The existing raised patio here is around 20 years old. It was worn and cracked. We cleaned thoroughly and then applied epoxy stitching to hold cracks together. Then laid down fiber tape to keep the cracks from mirroring through to the new surface.
We then troweled down an overlay product and stamped that with a mixture of Italian and Belgian slate mats. Colored with dominantly grays with just a splash of brown here and there as per customers wishes. Finished off with acrylic sealer and slip resistant additive.
