Revision Date: January 13, 2010
Updated On: January 21, 2010
Editorial Change:
 
Latex paints are sometimes applied over substrates that contain a high level of water soluble salts that result in efflorescence. This practice evaluates a coating’s vulnerability to efflorescence.

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.

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.
