The walls in a mobile home aren't much different from the walls in a regular home. The walls may be made of different building materials, but the painting process remains the same. When the ceiling isn't to be painted, it must be protected from paint splatter. The floor beneath the wall must also be protected. Water-based paints can be used for mobile home wall applications to minimize paint odors and provide a beautiful paint finish.
Prepare the walls for painting by removing all decorations, electrical outlet plates, window blinds or curtains, light switch plates and hardware. Use flat or hex-head screwdrivers to remove these items.
Mask off window frames with 2-inch masking tape. Run the tape around the frame by pressing your fingers onto the tape to stick it in place. Get the tape as close as possible to the corner where the frame meets the sill.
Run a piece of tape along the edge where the floor meets the wall. Do this along any wall that will be painted. Keep the outer edge of the tape loose.
Lay painter's plastic down on the floors and tuck the plastic beneath the tape along the wall to hold it in place.
Fill any holes in the wall with fast-drying repair mud using a 3-inch putty knife. Caulk all seams, cracks and joints with caulking.
Sand the patched areas using a 120-grit sanding block.
Wipe the dust off the walls with a tack cloth.
Open a quart of stain-blocking primer paint.
Dip a paint brush into the primer paint and paint all of the stains and mud patches. Allow the primer paint to dry for an hour.
Clean the paint brush with water and then spin it to get the excess water out of its bristles.
Pour a little bit of finish paint into a hand-held paint holder.
Dip the paint brush into the paint until the bristles are loaded with paint.
Go to the left side of the first wall to be painted. Paint a straight line across the top of the wall where it meets the ceiling. Paint the corners of the wall. Paint the bottom of the wall. Paint away from the ceiling, the adjacent walls and the floor at least 3 inches so the roller won't get paint on them.
Pour the rest of the finish paint into a 5-gallon bucket. Stir the paint in the bucket until it is mixed evenly using a stir stick.
Place a roller 1/2-inch nap roller cover onto a roller frame. Screw an extension pole into the handle of the roller frame.
Hang a metal paint roller screen from the inside lip of the bucket.
Dip the roller's nap in and out of the paint until the nap is filled with paint.
Paint the wall from left to right in long up-and-down strokes with the roller.
Reload the roller with paint after each roller-width of wall space has been painted.
