HydroCleanis a safe and biodegradable cleaner that, when diluted with water, wets and penetrates into the existing substrate or coating; this allows all loose material and any liquid contaminants and oils to be flushed from the surface. The cleaning action of HydroClean helps promote adhesion of primers and the PremiumCoat Roof System to existing substrates. Available in 1-gallon and 5-gallon units; one gallon of HydroClean makes 11 gallons of cleaner. For more information, visit www.hydrostop.com or stop by booth 707.
