What is polished concrete?
Polished concrete is hardened and densified concrete brought to a shine using diamond abrasives. The design options for polished concrete are endless, including scoring patterns, colors, embedded aggregates, stencils, and different sheen levels. Polished concrete is popular in commercial applications due to its low maintenance and high durability.
What are the finish levels for polished concrete?
The standard finish levels for polished concrete are:
- Class I: Low Reflectivity, 400 grit - The lowest finish level, this results in a surface that exhibits a low sheen level.
- Class II: Medium Reflectivity, 800 grit - This results in a surface that exhibits a moderate level of specular reflectivity.
- Class III: High Reflectivity, 1500 grit - This results in a surface that exhibits a high level of specular reflectivity.
- Class IV: Highest Reflectivity, 3000 grit - The highest level of reflectivity that exhibits an incredibly high level of reflectivity.
What are the grades for polished concrete?
The standard grades for polished concrete are:
- Grade I: Cream Finish - Typically, a Grade I finish only exposes the sand particles in the concrete floor. This is a honed and polished concrete surface.
- Grade II: Salt & Pepper Finish - Riverbed Concrete's standard finish, this exposes a spattering of aggregate in the concrete floor. This is a hones and polished concrete surface.
- Grade III: Aggregate Finish - A Grade III finish exposes the greatest amount of medium and large aggregate in the concrete floor. This is a cut surface.
What is the polished concrete process?
- Remove existing coatings (for thick coatings, use a 16- or 20-grit diamond abrasive or more aggressive tooling specifically for coating removal)
- Grind with a 30- or 40-grit metal-bonded diamond.
- Grind with an 80-grit metal-bonded diamond.
- Grind with a 150-grit metal-bonded diamond (or finer, if desired).
- Apply a chemical hardener to densify the concrete.
- Polish with a 100- or 200-grit resin-bond diamond, or a combination of the two.
- Polish with a 400-grit resin-bond diamond.
- Polish with a 800-grint resin-bond diamond.
- Finish with a 1500- or 3000-grit resin-bond diamond (depending on the desired sheen level).
- Optional: Apply a stain guard to help protect the polished surface and make it easier to maintain.
What are the advantages of polished concrete?
Cost savings: Using the slab on grade as the finished floor surface is more cost effective, maintenance costs are lower
More resistant to high foot traffic.
Less maintenance and longer service life: Polished floors are easy to clean, requiring only occasional damp mopping. They also eliminate the need for messy waxes or coatings as well as the associated labor, time, and expense to apply them. The glossy surface of polished concrete resists the marks of forklift truck tires and staining from oil and chemical spills.
Resistance to moisture transmission issues: Polished concrete allows the floor to breathe and eliminates issues that arise with other flooring materials that seal off the concrete.
High light reflectivity: Important for office buildings, hotels, restaurants, and other public facilities that want to project a bright, clean, professional image. Also saves energy by reducing artificial lighting requirements.
Is a sustainable flooring alternative: Polished concrete does not require hazardous coatings, cleaners or adhesives.
