Choosing the right coating system is important. The right choice increases productivity and means long-term cost efficiency. The wrong one might lay the groundwork for untimely and costly failures.
Foresight of which coatings are better suited for different environments leads to an efficient and effective coating job.
There are many different types of coatings that can be applied to concrete surfaces.
Coating systems that we want to compare from traditional one to advanced one are:
-Polyurethane or Urethane
-Polyasportic or F1.
Let’s go through each one and see the cons and pros and then compare them together.
Epoxy coatings are a great option if you are looking for tough and attractive flooring. They combine polymer resins and hardeners that result in a chemical bond with the concrete. Plus, there are many colors and decorative options to choose from.
Epoxy coatings are also widely used as primers to improve the adhesion of automotive and marine paints especially on metal surfaces where corrosion (rusting) resistance is important.
Epoxy resins are also used for decorative flooring applications such as Terrazzo flooring, chip flooring, and colored aggregate flooring.
Epoxy coatings make for an extremely strong, and long-lasting flooring solution. Epoxy floors thrive in commercial locations such as garages, kitchens, factories, and warehouses. Not only are epoxy floors extremely tough, but they are also highly customizable. The ability to make your floor into an incredibly strong work of art, means they are also highly attractive.
Epoxy floors are oil resistant, easy to clean, and won’t get worn down by foot traffic which is why they are ideal for residential garages.
Unlike bare concrete, they won’t get ruined by a small oil leak. Not only are epoxy floors incredibly tough, they also reflect light very well. Its proven that an epoxy floor can brighten up a room by up to 300% just due to their reflective surface.
Epoxy coatings are often used in industrial and automotive applications since they are more heat resistant than latex-based and alkyd-based paints. Epoxy paints tend to deteriorate, known as "chalking out", due to UV exposure.
Change in color, known as yellowing, is a
common phenomenon for epoxy materials and is often of concern in art and conservation applications.
Epoxy resins yellow with time, even when not exposed to UV radiation, that's why it is not recommended to be used as a clear coat.
A fully epoxy system might require up to five days, which is a long time and during this time the floor would be out of service
Polyurethane or Urethane (urethane can be used as a solvent and in a form called polyurethane)
Polyurethane is a hybrid coating similar to Polyaspartic which we are going to talk about it soon. Innovations in the technology have made these coatings a more versatile option compared to epoxy.
Polyurethanes are softer, more flexible and offer better color and gloss retention compare to Epoxy. They perform well as structural protection, are more versatile in terms of protecting assets in harsh weather conditions and offer better impact resistance.
