About This Item
ASTM C1787 is the ASTM standard specification for the installation of non metallic plaster bases, or lath, used with Portland cement based plaster in vertical wall applications. It provides a focused technical reference for selecting and installing these base materials in wall assemblies where consistent placement and compatibility with plaster are important. For specifiers, contractors, and quality teams, this standard helps define a common basis for installation practices and product evaluation.
Purpose of ASTM C1787
The purpose of ASTM C1787 is to establish a clear specification for installing non metallic plaster bases used with Portland cement based plaster on vertical walls. As a technical document, it supports consistent workmanship by helping define how lath is applied within this type of plaster system. That consistency can be important when comparing products, reviewing project requirements, or checking that installation practices align with the intended wall assembly.
Common use cases of ASTM C1787
This standard is commonly used when non metallic lath is specified for vertical wall plaster systems that rely on Portland cement based plaster. It may be referenced by designers, installers, inspectors, and procurement teams working on wall assemblies where the plaster base is part of the finished system. ASTM C1787 is especially useful during specification writing, submittal review, and field quality checks for plaster base installation.
Why ASTM C1787 matters
ASTM C1787 matters because installation requirements can directly affect the performance and consistency of a plaster wall system. Using a recognized ASTM standard helps reduce ambiguity in procurement and installation expectations, which can support compliance and quality control. It also gives project stakeholders a practical reference for evaluating whether the non metallic plaster base has been installed in a manner appropriate for Portland cement based plaster in vertical wall applications.
