Standard Test Method for
Leveling of Paints by Draw-Down Method1

This standard is issued under the fixed designation D 4062; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This test method2 covers the laboratory determination of
the relative leveling of water and solvent-reducible architectural paints in white and light tints by comparing the ridges
produced in a draw-down film to a series of plastic leveling
standards.

1.2 Unpigmented, texture, and deep-tint coatings cannot be
readily evaluated with the shadowing produced by oblique
lighting employed in this test method. Such coatings may be
rated by comparing them with the plastic standards at various
angles of reflection. For this purpose ordinary room lighting is
satisfactory.

1.3 Since other factors may influence the tendency of liquid
paints to sag, this test method is not intended to measure
sagging.

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

1.5 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.

2. Terminology

2.1 Definitions of Terms Specific to This Standard:

2.1.1 leveling—of a paint, a measure of its ability to flow
out after application so as to obliterate any surface irregularities such as brush marks, orange peel, peaks, or craters that
have been produced by the mechanical process of application.

3. Summary of Test Method

3.1 The material to be tested is presheared and then applied
to a sealed chart by means of a special leveling test blade
designed to lay down a film with parallel ridges simulating
brush marks. After allowing the completed draw-down to dry
in a horizontal position, leveling of the test paint is rated by
