Pedigree doesn’t necessarily mean better (whether it be art, furniture or dogs). Consider an “unknown” artist or designer and buy based on shape, comfort and how the art or furniture works for you and your needs. The most humble objects can have the most soul and be the most beautiful thing in a room. Do not be afraid to mix high and low price points. Not everything must be precious to be important. The opposite can be said with splurging on something that you really love.
Lucky for you, there are paints to help. Rust-Oleum makes a "mold and mildew-proof" paint for about $27 a gallon that can protect those mold danger zones. You can fight those nasty germs with Sherwin-Williams' Paint Shield, which costs about $85 per gallon. Unlike other microbial paints, this formulation is EPA-certified to kill more than 99.9% of surface bacteria in less than two hours, including E. coli and staph.
