How to Paint Borders on Textured Walls

Wipe the wall area with a feather duster or soft cloth. This removes any cobwebs, dust or other debris.

Place strips of painter's tape where you want to add the border. It peels off easily without removing any of the existing paint color once you are done. Use a level or tape measure to ensure that the border area is even.

Pour a small amount of the wall paint into the paint tray. Some people use monochromatic colors that are close to the existing paint on the walls, and others choose bold, contrasting colors to make the borders seem to pop. If you want even more contrast, use a semi-gloss paint over a flat or matte finish to accentuate the border area.

Dip a regular paintbrush into the paint tray. Apply the paint to the border area with an "X" motion. This helps work the paint into the crevices on the textured wall.

Push the paintbrush bristles gently into the textured wall areas and wiggle the bristles. This helps the paint get down into the textured sections that the diagonal motions don't cover.

Step away from the wall after you finish. Check for any thin areas or spots you missed. If you locate any, apply additional paint until you're satisfied with the result.

Wait for the wall border to dry thoroughly before removing the painter's tape.
