What Is Concrete Grinding And Why Is It Important?

What Is Concrete Grinding?

Concrete Grinding is the use of an abrasive tool, that cuts the top layer of concrete in order to remove imperfections and leave a smooth finish. In situations where concrete surfaces are not levelled, are extremely scratched or are covered in coatings, such as paint, epoxies, waterproofing or glue we can grind the concrete to an acceptable state.

Grinding Concrete can be done either wet or dry. At Concrete Grinding Sydney, we prefer to Grind under dry conditions to reduce the negative impacts of the dust on our health.

What Is Concrete Grinding Used For?

Grinding Concrete removes all imperfections and inconsistencies in the concrete, resulting in a smooth and usable surface. Old and damaged concrete surfaces can be restored to their former glory and used for years and years to come.

Concrete Grinders are commonly used to level off a slab, remove paints, glues, epoxies, stains, and other coatings from concrete in order to prepare for new floor coverings, and coatings, or to polish concrete surfaces to perfection. Concrete Grinding provides good adhesion for new flooring systems, coating or toppings.c

Concrete Grinding is important before installing almost any flooring system (apart from the carpet) floorboards, tiles, vinyl, lino, slate, epoxy, paint, waterproofing membranes, parquet, floor levelling agents, etc will all require Concrete Grinding before installation.

Why Is Concrete Grinding Important?

Prior to floorboards or tiles being installed, the concrete beneath can be rough and uneven and even have paint or epoxies on it. Making installing various flooring on top of it can be difficult. Once grinding has taken place and the smooth surface is revealed installing any alternative flooring option is easy.

Preparing the floors prior to the application of tiles or hardwood is the single biggest way to ensure the longevity of the floors. It is especially important if the floors are going to be polished, as the quality of the concrete will show through.

Advantages Of Concrete Grinding

RESTORE CONCRETE SURFACES

Concrete Grinding removes all imperfections and inconsistencies in the concrete, resulting in a smooth and usable surface. Old and damaged concrete surfaces can be restored to their former glory and used for years and years to come.

TO REMOVE PAINT, EPOXIES AND OTHER COATINGS

Concrete Grinding removes paint, epoxies, and other coatings from concrete floors. The Concrete Grinder rubs against the top layer of the floor, leaving nothing behind but a smooth, good-as-new surface.

IMPROVES SAFETY

Concrete grinding can enhance safety by transforming a rough and damaged floor into a smooth, hard surface, reducing the risk of injury for homeowners and visitors. Additionally, when applied to driveways, it can create a quieter and more slip-resistant surface for vehicles.

EASILY INSTALL NEW FLOORING SYSTEMS (tiles, floorboards, carpets, etc.)

Once the grinding has been completed and the smooth surface is left, any type of flooring option can be installed with ease. Floor preparation is key to the longevity of any kind of flooring option. 

COST-EFFECTIVE OPTION

Grinding an existing concrete slab is more cost-effective than removing and installing a new one. Additionally, it can save money on the installation of other flooring systems which require a level and even surface for proper installation. Installing tiles or timber over an uneven surface can also be difficult and costly as the installers attempt to make the surface level. By grinding down the concrete to a smooth surface, you can save money in the long run.

What Is A Concrete Grinder?

A Concrete Grinder can come in many configurations, the most common being a hand-held Hand Grinder or hand-held Angle Grinder, but it may be a specialized tool for countertops or worktops. Angle Grinders and Hand Grinders are small and mobile and allow one to work on harder-to-reach areas and perform more precise work.

There are also small, medium, and large walk-behind Concrete Grinders for tackling larger projects, there is even riding on Concrete Grinders for industrial projects.

All concrete grinders use some sort of abrasive to grind or polish such as diamond tools or silicon carbide. The diamond tools used for grinding most commonly are diamond grinding cup wheels, other machines may use diamond segments, mounted on various plates, slide-on diamond grinding shoes, and for polishing are usually circular Resin diamond polishing pads.

The use of diamond attachments is the most common type of abrasive used under concrete grinders and comes in many grits that range from 16 grit to the high thousands, although 3,000 grit is considered by the industry as the highest shine possible to apply to a floor surface.
