LBS3™ Intumescent Sealant

Technical Data 

Product Description

Nelson Firestop Sealant (LBS3™) is an elastomeric, water based, intumescent, fire protective sealant. It is designed for applications of through firestop penetrations and construction joints. It is used to seal against the spread of fire, smoke, gasses and water. 

Application

LBS3™ is ideally suited for through firestop penetrations of non-combustible pipe, insulated pipe and combustible pipe such as PVC, PEX, CPVC and ABS, in floors or walls. LBS3™ sealant can be applied using a conventional caulk gun, bulk loader or by trowel. Actual installation of Nelson LBS3™, may vary according to the type of firestop application. Apply the required depth of sealant beginning on the edge of the opening (use over various backing materials as required). Insure that the sealant makes complete contact with the inside surface of the opening and also the surface of the penetrating item(s).
