New Test Methods for Floor Patching and Smoothing Compounds Containing Hydraulic Cements

1. Scope

These test methods are appropriate to evaluate the performance of floor patching and smoothing compounds containing hydraulic cements that are used to improve the levelness, smoothness, and flatness of existing floors. These materials may be used as an underlayment to receive floor finishes. The floor patching and smoothing compounds covered by these test methods consist of proprietary blends of hydraulic cements, along with fine aggregate, polymers, fillers, and other additives. This standard does not cover Self-leveling Compounds as defined in ASTM C1708


floor patch compound


Floor patching trowelable compounds have been in use for many years and continue to be used for quick and easy floor leveling as a flooring surface preparation step. This standard is to define a group of test methods suitable to evaluate the performance of these floor patching compounds. As with C1708, specifications for these products can be written to define performance requirements for the different types of floor covering and would be done by a different subcommittee.

The title and scope are in draft form and are under development within this ASTM Committee.
