Calcination
Deterioration of the surface of a paint outdoors by the action of weather, resulting in a faded surface covered with a whitish powder. Calcination occurs when the binder is degraded by harsh environmental conditions. It must be removed before repainting.

Coat
A layer of paint that is applied to a surface.
Density
Mass per unit volume.
Diluent
Liquid added to a paint to reduce its viscosity. A diluent is not necessarily a solvent for the binder.

E
Efflorescence
Migration of salts from the inside of a substrate to the surface.
Elasticity
Ability of the ink to expand and contract with the substrate, without suffering damage or changes in its appearance. Expansion and contraction are usually caused by variations in temperature and humidity.
Blistering
Bubbles form on the paint film.
Emulsion
A mixture (usually milky) in which one liquid is dispersed (but not dissolved) in another. The binder in a paint is called an emulsion.
Glaze
Varnish colored by metal oxides, usually used on wood and metals. It has a smooth finish, with a normally shiny appearance.
Spectrophotometer
It is a device that reads and decodes the color of a sample.
Thickener
Additive used to give the paint the appropriate viscosity.
Stability
The product’s ability to remain uniform in its appearance and performance.
Stucco
Mortar made with plaster.
F
Ferrous
It is said to be the metal that contains iron and is subject to corrosion.
Rust
Iron oxide, which appears in ferrous substrates and destroys them.
Paint Film
Film formed after the paint has dried.
Fungicide
Chemical added to paints and sealants, which prevents the growth of fungi on the painted surface.
Fungus
A black or grayish organic formation that can appear on the surface of a paint or sealant, especially in damp areas.
G,H,I
Galvanized
A metal part that has received a layer of zinc or other metal, which has made it more resistant to corrosion.
Water repellent
Product that repels water and does not let it enter the substrate.
Humidity
Impregnation of water or aqueous vapours.
Waterproofing
Product that does not allow itself to be crossed by fluids, especially water. Mainly applied on terraces or facades when insulation against water penetration is desired.
Impregnation
Filling effect, soak.
Inert
It is said of the substance that it is not easily modified by chemical action.
J, L, M
Gasket
Gap or gap between two building materials that meet (e.g., two tiles).
Washability
The ability of a paint to resist cleaning with household chemicals.
Binder
In paints and sealants, it is the component that binds the pigment particles, forming a uniform, continuous film and favoring their adhesion to the substrate. The nature and quantity of the binder determine most of the performance properties of paints (strength, adhesion, color retention, and durability) and sealants (durability, adhesion, and flexibility at low temperatures).
Sandpaper
They are mainly used on wood to remove imperfections, making it smoother. There are different categories in terms of use: sandpaper for wood, sandpaper for iron and sandpaper (used with water and other liquid solvents, which wash the impurities removed by the sandpaper).
Mate
Paintwork look without shine.
Half Gloss
Paint appearance between glossy and matte.
Membrane
Paint with the characteristic of being elastic (flexible) and waterproofing, usually applied to exterior substrates and repaintings.
N, O, P
Opacity
It describes the degree to which a particular material has to cover a background. An ink with high opacity completely covers the substrate.
Oxidation
Chemical reaction to oxygen. For example, the rusting of iron or steel.
Permeable
Which allows water vapor to pass through without damage.
Pigments
Solid particles, used to provide color, coverage, resistance to corrosion and filling power in the formulation of paints and complements.
Brush
An object consisting of a set of hairs or fibers, fixed to the end of a cable and used to apply paints, varnish, glue, etc.
Porous
Substrate that has pores.
Primary
Denomination used to define the product applied before the finishing paint, which aims to standardize absorption and provide protection against various types of agents.
Spraying

Remover
Prepared, usually liquid, to remove stains from the floor, clothes, etc., or to remove varnish, enamel, paint from a surface.
Yield
Measure that expresses the amount of paint used in a given area, usually expressed in m²/liter. The actual yield varies with the application method, substrate porosity, etc., and the nature of the paint.
Water repellents

Resin
Natural or synthetic material used as a binder in a paint or sealant.
Retouching
Application of a small layer of paint with the intention of mending a defect.
Saltpeter
The appearance of saltpeter efflorescence on the walls is caused by the crystallization on the surface of soluble salts that are transported by rising moisture or building moisture when it moves outside the walls. This problem often causes complete degradation of the media.
Solvent
It is used in paints to reduce viscosity or consistency in order to obtain greater ease of application. Among the most common solvents are water, turpentine, alcohol, acetone, thinner, and others. It is a liquid, usually volatile, in which ink particles are dissolved or dispersed.
