Reef Putty – Black (200 g / 7 oz)

Overview

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.

Key Features

• 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

Suggested Uses

• 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

Specifications

• Net Weight: 200 g (7 oz)

• Color: Black

• Type: Two-part hand-kneadable epoxy putty (resin + hardener)

How to Use

1. Turn off flow near the work area for a few minutes.

2. Slice equal parts; knead until the color is uniform.

3. Press firmly onto clean surfaces; hold 30–60 sec to tack.

4. Restore flow after 10–15 min; avoid heavy handling until cured.

5. Temporary skimmer overactivity/cloudiness may occur—use carbon if needed.

Tips

• 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.
