Tips For Painting Basement Walls
Basement walls aren’t like the other walls in your house. They are part of the foundation, and because they lie below grade, they are subject to moisture produced by condensation and seepage. Painting basement walls can prove to be a challenging job, but following a few simple tips may help prevent some common mistakes. Adequate preparation is one of the most important areas overlooked when painting basement walls. Waterproofing treatments often work best when applied before the paint and primer. Applying two coats of good-quality primer will usually prevent stains from showing through the finished paint. Basements typically have poor ventilation, and care must be taken to properly vent fumes. Professionally painting basement walls usually begins with a well-prepared surface. Unpainted concrete walls typically require more surface preparation than finished drywall.
Begin by thoroughly cleaning the basement walls with soap, water, and chlorine bleach if necessary. Concrete walls should also be swept or vacuumed to remove loose mortar and dust. Any cracks or crevices must be repaired before applying a waterproofing treatment. Some waterproofing treatments cannot be applied over paint so it is usually best to put them on first. Apply the treatment with a brush, long-nap roller, or sprayer according to the manufacturer’s directions. Remember to cover floors and furniture with a non-porous drop cloth during this procedure. Allow the treatment to dry completely between coats and before painting. Placing a portable fan in the room may help speed the drying process.
