Seachem CoralCrete 114 g – Aquarium Epoxy Putty for Secure Coral Placement and Stable Reef Rockwork
Seachem CoralCrete 114 g is a two-part epoxy putty designed to secure corals to rockwork and fuse aquarium rocks together for stronger, more stable reef foundations. It is especially useful when mounting larger colonies of branching coral, positioning large polyp corals, or attaching plating corals to carefully selected areas of a reef aquascape.
Whether building a new reef layout or reinforcing an existing coral placement, CoralCrete offers a practical working window of approximately 5 minutes. Once mixed to a uniform colour, the putty can be pressed around the base or contact point of coral or rock, helping it enter surface pores and grooves for a secure hold. It can be applied both underwater and outside the aquarium before placement.
CoralCrete begins curing in about 5 minutes, becomes hard in approximately 15 minutes, and reaches a full cure within 24 hours. The epoxy is suitable for marine and freshwater aquarium use and is safe for aquarium inhabitants when applied according to instructions. During the curing period, protein skimmers may temporarily over-activate.

How to Use This Aquarium Epoxy Putty
- Wear protective gloves during handling, particularly when skin is sensitive.
- Cut off only the required amount of CoralCrete for the coral or rockwork being secured.
- Place any unused material back into the supplied plastic storage tube.
- Remove the film from the cut portion and knead the two-part epoxy together until the colour becomes uniform.
- Apply the mixed putty to the coral base or rock contact point, either submerged or emerged.
- Press firmly so the putty works into the pores and surface grooves of the coral base or rock.
- Complete positioning promptly, as curing begins in about 5 minutes and the material hardens in approximately 15 minutes.
- Allow 24 hours for the epoxy to fully cure.
Care & Maintenance Tips
- Plan coral placement before mixing, as repositioning becomes difficult once the putty hardens.
- Store unused CoralCrete in its original plastic tube between applications.
- Expect possible temporary over-activation of the protein skimmer while the epoxy cures.
- Keep the container tightly closed and store away from heat, hot surfaces, sparks, and open flames.
- Wear protective gloves and eye protection during use.
- Wash skin thoroughly with water after accidental contact.
- Rinse eyes carefully with water and seek medical attention if irritation persists.
- Use only as directed when applying in an aquarium with livestock present.
