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

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 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.
