For walls with smoke damage, the best paint color to use is a high-quality, stain-blocking primer followed by a fresh coat of paint in a light color such as white or a light gray. The most affordable option for covering smoke damage is to use a primer that specifically addresses smoke stains, followed by a cost-effective paint in a light color. Light colors help to mask any remaining discoloration from the smoke damage and create a clean, fresh look in the space.

When dealing with smoke-damaged walls, it is crucial to properly clean and prepare the surface before painting. This includes washing the walls with a mixture of water and trisodium phosphate (TSP) to remove soot and grime, as well as repairing any damage or imperfections in the wall surface. Once the walls are clean and dry, applying a stain-blocking primer will help to prevent any remaining smoke stains from bleeding through the new paint.

When selecting a paint color, light shades are recommended for their ability to brighten up a room and disguise any remaining discoloration. White is a popular choice as it provides a clean, fresh look and can help to make a space feel larger and more open. Light grays are another excellent option, offering a modern and versatile aesthetic that complements a variety of decor styles.

In conclusion, when painting over smoke-damaged walls, the best approach is to use a high-quality, stain-blocking primer followed by a light-colored paint such as white or light gray. By properly preparing the walls and selecting the right products, you can effectively cover smoke damage and create a fresh, clean look in your space without breaking the bank.
