More than just a bushel of bristles, paint brushes are a key ingredient to a paint job well done (read: any old paint brush simply won’t do). You need a brush that will meet your project-specific needs, and choosing the right one narrows down to two factors: the project and the paint.
If you’re using oil-based paint, opt for a brush with natural bristles, which cling to oil-based paint better than synthetic fibers do.
For latex paint, a synthetic paint brush, like nylon or polyester, is the best option. Synthetic fibres won’t absorb water-based latex paint, whereas natural fibers do.
Paint brushes come in a variety of sizes:
- 1 – 2.5 inch brushes are best for painting small trims
- 3 inch brushes are great for painting medium-sized surfaces like doors or furniture
- 4 – 6 inch brushes should be used for painting large surfaces like walls or outdoor decks
Follow this universal rule: for painting flat surfaces, use a flat, square paint brush. For painting angled surfaces like corners or trims, use an angled brush. Whatever the shape, keep in mind that the best paint brushes have bristles in varying lengths opposed to a rigid edge.
The quality of your paint brush will affect the quality of your finished project. Cheap brushes that fray or shed easily will leave your project ridden with brush streaks and messy loose fibers. Quality brushes may cost a bit more but will provide a smooth, professional finish in the end.
