IG Gunite in poor shape.
I bought the UltraGuard 6000 with bond coat, then asked Windfix for some advice concerning surface prep. We seemed to share the same issues of flaking plaster after acid washing, etc. Windfix was VERY helpful (thank you) with some tips regarding equipment and surface details.

I've taken the advice to grind and smooth the surface very seriously and it is taking a long time. I am almost smooth and will be patching holes in paster which went to concrete with the mortar mix this week. I will also be smoothing the floor with the suggested leveler as found in the FAQs at poolrestoration.com. The unopened buckets of UltraGuard await completion of the surface prep. My goal is a tight smooth surface on which to apply the bond coat.

I will post photos and document the process in more detail for those who might choose to embark on the UltraGuard journey.
