We provide both spray- and trowel-applied fireproofing to exposed structural steel surfaces, roof and floor assemblies, columns, concrete services, and joists in both industrial and commercial environments.

Spray-on fireproofing methods involves the spraying of various products onto construction materials to improve resistance to fire, while decreasing chances of weakening, burning or melting under extreme heat. While trowel-applied fireproof coatings optimize safety and performance, all while mitigating the risks of downtime, damage and injury.

We have completed many difficult projects without incurring unjustified cost overruns, which differentiates us from our competitors. We were the “fireproofing” contractor of choice for a new dormitory at one of the nation’s top research universities.   We also applied intumescent fireproofing, plus low-density cementitious (spray-applied) fireproofing and high-density cementitious (trowel-applied) fireproofing and epoxy and general paint in The University of Virginia’s John Paul Jones Basketball Arena, the largest stadium of its kind in VA!

Services include:

  • Intumescent Fireproofing
  • Spray-applied cementitious trowel-applied fireproofing
  • Pneumatic, spray and troweled applications


  • Dense concrete and lightweight cementitious
  • Corrosion under fireproofing management (CUF)

“G.C. Zarnas was the official painting and fireproofing contractor to Barton Malow, the general contractor for the John Paul Jones Basketball Arena located on the University of Virginia campus in Charlottesville, VA. The team worked diligently to fashion a modern arena that also blends with the historic campus.  Read more about this project featured in Construction Review Magazine.”
