Bridge Paint is a rich micaceous iron-oxide paint that is perfect for outdoor or indoor use. It creates a beautiful and extremely durable speckled finish. It is best applied with a brush and the cross-hatching technique but can be rolled on as well for an easier finish. It is typically applied onto exterior metal work like exposed pipes, sign boards or any metal framework. However, the paint is very popular on everything from walls, doors, furniture and planters. When painting metal (interior or exterior) it is best applied over an undercoat of murobond metal primer.
