How can you identify a high-quality paintbrush? Pay attention to the bristles. They should:
• have split ends, to create a finer, more even finish; • have a definite flex at their tips, to enable them to spring back into shape; • be shorter on the outside and longer in the center, to provide more control over where the paint is applied; • measure at least half as long as the width of the brush. (For example, the bristles on a 2″ wide (50mm) brush should be 3″ (75mm) or more in length).
In addition, tug on the bristles before you purchase a brush. If more than one or two bristles can be pulled out, the brush is probably poorly constructed. Finally, make sure the brush feels comfortable in your hand. If a brush is well made and well cared for, it will last for years, so make sure you can use it comfortably.
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.
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. When applying alkyd or oil-based paints, you can use either synthetic or natural fiber covers.
