What is Architectural Paint? A Breakdown of Performance and Options

Architectural paints include interior and exterior paints, primers, sealers, varnishes, and stains. These products are applied onsite to residential, commercial, institutional, and industrial buildings and are typically sold in five-gallon containers. Architecture paint does not include industrial maintenance (IM) coatings, special-purpose coatings, or allied paint products.

What are Industrial Maintenance Coatings?

Industrial maintenance (IM) coatings include paints that are factory-applied to manufactured goods as part of the production process, like cars, appliances, furniture, beverage cans, machinery, and electrical equipment. Architectural and Industrial Maintenance (AIM) coatings distinguish IM coatings from other architectural coatings based on the manufacturer’s recommended product use. Manufacturers must label IM coatings as follows:

  • Not intended for residential use
  • For industrial use only
  • For professional use only

Industrial Maintenance (IM) coatings include primers, sealers, undercoats, intermediate coats, and topcoats. They are recommended and formulated for application to substrates exposed to one or more of the following severe environmental conditions in a commercial, industrial, or institutional setting:

  • Chronic or acute exposure to caustic, corrosive, or acidic agents. Also, exposure to chemicals, chemical fumes, or chemical mixtures
  • Immersion in water, wastewater, or chemical solutions (aqueous and non-aqueous solutions) in addition to chronic exposure of interior surfaces to condensation
  • Repeated exposure to temperatures higher than 120 °C (250 °F)
  • Frequent heavy abrasion, including mechanical wear and repeated scrubbing with industrial cleaners, scouring agents, or solvents
  • Exterior exposure of metal structures and structural components

What are Special-Purpose Coatings?

Special-purpose coatings include high-performance maintenance coatings, marine paints, automotive refinish paints, transportation markings, and aerosol paints, often used for enhanced durability.

What are Allied Paint Products?

Allied paint products include paint and varnish removers, paint brush cleaners, putties, paint thinners, pigment dispersions, and frit (ground glass or glaze).

Sto Elastomeric Coatings

The high elongation properties of Sto Elastomeric Coatings decorative coatings bridge hairline cracks caused by thermal changes in the substrate, tremendously improving a building’s appearance. In addition, Sto Elastomeric coatings resist water absorption from wind-driven rain and direct contact with vertical surfaces. They also offer superior UV and mold resistance.

Sto Primers

Applying Sto Primers to masonry, concrete, plaster, continuous insulation systems, drywall, or base coats before the Sto finishes and coatings will promote uniform substrate absorption and help maintain adequate dry film thickness. It can also extend the topcoat coverage, which helps lower the overall costs. Sto offers two primers, StoPrime® Hot and StoPrime®; both are available in sanded and smooth textures.

Sto Sealers

Acrylic-based exterior/interior topcoat ​​Sto Sealers enhance the color and fade resistance of Sto finishes and coatings, and add protection to the facade surface. Water-based, environmentally friendly Sto sealers come with slight gloss and matte finishes.
