This recommended practice sets forth guidelines for application of quality coating systems to properly prepared concrete surfaces.

Concrete is used and protected by protective coatings in power facilities, chemical processing plants, pulp and paper mills, petrochemical plants, water and wastewater treatment plants, food and beverage plants, and mining operations.

When providing corrosion protection for concrete substrates, considerations must be given to liquid organic chemical-resistant coatings and their proper application and inspection. Concrete, unlike steel, is not a predictable uniform substrate. Concrete is very porous and in many industrial exposures is likely to absorb chemical contamination as it absorbs water, which can cause spalling and eventually loss of structural integrity. Concrete frequently provides structural support for steel in industrial applications; it is also used for catch basins, troughs, machinery mounts, spill containment, and immersion service.

 1.1 The scope of this recommended practice is to set forth guidelines for the selection and installation of liquid organic coatings to be used over concrete exposed to immersion conditions and severe chemical splash and spillage.
