Make your floors safer, and better to look at.

Installing polished concrete or epoxy on your clients’ floor provides a sleek finish and durability at the same time. While polished concrete and epoxy are relatively simple to install, there are essential steps in the process that, if ignored, can ruin all your hard work. Sometimes it’s the uneven ground that the concrete is sitting on top of, sometimes there’s issues during installation. Either way, uneven concrete is one of the most common ways that concrete flooring can go wrong. Concrete leveling is an essential skill to learn in any flooring business dealing with concrete.

Learning how to level concrete is a relatively easy fix for an incredibly frustrating problem. Uneven concrete can impair foot and vehicle traffic, and it affects the cosmetic quality of the finished concrete surface. As a result, it lowers the efficiency of whatever work needs to be done on your clients’ floor and can impact your, and your clients’, business.

Why You Need to Learn How to Level Concrete

There are several reasons why a flooring contractor would want to level concrete as a first step on site. Probably the most important is that installing any system, whether its epoxy or polished concrete, on top of uneven concrete is a recipe for the failure of the system. Working on uneven concrete ensures that the installed system will also be uneven.

There are also safety and efficiency issues that arise with concrete that isn’t level. Protecting your technicians from possible safety hazards is incredibly important when working in flooring. An uneven floor finish will also impede future foot and vehicle traffic. On top of all these practical concerns, it’s also unsightly and will affect the final look of the finished floor.

Step-by-Step Guide: Concrete Leveling

Whether your client wants epoxy or polished concrete, you need to learn how to level concrete before installation. Help save your business money & labor time by getting it right the first time. Here is a step-by-step guide on how to level concrete:

Step One: Identify the Low Spots

The first step in leveling concrete is identifying where the low spots are. Take a look at your concrete floor and identify any areas that are lower than the rest. These areas will need to be filled in with a self-leveling compound.

You can identify it either by eye, if the low area is large and noticeable enough, or using a large level to be thorough. When you identify the low areas, it also helps you understand what solution your floor will need.

Step Two: Apply the Concrete Leveling Compound

Once you’ve identified the low spots, it’s time to apply the self-leveling compound. This compound can be applied with a trowel or squeegee. Simply apply the compound to the low spots and then smooth it out.

Step Three: Leave it to Dry

After you’ve applied the self-leveling compound, all you need to do is wait for it to dry, just as any other system installation. This usually takes around 24 hours. Once it’s dry, the compound will slowly spread out and fill in any low spots on the floor.

Step Four: Finish with a Grinder (optional)

If your concrete floor is still uneven after applying the self-leveling compound, then you may need to use a grinder. The grinder will remove any high spots on the floor and leave behind a smooth surface.

Step Five: Seal the Floor / Install Epoxy

Once the floor is level, it’s time to seal it with a concrete sealant. This will protect the polished concrete from water and dirt damage and will keep it looking its best for years to come. You can also install epoxy onto your newly leveled concrete floor.
