    Significance and Use

    Surfactant staining is a common problem with exterior house paints, particularly when subjected to humid environments (such as morning dew) shortly after application.

    Interior paints used in humid areas such as kitchens and bathrooms may also experience surfactant staining.

    Leaching of water-soluble materials may be dependent on colorant dispersions that are mixed into tint base paints. Other paint components may also affect the leaching of water-soluble materials.

    1. Scope

    1.1 This practice covers the ability of a latex paint film to resist staining caused by the leaching of water-soluble materials when contacted with water shortly after application.

    1.2 Water staining is attributed to the leaching of surfactants or other water-soluble materials from a paint film.

    1.3 The values stated in SI units are to be regarded as standard.

    1.4 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 to determine the applicability of regulatory limitations prior to use.
