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.
