Selecting the Right Paint Tools

Selecting Paint Rollers Rollers are faster and easier to use than paintbrushes, especially when painting walls, ceilings, and other large, flat areas. They are also excellent for use on tough exterior surfaces like stucco and concrete. Caption: (rollers, right): Rollers come in various widths and nap lengths. Selecting the proper nap length for the surface to be covered will ensure an even finish. Rollers come in various widths and nap lengths. Selecting the proper nap length for the surface to be covered will ensure an even finish. However, rollers are difficult to work with in small or narrow spaces, so you'll probably need to buy several different sizes of rollers, and one or more paintbrushes. As with brushes, when you are applying latex paints, make sure you use roller covers made with a synthetic "nap," or fiber surface. Whets applying alkyd or oil-based paints, you can use either synthetic or natural fiber covers. An important consideration when selecting a roller cover is the length of the nap. In general, you should paint smooth surfaces with short-nap rollers, and rough surfaces with long-nap rollers. When applying gloss or semi-gloss paints, short nap covers tend to generate less foam during paint application. Recommended nap lengths for some common surfaces are as follows: • wallboard, smooth plaster, wood, or metal - a short nap of 1/8" to 1/4" or 5mm • light-textured stucco, poured concrete, and rough wood - a medium nap of 3/8" to 3/4" (l5mm to 20mm) • heavy-textured stucco, concrete block, and brick - a long nap of 3/4" to 1" (25mm to 30mm) As with brushes, it is wise to purchase better-quality roller covers, even though they may cost a more initially. High-quality roller covers apply paint more easily and are less likely to leave nap fibers on the painted surface. While price is a good indicator of quality, you can also test the quality of a roller cover by squeezing it. A high-quality cover will quickly return to its original shape. Also be sure the roller cover has no obvious seams, since these tend to leave streaks when you apply the paint. Standard roller widths are 7 1/2" and 9" (190mm and 240mm). The 9" (240mm) size is suitable for most interior wall and ceiling jobs. Mini-rollers, about 3" (75mm) wide, are convenient for painting trim and narrow areas. Paint Pads Paint pads can help you apply paint in hard-to-reach places, including those where neither brushes nor rollers will fit. While they are not recommended for applying paint to entire walls, since lap marks may result, paint pads are especially helpful when cutting in corners and painting areas where walls and ceilings meet. Most paint pads are made of foam or mohair, and can he used to apply both latex and oil-based or alkyd paints. In most cases, the pads can be replaced when worn or damaged. Paint Sprayers For quick coverage of large surface areas, it is tough to beat power-spraying equipment. While sprayers may use more paint than other types of applicators, the ease and convenience they offer make them ideal for large jobs. Conventional sprayers use compressed air as the pressurizing agent to deliver the paint. Airless sprayers, pump the paint directly. Achieving proper coverage with conventional sprayers can be tricky business, but accomplished do-it-yourselfers can get good results with airless sprayers. Hand-carry electric airless sprayers are a good choice for interior painting; larger, wheel-around gasoline or electric units are better suited for extensive exterior work. As with all power equipment, be sure to follow the manufacturer's instructions for setup and operation. Most important, never point an airless sprayer at any person or pet because the pressure of the spray is strong enough to inject paint into the bloodstream, which can be harmful or even fatal. Finally, when doing exterior painting, avoid working on windy days.
