Grab a roll of painter’s tape-the cousins recommend FrogTape-and firmly apply it to the edges of the room’s corners, base and crown moldings, and door and window casings, using a putty knife to seal if needed. “Don’t skip the drop cloth-paint will splatter, we promise,” say New Jersey contractors-and cousins- John Colaneri and Anthony Carrino, the stars of the HGTV series Cousins Undercover and Kitchen Cousins as well as The Build Up and Grand Design on Ellen DeGeneres’s Ellentube.
