How to use this product

  • Clean surface free of grease, dirt and dust. For best results roughen bond area prior to cleaning
  • Cut off required amount. Replace disc on remaining portion. Use gloves to avoid messing hands. To mix, knead with fingers to uniform colour. If mixing is difficult, warm to room temperature. Apply with pressure to surface to be repaired (within 2 minutes of mixing) and mould to shape if required. If material sticks to fingers, use the plastic wrapper to press the material in place.
  • For a smooth appearance, remove excess and hand rub with water or a damp cloth before hardening begins.
  • Trim away any excess before initial hardening. Remove any residues with acetone prior to initial hardening. Hardened excess may be sanded or trimmed away once fully cured.
  • After 5-10 minutes Knead-It Steel will harden and begin to form a strong bond.
  • After 60 minutes Knead-It Steel may be drilled, sanded, machined, filed, sawed or painted.
  • Wash hands thoroughly with soap and water after use.

Handy tips

  • Ensure the putty and hardener are mixed properly. Knead-It will become warm as it is mixed, A good indication its mixed properly is when you have a uniform colour, and feel a mild heat radiating from thre knead-it.
  • To help determine when your knead it has set, keep a small piece off to check- when it is hard, it indicates your job is done.
  • Store in a cool place for maximum shelf life
  • Use Knead-It Multi Purpous for applications in contact with drinking water.
  • Use Knead-It Aqua for applications in wet/submerged areas.
  • For cleaning surfaces prior to application of adhesive, if the surface is porous, we would recommend using SELLEYS Liquid Sugar Soap. If the surface is non-porous eg glass or metal, firstly clean the surface with mineral turpentine and then again with methylated spirits. If there is old, difficult to remove residue such as old paint, we recommend using paint stripper such as SELLEYS Kwik Strip Smart. Ensure the surface is dry before applying the product.
  • Keep a canister of SELLEYS Sugar Soap Wipes nearby for a quick and effective cleanup.

Safety tips

  • Where possible wear protective gloves when using Knead-It Steel. Contact with skin may result in irritation. Epoxy resin is a known skin sensitiser. Repeated or prolonged skin contact may lead to allergic contact dermatitis.
  • If redness or swelling of skin occurs, wash thoroughly with soap and water. Seek medical attention if in any doubt.
  • Mixed and cured material is not hazardous. Cured material can only be removed by cutting and abrasion. If cured on skin, it will peel off in a few days without assistance. Soaking in warm water will assist removal.
  • On burning may emit toxic fumes

Storage and re-use

  • Replace siliver disc to seal ends and keep in a cool dry place.
