8. How to use

  • CLEAN ALL JOINT SURFACE - Clean all substrate surface and regarding dust oil, frost and any contaminants Wipe polluted parts using solvent and a piece of cloth. Do not use detergent, soap and water.
  • INSTALL BACK-UP MATERIALS - Backer rod materials such as closed cell polyethylene type can be used as the base of the joint to control sealant depth.
  • MASK ADJACENT SURFACE WITH MASKING TAPE - Masking tape will ensure a clean, neat appearance and reduce clean up by protecting surrounding areas from excess sealant.
  • PRIMING - Primer may be needed for optimum adhesion to some substrate surface.
  • APPLYING SEALANT -Applying sealant deeply into joint. Sealant must be filled into the joint cavity perfectly.
  • TOOL SEALANT - Tool sealant immediately after sealant application. It helps to provide smooth and flat finish and to ensure that the sealant wets the sides of the joint without any voids.
  • REMOVE MASKING TAPE - Remove masking tape prior to forming sealant surface skins.
  • CLEANING - Clean all stuffs around sealant cure area and do not touch when sealant is curing.

 

9. Handling Precautions

  •  Use at room temperature in the range of 30 to 80 % relative humidity.
  • Time for complete cure is depend on the thickness of sealant applied.
  • Adhesion may decline in case of the substrate contaminated. For the best adhesion, clean surfaces thoroughly with solvent before applying the product.
  • Wear eye protection and protective gloves when handling this product.
  • Maintain adequate ventilation in the work place at all times.
  • Keep in place that child’s hand does not touch and never ingest or do not touch in skin
