Abrasion

Wear caused by attrition.

Finish

The final stage of the paint job, to which decorative and/or protective effects are attributable, such as the desired color, gloss level, texture, weathering resistance and other features.

Additive

A raw material that is added in small proportions to impart specific characteristics or properties of the paint, such as anti-settling effect, drying performance, plasticization, etc.

Spreading

The coating’s ability to spread evenly and form a homogeneous, uniform film.

Calcination

A whitish, dusty deposit formed on the surface of the coating film due to resin degradation.

Filler

A natural or synthetic inorganic material that imparts to paints such properties as filling, texture, gloss control, opacity and abrasion resistance, among others.

Hiding

A paint property that makes the substrate opaque when it is coated with it, provides opacity. Hiding can be seen on both the wet and dry coating films.

Colorant

A natural or synthetic soluble substance used to provide color.

Cracking

A flaw on the dry coating film in the form of cracks or fissures, which may or may not expose the substrate.

Coat

Each layer of paint applied on a substrate.

Diluent

A volatile liquid compatible with the paint whose purpose is to set viscosity levels or the paint supply or use consistency. It can also be used to clean the application equipment.

Efflorescence

A whitish mineral salt deposit originating in the substrate that appears on the surface of finishes.

Blistering

Blisters formed on the dry paint or varnish film originating from liquids or gases.

Enamel

A paint used as finish in both indoor and outdoor environments, usually to protect and decorate metal and wood surfaces. Examples include products commercially known as synthetic enamels, water-based enamels and oil-based paints.

Coverage

The application of a coating product on a surface, forming a continuous film, regardless of the hiding performance and thickness of the applied coat.

Film

A coat of paint applied on a substrate.

Basecoat

A primer, sealer or other product designed to prepare surfaces to receive a finish.

Wall preparation primer

A primer designed to promote the cohesion of loose particles on a surface.

Washability

The ability of a coating film to withstand washing.

Leveling compound

A complement designed to level, even out and fix minor flaws on masonry or wood surfaces (popularly known as spackling paste, acrylic filler or oil-based filler putty).

Leveling

A paint property of forming a uniform film without any application marks.

Coating film

See Film.

Pigment

A solid, insoluble substance, either organic or inorganic, that imparts color properties to the film. It can also provide other properties, such as hiding, chemical strength and corrosion resistance, among others.

Polymer

A high-molecular-weight substance produced by a chemical reaction known as polymerization, whose structure is formed by a repetition of structural units bound together by covalent bonds.

Primer

A basecoat recommended for promoting adhesion and/or fostering surface protection (see Basecoat).

Resin

A substance responsible for the formation of the coating film that provides such properties as waterproofing, chemical strength, weathering resistance, gloss, hardness, adhesion, flexibility, etc.

Abrasion resistance

The ability of a product to resist the mechanical wear caused by sanding or brushing, among other sources of wear.

Drier

A compound that either promotes or accelerates the drying process in paints and varnishes based on drying oils.

Sealer

A basecoat designed to seal and even out absorption on the surface (see Basecoat).

Solvent

A volatile fluid that enables the resin to dissolve and keep all components in a homogeneous mixture, providing the appropriate viscosity level for each application. Its evaporation rate and solvent power influence a proper coating film formation.

Stain

A finish product designed for wood that, upon application, is absorbed by the substrate and, upon final drying, forms a thin coating film, which may be either clear or opaque.

Substrate

Any or all surfaces onto which a coating system is applied.

Paint

A chemical formulation consisting of a pigment dispersion in a solution or emulsion containing one or more polymer types that, after applied on a surface, turns into a film that adheres to it in order to color, protect or beautify it.

Latex paint

A paint based on a waterborne polymer dispersion that may consist of acrylic, vinyl or other polymers.

Thinner

A diluent consisting of mixed solvents.

Textured coating

A coating product that delivers different effects through the use of appropriate techniques or tools during application.

Varnish

An organic coating that, when dry, forms a clear film used as finish in indoor and outdoor environment to protect and decorate wood, concrete and other surfaces.

Volatile

Every material that evaporates under normal temperature and pressure conditions.
