Diamond Polished Concrete

What is Diamond-Polished Concrete?

Diamond-polished concrete is a method of refining and enhancing the appearance and functionality of concrete floors. It involves using diamond abrasives at various grit levels to grind and polish the surface.

This extensive process removes imperfections and reveals the natural beauty of the concrete, creating a sleek, mirror-like finish that can mimic the appearance of polished stone or terrazzo.

Cost of Diamond-Polished Concrete:

The cost can range from $3 to $8 per square foot. The cost of diamond-polished concrete varies depending on several factors, including the area’s size, the existing concrete’s condition, the desired finish level, and regional pricing variations.

While initial costs may be higher than traditional flooring options, the long-term benefits and durability of diamond-polished concrete make it a worthwhile investment.

Steps to Diamond Polish a Concrete Floor:

Achieving a diamond-polished concrete floor involves a meticulous step-by-step process. While it is recommended to hire professionals for optimal results,

here is a general guide to the process:

■ Remove existing coatings,
which might involve scarifying.
■ Patch-scaled or spalled areas in the floor.
■ Seal cracks and joints with semirigid epoxy.
■ Perform a 30- or 40-grit metal-bonded diamond grind.
■ Apply sodium silicate to harden concrete.
■ Grind with 150-grit metalbonded diamond.
■ Grind with 300-grit metalbonded diamond.
■ Polish with 800-grit resinbond diamond.
■ Polish with 1000-grit resinbond diamond.
■ Polish with 1500-grit resinbond diamond.
■ Finish with a 3000-grit resinbond diamond polish.
■ Place penetrating sealer for additional stain resistance

Preparation: The first step involves preparing the concrete surface by patching any cracks or flaws, removing existing coatings, and ensuring a clean and debris-free floor. Proper preparation sets the foundation for an impeccable finish.

Floor Grinding:

  • Grind with a 150-grit metal-bonded diamond.
  • Grind with 300-grit metal-bonded diamond.

Floor grinding is the key step in the diamond polishing process. It begins with coarse diamond abrasives to remove imperfections and level the floor. The grit size gradually decreases to achieve a smooth and even surface. Wet grinding is typically preferred to reduce dust and prolong the longevity of the diamond tools.

Honing and Polishing:

Once the grinding process is complete, honing the floor is the next step. Honing further refines the surface by using finer diamond abrasives.

This step removes any remaining scratches or marks left by the initial grinding and prepares the floor for the polishing process.

Honing also creates a slightly more matte finish, which can be preferred for specific design aesthetics.

Sealing the polished floor:

After honing, the final stage involves polishing the floor with fine-grit diamond abrasives. This process enhances the shine and clarity of the surface, creating a glossy, mirror-like finish. The number of polishing passes depends on the desired level of sheen, ranging from a satin finish to a high-gloss shine.

Protecting and Maintaining: To protect the polished surface from stains and wear, a penetrating sealer is applied.

This sealer fills the microscopic pores of the concrete and provides additional resistance to spills and contaminants.

Different sealers can offer various levels of sheen and enhanced durability. Regular maintenance includes sweeping and occasional damp mopping to keep the diamond-polished floor in optimal condition.

Benefits of Diamond-Polished Concrete:

Enhanced Durability:

Diamond-polished concrete floors are highly durable and resistant to wear and tear. The grinding process removes the top layer of the concrete, eliminating surface imperfections, and exposing a fresh and strong layer. The polished surface can withstand heavy foot traffic, making it an ideal choice for both residential and commercial applications

Increased Aesthetic Appeal: One of the primary reasons for choosing diamond-polished concrete is its visually stunning appearance. The polished finish adds a touch of elegance to any space, enhancing the overall aesthetic appeal. The reflective surface can brighten up the area by maximizing natural and artificial lighting, making it especially desirable for homes and commercial settings.

Low Maintenance:

Unlike traditional flooring options, diamond-polished concrete requires minimal maintenance. Its smooth surface prevents the accumulation of dust, dirt, and allergens, making it easy to clean and maintain. Regular sweeping and occasional damp mopping are usually sufficient to keep the floor looking its best. Furthermore, its resistance to stains and spills makes diamond-polished concrete an excellent choice for areas prone to spills, such as kitchens and garages.


Compared to other flooring options, diamond-polished concrete offers excellent value for money in the long run. Its durability and longevity can significantly reduce the need for repairs or replacements, resulting in cost savings over time.

Moreover, its low maintenance requirements translate to reduced cleaning expenses, making it an economical choice for homeowners and businesses alike.
