§ Capability map
Four chemistry families, indexed against every stage of your line.
Nordgyp Labs is at the technical-record stage. This map describes the chemistries we can formulate and source with partner suppliers; specific dosages, targets and grades are derived from bench and line trials on your own stucco and water, not quoted from a catalog.
