| -- The recoat interval depends on the subsequent exposure conditions | If the maximum recoat interval is exceeded, abrade the primer surface to ensure intercoat adhesion. Surfaces exposed to a contaminated environment must be washed clean with high-pressure fresh water and allowed to dry before recoating. |

When this product is used as a primer in direct contact with the substrate, the surface to be coated shall be clean, dry and free from contamination. Abrasive blast cleaning of the substrate is recommended before painting, to a cleanliness of Sa2½ and a surface roughness of 40–75 µm; oil, grease and weld spatter shall be removed and welds and sharp edges ground before blast cleaning.
Areas that cannot be blast-cleaned shall be power-tool cleaned to St3, removing loose mill scale, rust and dust; before spraying, the surface shall be free of oil and water.
Where old coatings exist (chemically curing coatings only), the old film shall be abraded, loose paint removed by power tool, and other loose impurities removed; the surface shall be free of oil and water.
