How polished concrete is achieved
The process of polishing concrete involves grinding the surface with a series of diamond-tipped discs. This process removes any imperfections in the concrete and creates a smooth, reflective surface. Once the concrete has been ground, it is sealed with a penetrating sealer to protect it from stains and moisture.

Steps involved in polishing concrete
The process of polishing concrete involves the following steps:
- Surface preparation: The first step is to prepare the concrete surface for polishing. This may involve repairing any cracks or damage, and grinding down any uneven areas.
- Grinding: The next step is to grind the concrete surface using a series of diamond-tipped discs. This process removes any imperfections in the concrete and creates a smooth, reflective surface.
- Honing: Once the concrete has been ground, it is honed using a finer grit diamond disc. This process further refines the surface and gives it a more uniform finish.
- Polishing: The final step is to polish the concrete surface using a very fine grit diamond disc. This process creates the high shine that is characteristic of polished concrete.
- Sealing: Once the concrete has been polished, it is sealed with a penetrating sealer to protect it from stains and moisture.
Equipment and tools used for polishing concrete
The following equipment and tools are typically used for polishing concrete:
- Concrete grinder: A concrete grinder is a large machine that is used to grind the concrete surface. It has a rotating head that is equipped with diamond-tipped discs.
- Honing machine: A honing machine is a smaller machine that is used to hone the concrete surface. It also has a rotating head, but it is equipped with a finer grit diamond disc.
- Polishing machine: A polishing machine is the smallest of the three machines. It is used to polish the concrete surface to a high shine. It has a rotating head that is equipped with a very fine grit diamond disc.
- Dust containment system: A dust containment system is used to collect the dust that is generated during the polishing process. This is important to protect the health of the contractor and the occupants of the building.
Surface preparation for polished concrete
The following steps are typically taken to prepare the concrete surface for polishing:
- Remove any existing flooring: If there is any existing flooring on the concrete surface, it must be removed. This may involve scraping, chipping, or grinding.
- Repair any cracks or damage: Any cracks or damage in the concrete surface must be repaired. This can be done using a variety of materials, such as concrete patching compounds, epoxy resins, or polyurethane sealants.
- Grind down any uneven areas: If the concrete surface is uneven, it must be ground down to create a smooth surface. This can be done using a concrete grinder.
- Clean the surface: Once the concrete surface has been prepared, it must be thoroughly cleaned. This can be done using a pressure washer or a vacuum cleaner.
- Always wear appropriate safety gear when polishing concrete, such as a dust mask, safety glasses, and gloves.
- Be careful not to over-grind the concrete, as this can damage it.
- Use a dust containment system to collect the dust that is generated during the polishing process.
Types of Polished Concrete:
The type of polished concrete finish you choose depends on the desired look and feel for your space. The four most common types of polished concrete finishes are:
Full aggregate exposure
This finish exposes the full aggregate in the concrete, giving it a rustic, natural look. It is the most aggressive type of polish and requires the most concrete to be removed. This finish is often used in commercial and industrial spaces, but it can also be used in residential spaces to create a unique and stylish look.
Partial aggregate exposure
This finish exposes some aggregate in the concrete, but not all of it. This gives the concrete a more polished and refined look than full aggregate exposure, but it still retains some natural beauty of the aggregate. Partial aggregate exposure is a popular choice for both commercial and residential spaces.
Salt and pepper finish
This finish exposes a small amount of the aggregate in the concrete, creating a speckled effect. This is the most subtle of the four finishes and gives the concrete a clean, modern look. Salt and pepper finish is a popular choice for both commercial and residential spaces.
This finish does not expose any of the aggregates in the concrete. It is the most polished of the four finishes and gives the concrete a smooth, uniform look. Cream finish is a popular choice for commercial spaces, but it can also be used in residential spaces to create a luxurious and elegant look.
Polished Concrete Finishes:
Glossy vs. matte finishes
Polished concrete finishes can range from glossy to matte. The gloss level is determined by the number of times the concrete is polished and the type of polishing pads used. Glossy finishes are more reflective and show more detail in the aggregate, while matte finishes are more subdued and less reflective.
- More reflective and show more detail in the aggregate
- Can make a space feel more open and airy
- Easier to clean
- Can show more scratches and imperfections
- Can be more slippery
- More subdued and less reflective
- Can hide scratches and imperfections better
- Less slippery than glossy finishes
- Can make a space feel smaller and more enclosed
- Can be more difficult to clean
Staining and dyeing options
Polished concrete can be stained or dyed to change its color. Stains penetrate the concrete, while dyes coat the surface. Stains are more durable and resistant to fading, while dyes are easier to apply and offer a wider range of color options.
Color choices for polished concrete
Polished concrete can be stained or dyed to almost any color. Popular colors include:
- Natural gray
- Light brown
- Dark brown
Maintenance and Care tips:
- Clean spills immediately. Spills can etch the surface of polished concrete if they are not cleaned up quickly.
- Use mats at entrances and doorways. This will help to trap dirt and debris before it is tracked onto the floor.
- Avoid using rubber-backed mats. Rubber can leave marks on polished concrete.
- Protect the floor from furniture and appliances. Use felt pads or furniture coasters to prevent scratches and dents.
- Have the floor professionally polished and resealed every 1-2 years. This will help to maintain the shine and durability of the floor.
