A. Definitions. In
				  this regulation the following terms have the meanings indicated.
B. Terms Defined.
(1) "Basecoat" means a coat of colored
				  material, usually opaque, that is applied before graining inks, glazing coats,
				  or other opaque finishing materials, and is usually top-coated for
				  protection.
(2) Clear Topcoat.
(a) "Clear topcoat" means the final coating
				  which contains binders but not opaque pigments and which is specifically
				  formulated to form a transparent solid protective film on wood
				  substrates.
(b) "Clear topcoat"
				  includes clear brushing lacquers, clear lacquers, sanding sealers, and
				  varnishes.
(3)
				  "Conversion varnish" means a clear acid curing coating with an alkyd or other
				  resin blended with amino resins, which:
(a) Is
				  supplied as a single component or two-component product designed for
				  professional application to wood flooring to produce a hard, durable, clear
				  finish; and
(b) Results in a film
				  formation from an acid-catalyzed condensation reaction, affecting a
				  trans-etherification at the reactive ethers of the amino resins.
(4) "Daily weighted average" means
				  the volume-weighted VOC content, expressed in grams VOC per liter (or pounds
				  VOC per gallon) of all coatings, less water and exempt compounds, as applied on
				  a given day.
(5) "Exempt compound"
				  means a compound identified as exempt under the definition of volatile organic
				  compound (VOC) under COMAR
				  26.11.01.01 a B.
(6) "Filler" means a preparation used to fill
				  in cracks, grains, and imperfections of wood before applying a
				  coating.
(7) "Paint remover or
				  stripper" means a product designed to strip or remove paints or other related
				  coatings, by chemical action, from a substrate without markedly affecting the
				  substrate.
(8) Pigmented Coating.
(a) "Pigmented coating" means opaque coatings
				  that contain binders and colored pigments.
(b) "Pigmented coating" includes opaque
				  coatings that are formulated to conceal the wood surface either as an undercoat
				  or a topcoat.
(9)
				  "Primer" means a coating labeled and formulated for application to a substrate
				  to provide a firm bind between the substrate and subsequent coats.
(10) "Sealer" means coatings containing
				  binders that seal a wood surface prior to application of subsequent
				  coatings.
(11) "Stain" means a
				  clear, semi-transparent, or opaque coating labeled and formulated to change the
				  color of a surface, but not conceal the grain pattern or texture.
(12) "Topcoat" means the last film-building
				  finishing material that is applied in a finishing system.
(13) "Washcoat" means a coating containing
				  not more than 1 pound of solids per gallon designed to seal wood surfaces,
				  prevent undesired staining, and control penetration.
(14) Wood Coating Operation.
(a) "Wood coating operation" means an
				  operation used to coat any product made of wood, a wood product such as rattan
				  or wicker, or an engineered wood product such as particleboard.
(b) "Wood coating operation" does not include
				  residential noncommercial operations and flat wood paneling coating subject to
				  Regulation .33 of this chapter.
