When a project’s budget can’t accommodate metal wall finishes, consider coatings. Stolit Milano from Sto Corp. is a low-VOC, water-based acrylic finish. It resists mildew and can be used on interior and exterior walls to create textured or smooth-faced surfaces that mimic the look of metal. Sto Corp. recommends using two or three coats to create the desired effect. Custom colors are offered.
