Transform your popcorn ceiling with this comprehensive guide. Gather paint, popcorn texture, primer, rollers, brushes, and sprayers. Protect the room with drop cloths, ladders, goggles, and respirators. Apply primer, then paint using the roll-on, spray-on, or brush-on method. To create popcorn texture, use a sprayer and extension pole. Allow the paint and texture to dry, inspect for imperfections, and touch up as needed. Wear safety gear, ventilate the area, and clean up thoroughly.
