Braycote 194 is designed to protect unpainted metal surfaces from the effects of indoor or shed exposure for periods up to one year. It is non-corrosive and readily wets the surfaces of commonly used metals, leaving a continuous film after evaporation of the solvent. This product may be applied by spray, dip or brush. A gallon will cover approximately 300 to 1,600 square feet, leaving a film 1 to 4 mils thick, depending upon method of application and surface geometry. Optimal performance can be achieved only when the metal surfaces to be protected are clean, dry and free of rust, oil and mill scale. It is recommended that the metal substrate and ambient temperature be 50-95°F (10-35°C) at the time of product application.
