Epoxy Coat or Polish Concrete?

Updated: Apr 28

One of the most common questions we receive from customers is regarding the differences between grind and seal flooring and polished concrete. When deciding on a new floor system, most clients know what they are looking for, but don’t quite know the exactly correct choice of flooring. Grind and seal floors are oftentimes confused with polished concrete, as both give the appearance of a glossy finish over rustic concrete.

However, there are some major differences between the two, and it is important to know the pluses and minuses of each before having a resinous flooring expert install a flooring system in their facility.

What Is Polished Concrete?

Customers usually ask for polished concrete floors when stating that they would like a shiny concrete floor. However, even though the name clearly states that this is the process that would produce a polished floor, the fact is that oftentimes that is not the case.

Since polished concrete flooring requires a very strong concrete base, many times the concrete slab inside your commercial facility is not appropriate for polishing. This leaves customers unsatisfied with the finished product. When distinguishing between the two, it is important to note that polished concrete achieves its sheen in a completely different way than grind and seal does and that it is more labor-intensive as well, and typically is3x the cost of an epoxy flooring system.

The process involves polishing the surface of a concrete slab with a machine that is fitted with industrial diamonds. The diamonds polish the floor until it reaches its desired level of shine, and a Gard solution is applied as a seal coat.

What Is Grind And Seal Flooring?

Typically, the shiny concrete floors that you see in commercial facilities are grind and seal concrete flooring, not polished concrete. Grind and seal floors offer more sheen than polished concrete, and it works on most concrete surfaces as well.

The process of grinding and sealing involves grinding the concrete substrate with concrete grinders, filling the cracks and divots with patching materials, sealing the concrete floor with an epoxy coating, and finishing with an aliphatic urethane topcoat.

During this process, colors and dyes can also be added to the concrete substrate to give the slab a different look.

Benefits of Grind and Seal Concrete Floors

One of the major benefits of grind and seal flooring is that it allows for a more consistent appearance when compared to polished concrete. This is because the final appearance of the floor is based on the topical coating that is applied to the concrete, so it is not reliant on the existing cosmetic profile of the concrete slab.

Grind and seal flooring is also better suited for facilities that deal with grease, oil stains, and spills. This is because a chemical-resistant coating can be applied on top of the concrete substrate, which allows for easy clean-up. The most popular reason why grind and seal floors are better than polished concrete flooring is that it is more cost-effective. Grind and seal flooring is less labor-intensive and costs significantly less than polished concrete.

With these advantages, it is highly recommended that you have an epoxy flooring contractor insist on your decision and explain the pluses and minuses of both systems.
