ASTM D5150-92(1997)e1

Standard Test Method for Hiding Power of Architectural Paints Applied by Roller

SCOPE
1.1 This test method measures the ability of a paint to hide or obscure a surface to which it has been applied by a practical application procedure. This test method covers the use of a paint roller, but the concept is expected to work equally well when the application tool is a paint brush or paint pad.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concernss, 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.

9.4.1 Load the roller cover with paint from the tray by
rolling it through paint so that just the nap is submersed (see
Fig. 2).
9.4.2 Roll out the loaded cover onto a scrap surface, in an
upward and downward motion, within an area no larger than
1-ft (0.3-m) high by the 3-in. (75-mm) width of the roller

9.4.3 Reload the roller cover and roll it out again in the same
manner as 9.4.2 and over the same area. Do not increase the
area except as necessary to control excess dripping of paint.
9.4.4 Repeat the procedure as necessary until the following
conditions are met:
9.4.4.1 Reloading the paint roller cover does not result in
increased paint pickup.
