What process would be used on concrete to produce a nonslip surface?

Producing a nonslip surface on concrete is effectively achieved through the process of brooming. Brooming involves the use of a broom or a brush to texture the surface of the concrete before it sets completely. This creates a series of small grooves and ridges that enhance grip, making the surface safer to walk on, particularly in conditions where it might become slippery, such as when wet.

In contrast, troweling smooths the surface to a fine finish, which is great for aesthetics but does not provide the texture needed for slip resistance. Screeding is primarily used to level and shape the concrete before it begins to harden, ensuring a flat surface, and floating is the method of smoothing out the surface of the concrete to remove imperfections. While these techniques are essential for the overall finish of the concrete, they do not contribute to creating a nonslip surface like brooming does.
