What is MK6 HY?
What is MK6 HY?
Monokote® Type MK-6/HY is a single component, millmixed fireproofing plaster which requires only the addition of water on the job site to form a consistent, pumpable slurry. Type MK-6/HY is designed for use on structural steel columns, beams, joists, trusses and floor and roof decking.
What is Monokote MK6?
MONOKOTE® MK-6 HY and MK-6s are single component, spray applied, mill-mixed fire resistive plasters. 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.
Can monokote Mk 6 be painted?
PHYSICAL/CHEMICAL PROPERTIES Monokote MK-6s and MK-6/HY Structural Steel Fireproofing exhibit the properties indicated in Table 1. FIRE RATING Underwriters Laboratories, Inc. Installation PREPARATORY WORK Steel must be free of oil, grease, loose mill scale, paint or any other substance that can impair proper adhesion.
How do you mix Monoprote fireproofing?
Mixing
- MONOKOTE® Fireproofing shall be mixed by machine in a conventional, plaster-type mixer or a continuous mixer specifically modified for cementitious fireproofing.
- Using a suitable metering device and a conventional mixer, all water shall be first added to the mixer as the blades turn.
How much does spray fireproofing cost?

| Equipment | $14 | $13 |
| Column cover | —– | $1,575 – $2,205 |
Is fireproofing toxic?
The materials used for fireproofing can be quite dangerous because of the asbestos contents. Apart from asbestos, fireproofing materials contain other potentially toxic materials.
Do braced frames require fireproofing?
requirements of the code, the structure is required to achieve a two-hour fire resistance. Because the steel braced frame is designed primarily for high seismic demands, the members are over-sized for the fire limit state where the applied loads are significantly reduced.
Can spray applied fireproofing get wet?
Spray applied fireproofing is usually not suitable for surfaces exposed to moisture or high humidity levels. The moisture and humidity will deteriorate the products. In addition, the moisture may cause mold growth due to the porous nature of SFRM.
How expensive is intumescent paint?
As intumescent fire resistive coatings can be quite expensive ($4 to $12 per square foot, depending on the application and required rating), measuring the coating thickness can play an important role in controlling the application costs.
How do you fireproof?
The most common way of fireproofing is by spraying low-density fibers or cementitious compounds, called spray-applied fire-resistive materials or SFRM. These sprays can be applied wet or dry, in coatings of the desired thickness, to provide heat resistance to steel.
Is fire a retardant?
A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. Fire retardants may also cool the fuel through physical action or endothermic chemical reactions. Fire retardants are available as powder, to be mixed with water, as fire-fighting foams and fire-retardant gels.
