The recommended dilution rate on the bottle is one part Roof & Deck to six parts water; however, some of our clients are finding that they can dilute up to 20:1. This dilution rate should be considered a starting point. If rinsing with low water pressure, this dilution rate may be needed. If using with good water pressure, dilution rates may be adjusted. Rates as high as one part Roof & Deck to eight parts water are currently being used by many professional contractors. When cleaning painted or vinyl starting dilution rates should start at one part Roof & Deck to twentyfive parts water. Top • What pressure is recommended when using Roof & Deck Concentrate?
