My dining room wall consists of plaster board over top of horse hair plaster. Over time there were a couple of places where the wall had chipped away. To hide the defects I reused some sample paints I had left over from other projects. Careful placement of furniture and making wall boxes did the job. The smaller cosmetic flaws were disguised by the faux brick painting. Using painters tape for the bricks, and my fingers for the edges did the job. Love the results.
