• Site Condition:

  • Ensure all surfaces are free of loose debris and any liquids or moisture.

  • Product arrives “Ready for Use”.

  • DO NOT dilute with water.

  • DO NOT mix with other products.

  • Do not apply product in freezing conditions.
    

• Application Notes:

  • Requires mixing prior to use. Use a plastic or clean, rust-free drill mixer (wash after use).

  • Weld Healer and wash water are fully biodegradable and may be washed away according to Commonwealth, State, or Local Government regulations.

  • Suitable for application by brushing, spraying, or dipping simplifies the restorative process.

  • NEVER use a metal bristle brush.

  • May be applied on vertical, horizontal, and overhead structures.

  • Apply liberally; ensure the surface area to be treated is adequately covered by the Weld Healer product (2mm – 3mm thickness).

  • Once applied, DO NOT agitate or interfere with the product.

  • Leave until the desired result is achieved.

  • Can be left on stainless steel as long as is needed – overnight or until removal is 

    convenient – without fear of pitting, corrosion or thinning of the weld or base metal.
    

• Coverage:

  • 18-24 linear meters per liter.

  • Apply at least a 5 cm wide band of Weld Healer product that liberally covers the underlying weld seam and all discoloration.

• Sprayer Specifications

  • 2 Quart Stainless Steel Pressure Pot Sprayer with regulator of up to 50psi.

  • Recommended 68SS x 68PB Nozzle Setup.
    

• Dwell Time:

  • Normal working dwell time (in temperatures above freezing) is between 90 minutes to 120 minutes.

  • Dwell time will vary slightly based on the amount of chromium oxide, heat tint, and discoloration of the surface.

  • Warmer temperatures increase working speed and decrease dwell time.

  • We recommend testing in a small area to determine precise dwell time.
    

• Product Removal by:

  • Pressure washing

  • Wiping

  • Washing

  • Nylon/plastic scrub brush (never use metal/wire brush as cross-contamination will occur)
    

• Safety Notes:

  • Avoid eye contact. Wear chemical safety glasses with side protection.

  • Avoid skin contact. Use chemical-resistant gloves and clothing.

  • Use in areas with adequate ventilation.

  • DO NOT swallow or ingest.

  • DO NOT eat, drink, or smoke when using this product.

  • Wash exposed areas thoroughly with soap and water.

  • Refer to SDS.
    

• Handling & Disposal:

  • Does not require any special handling.

  • Product itself is biodegradable, however once applied, the product will naturally be contaminated with metal ions so disposal should always be approached with a knowledge of local regulations to ensure compliance with any and all rules for your area.
    

• Storage:

  • Requires no speciality storage or handling.

  • Store in well-sealed containers to prevent spillage and contamination.
