Indoor / Outdoor SystemsNon-intumescent thick-film systems
Non-Intumescent Fire Protection Coating
Thick-film fire protection coating systems for steel structures requiring higher dry film thickness and defined fire-resistance duration.
- System options
- Indoor / outdoor
- Substrate
- Steel preparation and compatible primer required
- Film build
- Project-specific dry-film thickness
Overview
Non-intumescent thick-film systems are considered for structural-steel projects where the project design calls for a substantial protective coating build and defined exposure conditions.
Indoor and outdoor systems need separate evaluation; a coating thickness or construction detail from one system cannot be carried to another without the appropriate supporting record.
- Indoor system
- Define the steel section, approved primer, dry-film build, curing and interior exposure.
- Outdoor system
- In addition to the steel and film build, verify the outdoor exposure, durability and compatible protective finish.
Typical applications: Steel fire protection, Outdoor exposure, Industrial structures.
Specifications and test basis
| Property | Value | Basis |
|---|---|---|
| System type | Indoor and outdoor thick-film options | Supplied non-intumescent work instructions. |
| Substrate condition | Steel preparation and compatible primer required | Supplied work instructions. |
| Coating build | Project-specific dry-film thickness | Selected from the applicable design and supporting report. |
| Exposure selection | Indoor versus outdoor system must be identified | Supplied work instructions. |
Values are drawn from the specified product grade or supplied test record. Confirm the complete method, sample configuration and operating conditions before project use.
Handling and selection limits
Handling / storage
- Define the steel section, primer and target dry-film build before application planning.
- Check curing, topcoat and weather exposure requirements for the selected indoor or outdoor system.
Selection limits
- No fire-resistance duration is published here because the extracted work instructions alone are not a public rating certificate.
- Use only the test evidence specific to the selected system and steel configuration.

Product FAQ
How do indoor and outdoor systems differ?
Exposure, durability, primer/topcoat selection, curing and the evidence package must be reviewed separately.
Can I select thickness from a previous project?
No. Thickness must follow the applicable project design and supporting test or approval documentation.
