Surface Preparation: All surfaces should be clean, dry and free from contamination. The surface should be assessed and treated in accordance with ISO 8504.
Bare steel: Blast cleaning to Sa 21⁄2 (ISO 8501-1:2007). Roughness: using abrasives suitable to achieve grade Fine to Medium G (30-85 μm, Ry5) (ISO 8503-2).
Coated surfaces: Clean, dry and undamaged compatible primer.
Other surfaces: The coating may be used on other substrates.
Please contact us for more information.
Typical Paint Systems: All Intumescent Coatings should be applied over a compatible primer. The Intumescent coating, either 60/120 or 60 WB, then has to be applied to the correct loading which is determined by the steel size. At Elmbridge we can offer to calculate the loading and then quantify the material required for the particular project. Please call for your tailor made specification.
