5. INSTALLATION:Choose the appropriate firestop system using Nelson application data sheets, the UL Fire Resistance Directory, Factory Mutual Approval Guide, or other directories of acceptable designs. Thoroughly mix dry Nelson CMP with water to achieve a uniform texture. For installation without forming, use 1:3.5 water/compound mix ratio. For quicker installation with forming, use 1:3 water/compound ratio. Avoid extreme ratios. Material can be pumped, troweled or hand packed into the opening. Floor or wall penetrations with large open areas may require some temporary forming. Nelson CMP sets up in about four hours and cures completely in approximately four weeks.
