      industrial maintenance coating means an architectural coating for application to substrates exposed to any of the following conditions:

      • (a) immersion in water, wastewater or chemical solutions or chronic exposure of interior surfaces to moisture condensation;

      • (b) acute or chronic exposure to corrosive, caustic or acidic agents or to chemicals, chemical fumes or chemical mixtures or solutions;

      sanding sealer

      sanding sealer means a clear or semi-transparent architectural coating for application to bare wood to seal the wood and to provide a coat that can be sanded to create a smooth surface for architectural coatings subsequently applied. (enduit à poncer)


      sealer means an architectural coating to be applied to a substrate to prevent architectural coatings subsequently applied from being absorbed by the substrate or to prevent them from being harmed by materials in the substrate. (produit de scellement)


      shellac means an architectural coating formulated solely with the resinous secretions of the lac beetle (Laccifer lacca), diluted with alcohol and formulated to dry by evaporation without a chemical reaction. (gomme-laque)

      varnish means a clear or semi-transparent architectural coating, excluding lacquers, formulated to dry by chemical reaction. Varnishes may contain small amounts of pigment to colour a surface or to control the final sheen or gloss of the finish. (vernis)

    • Marginal note:Overview

      (2) The table to this subsection sets out architectural coatings and their applicable VOC concentration limit. The table is divided into three columns. The first sets out the architectural coating subject to the VOC concentration limit, the second sets out the VOC concentration limit applicable to that architectural coating and the third sets out the anniversary of the day on which these Regulations come into force, from which the effective dates of the prohibitions set out in sections 3 and 5 of these Regulations are determined.
