Surface must be free of oil, grease, loose rust and flaking paint. Use degreaser and light sanding or wire brushing to prepare surface if these conditions are present. Coat surface with product by spraying, brushing or dipping. For best results, use at temperatures above 21º C. If surface is going to be painted, allow treated surface to dry thoroughly for 2 hours, then apply oil based, urethane or epoxy paint. If the treated area will not be painted afterwards, apply directly to surface and allow it to work for 1-2 minutes before rinsing treated area with fresh water. Towel dry surface and apply an appropriate protective oil. If sprayer is used, pump clean water through for about 1 minute before storing.
