24 Hour flood test. Failure?
I just completed the flood test. It ended up being just over 48 hours. Is the discoloration (lighter green area) near the drain a failure of the hydroban? Should I apply another layer of hydroban to the floor and retest? The water level didn’t drop beyond what I would expect to be evaporation but I’m concerned this could lead to future problems.

Thank you so very much for the reply. I will let it dry tonight and continue to inspect for any loose or peeling areas in the morning.
My neurosis got the best of me and I couldn’t help but start to investigate around the drain tonight. I found a very small piece of sheet membrane on the lip of the drain that did not get covered in hydroban. This is where I believe the moisture was wicked up by the felt. Ugh.
