Spray Paint Guns If you're painting a large area, using an HVLP paint spray gun for even layers requires less effort. However, spray guns can be expensive. So, for smaller surfaces like garden furniture, a paintbrush is a more suitable choice. Paint Brushes Paint brushes are common and inexpensive, and available in various sizes for different applications. They allow for detailed and intricate designs, as well as the application of thin coats. Rollers When using rollers, choose one that matches the size of the surface you're painting. Rollers provide efficient and consistent application but lack the precision of a paintbrush.
