This Premium Glowing Mini Pebble Sample Kit contains AGT™ Glowing Mini Pebble samples in all three colors; Emerald Yellow, Aqua Blue and Sky Blue and in both 1/4" & 1/8" sizes. AGT™ High-Performance Glowing Mini Pebbles feature an even longer & brighter glow than our industry-leading ULTRA Grade Glow Stones. The innovative shape of the 1/8" sized glow aggregate was specially designed for pool batch use and homogeneously integrates into all types of pool finishes from DiamondBrite™, QuartzScapes™ and Marbletite™ quartz plaster finishes to PebbleTec™ and StoneScapes™ mini pebble finishes - only to name a few. The 1/4" sized AGT™ Glowing Mini Pebbles were designed for hand-broadcasting onto horizontal surfaces such as pool floors, Baja Shelves and stairs as well as exposed aggregate concrete pool decks, patios and walkways. The shape and size of these glowing mini pebbles are very similar to that found in common pea gravel aggregate so exposed aggregate decorative concrete finishes turn out glowingly amazing!
