    Significance and Use

    This guide provides information that, if implemented, will reduce efflorescence potential in new masonry walls. However, its implementation will not always completely prevent efflorescence.

    This guide may be augmented by related information contained in the appendixes of Specification C270, the additional material listed at the end of this specification, and other publications.

    1. Scope

    1.1 This guide covers methods for reducing efflorescence potential in new masonry walls.

    1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
