1.1 This test method covers an accelerated laboratory procedure to determine if a sample of a joint sealant will stain the substrate when in contract with masonry, concrete, or stone (such as marble, limestone, sandstone, and granite). This test method also is intended to determine whether the sealant itself will change in color when exposed to the weather.

1.2 The values stated in SI units are to be regarded as the standard. The value given in parentheses are for information only.

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.


Staining of a building is an aesthetically undesireable occurance. This test method evaluates the likelihood of a sealant causing early stain on a porous substrate due to certain chemical exudations from the sealant.

4.1.1 This test method may not predict staining caused by such factors as residue run-down or dirt pick-up by a sealant exudate.

This test method is useful to predict potential color changes in the sealant itself after weathering.

This test method measures color change in a sealant and staining of substrate by the sealant under conditions of artificial weathering. See also Test Method D 2203, which measures staining by a sealant due to gross exudations from the sealant; it does not subject the sealant to artificial weathering.
