TJ’s Tip:
Good prep sets the job up right. Make sure surfaces are clean, dry and free from loose or flaking material before you start. For best durability and a uniform finish, apply two full coats — especially on bare or newly rendered surfaces. Taking the extra time at the start will pay off with a finish that lasts for years.
