MONOKOTE® Z-106/G is a gypsum based cementitious fireproofing designed to meet commercial and industrial fire protection requirements on structural steel members, floor/ceiling and roof/ceiling, and wall assemblies.

MONOKOTE® Z-106/G is designed to meet interior exposed product requirements where the superior durability and water resistance of Portland cement based products is not required.

Product Applications

MONOKOTE® Z-106/G can be used for interior, exposed applications where light abrasion and damage resistance are desired:

  • Elevator shafts
  • High bay light manufacturing areas
  • High bay mechanical rooms


MONOKOTE® Z-106/G offers the following advantages to the architect, owner, applicator and building occupant.

  • Low cost - MONOKOTE® Z-106/G is a low cost, medium density product for interior, dry environments subject to intermittent traffic and physical contact.
  • Durability - Higher gypsum binder content improves damage resistance and helps maintain the fire resistance for the design life of the building.
  • Quick set - May be used with our patented Injection System for quick set and fast double on multiple pass applications.
  • Applicator friendly - Low pumping pressures allow use of small diameter hoses for increased maneuverability and greater pumping distances.
  • Aesthetics - Can be spray applied to a fine texture finish.
  • Non-toxic - The factory-mixed blend of common gypsum, Portland cement and inert materials requires only the addition of water for mixing and application.

Steel & Concrete Surfaces

  • Prior to the application of MONOKOTE® Z-106/G Fireproofing, an inspection shall be made to determine that all steel and concrete surfaces are acceptable to receive fireproofing. The steel to be fireproofed shall be free of oil, grease, excess 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.
  • Prior to application of MONOKOTE® Z-106/G, a bonding agent approved by the manufacturer shall be applied to all concrete surfaces to receive MONOKOTE® Z-106/G.
  • 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.
  • No fireproofing shall be applied prior to completion of concrete work on steel decking.
  • Fireproofing to the underside of roof deck assemblies shall be done only after roofing application is complete and roof traffic has ceased.
