After so much work to gather supplies and prep walls, actually applying paint to your home's exterior will be an exciting metamorphosis. But first you need the right paintbrush.
There are two main types: natural bristle and synthetic bristle. Natural bristle brushes often are made of animal hair, including black or white hog hair, and have a soft texture for fine finishes. Natural bristles can hold a lot of oil-based paint without absorbing it.
While a natural bristle brush is good for applying a coat of primer or an oil-based paint, it isn't the best choice if your paint is latex (water-based) because it will absorb up to 40 percent of its own weight in water, making the brush too soft to paint properly [source: Wooster Brush].
For latex paint, you'll want to use a synthetic brush, made of nylon and polyester. These bristles don't wear out easily or absorb water from the paint. Look for a 4-inch (10-centimeter) straight-bristled brush and a 1.5-inch (4 centimeter) angled brush. The former will be used to cover large areas, while the latter will work well in small spaces, such as corners and near the trim [source: The Family Handyman].
