In this section, we'll look at the range of 'surface prep' machines used to remove the top layer of concrete from a slab.

We'll talk about their pros and cons and the finish they produce.

Then we'll focus on grinding machines and examine the different types available and the tooling they use.

The main purpose of concrete grinding is to remove ridges, contaminants and loose material from the subfloor surface.

By removing ridges and imperfections through grinding, you can often reduce the overall cost of preparing the surface for a floor covering.

If you're able to achieve a surface finish smooth enough to allow carpet or vinyl to be laid straight on top, you'll not only avoid the expense of a cement-based skim coat, you'll also save yourself the waiting time for the skim coat to dry.
