When this system may fit

Is this the right assembly?

  • A façade shows water intrusion or fine cracking
  • Concrete, stucco or masonry needs weather protection
  • A unified, refreshed appearance is desired
  • Joints and penetrations need sealing as part of the work

These are indicators, not a specification. Suitability is confirmed by a project review.
