|
| Earth tones |
| The natural colors of earth; browns and beiges. |
|
| Edging |
| Act of striping in or painting near the edge of a surface, such as the wall intersection at ceiling, doorway, or window. |
|
| Effervescence |
| An effect in the film caused by rapid solvent release. This "boiling" of solvent causes a pinholed or cratered appearance reducing gloss. |
|
| Efflorescence |
| Water soluble salts, deposited as moisture evaporates, on the exterior of brick or concrete. These are usually sodium salts that diffuse through the paint film from the substrate. |
|
| Eggshell |
| A thin, brittle semi-matte paint finish. |
|
| Elcometer |
| A trademark and brand name for a magnetic instrument for measuring dry film thickness of coatings applied to steel surfaces. |
|
| Electrostatic Spray |
| The spray application of paint where the particles are charged causing them to be electrically attracted to the grounded surface. |
|
| Embossed paper |
| Wallpaper with a raised, textured pattern. Embossed wallpapers are useful when installing over imperfect wall conditions, as they will camouflage contours on an uneven wall. Do not use a seam roller on embossed papers because it can flatten or burnish the raised effect and cause a shiny streak to appear. |
|
| Embrittlement |
| Severe loss of ductility of a metal or alloy. |
|
| Emulsifier |
| A material which when added to a mixture of dissimilar materials, such as oil and water, will produce a stable, homogenous emulsion. |
|
| Emulsion |
| A two phase liquid system in which small droplets of one liquid are immiscible in and are dispersed uniformly throughout a second liquid. |
|
| Enamel |
| Paint with finely ground pigments and a high binder content so that it dries to a hard gloss or semi-gloss finish. |
|
| Ending point |
| The point where the wallpaper stops at an obstacle. Examples include fireplaces, accent walls and kitchen cabinets. |
|
| Epoxy |
| A two-part compound used to fill holes in damaged wood. Once dry, epoxy patches are very strong and can be sanded, primed and painted. |
|
| Epoxy adhesive |
| Adhesive based on an epoxy (or epoxide) resin or several such resins. They are of limited use in furniture-making but come in handy for quick repairs. |
|
| Epoxy Resin |
| A synthetic resin produced by the reaction of epichlorohydrin and bisphenol. Epoxy resins may be used alone (unmodified) or modified with drying oils (epoxy esters) for coating vehicles. |
|
| Erosion |
| Deterioration of a surface by the abrasive action of moving materials - fluids or particles. This is accelerated by the presence of solid particles or gas bubbles in suspension. |
|
| Ester |
| Compounds formed by the reaction of alcohols and organic acids. |
|
| Etching |
| Scratching or roughening an existing wallpaper surface to prepare it for the application of a wallpaper-removing solution. The etching of the vinyl-coated surface allows the solution to penetrate through the wallpaper and dissolve the old adhesive to aid in the removal of the existing wallpaper. |
|
| Evaporation Loss Solvents |
| A solvent whose volatility is high. Used to reduce the flash-off time of a paint to combat sagging on cool days. |
|
| Evaporation Rate |
| The speed with which a solvent volatizes or evaporates. It is frequently expressed as the time required for 1 cc. of solvent to evaporate after being poured onto filter paper. |
|
| Exposure |
| The intensity, duration and variation in sun, wind and temperature that characterize any particular site. |
|
| Extender Pigments |
| Pigments used to provide texture, bulk or hardness to a coating. Also known as inert pigments. Magnesium silicate and diatomaceous silica are examples of extender pigments. |
|
| Extenders |
| Inert pigments used to extend or increase the bulk of a paint. Extenders are also used to adjust the consistency of a paint and to let down colored pigments of great tinting strength.. Extenders sometimes improve certain characteristics of a film. |
|
| External Mix/Atomization |
| Using air to break up a coating material after it has exited the spray gun nozzle. |
