Concrete floor coatings are available in a variety of styles and colors. These coatings protect concrete floors underneath from wear and prevent corrosion of steel reinforcement. (For more information on the corrosion resistance in reinforced concrete structures, please see Corrosion Resistance. Floor coatings are also available in many cases.

This article will discuss some of the most popular concrete floor protective coatings. It will also give you an overview of their benefits, drawbacks, and typical applications.

Epoxy Floor Coatings

Two distinct components make up epoxy floor coatings: an epoxy resin, and a polyamine-hardener. The two components must be mixed before they can be applied. The resin and hardener react in a chemical reaction, which causes cross-linking as the resin cures. The chemical reaction results in a hardened, rigid coating material made of plastic that bonds well with most base layers.


Epoxy floor coatings have a reputation for being durable, hardy and impact resistant. Epoxy coatings are ideal for heavy-duty applications like warehouses, logistic centers, and industrial facilities with heavy forklift traffic. Epoxy is known for its resistance against chemicals such as bleach, oils and greases, cleaners, and other cleaning products. They are a popular choice for garages in the automotive sector because of their chemical resistance.

Epoxy floor coatings have a complex application process. It can be time-consuming to prepare the surface. Epoxy flooring should not be applied to damaged, contaminated or unprepared surfaces. The floor must not contain any oils, greases, or solvents to ensure its durability. Concrete surfaces that have been damaged must be repaired. The concrete may also be ground to expose its pores and profile the surface. Learn about this process in 6 Ways To Measure Surface Profiles For Concrete Surface Preparation. This material also takes seven days to cure, so epoxy floors take longer to turn over than other coatings.

Polyurethane Floor Coatings

Polyurethanes can be polymers linked to a group of chemical compounds known as carbamates. Polyurethane by nature is a thermosetting plastic, meaning it doesn’t melt when heated. Polyurethane coatings can look visually similar to epoxy floors to the untrained eye. They have distinct properties that make them suitable for certain applications.

Polyurethane floor coatings have a lower stiffness and greater flexibility than epoxy coatings. Polyurethane floor coatings are better suited to areas with moderate to heavy pedestrian traffic. Polyurethane floors with higher elasticity are more resistant to abrasion because they absorb impact loads better and are less likely to scratch. Polyurethane’s flexibility and elasticity make them suitable for low- freezing environments.

Polyurethane floor coatings are ideal for many applications.

Another advantage of polyurethane flooring coatings is their quick curing. This material can be applied to floors within a day. Epoxy coatings, on the other hand, take at least seven days for them to cure before being ready to use.

Polyurethane has many benefits, but they also have some drawbacks. First, polyurethane floors can be very sensitive to moisture. Bubbles can form on the floor when moisture is present. This can cause unsightly blemishes. High humidity areas are not recommended for polyurethane floor coatings. They are also difficult to work with due to their limited pot life and high moisture sensitivity. Polyurethane coatings require skilled and trained personnel to apply and handle correctly.

Polyaspartic Floor Coatings

Polyaspartic can be subsets of polyurea. You can find more information on polyurea coatings in the article Industry Adoption of PolyureaCoating Systems. Polyaspartic, like polyurea floor coatings is a two-part process. The resin must be combined with a catalyst to speed curing and hardening. Although polyaspartic floor coatings were initially flawed, modern coating technology has made them a more versatile option to epoxy and polyurethane.

Polyaspartic can be used both as a flooring system and as a topcoat. This is one of its primary advantages. Polyaspartic floor coatings can accomplish in one coat what traditional epoxy or polyurethane would require two coats. Polyaspartics are able to significantly reduce the time required for application, labor, and material costs.

Polyaspartic floor coatings have another advantage: they can be customized. Polyaspartic esters can be controlled for drying times and pot life. This allows assets to be returned to service quicker and reduces the lag time. Some coatings dry in hours and can be returned to service within the next day.

They can be used in many applications because they have the same properties as their polyurethane counterparts. These areas include areas that receive medium to high foot traffic such as malls, shopping centers and airports.

Polyaspartic floor coatings are similar to epoxies in that they require careful preparation. Poorly prepared surfaces can lead to various types of coating failure. Polyaspartic coatings containing 100% solids have low volatile organic compounds (VOC) emission rate, but most polyaspartics use solvents. These solvent-based coatings are dangerous to inhale. Therefore, it is important to have skilled labor and the appropriate equipment for respiratory protection during application.

Acrylic floor coatings

Acrylic floor coatings typically contain more than one monomer such as ethylacrylate, methylmethacrylate, or butylacrylate. These components are usually processed in a solvent, which is often water. These floor coatings are a compromise between cost and performance.

Acrylic floor coatings may not be as long-lasting as epoxy and polyurethane. Acrylic floor coatings may require more frequent re-coats or buffing than other coatings. Acrylic floor coatings are relatively affordable initially, but long-term maintenance costs can be more expensive than other coatings.

Acrylic floor coatings do not suit decorative concrete surfaces, areas that are less frequented by foot traffic and areas where chemical spills and abrasions are unlikely. Certain acrylic formulations can have superior performance characteristics such as increased UV protection, slip resistance, and water resistance.

Acrylic floor coatings are not as durable as other types, but they can be dried in as little as one hour. This allows for a reduction in labor costs and faster turnaround times. In the unlikely event that the coating is damaged, it can easily be buffed.


Concrete floor coatings in nz have unique benefits and properties that can be used in many applications. Concrete floor coatings can be used for a variety of purposes.
