To prevent mildew from forming on bathroom walls, Mauro points out that it’s important to keep the shower vent clean and use it for at least 30 minutes after a shower. If mildew appears, take a bucket of water with a small amount of bleach in it, dip a rag into the bucket, and gently clean the walls to avoid damaging the paint.

Mauro painted the walls with Behr Marquee interior paint in Gray Shimmer with an eggshell finish (behr.com/consumer). The paint is mildew resistant. Mauro applied two coats to ensure even coverage.

The other materials Mauro used for this job, including the paint brushes, tape, trays, and drop cloths, can all be found at home centers.
