Preparation as an Anode Shield for New Building or Major Refurbishment
Where necessary, remove weld spatter and smooth weld seams and sharp edges. Abrasive blast clean to Sa2½ (ISO 8501-1:2007). If oxidation has occurred between blasting and application of Intergard 821, the surface should be reblasted to the specified visual standard.

Preparation as an Anode Shield for Repair
Prepare bare areas of steel by blasting to Sa2½ ISO 8501:1. Feather or chip back the surrounding area to a sound edge. Roughen the exposed edge of the existing Intergard 821 to provide a mechanical key. Overlap the Intergard 821 onto this abraded area.

Preparation For Filling Pitting
Blast out to Sa2½ ISO 8501-1:2001. If cleaning cannot be carried out effectively by blasting, mechanically grind out the pits using a suitable carborundum head.
Apply appropriate primer before oxidation occurs. Apply the Intergard 821 within the overcoating interval specified for the primer, (consult relevant primer data sheet).
Ensure that the area is clean and dry prior to application of Intergard 821.
