Usage
Designed for a variety of reef‑keeping applications, this epoxy putty excels at securing coral fragments to frag plugs, attaching decorative rocks, and reinforcing live rock structures. Its quick‑setting nature allows hobbyists to position pieces precisely before the material hardens, reducing the need for prolonged holding or clamping. The putty can be molded by hand to fill gaps or create custom shapes, making it ideal for both novice aquarists and experienced reef builders seeking to craft intricate aquascapes.
When using the putty, it is recommended to clean all surfaces with a marine‑safe alcohol solution to remove any algae, slime, or debris that could interfere with adhesion. Apply a small amount of the putty to the desired area, press the components together, and hold them in place for a few seconds while the initial set occurs. After the five‑minute set, the bond becomes firm enough to support the weight of most coral fragments and rocks. The fully cured epoxy is water‑resistant and will not leach harmful substances into the tank.
