This is an oval shaped brush, which is great for all kinds of projects (big and small). The Staalmeester #40 has a blend of natural and synthetic bristles, which allows for it to hold a lot of paint, making your projects get done faster. Once done painting, rinse with water and the Fusion Brush Soap for a long lasting brush. Do not let paint dry on the brush. If you don't have time to clean it, let it soak in some water and clean later. If you are using your brush for numerous coats on the same day, you can wrap your brush in saran wrap in between coats.
