Typical recommended specification range
Dry film thickness:
0.5 mm to 4 mm per coat.
All steelwork must be coated at the correct film thickness to achieve the required fire rating. Refer to the current thickness tables. For details, consult your local JOTUN office.
Recommended: use a two-component spray pump to control typical application thickness at 3 to 4 mm; this range achieves an ideal balance among film formation quality, surface finish and thickness control. In actual application, WFT may be appropriately increased according to operating conditions such as steel structure configuration, geometry, application environment parameters, pump model, operator proficiency, application accessibility and primer type. Subsequent coats may be applied after the material is fully cured, generally recommended 60 min after application; the specific time shall be adjusted according to on-site temperature, humidity and other environmental parameters.
Maximum WFT is the highest film thickness at which the coating system can be applied without sagging. If a thicker coat is applied, sagging may occur, and recoating intervals, drying and handling times will be prolonged.
When spraying with a single-component pump, dilution is required. WFT can reach 1.5 mm, depending on the amount of thinner added, pump type, pump settings, spray technique and other factors.
Refer to the application guide for more detailed information.
Maximum permitted dry film thickness (BS and EN certificates)
Where measured thickness exceeds the limit, the measured thickness must be reduced by suitable means, based on the maximum thickness permitted by the profile and layout of the specific section.
I/H beam, 3 sides: 9.02 mm; I/H beam, 4 sides: 9.02 mm; I/H column, 4 sides: 11.06 mm; CHS & RHS column: 13.77 mm
For further information, see the Application Guide.
Surface Preparation

| Coated surface | A clean, dry and sound compatible primer. | |
| Carbon Steel | Power tool cleaning to St3, with a defined roughness profile. | Sa 2½ (ISO 8501-1) |
This product may be applied by the following methods
| Spray: | Use two-component spray equipment with heating function. A single-component airless spray pump may also be used. For more information, refer to the application guide. |
| Brush: | For repair or edge finishing of small areas. |

| SteelMaster 1200HPE Comp B Exterior Intumescent Steel Fire Protection 1200 HPE, Component B | 1 part |
Before use, each component shall be pre-conditioned at 20–30°C. Stir or mix thoroughly with a power mixer before application.
| Thinner: | Jotun Thinner No. 7 | /Jotun Thinner No. 17 |
| JOTUN Thinner No. 7 | JOTUN Thinner No. 17 / JOTUN Thinner No. 10 | |
| Maximum thinning: | 4 % |
When two-component spray or brush application is used, no additional dilution is required. For single-component airless spray pumps with a hopper, the dilution ratio is usually 1%–3% of total volume; the recommended maximum dilution ratio is 4%.
Depending on pump type and environmental conditions, dilution may not be required, for example when using a spray pump with hydraulic piston and follower plate in warm climates. Dilution affects sag resistance and delays drying time.

| Dry/cured to service | 30 h | 24 h | 16 h | |
For the maximum recoat interval, refer to the Application Guide (AG) for this product.
The minimum drying recoat interval is for self-recoating. See the additional guidance for the finish coat.
All drying times are measured at a WFT of 4000 µm, under controlled temperature and relative humidity below 85%.
Topcoat:
The minimum overcoating interval before topcoat application is 16 h. The coating shall reach handle dry and shall not show marks on the surface when DFT is measured with a DFT gauge. Before topcoat application, the application contractor must ensure the dry film has reached the specified DFT.
Minimum product application temperature down to 5°C (41°F). For improved application performance and drying, steel and air temperature should be above 10°C.
| Touch Dry | The state at which light finger pressure leaves no mark or stickiness. |
|---|---|
| Handle dry | The minimum time after application before handling will not damage the film. |
Minimum recoat interval after drying: the recommended minimum interval before applying the next coat.
Dry/cured to service: the minimum time before the coating can be permanently exposed to a specific environment/medium.
| Paint temperature | 15 °C | 23 °C | 40 °C |
| Pot Life | 45 min | 40 min | 25 min |
Pot life does not apply to two-component spray equipment. For single-feed airless spray, the mixed paint shall be used as soon as possible. Due to the exothermic reaction, the larger the quantity of paint mixed, the shorter the pot life.
Depending on the actual exposure conditions in service, this product may be used with various primers and topcoats. Some reference systems are listed below. For specific systems, contact JOTUN.
| Previous coat: | Epoxy, zinc phosphate epoxy, modified epoxy, zinc-containing epoxy |
| Subsequent coat: | Acrylic, acrylic polyurethane topcoat, polysiloxane |
Primers and topcoats used in systems with this product shall be approved by JOTUN. Consult JOTUN for the latest list of approved primers.
