UltraZap Hydro Stop is the 1kg leak-stopping product in the Hydro Seal waterproofing range. It’s made to stop and seal leaks in ponds, fish tanks, aquariums and other wet structures, so a weeping joint or cracked patch can be dealt with before it turns into a full re-seal. The small size handles the patch job, leaving the larger Hydro Seal buckets for whole-pond work.

Good to know:
– 1kg size for small repairs and patch jobs
– Stops and seals leaks on wet surfaces
– Part of the UltraZap Hydro Seal waterproofing range
– Pair it with Hydro Seal buckets for full re-seals
