CoraScape Powder is a natural oolitic sand for use when bonding dry limestone rocks to make strong and invisible joints. Use with CoraScape Bonder to form ultra-strong joints instantly. Simply fill the gap between rocks with CoraScape Powder and then drip CoraScape Bonder into the powder, allowing it to soak in. A reaction produces heat and forms an instant, very solid and strong bond. Additional layers of powder can be added and solidified with the bonder. As soon as the joints are hardened the aquascape can be placed into the water.
