This innovative product line combines regular and small size pebbles. The two pebble sizes interlock and create a tight compaction that gives the finish an even smoother texture than single-sized pool finishes. Glossy black pebbles make up this finish. The watercolor, in most cases, falls into a black bottom dark hue. To set proper expectations and understand more about this product, please watch the overview video and visit our disclaimer page.
