Product Description

Sika Reactivation Primer is a single pack, polyurethane based primer for the reactivation of existing Sika roofing and balcony systems, prior to overcoating. Sika Reactivation Primer is designed to yield excellent adhesion to existing, suitably prepared installations. This enables any localised damage to be easily repaired and facilitates recoating, at the end of the system’s design life, to provide continuing effective protection against water ingress.

Features and Benefits:

  • Allows further coats to be safely applied when the standard re-coating window has been exceeded
  • Single pack
  • Quickly and easily applied
  • May be overcoated from 4 hours (under ideal conditions)
