What’s the best type of flat brush for walls

When shopping for a flat brush specifically to use for your walls, there’s a couple things you should keep in mind. The first thing to note is the size of the brushes available. Larger sizes - usually found in 3-inch, 4-inch, and 6-inch sizes - will be more beneficial if you’re planning to paint larger sections of your wall. If you want to do more intricate work like touch-ups, look for a brush or brush set with a smaller size.

The other thing to keep in mind is the material. Brushes with soft to medium stiffness tend to offer the best results when trying to create a smooth finish. Nylon-polyester is the most popular option and is a great choice when working with walls.

Best way to paint walls with a flat brush

Once you have your brush(es), it’s important to know how to use them in order to give your walls the best results. Here’s some tips to help you learn the best ways to paint your walls using a flat brush.

  • Use smaller amounts of paint - Dip your bristles ⅓ of the way into the paint and tap the brush on the side of the can to remove excess. This will prevent you from applying too much paint at once and making unnecessary messes.
  • Hold the brush on an angle - Holding your brush at 45 degrees is recommended. This will help you maintain control as you paint.
  • Distribute your paint - Once you’ve initially applied your paint, you’ll want to start pushing it horizontally across the surface. This will help create a smoother finish.
  • Try feathering - At the end of each stroke, lift the brush from the wall. This will help prevent any marks or lines being left behind.
