DIRECTIONS FOR USE

1. 1)  Neutralisation of retained acidic waste

   For every litre of spent pickling waste, add approximately 1.7 litres of S-Weld Neutralizer. The S-Weld Neutraliser on contact with the spent acid waste will go clear. Keep on adding S-Weld Neutraliser solution till a faint pink coloration exist.

   If neutralisation has not occurred with the initial dosage, then add additional quantities of S-Weld Neutraliser at 100ml per litre of waste until colour change is observed.

2. 2)  Diagnostic Use

   After washing the pickling gel away and while still wet, spray the S-Weld Neutraliser solution directly onto the area where the pickling gel was applied, in particular in corners and crevices. If residual acid is present an effervescent reaction will occur. Flush with water thoroughly once the effervescence has stopped.

   Avoid contact with skin or eyes.

SAFETY PRECAUTIONS

S-Weld Neutraliser is an alkaline solution so that contact with skin and eyes is avoided. Wear eye goggles and appropriate protective clothing.

If the product comes in contact with the skin immediately wash affected area thoroughly with water and soap. Seek medical attention in the event of irritation. If required remove and rinse contaminated clothing.
