No, black porcelain paving slabs do not get slippery when wet. They come with an R11 slip rating, which means they have a high level of slip resistance, making them safe for use in wet conditions. This rating ensures the surface provides good grip underfoot, even when exposed to rain or water.
This makes black porcelain paving a reliable choice for outdoor areas like patios, paths, and pool surrounds, where safety in wet conditions is important.
