Epoxy Coat or Polish Concrete?

Updated: Oct 8, 2021

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 commercial floor, many people know what kind of design they are looking for, but don’t quite know the industry terminology for it.

Grind and seal floors are often times 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 qualities of each prior to having a resinous flooring expert install a flooring system in your commercial facility.

What Is Polished Concrete?

Customers usually ask for polished concrete floors when stating that they would like a concrete floor that is shiny. However, even though the name clearly states that this process

would produce a polished floor, the fact is that oftentimes that is not the case.

Since polished concrete flooring require a very strong concrete base, many times the concrete slab inside your commercial facility simply cannot withstand this process. 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.

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 high gloss performance finish is applied on top.

This process does not work for every concrete surface, and many times the concrete slab does not allow for the proper amount of sheen to be produced. Additionally, this process also takes longer than grind and seal and has a higher failure rate.

What Is Grind And Seal Flooring?

Typically, the shiny concrete floors that you see in commercial facilities are actually 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 grind and seal involves grinding the concrete substrate with concrete grinders, filling the cracks and divots with patching materials, and sealing the concrete floor with either an epoxy or polyurethane topical coating.

During this process, colors and dyes can also be added to the concrete substrate in order to give the slab a neutral, earthy or more colorful tone.

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 actual 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 install grind and seal floors when you are looking for a flooring system that will be shiny, cost-effective and durable for your facility.
