Hilti Fire Finish 120+ CFP-SP WB's optimized formula ensures market-leading wet-film thickness buildup per pass, meaning you can safely apply 65 mils of this fire protection product (wet) per pass. Additionally, the glass fiber-free formulation ensures a premium aesthetic finish once applied. This feature reduces the amount of post-process sanding needed with other steel protection products, thus decreasing the total installation cost.

Modern design practice has increasingly incorporated architecturally exposed structural steel, or AESS.  Originally used by structural engineers as a highly elaborate exoskeleton, AESS has evolved into an outlet for both engineers and architects to integrate components of their work into the visibly finished structure.  If these exposed design elements are also part of the primary structural components of the building, the integrity of the structural steel must be protected with an intumescent fire protection coating.


Architects can specify Hilti Fire Finish 120+ CFP-SP WB fiber-free spray with confidence knowing that they will not only get the superior aesthetic finish they desire, but also the dependability and reliability of a fire finish product tested to ASTM E119 and certified for up to a 4-hour fire rating.  Contractors can see a productivity gain by choosing Hilti’s Fire Finish for their next job.  Installers will notice the product’s high wet-film thickness feature allowing them to apply more product per pass and less overall coatings compared to thinner competitor products. 

For superior fire protection of AESS and a distinctive aesthetic finish, look no further than Hilti Fire Finish 120+ CFP-SP WB for your next job.
