ecoFINISH Aquabright excessive peeling

[Dorner]

About 3 years after my pool was resurfaced with Aquabright (for the second time) it started peeling. I have not even contacted the installer because I have no desire to hope for three is a charm. Now the problem is how do I get it resurfaced with another product. I had one well reviewed installer come to assess the pool. He had never heard of aquabright but felt confident that he could get the pool chipped out. Hoping that someone else has had success
resurfacing with a different product after ecofinish aquabright and give some direction.

Full chip out of the underlying plaster.

AquaBright is just a thin polymer overlay on top of plain plaster. If you have the underlying plaster chipped out, the AB goes with it.

Plaster can either be air-chiseled out (use ONLY flat blades, not pointed chisels) OR it can be sand blasted down to the gunite shell (extremely messy) OR it can be hydroblasted (water at 20,000-40,000 psi) down to the gunite.

What you absolutely don’t want them to do is just do partial chipping, rough up the aquabright, add a bond coat and then skim coat a thin layer of plaster on. That would be a recipe for disaster. Remove EVERYTHING down to the gunite shell and start over with new plaster.

Thank you, I really appreciate the information
