The paints may be applied by brush or spray; the small spray attachment for vacuum cleaners is very convenient, especially for painting radiators.
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.
Special Surfaces. WHITEWASH. Whitewashes and lime paints must be thin when applied. In fact, best results will be obtained if the application is so thin that the surface to which it is applied may easily be seen through the film while it is wet. The coating will dry opaque, but two thin Coats will give better results than one thick coat.
And, its never been more important to know your colors. Why? Because color is back in a big way! Just look at the vast variety of colors in the department stores.
Green is one of the main colors. It is physiologically optimal since this is the color of the natural environment, under the conditions of which people's color vision was created. Green color corresponds to stability, strength, constancy, perseverance, willpower, and the feeling of self-significance. Green color symbolizes prosperity and new beginnings, it calms you down and counterbalances. This color neutralizes the effects of the main colors and helps disperse negative emotions. It brings tranquility and peace, helps concentrate and increasing your likely hood in making decisions.
For localities where such conditions exist, self-cleaning paints should be selected. These paints are usually so designated on the label. Concrete, plaster, and metal surfaces each present special problems in painting. For instance, paint for use on masonry or new plaster must be resistant to dampness and alkalies, and paints used on steel must have rust-inhibitive properties.
The correct roller to use depends on the texture of the wall. On smooth walls you will need a 1/2" nap and on textured surfaces it will be more like a 3/4" - 1" nap depending on how rough the texture is. I always recommend a lamb skin, it will lay the paint off the best and provide maximum coverage. A roller pole is also great for saving your back, shoulder and arms from repetitious bending over and extension. If you will be using the roller for a couple of days, the same rule applies as with the brush, seal it in plastic completely to preserve it for the next day. Do not leave the roller submersed in paint or water over night, this will cause premature failure, by releasing the skin from the hardboard backing it is attached to. If you will be rolling a rough texture, like a stucco, make sure to purchase a roller frame (arm) that is sturdy and will hold up to constant applied pressure.
