When you decide to employ tin ceiling tiles as a dramatic type of design in your home, it's important to care for the tiles properly to make sure they look beautiful for years to come and don't require replacement. The leading cause of damage to tin ceiling tiles whether they're on a ceiling or on any other surface of the home is water damage and applying at least two coats of polyurethane will ensure they are protected in the event a water pipe breaks in the home. An oil-based paint is also recommended for tiles that are painted because they are susceptible to rust.
