ASTM D5069-07

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3. Summary of Practice
3.1 Using the paint chosen for the evaluation, the paint-roller cover to be tested is repeatedly and generously loaded with paint
2
and painted out over the same area of approximately 4 square feet (0.4 m ) until it is saturated with paint, that is, the paint-roller
cover cannot pick up any more paint, nor apply any more paint to the area being used for break-in.
4. Significance and Use
4.1 Until a paint-roller cover is saturated with paint, only part of the paint loaded onto the paint-roller cover can be transferred
to a surface being painted. The remainder of the paint is absorbed into the fabric of the paint-roller cover. The amount of paint
absorbed by a paint-roller cover is inversely proportional to the amount already present within the paint-roller cover. By saturating
the paint-roller cover before testing, quantitative inaccuracies of the amount of paint delivered to a surface are eliminated.
4.1.1 Using a saturated paint-roller cover enables the user to apply paint at controllable spreading rates.
4.1.2 Using a saturated paint-roller cover affords reproducibility, when repeating a test.
5. Apparatus
5.1 Paint Tray.
5.2 Paint Roller Frame, of the same size as the paint-roller cover being prepared.
6. Materials
6.1 Paint, to be used in test.
6.2 Primed or Smooth Surface, to be used for the roller-cover break-in.
