Surface Preparation: Before applying VpCI®-388 Water-Based Temporary Coating, it is crucial to ensure that the substrate is thoroughly cleaned and free from any contaminants that could hinder adhesion. Remove dirt, drawing components, grease, oil, fingerprints, rust inhibitors, or other surface impurities.

When applying inhibitors for structural steel, we suggest NACE #3/SSPC-SP6. Before the full-scale application, it is advisable to conduct a test for system adhesion or consult Cortec if you’re unsure what to do.

Note: Before applying the coating, ensure that the condensation point is lower than 5°F or 2°C air temperature. To achieve a uniform and specific consistency, agitate the coating. You can use a drill mixer, a cylindrical type of mixer, or any method that achieve the same results. Apply VpCI®-388 using various methods such as spraying, rolling, brushing, or dipping.
