difficult to clean
- Easily eroded and damaged
Due to the apparent disadvantages of concrete flooring, nowadays many business owners use epoxy for commercial and industrial floors to protect the floors from abrasive or chemical damages, also save money in the long term, and enhance the value of their business.
All epoxy technology used in the coating industry today comprises two essential components, a resin (epoxy) and a hardener (amine blends), reacting together to form a tough strong plastic material. Sometimes there is third component filler (aggregate). These types of reactions are known as “exothermic reactions”. The initial gelletion reaction takes place within minutes to a few hours, and then continues reacting slowly afterwards for 7 days, gradually getting harder and tougher. Epoxy coatings are formulated based upon the performance requirements for the end product. When properly catalyzed and applied, epoxies produce a hard, chemical and solvent resistant finish.
Epoxy resins were the first technology to become established in the flooring market and continue to be the best. Epoxy offers the flooring industry the following advantages:
- Excellent adhesion to almost all construction materials
- Easy to install (long working time)
- Very low shrinkage during curing
- Adheres to damp surfaces
- Excellent chemical resistance
- High mechanical strength and abrasion resistance
- Excellent handling properties
- Not affected by humidity during applications
- Low maintenance cost
- Relatively safe and environmentally friendly
Concrete Flooring Solutions
High build coatings are a high solids (over 90%) or a 100% solids material applied by a squeegee in two-coat applications (primer + top coat) to a dry film thickness of15-20 mils. This type of flooring offers rapid installation and good protection against chemical, wear and abrasion. A sand or alumina aggregate may lightly be broadcasted onto the floor for slip resistance and back roll to encapsulate the aggregate onto the coating. Alternatively Jordan Group Construction offers non-Slip additives that can be mixed in and applied by squeegee and roller generating much more uniform attractive finishes. For heavy-duty applications, a fully seeded system may be used in conjunction with an epoxy tie coat sealer.
Self Leveling Floors
These are usually three-part epoxy systems, consisting of an epoxy resin, a hardener and a blend of fine sand aggregate (50 to 200 mesh), filler content: 55-75%. They are applied using a notch squeegee and spike roller (see Figure 1). Due to the excellent inherited self-leveling property, the material flows to form a monolithic smooth, hard, and glossy surface of 60 to 120 mils thick in a single coat application. This installation is gaining significant acceptance in the industry in Europe and Far East, but as much in North America. It is particularly suitable for warehouses, showrooms, laboratories and manufacturing processing facilities.
Trowel Floors (Heavy Duty)
Troweled floorings are generally used in heavy industrial application or selective commercial applications. Fillers such as sands are incorporated in the matrix to improve wear and impact resistance; filler content: 80-90%. The system is typically applied by using a hand trowel or power trowel machine to a thickness of up to 1/4 inches, depending on the product type and the site requirements. Trowel applied installations may also include decorative colored quartz floorings.
