Pool and hot tub was plastered on Sunday (after the rain passed). Finished filling it the same night. Went out to check on things this evening and noticed the negative wall of the raised spa had several damp spots.
The negative wall still needs to be finished as I have yet to install the stacked stone. Inside and outside of the spa was coated with two coats of MasterSeal 581. Damp spots seem to be at the same elevation as the spa jets. When gunite was sprayed they didn't do a good job of getting between the forms and the pipes. After the forms were stripped some of the more problem areas were chipped out in this area and patched with grout.
Is this weeping through from the positive edge? Could a pipe leak at atmospheric pressure cause this many damp spots? Pics were taken on opposite walls so I am leaning away from the pipe leak. What are my options? A third/fourth coat of the MasterSeal on the negative edge? Chip out and re-grout these areas?
