New ASTM standard supports stucco use in construction

A new ASTM International standard supports the use of stucco in the construction industry.

Standard C1860 “provides a way to measure the tensile strength or bond strength of stucco in vertical applications,” says ASTM International member and task group chair Matthew J. Innocenzi, P.E. “The results of this test method, when coupled with sound engineering mechanics and analyses, can be used as a tool to help evaluate the performance of stucco when subject to lateral loads.”

The standard fills an important need for a consensus-based test method for testing stucco, Innocenzi says.
