How to Paint Vaulted Walls

Lay plastic sheeting near the base of the wall. Dripping is a major concern for high, vaulted walls.

Position a ladder at the base of the vaulted wall. A-frame ladders provide the most stability, but if you can only reach the wall with an extension ladder, make sure somebody holds the base of the ladder for stability as you work.

Protect trim with painter's tape. For vaulted trim sections, reposition the ladder as you apply the tape. Avoid leaning haphazardly over the edge of the ladder. If you can't reach a surface comfortably, it's time to move the ladder.

Put on protective eye wear. As you paint, you'll likely be staring directly at high, vaulted surfaces. If paint drips into your eye from these surfaces, you risk flinching and falling from the ladder.

Paint the vaulted wall trim using a foam paintbrush and latex paint. Foam brushes provide thinner coverage for less chance of dripping.

Roll latex paint onto the main vaulted wall surfaces using a foam roller and extension handle. With an extension handle, you won't have to climb as far up the ladder or strain your arms with excessive overhead movement.

Apply a second coat of paint to the edges and the main surface after the first coat dries.

Dispose of the plastic sheeting and remove the painter's tape after 24 hours.
