Application

Instructions

  • Application: :
    • Recommended application temperatures: +5° - +40°C.
    • Apply appropriate primer to joint sides and observe waiting time.
    • In order to guarantee free movement of sealant in joints ,it is imperative that these alant does not adhere to the bottom of the joint, therefore joint backer rod or bond breaker tape should be used at the proper depth. Mix the base and the curing agent.
    •CX JOINT SEALANT PS can be poured directly from the can in to the joint or can be poured in to a barrel applicator and extruded into the joint from the applicator.
    • Pour or firmly extrude sealant into the joint making sure that it is in full contact with the sides of the joint and with the backing rod at the bottom. Light tooling is recommended to ensure no air is trapped in the sealant. For trafficked joints a recessed joint is recommended.
  • Surface preparation : • Joint surfaces must be dry, clean and free of all contamination. Precast panels using form-release agents other than polyethylene film must be sandblasted or mechanically abraded and dust free
  • Product:
    COLOUR : GREY
  • Priming:
    • CX JOINT SEALANT PS: requires CX JOINT SEALANT PS Porous Primer for substrates such as brick, concrete, natural stone, stained timber frames, unglazed tile edges. For non-porous surfaces CX JOINT SEALANT PS Non-Porous Primer is required for substrates such as stainless steel, glass, glazed tile.
    • Due to the number of unpredictable natures of these substrates, a preliminary test is recommended. It is recommended to seek advice for primer requirements for specific applications.
  • Joint Size Suitability:
    • JointWidth : Minimum 6mm, Maximum 25mm (single application), 50mm(multipleapplications) • JointDepth : Minimum 12mm in porous substrates, Minimum 12mm in non-porous substrates • Width : Depth Ratio : 2:1 for butt Joints, 1:1 for lap/floor joints (Within the above min/max restrictions)
