MONOKOTE MK-1000 HB Single Component, Spray Applied, Mill-Mixed Fire Resistive Plaster

MONOKOTE® MK-1000 HB is a single component, spray applied, mill-mixed fire resistive plaster. It has approval for use on structural steel members and fluted decking to provide up to four hours of fire protection, and on flat plate cellular decking for up to three hours with SPATTERKOTE® SK-3.

The product has been designed to obtain bond strengths in excess of 1,000 psf making it an attractive material for meeting the 2009 IBC building requirements for bond strength for buildings in excess of 420 feet tall. The capability of meeting the bond strength requirements with a high yielding spray applied fire resistant material makes MONOKOTE® MK- 1000 HB fire resistive plasters a cost effective option.

Features & Benefits

MONOKOTE® cementitious fireproofing offers many significant advantages to the architect, owner, applicator and building occupant. These include:

• Proven in-place performance
• Low in-place cost
• Fast, efficient application
• UL fire tested and factory inspected
• Building Code compliant

Steel & Concrete Surfaces

• Prior to the application of MONOKOTE® MK-1000 HB fire resistive plasters, an inspection shall be made to determine that all steel surfaces are acceptable to receive fireproofing. The steel shall be free of oil, grease, rolling compounds or lubricants, loose mill scale, excess rust, noncompatible primer, lock down agent or any other substance that will impair proper adhesion. Where necessary, the cleaning of steel surfaces to receive fireproofing shall be the responsibility of the general contractor.
• The project architect shall determine if the painted/primed structural steel to receive fireproofing has been tested in accordance with ASTM E119, to provide the required fire resistance rating.
• Many Fire Resistance Designs allow the use of painted metal floor or roof-deck in place of galvanized decking. Painted decking must be UL listed in the specific fire resistance designs and must carry the UL classification marking. Consult your local GCP sales representative for details.
• Prior to application of MONOKOTE® MK-1000 HB fire resistive plasters, a bonding agent, approved by the fireproofing manufacturer, shall be applied to all concrete substrates to receive MONOKOTE® MK-1000 HB.
• Fireproofing to the underside of roof deck assemblies shall be done only after roofing application is complete and roof traffic has ceased.
• No fireproofing shall be applied prior to completion of concrete work on steel decking.
• Other trades shall not install ducts, piping, equipment, or other suspended items until the fireproofing is completed and inspected.
• Other trades shall install clips, hangers, support sleeves, and other attachments that penetrate the fireproofing, prior to application of the fireproofing.
