Fast Tip: DIY Door Painting Hacks
When painting any type of door, always start with the edges. Remove the door handle and locks. Start by rolling the paint on the top half of the door. Dip the roller into the tray for more paint and continue to roll the bottom half of the door. To smooth the paint out, finish by rolling the full length of the door with light-pressure strokes.
Once dry, apply a second coat following the same process. For paneled doors use a paintbrush. Begin by painting the top of the door, panels first, then rails (horizontals) followed by the stiles (verticals).
