Application steps

SUBSTRATE PREPARATION

  • Joint surfaces must be clean, dry and free from all dust, laitance, scale, rust, loose particles, grease and foreign matter.
  • Oily surfaces should be degreased with Sika Thinner C.
  • In all joints a bond breaker must be used to prevent sealant contact with the back of the joint, and hence allow optimum performance. In shallow joints self-adhesive polyethylene tape can be used. Deep joints should incorporate a backing strip such as Sika PEF Rod to support the sealant while also acting as a bond breaker.
  • For a neat finish mask the areas adjacent to the joint.

PRIMING: For most common building materials, primers are not required. For advice on adhesion to unusual surfaces, contact Sika's Technical
Department. For copper, lead or brass, and some plastics, priming is required.

CLEANING OF TOOLS

Clean tools immediately after use with Sika Thinner C.
