Preparation
- Remove salts, detergents and other contaminants by high pressure fresh water cleaning
- Abrasive blasting to min. Sa 2½ (ISO 8501-1) / SP 10 (SSPC)
- Zinc coated surfaces: use non-metallic blast media (corundum, garnet, etc.)
- Use approved primer
- Remove oil, grease and other contaminants by suitable detergent cleaning
- Remove dust, blast media and loose materials
- The surface must be dry and clean prior to application
- For approved substrates other than Carbon Steel, the substrate may require other surface preparations, consult Hempel's application instructions for detailed information
- Minor areas can be cleaned by power tool to St 3 provided the surface is roughened and not polished
- Consult Hempel's separate Surface Preparation Guidelines for more details
- Minor areas may be hand or power tool cleaned instead of abrasive blasting
Application
Apply with brush, roller, or airless spray (Nozzle pressure: 200 bar [2900 psi] Nozzle orifice: 0.017-0.023") If brush or roller application is used, more coats will be necessary to achieve the specified dry film thickness. In general, thinning is not recommended. Spray data are indicative and subject to adjustment. Pressure is for a material temperature of 20°C [68°F].
The film thickness is dependent on the required fire resistance as well as the massivity factor (Hp/A) of the steel element. The maximum thickness per coat is 1600 micron [64 mils] Dry Film Thickness equivalent to 2133 micron [85 mils] Wet Film Thickness. Please consult the Application Instruction for more detailed information.
To avoid condensation, apply on a clean and dry surface with a temperature that is at least 3°C [5°F] above the dew point. Stir well before use.
Clean tools with Hempel's Tool Cleaner 99610. Thinning is not recommended.
