UNS Controlock - Red Brown (Hardscape Bonding Material)

UNS Controlock is a two-part bonding putty for locking hardscape into position. Mix the powder with the included adhesive and it sets into a hard, aquarium-safe fill that holds stone and wood at angles gravity would never allow.The Red Brown tint blends into brown and warm-toned rock — Wolf Stone, Frodo, and most driftwood — so seams disappear instead of announcing themselves as grey blobs. That's the difference between a scape that looks assembled and one that looks found. Color: Red Brown Includes: 60g bonding material, 20g adhesive, tweezers, precision tips Aquarium safe: inert once cured, no effect on pH or livestock Use for: stacking stone, mounting wood, filling and hiding seams Also available in Grey, Brown, and Light Brown to match other hardscape tones.
