The term paint is used to include paints, varnishes, enamels, shellacs, lacquers, and stains. • Paints are composed of mineral pigments, organic vehicles, and a variety of thinners all combined. • Varnishes are resins dissolved in organic thinners. • Enamels are pigmented varnishes. • Shellac is lac gum dissolved in alcohol. • Lacquers may be both pigmented or clear - the liquid portion usually is treated nitrocellulose dissolve in thinners. • Stains may be pigmented oil or a penetrating type. Many of these materials, such as paints, varnishes, and lacquers, are formulated for specific purposes: • Outside house paints and exterior varnishes are intended to give good service when exposed to weathering • Interior wall paints are formulated to give excellent coverage and good wash-ability. • Floor enamels are made to withstand abrasion. • Lacquers are formulated for rapid drying. • There are also formulas which provide extra self-cleaning, fume- resisting, waterproofing, hardening, flexibility, mildew-resisting, resistance to fading, and breathing qualities. Red color belongs to the three main colors (together with blue and yellow). This color has a lot of shades from light pink to reddish brown. Red is an ideal irritant, there is a reason it is used in corrida to irritate the fighting bulls. Airless Tip: If you have somebody who can start masking off the trim, have them start on that while you convert the airless to a new color. When changing colors with an airless paint sprayer it is a good idea to have a second bucket filled half way with clean water. Place the intake hose in the clean water gently without getting the old color everywhere in the water. Take the tip out of the airless and spray all of the old paint out of the hose and back into its original paint bucket. Be careful when doing this that you recognize when the paint starts turning watery. When it does point the gun into the first bucket and spray until it looks pretty clean. It doesn't need to be perfectly clean. When it looks good, clean off the intake line in the clean bucket and get the old color off the intake line. Now place the intake line inside of your new trim paint.
Paint Selection. Most paints are purchased ready-mixed but, in their selection, consideration should be given to the fact that surfaces vary in their adaptability to paint and atmospheric or other conditions having an adverse effect on paint performance. In addition to the normal weathering action of sun and rain, outside house paints are sometimes exposed to other attacking elements, such as corrosive fumes from factories or excessive amounts of wind-driven dust. Practically every manufacturer has a "color system," a fat book of color chips with instructions for duplicating each chip. This is accomplished by intermixing cans of colored paint, by adding a concentrated color to a can of white or colored paint, or by adding concentrated color or colors to a can of neutral "base" paint. And for those who don't want any guesswork there's the Color Carousel that mixes the paints right in the store. Whatever the method, the result is a range of colors such as no amateur painter has seen. COMPLIMENTARY COLORS. These are colors that are opposite from one another on the color wheel. Red and green, blue and orange, yellow and violet, are examples of complimentary colors. Complimentary colors are colors of extreme contrast. When used together in a painting, they can produce brilliant vibrant images. Interior paints are used to obtain pleasing decorative effects, improve sanitary conditions, and insure better lighting. These paints may be divided into four types: wall primers; one-coat flats; flat, semigloss, and gloss; and water paints.
