Flooring Terminology

Concrete Grinding

This is a generic term used to describe several types of services using different types of machines, processes and abrasives. It is performed by a specialty contractor, like Jones Tile, that has experience with the various types of equipment.

Scarrifying

Scarrifying is the outcome of using a machine called a scarrifyer rotating a steel drum with small shafts at an extremely high revolution. Each shaft holds a carbide or steel cutter that rotates loosely on the shaft and “chips” away at the concrete. This method is best used to remove concrete fast and aggressively.

Milling

Milling describes the process of removing concrete with a scarrifyer. Typically, the Jones Tile expert will mill down the edge of a concrete surface to make it even with the adjacent surfaces.

Scabbling

Scabbling is performed with a machine called a Scabblier. It operates by pounding a number of rods, tipped with steel or carbide, down on the concrete surface in rapid succession.

Etching

Etching changes the surface of concrete. It is usually done to prepare the surface for a coating. Etching can be accomplished through scarifying, shotblasting, grinding or even use of an acid. Etching is usually described as “light”, “medium” or “heavy” and describes how much concrete is being removed from the surface and the final appearance.

Coating Removal

Coating removal is the process of removing the top layer or applied coating from an existing concrete surface. This can include paint, lacquers, sealers, self-levelers or thick substances such as epoxy or concrete.

A variety of methods can be used in coating removal such as scarifying, grinding, scabbling, shotblasting or even use of an acid. The best method to use depends on the type of coating to be removed.

Shotblasting

Shotblasting is a one step system that strips, cleans, and properly etches concrete floors. The cleaning head has a completely enclosed centrifugal blast wheel. As the wheel spins metallic abrasive (shot ) is fed into its center and thrown from its blades to blast the floor surface. The unit then separates the contaminants to an attached dust collector and automatically recycles the shot.
