I am going on 2 months for getting my pool refinished. One thing after another. We are close and the pool guy did the bond coat, but ran out of material before they finished bond coating (see picture). They are saying that because it is down to the gunite shell that it is unnecessary to finish bond coating before plaster. Any opinions? Doesn't feel like much more effort but why would they bond coat 80% of the pool, run out and then use the justification that it is not needed?
