Application steps

SUBSTRATE PREPARATION

  • Joint surfaces must be clean, dry and free from frost.
  • Remove all dirt, laitance, loose material, mould release and curing agents, and foreign matter.
  • In all joints a bond breaker tape or Sika PEF rod must be used to prevent sealant contact with the back of the joint, to support the sealant, and hence to allow optimum performance.
  • For a neat finish mask the areas adjacent to the joint.
  • On most surfaces sealant adhesion will be improved by the use of a primer.
  • In applications where adhesion is critical (e.g. high movement joints) a primer should be used.
  • For glass, ceramics and mill finished aluminium no priming is required.
  • For timber and other porous surfaces use Sika Primer-3 N.
  • For plastics and other non-porous surfaces, clean using Sika Activator-205.
  • For plastics and other non-porous surfaces that are difficult to bond to gently rub down substrate in single pass with abrasive pad and clean with Sika Activator-205.
  • If in doubt consult Sika or conduct a trial adhesion test.

CLEANING OF TOOLS

Clean tools immediately after use with Sika Thinner C.
