Directions For Use

1. The surface should be pre-cleaned to remove oils and greases before applying the passivating agent. Use Callington S-Weld Brite Wash.  Any contamination will shorten the life of the passivating gel.

2. Stir the gel to ensure a smooth consistency and apply S-Weld Passivator using the acid-resistant brush provided.

3. Application Times - Refer to TDS for application times

4. Rinse thoroughly with clean potable water, dry surfaces to prevent water staining (smut).  If a neutralizing agent has been used this must be followed by rinsing again with clean potable water and surfaces should be dried to prevent water staining.
