| Abrade
- To scrape or rub off a surface layer. |
|
Binder
- The part of a paint that h olds the pigment particles together, forms a film, and
imparts certain properties to the paint. It is part of the solids and is also known as
vehicle solids.
Bleed -
Color penetrates up through another coat of paint.
|
|
Calcium carbonate - An exterior pigment.
Coalescence
- The merging into a single mass.
Crown molding
- The uppermost moulding next to the ceiling.
|
| DFT
- Dry film thickness. The mil thickness when coating has dried. |
| Efflorescence
- A white alkaline powder deposited on the surface of stone, brick, plaster, or mortar
causing leaching. |
|
Faux
- French for fake or false. These include marbling or other imitation finishes.
Flagged bristles
-Split ends.
Flatting -
Lowering of the gloss.
Flexibility
- Ability of paint film to withstand dimensional changes.
|
|
Gel
Coat - A thin, outer layer or resin, sometimes containing pigment, applied
to a reinforced plastic moulding to improve its appearance.
Gloss -
Luster. The ability of a surface to reflect light. Measured by determining the percentage
of light reflected from a surface at certain angles.
Gum - A
solid resinous material that can be dissolved and that will form a film when the solution
is spread on a surface and the solvent is allowed to evaporate. Usually a yellow, amber,
or clear solid.
Gypsum Board
- Thin slabs of plaster covered with a heavyweight 100 percent recycled paper covering.
|
|
Hiding
power - The ability of paint film to obscure the substrate to which it is
applied. Measured by determining the minimum thickness at which film will completely
obscure a black and white pattern.
Humidity -
The amount of water vapor in the atmosphere.
|
| Kiln
dried - Controlled drying in an oven to a specific moisture content. |
| Luster
- Same as gloss. |
|
Mill
scale - An almost invisible surface scale of oxide formed when iron is
heated.
Mils -
Measurement of thickness of film. One-thousandth of an inch. One mil equals 25.4 microns
(micrometers).
|
| Non-bridging
- A paint that will not cover the small holes in an acoustical tiled ceiling. |
| Oxidation
- Chemical combination of oxygen and the vehicle of a paint that leads to drying. |
|
Reduction
- Lowering the viscosity of a paint by the addition of solvent or thinner.
Resin - A
solid or semisolid material that deposits a film and is the actual film-forming ingredient
in paint. May be natural or synthetic. See Gum.
|
|
Solvent
- A liquid that will dissolve something, commonly resins or gums, or other binder
constituents and evaporates in drying. Commonly an organic liquid.
Strike-off
- A small sample run off for color or pattern.
Substrate
- The piece or object that is to be painted.
|
|
Titanium dioxide - A white pigment providing the
greatest hiding power of all white pigments. Non-toxic and nonreactive.
Tooth -
The slight texture of a surface that provides good adhesion for subsequent coats of paint.
|
|
Vehicle
- All of paint except the pigment; the liquid portion of a paint.
Viscosity
- The resistance to flow in a liquid. The fluidity of a liquid, i.e., water, has a low
viscosity and molasses a very high viscosity. |
