Plain plaster failed at year 6 — full chip-out required
Mottled staining, rough texture, crazing across the shallow end. Owner had been chasing chemistry for 18 months.
Plain white plaster + AZ hard water + high calcium = surface degradation by year 5–7. Not a chemistry problem — a spec problem.
Hydroblast to gunite, re-plaster in Pebble Sheen, rebalance saturation index, install auto-fill to stabilize water level.
AE Standard: pebble interior finish on every new build. No plain plaster, ever.
