Surface Preparation

Cleanliness

• Remove salts, detergents and other contaminants by high-pressure fresh water washing.

• Abrasive blast clean to Sa 2½ (ISO 8501-1) / SP 10 (SSPC) minimum.

• Zinc-rich paint surfaces: use non-metallic blasting media (corundum, garnet, etc.).

• Use approved primers.

• Remove oil, grease and other contaminants by cleaning with a suitable cleaner.

• Remove dust, blast abrasives and loose material.

• The surface must be dry and clean before application.

- For approved substrates other than carbon steel, additional surface preparation steps may be required; refer to Hempel's application instructions for details.

• If the surface is rough and unpolished, clean with power tools to St 3.

• For further details, refer to the separate Hempel document Surface Preparation Guide.

Maintenance and repair

• For small areas where abrasive blasting is not possible, clean by hand or with power tools.

Application

Thinner

Not recommended

HEMPEL's Tool Cleaner 99610

Recommended method

Nozzle pressure: 20 MPa

Airless Spray

Nozzle tip size: 0.43-0.58 mm. If brush or roller is used, multiple coats are required to achieve the specified dry film thickness. Thinning is generally not recommended. The spray parameters are indicative and may be adjusted according to site conditions. The pressure values apply to material at 20 °C. (*For other application methods, consult the company representative).

Film thickness

The dry film thickness of the fire protection coating depends on the required fire resistance rating and the section factor of the steel structure; contact your local Hempel representative. The maximum thickness per coat is 1500 µm [60 mil] dry film thickness, equivalent to 2000 µm [80 mil] wet film thickness. For further details, refer to the Application Instructions.

Application conditions

• The surface to be coated must be clean and dry, and its temperature must be at least 3 °C [5 °F] above the dew point to avoid condensation.

Notes

• Stir thoroughly before use.

Drying and recoat

Product compatibility

- Previous coat: according to Hempel's specification. Hempel-approved primers only. Consult the Hempel representative for information on approved primers.
