NIGP 31530: Coatings, Protective (for Masonry Including Concrete Floor)

NIGP 31530 Coatings, Protective (For Masonry Including Concrete Floor) is an Item code under which state and local governments procure protective coatings, sealants, and floor finishes for masonry, concrete, and related surfaces—most recently sourced through competitive bidding for epoxy floor systems, water tank exterior coatings, gym floor refinishing, and concrete sidewalk and pad installation work. Activity spans airport restroom remodels with brand-specific epoxy application, wastewater treatment facility clarifier recoating, and municipal facility flooring systems, indicating demand across transportation, utilities, public works, and education sectors.
