Groove Textured Ceilings
It's almost impossible to paint right next to rough-textured ceilings (a process called 'cutting in') without getting paint on the ceiling. Taping off the ceiling doesn't work either. The solution? Knock off the texture at the edge with a putty knife. Hold the knife at a 45-degree angle to the wall and run the blade along the edge of the ceiling. The blade scrapes away the texture and leaves a small groove in the ceiling. Clean out the groove with a duster or a dry paintbrush.
Now when you cut in along the top of the wall, the paintbrush bristles will slide into the groove, giving you a crisp paint line without getting paint on the ceiling. And you'll never notice the thin line of missing texture.
Cut in Quickly with a Steady Hand
Cutting in along trim that's not protected by masking tape takes a steady hand. And once you get the knack for it, you'll never want to fuss with taping trim again. Sure, cutting in can be hard for some DIYers, but you can learn to do it effectively.
Use a tapered paintbrush. The angled bristles uniformly unload the paint as you cut in. Dip the brush into the paint, then tap (don't wipe) each side against your container to knock off the excess. Brush the paint on the wall, about 1/2 in. from the trim. Then make a second pass, cutting in all the way to the trim. Avoid 'pushing' the paint with your bristles or you'll leave a ridge where you're cutting in. Apply just enough pressure to let the bristle ends glide next to the trim. To help keep the brush steady, move your entire arm as you paint instead of moving your arm only from the elbow down.
Cover Paint to Keep it Fresh
Paint dries fast, even paint in your roller tray. If you need to take a break for more than 10 minutes, cover the paint. Place a lid on your 5-gallon bucket of paint and a damp cloth over your handheld paint container. Use aluminum foil to cover your roller tray. If you don't, the film that forms on top of the paint may end up on your walls. Here's a trick for storing paint brushes overnight.
