MONOKOTE MK-6 HY/MK-6s Single Component, Spray Applied, Mill-Mixed Fire Resistive Plaster.

MONOKOTE® MK-6 HY and MK-6s are single component, spray applied, mill-mixed fire resistive plasters. MK-6 HY and MK-6s have 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. 
Note: MONOKOTE® MK-6 HY and MK-6s afford the same level of the fire protection at identical protection thicknesses. By simply specifying MONOKOTE® MK-6, the fireproofing subcontractor can select the product that will provide the most efficient fire protection for the specific project conditions.

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-6, 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-6, a bonding agent, approved by the fireproofing manufacturer, shall be applied to all concrete substrates to receive MK-6.
• 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.
