Two-part epoxy putty needs no introduction as most of us get covered in it every weekend, but Nyos has launched its own epoxy called Reef Putty. Like other epoxy putties in the hobby, Reef Putty contains two equal parts that you mix together by hand, press down onto your chosen surface, and then leave to harden over time. Just like other putties, you can use it underwater and it comes in two colors when mixed – black, and stone grey. No purple though, to match the “high-level reefing,” company’s corporate colors.
The two parts come in the form of angular bars versus more standard cylindrical sausages, and Reef Putty weighs in at nearly twice the weight of some other popular packs, at 200g, or 7oz. Nyos quotes a processing time of 45 minutes, a setting time of three hours, and that it should be rock solid after 24 hours. We always find a much better bond when using any two-part epoxy dry, like when joining rockwork, but if using underwater that first initial press into the rock is always the best one, and the more you play with it once submersed, the more slimed up and less sticky it becomes. Practice, set it, and forget it, and wear gloves if you don’t want to get it on your skin.
