CH#060 - The Monadnock Building, Market Street



The Monadnock Building, Market Street
San Francisco, CA






The Challenge:

The painted concrete and plaster exterior of the building was peeling and flaking. The decorative façade at the top of the building was deteriorating due to moisture intrusion.


Benefits Desired:

  • Class A Fire Rating
  • Highly impact and abuse resistant
  • Seal, waterproof and protect the surface
  • To not detract from ornamentation and detail
  • Little or no surface preparation
  • Cost effective and long-lasting



A GLOBAL Encasement Class A Fire Rated LeadLock System was designed using PrepLESS Primer and LeadLock™ TopCoat. The LeadLock System offered all of the desired benefits. It also allowed the contractor to abate the Lead-Based Paint and waterproof the surface with no damage to the plaster.
