Paint like a pro with these expert tips! TIP #1) Start painting at the top, and work your way down. TIP #2) Tape off areas you need to protect, such as the porch floor when you’re painting the walls. TIP #3) Use two to three coats for nice, even coverage. TIP #4) Sand the surface and all edges before applying the second and third coats—this will give you a smooth, blemish-free finish.
