Keystone Masonry Type N

Proportioned and packaged under laboratory-controlled conditions, Lehigh masonry cements take the guesswork out of mortar mixing and ensure consistent results from batch to batch, project to project.Type N is for general use in most mortar and stucco applications.


Masonry cement consists of portland or blended cement, plasticizers, and an air entraining agent. Air-entraining agents protect mortar from freeze-thaw damage and provide additional workability. The specific components of masonry cement may vary depending on the manufacturer and local construction practices. ASTM C91 defines masonry cement by physical requirements and performance properties rather than ingredients.
