Standard Practice for Evaluating Accelerated Efflorescence of Latex Coatings
|Publication Date:||1 July 2004|
|ICS Code (Paints and varnishes):||87.040|
1.1 This practice covers the evaluation of the degree to which a latex paint resists the formation of efflorescence and alkali burnout on the exposed paint surface.
1.2 This practice is designed primarily to relate efflorescence originating in the substrate to the deposit appearing on the surface of latex paints. This practice relates chiefly to the painting of masonry-type substrates such as concrete block, brick, mortar, stucco, poured concrete and similar materials.
1.3 The values in SI units are to be regarded as the standard. The values in parenthesis are for information only.
1.4 This method does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
