What is used to produce a slip-resistant surface on concrete?

1. Brooming

2. Sealing

3. Texturing

4. Grinding

The correct answer is: Brooming

Brooming is a technique employed to create a slip-resistant surface on concrete. This method involves using a broom to drag across the surface of freshly poured concrete before it sets. The brooming process introduces fine grooves and textures into the concrete, significantly enhancing traction. This is particularly important for outdoor surfaces like patios, walkways, and driveways, where moisture can create slippery conditions. While sealing can protect concrete by adding a layer that prevents stains or water intrusion, it does not inherently create a slip-resistant texture. Texturing can refer to various processes that can alter the surface finish but may not always guarantee that the surface will be slip-resistant. Grinding, on the other hand, is typically used to smooth out uneven surfaces or remove unwanted material but does not necessarily create a slip-resistant texture like brooming does. Therefore, brooming is the recognized method specifically aimed at achieving a slip-resistant surface on concrete.
