How to Fix the Botchy Painting of an Interior Wall
- 1). Prepare the space. Use cloth drop cloths to protect the floor from any spills or paint splatters and adhere painter's tape securely to all trim work.
- 2). Apply primer to all drywall patches, filled cracks and holes, or the entire surface if the whole wall is blotchy. Primer will seal the surface and prevent uneven absorption of the paint. Use a 3/8-inch nap roller for smooth walls or a ½-inch nap roller for textured walls to apply primer directly to the uneven drywall. Feather the edges outward with the roller to avoid a heavy paint line.
- 3). Paint the corners and around the trim with a brush, then immediately follow with a 3-inch roller to cover blotchiness. Roll the paint out as close as possible to the trim before it dries. Finish working in one area before moving on to the next.
- 4). Roll the full height of the wall. To avoid uneven paint coverage and lap marks, use a paint roller attached to an extender to roll the entire height of the wall. Always keep the edge of the paint wet.
