MATERIALS OF DESIGN AND DECORATION (PAINT)

Acrylic

A general class of resinous polymers derived from esters, amides or other acrylic acid.

Alkali Resistant

Paint used on new plaster, which is durable in contact with lime.

Anchoring

Mechanical bonding of a coating to a rough surface as contrasted with adhesion, which is chemical bonding.

Anti-Corrosive Paint

Metal paint designed to inhibit corrosion

Anti-Fungus Paints

Paints contain toxic compounds, which kill any fungi attempting to feed from it.

Anti-Slip Paint

Paint that contains a grit (sand, plastic chips, cork dust) that forms a grippable surface that breaks the "tension" of the water.

Antiquing

This is the process of artificially ageing paint

Bambooing

The imitation of bamboo through painting turned or carved wood to copy the bamboo knots and grains, the decorating it.

Bleeding

Undercoat staining through the topcoat.

Blistering

Bubbles or blisters in the paint film.

Blushing

Milky opalescence on lacquer usually happens if paint was applied in wet or cold weather.

Chalking

Powdery deposit being formed on a dry paint film surface.

Checking, Cracking, Crocodiling, Alligatoring

Splits that appear in the film of the surface coating. Caused by the use of excessive driers or recoating before the undercoat is dry.

Colorwash

Diluted layer of paint or propriety product that is applied over the base coat to provide a wash or "glimpse" of color.

Crackle-Glaze Paint

This imitates old peeling paint and provides a cobweb look

Craquelure

This is a process that was developed to imitate the crazing of very old varnish.

Deviling

Scratching plaster to prepare the surface for the next coat.

Distemper

A type of paint made by mixing the pigment with glue or size.

Distressing

This is making a finish look older that it really is or time worn and rugged

Drier

A chemical preparation added to paint which causes it to dry quickly.

Efflorescence

A white fluffy surface deposit that is caused by salts in the plaster being drawn to the surface.

Eggshell Paint

This is actually now referred to as semigloss paint with a finish midsheen between matt and gloss.

Finishing Coat

These are finishing or final coats.

Flaking

Paint or varnish lifting away from the surface in the flakes because of the breakdown of the adhesion.

Fresco

Method of painting on wet plaster with tempera colors

Gilding

This is essentially the application of a gold finish

Glazing Compound

Puty used to set glass in window frames and to fill nail holes and cracks

Graining

Painting imitation of the fiber lines of wood.

Japanning

A type of varnishing, to imitate the lacquering work from the east.

Lacquer

A glossy type of paint finish

Lacquering (Jappaning)

This is the layering of numerous coats of varnish, sanding in between coats. This creates a smooth lustrous effect.

Negative Stencil

The paint is passed through the voids that surround the design.

Primer

This is the first coat of paint that is applied to a raw (unpainted) surface.

Rivelling

Wrinkles occurring in the paint film as it dries. This happens if the paint has been applied too thickly.

Thinners

Solvents used to thin coatings.
