Fast-bonding sealant designed for wet surfaces and pool-side fixes.

Stronger Than the Reef Itself​

Developed with inspiration from the natural chemistry of mussel adhesive, SeaTak® is built for one mission: to make global coral restoration possible at scale.

​Funded by NOAA and trusted by researchers and hobbyists alike, it’s the adhesive of choice for reefs, aquariums, and underwater projects where performance matters most.
  • Reef restoration ready: Designed to secure coral fragments and structures with long-lasting strength.
  • Safe & sustainable: Fume-free and non-toxic once cured, protecting water quality and marine life.
  • Effortless to use: No mixing, no ballooning, no skinning — just apply and let water do the work.
  • Built for the toughest jobs: Tackier, longer-lasting, and more flexible than cyanoacrylate or epoxy.
  • Dual purpose: Equally effective for reef projects and aquarium aquascaping.

With its water-initiated cure and strong initial tack, SeaTak® delivers results in conditions where other adhesives fail.

SeaTak® in Action

From bonding corals to securing 3D reef structures, these real-world deployments show how our marine sealant performs in the environments it was designed for. Strong, reliable, and reef-safe, SEATAK is helping divers and restoration teams build a stronger future beneath the waves.

How to Use SeaTak®

1. Prepare Surface

Clean and rough up the surface if necessary. The surface does not need to be dry, but it should be free of loose debris.

2. Apply Adhesive

​Use a caulk gun or squeeze directly from the tube. Apply deliberately — you may need more than you think. A bead of about ¼"–½" works well for most jobs.

3. Let It Set

​PoolTak reacts with moisture, so curing begins immediately. It will form a skin as it starts to set. Allow 2–3 hours for initial set and 24 hours for full cure.

4. Clean Up

​Uncured adhesive can be wiped away with acetone or rubbing alcohol. Once cured, it must be removed mechanically (sanding or chipping).
