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. Premium lustrous white pebbles along with a small amount of glossy black pebbles make up this finish. The watercolor, in most cases, falls into a medium-dark blue hue.
