This depends almost entirely on the contractor you choose to provide the service.
Stamping concrete can add texture and slip resistance to the surface of the concrete. However, the slip resistance of stamped concrete can vary depending on the design, the type of stamp and the sealer used. Some stamped concrete patterns can be more slip-resistant than others. For example, a broom-finish pattern is generally more slip-resistant than a smooth pattern.
A sealer can also be applied to the stamped concrete surface to enhance the slip resistance. Acrylic sealers are commonly used and can provide a non-slip surface and increase the durability of the stamped concrete. However, it is important to note that the sealer should be appropriate for the stamped concrete and should be applied correctly.
It is also important to note that stamped concrete can be slippery when wet, just like any other concrete surfaces, so it is important to take precautions such as adding slip-resistant additives to the concrete mix, or applying a slip-resistant coating, to increase slip resistance.
In addition, it is important to keep stamped concrete surfaces clean and free of debris, moss, and algae as these can make the surface slippery when wet.
