Installers of Fireproof / Fire Retardant Finishes for Fireproofing Spray Polyurethane Foam

Polyurethane spray foam insulation is widely used across industrial and commercial facilities due to its excellent thermal performance and air-sealing capabilities. However, one critical drawback is that spray polyurethane foam (SPF) is highly flammable when left unprotected. To mitigate this risk and meet building code requirements, it must be coated with a fire-retardant paint system designed specifically for exposed foam.

At Induspray, we specialize in applying industrial-grade fireproofing coatings over SPF insulation in factories, warehouses, institutional buildings, and other facilities. Our expert team ensures that your foam surfaces meet strict fire safety regulations—while maintaining an attractive, uniform appearance.

Why Fireproof Polyurethane Foam?

Exposed SPF insulation can ignite quickly and spread flames rapidly. Applying the correct fire-resistant paint protects your facility and helps you:

  • Comply with building and fire codes (IBC, NFPA, Ontario Building Code, etc.)
  • Meet insurance provider requirements for foam insulation
  • Increase fire resistance and delay flame spread in the event of an emergency
  • Improve aesthetics with a uniform matte white finish
  • Avoid costly retrofits or code violations during inspections

Where We Apply Fireproofing Coatings

We work in a variety of facility types across Ontario and Eastern Canada.

We perform fireproofing of sprayed-on polyurethane foam in these industrial, commercial, and institutional locations:

  • Schools
  • Colleges
  • Nursing Homes
  • Child Care Centers
  • Hospitals
  • Penal Institutions
  • Apartments
  • Hotels
  • Factories
  • Warehouses
  • Retail Stores
  • Restaurants
  • Utilities
  • Railroad & Transportation Companies
  • Oil & Chemical Installations
  • Military Installations
  • other facilities

Whether it’s a retrofit project or new construction, Induspray ensures your fireproof coating is applied safely, professionally, and with long-lasting performance.

Our Fire-Retardant Coating System

We use only UL-classified and code-approved fire retardant coatings for spray foam insulation. These coatings are:

  • Water-based intumescent or non-intumescent fire-rated paints
  • Formulated for adhesion to porous foam textures
  • Designed to expand or insulate against heat during a fire
  • Non-yellowing and highly durable in industrial environments
  • Safe, low-VOC, and fast-drying for minimal facility downtime

Each product we use is selected based on your facility’s location, type of SPF used, and fire protection rating required (Class A, ASTM E84, etc.).

Our Fireproofing Spray Process: From Site Visit to Final Coating

We follow a proven five-step process to ensure precision, safety, and compliance.

1. Site Evaluation

Our team assesses your facility’s spray foam coverage, substrate condition, ventilation, and access restrictions.

2. Surface Preparation

We carefully clean and prepare the foam surface. Depending on site conditions, this may include brushing, vacuuming, or lightly abrading the surface to ensure optimal coating adhesion.

3. Application of Fire-Retardant Paint

Using airless sprayers or specialized equipment, we apply the coating to manufacturer-recommended thicknesses. Multiple coats may be needed to meet fire rating specifications.

4. Quality Assurance

We verify mil thickness using digital gauges and perform a final inspection to ensure coverage is complete and the finish meets visual and fire-rating standards.

5. Clean-Up & Documentation

Our crew cleans the job site thoroughly and provides documentation for your records—including data sheets, MSDS, and any required certifications.

What Our Clients Say

Induspray painted 4 large stamping presses for us and were able to complete the work with minimal disruption to our production schedule. First rate equipment painters.

Andy and his crew cannot be more recommended. In all our dealings, he was professional and honest. The quality of the work was excellent, and the price was reasonable. Thanks again.

A professional painting contractor that I would recommend to anyone.

The crew from Induspray did a great job for us. We had our entire warehouse ceiling painted (at over 85,000 sqft), and they were in and out in less than the originally estimated time. I would definitely recommend them.

All the walls in our plant were painted and it all looks great now. Very happy with the work and the price we obtained.

FAQs for Industrial Fireproofing Spray Foam Insulation

Yes, spray foam insulation can be painted, but only with compatible coatings. In Ontario, especially for industrial applications, it’s crucial to use fire-retardant or intumescent paint systems to comply with building code regulations and improve fire resistance.

Fireproofing polyurethane foam typically requires intumescent paint or fire-retardant coatings. These specialized paints expand when exposed to heat, creating a protective barrier that delays ignition and reduces smoke development.

Fireproofing spray foam typically depends on the size of the area, the type of intumescent coating used, and the complexity of the application. For an accurate estimate, a site assessment by professional industrial painters is recommended.

Not always. While fire-retardant paints offer some protection, Ontario Building Code may require a thermal or ignition barrier for exposed spray foam in specific environments. Always consult a certified contractor to ensure code compliance.

When professionally applied and maintained, fireproof coatings on spray foam can last 10–15 years or more, depending on environmental conditions, exposure, and wear. Regular inspections help ensure ongoing fire protection.

Yes. Many insurers in Ontario require fire protection upgrades like intumescent coatings on spray foam insulation in industrial settings. Proper fireproofing not only enhances safety but can also reduce insurance premiums.

Industries that often require fireproofed spray foam include:

  • Manufacturing plants
  • Warehouses
  • Food processing facilities
  • Cold storage and freezer buildings
  • Auto repair and service garages

These environments often contain combustible materials or require strict adherence to safety codes.

Modern intumescent coatings are low-VOC, non-toxic, and safe for use in industrial facilities across Ontario. They are designed to meet both environmental and occupational safety standards.
