How To Level Concrete Floor High Spots

Many people consider concrete as the best flooring material, given its versatility. It perfectly suits both classic and modern décor for both home and commercial use.

When polished, a concrete floor can be the most beautiful element in interior spaces. The flooring can also last longer than just about any other contemporary flooring material.

These cracks can widen to the point that they may trip you when walking on the floor. Moisture can also seep in, damaging the floor over time.

Leveling Concrete Using Grinding

For an uneven floor, grinding the concrete floor high spots is your only option.

Besides finding the high spots, the major challenge is in knowing when to stop grinding. Problem is there are no means to accurately determine when the desired levelling has been achieved.

Using a heavy-duty grinder

The kind of tool you use in grinding concrete floor high spots determines the quality of your concrete repair.

A walk-behind heavy-duty grinder with diamond blades on the bottom gives great results. But be careful. The blades in this machine cut so rapidly that a small miscalculation may result in a major dent on the surface.

You’ll need to mount a laser receiver on the grinder to signal that it is time to stop grinding.

In using the receiver, first put the grinding machine on a section of the that has the right elevation.  Then adjust the transmitter elevation until the receiver gives an on-grade indication.

After that, your crew can move to each high spot.

Terrazzo machine

Besides the grinder, some concrete grinding crews prefer a terrazzo machine with Carborundum stones. But this is slower than the diamond grinders.

This machine is typically used by concrete grinding professionals. If you opt to do the grinding yourself, it’s best to lease than buy one.

Problem is, you won’t have the level of expertise to deliver a spot-on result. That’s why unless it’s best to leave all concrete grinding work to experts such as Megasaw that have been doing it for well over 20 years.

This dust should not to be toyed with. Exposure to the cement dust can irritate eyes, throat, nose and the rest of the respiratory system. Moreover, if it comes into contact with the skin, it may cause moderate irritation,  cracking or thickening of skin.
