FIRESTOP COMPOUND

Technical Data

  • Product Description
    Nelson Compound (CMP) is a cementitious material that is mixed with water. It is similar in appearance to mortar and can be troweled to a smooth finish that provides a weather resistant, non-shrinking fire-rated seal.
  • Application
    CMP Compound should be thoroughly mixed with water to achieve a uniform texture. Clean adjacent surfaces of opening prior to installation. For installation without forming, use 1:4 waker/compound mix ratio. For quicker installation with forming, use 1:2.5 water/compound ratio. Avoid extreme mix 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. Actual installation should be in accordance with the appropriate Nelson application system drawing.

FIRESTOP SEALANT

Technical Data

  • Product Description
    Nelson Firestop Sealant (CLK) is a family of one part silicone flexible sealants, used to protect from the spread of fire, smoke, gases and water. It is designed for applications of through stop penetrations and in construction joints. It is offered in two forms, a non-sag caulk which can be troweled and a self-leveling grade suited for floor applications.
  • Application
    CLK N/S (non sag) sealant can be applied using a conventional caulk gun, bulk loader or by trowel. For larger applications it can be pumped directly from the pail. Nelson CLK S/L (Self-Leveling) is fluid and can be poured into place in floor applications. Actual installation 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).
  • Availability
    AA529 - Non/sag - 10.3 oz Tube (304ml) 12/Ctn
    AA539 - Self Leveling - 10.3 oz Tube (304mI) 12/Ctn
  • Uses
    CLK is applicable for non-combustible pipe through stop penetrations and for floor to wall, floor-to-floor and head of wall applications. It is flexible and is ideal for applications where joint expansion and contraction or vibration can occur.
