Is it ready? A coat of latex or quick-dry primer will generally be repaintable in about four hours. Ask your salesperson about the particular product that you buy.

The great cover-up: Flat finish paint hides imperfections better than semi-gloss or gloss paint, which is why it's generally used for walls.

2torial #0494: Learn2 Paint a Room (Continued) Paint the first coat--corners Whether you use a primer as your first coat (highly recommended) or not, the mechanics are the same. When painting, you want to work from the ceiling to the floor down, so splattering doesn't mar your finish. This means painting the ceiling first, then the walls and finally the trim.   Fill up a bucket. There's no need to carry around a heavy gallon-can of paint, unless you're very keen on the idea of it. Instead, fill up a plastic quart-container and dip your brush into that.   Dip and tap. Rather than soaking the brush up to your knuckles in paint, and wiping it on the side of the can, try this alternative. Dip about a third of the brush length into the paint. Then, with a snap of the wrist, tap the side of the brush on the side of the can, two times. This removes just enough paint so that the brush won't drip.     Paint the corners in three locations: where the ceiling meets the wall, where the walls meet each other, and where any trim meets the wall. You're doing this so that the roller doesn't have to make it all the way to the edges. When applying the paint, put the wet brush down just ahead of a freshly painted area, and brush back into it to blend nicely. Avoid leaving globs of paint. For both the ceiling and the wall surfaces, paint out from the corner about two inches. Use the width of your brush as a guide   Use a stepladder. To reach some of those corners, it's best to use a stepladder. If none is available, tape the small brush tightly to the four-foot roller extension. With this rig, you may need to retape the brush a few times to make it around the room. Step 5
