Gus Reingold / Fireproofing Contractor

We couldn't be happier with the exceptional service provided by National Fireproofing Supply. Not only did they exceed our expectations, but they did so with professionalism and efficiency. Their products were delivered promptly, and at a fair price. We highly recommend their products to anyone in need of fireproofing solutions.

Tyler Olson / Contractor

We received your sample in the mail today, thank you very much! We actually purchased 2 pails of the PF-2 and used it last week and it worked great on our clients deck. You guys have earned our business going forward.

Steven Watts / Deck Builder

Our downtown projects often require replacing fireproofing on existing steel structures, and dealing with licensed contractors can be costly and inefficient. That's why we turn to National Fireproofing's Contego's High Solids intumescent paint - it's easy for our team to apply on-site, saving time and money without compromising on safety. With this product, we can confidently protect any structure, big or small.

Ryan Stevenson / Fire Security Services

Flamex PF-2 is a game-changer for treating wood for construction. Applied easily with a garden sprayer, it provides the fire retardant protection you need.
