The proper use and specification of Rosendale Natural Cement Products® must consider the best practices developed for natural cement technology over the past 193 years. For most cases, the use of a custom prepackaged Rosendale cement mortar, render, grout, concrete or repair compound will be most effective in eliminating potential on-site errors in proportioning and/or aggregate selection.

This section  is dedicated to guide specifications to assist in proper selection, use and quality control of natural cement for various restoration applications. Simply stated, specifications should require the use of natural cement meeting the requirements of ASTM C10. For applications requiring the use of Quick-Setting Natural Cement, specifications should require use of Quick Setting Natural Cement meeting the requirements of ASTM C10.

See a typical certification, as can be required.

The following repointing mortar specification is the first of a series of guide specifications. Additional specifications will be added over the next few months.
