It can be interesting to see Homeowners who are pressed to purchased the best quality paint yet compromise the job by trying to save a money on paint brushes. The right brush will save time and and money because it will carry more paint and enable the Painter to have better control. A better brush will also provide a smoother finish with less visible brush strokes. Not only that, you're far less likely to see those annoying brush hairs dried into the paint. One should expect to pay at least $15 for a decent 2 1/2-inch trim brush. If the brush is properly cleaned and cared for, it will last you for future projects.
Another common mistake that some people make is to use the wrong type of brush. The best brush for modern latex-based paints is one made with synthetic bristles that are usually comprised of polyester or nylon. China bristle brushes, should only be used with oil based paint. If China Bristle brushes are used with latex based paints the fibers will actually absorb water and cause the bristles to loose their correct shape.
Synthetic Bristle Brushes are made with nylon bristles that are soft or polyester material that is not soft. Softer bristles provide a smoother finish, while stiffer bristles can provide better control. The best trim brushes for general uses are typically made with nylon and poly blends and have good flexibility. If you're painting with a high quality product like Sherwin Williams Aura, it is best to choose a brush with an tighter flex. This will bring excellent control, even in hot or humid conditions. For thinner type of paint, such as, semi gloss or high gloss trim paints, many professionals like Davinci's Painters in Reston Virginia use ester fiber brushes that are specialized. These brushes leave an excellent finish without brush marks.
That being said, there are some things to consider when choosing a paint brush. A good indicator of quality is flagging, or the split ends that you can sometimes see at the ends of the bristles. Synthetic bristles need flagging to leave behind a smooth finish. The best idea is to avoid painting brushes that are susceptible to flagging. Compare bristle density. Paint is held in place by the space between the bristles, so the more bristles a brush has, the more paint it will hold. This is often the choice for Painting Professionals because there is less loading paint on the brush. Good brushes are also tapered. The bristles of less expensive brushes are all the same length. Tapering the bristles so that the brush is thicker toward the ferrule which is the metal ring that holds the bristles against the handle. This makes the brush more rigid and provides better control over the application.
Handle shape is a matter of personal preference. Many Painters in Northern VA prefer a beveled profile rather than one that is straight. The best advice for Homeowners is to find a brush that feels comfortable in your hand and that provides good control. 3" width brushes are good for cutting in ceilings and walls which are usually flat surfaces. However when painting trim surfaces like windows, it would be better to use a 2" angled paint brush. In fact, 2" angled sash brushes are probably the most popular brush because they're comfortable to use and can also be used for cutting.
There are a few simple tests that people can perform to check the quality of a paint brush. If some brisles pull out of the handle easily, that would be a good indication that it not a quality brush. You may not select the perfect brush at the start, and you certainly won't find one in any type of bargain priced packs, but it is wise to remember, that the brush tool that you will be working with is the most important factor that provides the look of your job. Buying the right tools will always render a superior finish.
