TPR2 Fireshell is a high-performance intumescent paint engineered for spray foam insulation and other applications where a thermal barrier is required. It’s easy to apply, environmentally friendly, and helps keep your building safe and code-compliant.

Intumescent Paint for Spray Foam Insulation

TPR2 Fireshell F10E is a water-based, single-component, intumescent coating designed for interior use over spray polyurethane foam (SPF). This TPR2 thermal barrier coating expands up to 2000% under fire exposure, forming a char layer that slows flame spread.

• Meets building codes as an alternative thermal barrier for open-cell and closed-cell SPF.
• Non-toxic, low VOC, and eco-friendly for safe installation.
• Tintable or top-coatable for a clean finish in residential or commercial spaces.

Installation & Application Instructions

Follow these steps to get the best results from your installation:

1. Surface Prep: Ensure foam is clean, dry, and free of dust or oil. Lightly scuff glossy foam surfaces for better adhesion.
2. Conditions: Apply between 50–95°F, with humidity below 70%. Keep product above 62°F before use.
3. Application: Spray, roll, or brush to the recommended wet film thickness (18–20 mils). Multiple coats may be required.
4. Drying: Allow to dry completely between coats. Full cure takes 2–4 weeks.
5. Finishing: Can be left white or top-coated with latex paint for aesthetics.

Tip: Use professional-grade airless spray equipment for consistent coverage and code compliance.
