Use flaps to protect trim from roller spatterExtending the masking tape with a piece of 3-in. masking paper is all that’s needed to protect the woodwork from most roller spatter and drips. Three-inch paper is ideal because it’ll stand straight out. Wider paper may seem like a better idea, but it’ll sag and won’t provide as much protection. And since the 3-in. paper doesn’t sag, you’ll still be able to close doors without the paper getting in the way.
Apply 3-in. paper along the top trim of windows and doors and along the baseboard. Don’t bother to fit the paper tight into corners along the baseboard; you don’t need much spatter protection there.
Stick 3-in. masking paper to the underside of the tape to shield trim from paint spatters and drips.
