If you have masked the trim with tape, use the tape as a guide.

Even the best painter’s tapes may allow some paint to sneak around the edge and onto your trim.

Avoid relying on the tape for complete protection.

Instead, use the brush to paint up to the tape.

Try not to paint the tape itself.

Prepare Roller With Paint

Dip the rollerinto your paint bucket.

Don’t immerse it for too long; overloaded rollers cause major drips that are tough to roll out.

Pull the roller back up the screen several times until the roller is coated all around.

Keep rolling up and down until you hear a sticky sound.

Do this several times until you are confident that the roller cover is coated in paint.

Work quickly enough so the paint edges you are rolling over are still wet.

Flat and matte interior paints are forgiving when it comes to painting over drier edges.

Fill in and Complete

Continue rolling out blocks of paint using the W method.

Occasionally step back to view your work.

Work in a strong light to catch any missing spots.

While painting, stay as far away as possible from areas you don’t want to be painted.

Even better, cover them with tarps or drop cloths.

Rollers can accidentally splatter and spray paint off the roller and onto the surface.

If the walls are in bad shape, a professional painter may wash the walls for better results.

If the walls are in decent shape, they may not take the time to do a thorough cleaning.

If you’rehiring pros, ask what jot down of cleaning is included in the contract.
