Painting a room is a common DIY project that many people undertake on their own. They pick up paint, a paint tray, a paintbrush, and a paint roller, then get started painting the walls. However, if you haven't tackled a paint project before, you may not know that paint, paint trays, paintbrushes, and paint rollers come in several different types. Choosing the wrong paint tray can slow down the project, while selecting the wrong brush can leave you with a streaky finish. For these reasons along with several others, it's important to learn more about the paint and tools you need before starting a project.
