Two-part black epoxy putty for aquascaping and coral mounting. Kneads by hand, sticks underwater, and cures rock-solid so you can secure frags, stabilize rockwork, and hide seams in dark scapes.
Reef-safe once cured; designed for marine & freshwater use
Underwater usable—bonds even in wet/splash zones
Black color blends with dark rock, shadowed joints, and black back panels
Workable for ~5–10 min, initial set in ~15–30 min, full cure ~24 hrs
Adheres to rock, ceramic, glass, acrylic, most plastics, and PVC
Mount SPS/LPS/soft coral frags to plugs or live rock
Lock rocks together to prevent topples or stabilize arches
Hide plumbing holes or cosmetic seams in dark aquascapes
Net Weight: 200 g (7 oz)
Color: Black
Type: Two-part hand-kneadable epoxy putty (resin + hardener)
Curing: Room temp; slight heat during cure is normal
Shelf Life: Store sealed, cool, and dry
Turn off flow near the work area for a few minutes.
Slice equal parts; knead until the color is uniform.
Press firmly onto clean surfaces; hold 30–60 sec to tack.
Restore flow after 10–15 min; avoid heavy handling until cured.
Temporary skimmer overactivity/cloudiness may occur—use carbon if needed.
For frags: a small superglue gel dab on each side of the putty can speed grab (“glue–putty–glue” sandwich).
Roughen smooth spots and remove algae/biofilm for best bond.
Do not use for structural loads beyond typical aquascaping.
