Different surfaces respond in varied ways to paint. For example, wood and concrete both absorb. On the other hand, deciding what kind of paint to use on metal can pose a unique challenge. Unlike wood or concrete, metal isn't absorbent, which necessitates an understanding of the paint options that will adhere best to those surfaces and guarantee aesthetic longevity. There are paints with defined compositional bases created for specific surfaces and even multi-surface paint options with universal capabilities. Ultimately, the type of paint you choose to use will depend on the type of surface you're painting.
