Properly Using a Floor Grinder

A floor grinder is a perfect tool for leveling cleaning, polishing, and leveling concrete floors. Floor grinders are made up of horizontal discs which rotate to finish off rough surfaces and smooth sharp edges. Diamond bits in a disk grind the floors to get the desired level of shine.

If you want to give your house a makeover, you need to learn how to properly use a floor grinder. There are two types of floor grinders, either traditional large and bulky models or the newer, smaller handheld models. Both achieve the same result, but each option requires different skills. Handheld models are typically used for worktops, while the traditional model is used for patios and floors. 

Use of a Grinder

The function of a floor grinder is to remove a thin layer from the floor’s surface to polish it correctly. The grinder will also remove minor stains and blemished. The amount of polishes required for the final finish depends on the current state of the floor.

Methods for Using the Floor Grinder

Grinders can be used in both dry and wet conditions. The wet method uses water to cool off the diamond grits while removing any dust. Water will serve as a lubricating liquid, reducing friction and extending the life of the tools; however, it will definitely leave a mess.

Using the dry method, the machine polishes the floor while individual containers in the grinder hold the dust. The best option is to combine the two processes. The dry grinder method is used to remove any imperfections, while the wet way is to obtain a shiny and mirror-like floor.

Preparing the Grinder

On a floor grinder, there are two types of wheel settings. One is used for transporting the tool, while the other is for the actual grinding process. Move the grinder to wherever you need to use it and ensure that the right setting is on to start grinding, then turn on the motor. At this stage, the polishing disks do not touch the floor. As you feel the machine reaches its total revs per minute, set the grinder on the floor. Move the grinder from left to right.


Go ahead with the dry method. Move the floor grinder from side to side, avoiding circular motions so that you don’t end up making swirls on the floor. Continue the grinding until you get a consistent floor level with all irregularities removed. Examine the blocks to ensure they are even. Replace the grinding blocks gradually and use a coarser grinding block and switch to finer ones later while polishing the floor.
