When it comes to getting great results in home improvement projects, Ron believes in using the best tools you can afford. This is as true for paint brushes as anything else.
It used to be that brushes fell into one of two categories: natural bristle for oil based paints and nylon for latex or water based paints. But nowadays the nylon polyester blend can cover everything.
A good quality brush should have plenty of densely packed bristles that are straight, evenly trimmed at the end and securely fastened into the ferrule to eliminate shedding.
The standard or square end brush is used for applying paint to a flat surface while the angle or sash or trim brush on the other hand is used for cutting in and can be used in either direction.
A brush will work better and last longer if it's thoroughly cleaned after every use. Start by rinsing the bristles under running water and then bend them back. This will dislodge any paint that may be trapped up close to the feral.
If you have a small job to do, and you don't want to bother cleaning your brushes, you might consider a disposable version. All you do is paint and pitch.
