Acrylic:

A type of synthetic polymer used as the binder for high-performance water-based paints and sealants. Some acrylic polymers are used in auto finishes, appliance coatings, etc.

Adhesion:

The ability of a dry paint film or sealant to remain attached to the surface. Adhesion is probably the single most important property of a paint or sealant.

Aerosol:

Container dispensing a fine spray of pressurised liquid paint etc.

Algae:

Large group of unicellular non-flowering plants containing chlorophyll but lacking true stems, roots, leaves and vascular tissue. (eg Seaweed)

Alkali:

An alkaline, or “basic,” chemical substance such as lime or caustic. Generally present in fresh cement, concrete, plaster or certain household cleaning products.

Alkali burn:

A condition that occurs when the alkalinity in fresh masonry causes the breakdown of a paint’s binder, resulting in colour loss and overall deterioration of the paint film. Most likely to occur with vinyl acetate copolymer water-based and solvent-based paints applied to masonry surfaces that are less than a year old.

Alkyd:

A synthetic resin used in solvent-based paints. An alkyd resin is made by reacting a drying oil with a hard, synthetic material.

Anti-corrosive paint:

A paint designed to minimise rust or corrosion when applied directly to metal.

Anti-fouling paint:

Specially formulated paint for surfaces such as boat hulls and piers. It discourages attachment and growth of marine plants and animals.

Applied hiding:

Refers not only to the opacity of the paint film, but also to how it hides, depending on its thickness and how smoothly it flows out. Must take into account how the paint is applied (brush, roller, spray, etc.).
