Is polished concrete slippery?

Polished concrete surfaces are not inherently slippery. The slipperiness of a polished concrete surface depends on several factors, including surface texture, coefficient of friction, moisture content, and contaminants.

Contrary to common belief, a highly polished surface does not automatically mean a slippery surface. The level of glossiness can be adjusted during the polishing process, allowing for customization of the surface’s traction. Polished concrete can be tailored to different levels of sheen, ranging from low to high gloss, to meet specific slip resistance requirements.

Moreover, polished concrete surfaces typically have a higher coefficient of friction (CoF) due to their tight and compact nature, which enhances slip resistance. The CoF measures the force required to move an object across a surface and indicates the slipperiness of the material. Polished concrete’s smoothness and composition contribute to its relatively high CoF.

Moisture content on any flooring surface can increase the risk of slipperiness, including on polished concrete. However, when properly maintained and cleaned, polished concrete surfaces are not more prone to become slippery when wet compared to other flooring types like ceramic tiles or vinyl. Regular cleaning and prompt removal of liquid spills are necessary to maintain a safe walking surface on polished concrete.

Contaminants such as oil, grease, or other substances can affect the slip resistance of any flooring surface, including polished concrete. If not cleaned or addressed promptly, these contaminants can create a slippery surface. Regular cleaning and maintenance practices are essential to prevent the accumulation of contaminants and ensure a safe and slip-resistant polished concrete surface.

It is important to note that slip resistance can vary between different types of polished concrete and the specific conditions in which they are installed. Therefore, when considering polished concrete for a particular space or application, it is recommended to consult with a professional who can assess the slip resistance requirements and customize the polishing process accordingly.

Slip Resistance Testing

To evaluate the slip resistance of different surfaces, including polished concrete, various standardized tests are commonly used. The two primary tests are:

  1. Static Coefficient of Friction (SCOF) Test: This test measures the amount of force required to initiate movement between a sled and a surface. A higher SCOF value indicates a greater resistance to slipping.
  2. Dynamic Coefficient of Friction (DCOF) Test: This test measures the amount of force required to maintain movement between a sled and a surface. A higher DCOF value suggests better slip resistance.
