The coating is a polyurea used inside pipes. It gels in about 3 seconds, making it non self-leveling. The texture is like an orange peel, the perfect substrate for biofilms.

This shit shrinks 1-3% when curing, which in a pipe is exactly what you want. On a big slab, uh, no it will pull towards the center and delaminate from the substrate at the edges.

Plus, applying directly to concrete is a problem. Long story short: Swiss cheese pinhole effect. Already flagged.
Rhino Pipeliner 5000 is not recommended for ponds. It's specialized for trenchless pipe repair, hence its rigidity and 3 second gel time. Other polyureas/polyurethanes are far more stretchable and good for continuous immersion.

Baffled that Rhino itself didn't step in, maybe they did
