is similar in appearance to mortar and can be troweled to a smooth finish
providing a weather resistant, non-shrinking fire rated seal.
APPLICABLE STANDARDS:
UL 1479, Firstops, Fire Tests of Through-Penetration Firestops. ASTM
E-814, Fire Tests of Through-Penetration Fire Stops. ASTM E-119, Fire
Tests of Building Construction and Materials.

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.
Nelson CMP is available
through authorized distribution worldwide. Contact Nelson for the location
of the nearest distributor who is able to provide cost and availability
information.
