ASTM D6083/D6083M-24

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.
Designation: D6083/D6083M − 21 D6083/D6083M − 24
Standard Specification for
Liquid-Applied Acrylic Coating Used in Roofing
This standard is issued under the fixed designation D6083/D6083M; 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 (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This specification covers liquid-applied water-dispersed acrylic latex elastomeric protective roof coatings.
1.2 This specification does not provide guidance for application.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the
two systems may result in nonconformance with the 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, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 For definitions of terms used in this specification, see Terminologies D16 and D1079.
4. Classification
4.1 Type I and Type II are defined by the liquid physical properties in Table 1 and cured film physical properties in Table 2.
5. Materials and Manufacture
5.1 Composition—The product, as manufactured, shall be in liquid form for application to the roof surface by brushing,
squeegeeing, rolling, or spraying. The product shall be composed of a water-based acrylic latex elastomeric emulsion polymer, to
which various pigments and other additives have been added to give the required physical properties.
6. Liquid and Cured Film Physical Properties
6.1 Although the product is supplied as a liquid, its performance is based on the functional properties of the cured material in film
form. The coating is formed into a film adhered to the substrate.
6.2 Liquid Physical Property Requirements—The liquid coating shall comply with the property requirements in Table 1.
6.3 Cured Film Physical Property Requirements—The cured film shall comply with the requirements listed in Table 2.
7. Test Methods
7.1 Specimen Preparation—Prepare coating films by applying two coats, with a minimum of 4 h drying period between coats, to
a suitable release surface so film will not tear upon removal (see Test Method D2370) to give a total dry mil thickness of 0.50 6
0.05 mm [0.02 6 0.002 in.]. The film is allowed to thoroughly cure at 23 6 2 °C [73.4 6 3.6 °F] and 50 6 10 % relative humidity
for 336 6 12 h. The film shall be removed from the release paper and turned over after the first 168 h to allow for complete curing.
7.2 Elongation and Tensile Strength (Test Method D2370):
7.2.1 Test conditions: 23 6 2 °C [73.4 6 3.6 °F] at 50 % 6 10 % RH.
7.2.2 Cut specimen measuring 75 mm [3 in.] long by 13 mm [0.5 in.] 6 10 % wide.
7.2.3 Test Type or Functional Equivalent:
Cross head speed 25 ± 0.5 mm/min [1.0 in./min]
Gage length 25
