Standards and Guidelines on White or Tinted Alkyd Paint
PAINT SPECIFICATION NO. 104 – White or Tinted Alkyd Paint
1.1 This speciﬁcation covers a white or tinted low gloss alkyd paint for steel. It has good weathering in rural, industrial, and marine atmospheres. It is also an excellent general purpose paint for use in interior locations.
1.2 This paint is suitable for exposures in Environmental Zones 1A (interior, normally dry) and 1B (exterior, normally dry) and is intended for brush or spray application over rust inhibitive priming paints, over itself, or over other oleoresinous paints. This paint is suitable as an intermediate or topcoat and is to be applied in accordance with SSPC-PA 1, “Shop, Field, and Maintenance Painting of Steel.”
1.3 Four types are available under this speciﬁcation.Type I covers White Paint; Type II covers Medium to Light Gray to Tan Paint; Type III covers Light Green Paint; and Type IV covers a Dark or Forest Green Paint. The shades are variable and are to be agreed upon between the purchaser and the supplier.
2.1 The good weathering ability of this paint is the result of its alkyd vehicle. Details of the composition are given in Table 1.
2.2 This primer contains approximately 48% by volume of nonvolatile ﬁlm-forming solids (pigment and binder). The theoretical spreading rate for a 1.5 mil (38 micrometers) dry ﬁlm thickness is 510 square feet/U.S. gallon (12.6 square meters/liter). Actual spreading rates can be signiﬁcantly lower.

Directions for Use of White or Tinted Alkyd Paint
This paint is intended for use as an intermediate or ﬁnish coat over rust inhibitive primers on structural steel, over itself, or over other oleoresinous paints. All oil, grease, dust, and loose or non-adherent paint shall be removed, as residues of oil and grease remaining on the surface will result in decreased paint performance. If the undercoat is damaged, the steel shall be spot-cleaned and spot-primed with rust inhibitive primer.
Mix paint thoroughly before use. If the pigment has settled, pour off most of the liquid. Thoroughly mix the pigment with the remaining liquid, taking care to scrape all the pigment off the bottom of the can. Gradually add the poured-off liquid and mix thoroughly. Mixing may be made easier by transferring contents to a larger container or by pouring the paint to and from another container. Examine bottom of container for unmixed pigment. Screen paint before applying.
Thin paint only if necessary, using only mineral spirits. For brush application under normal conditions, no thinning should be necessary. For spray applications, add up to one pint of thinner per gallon (120 ml/L) of paint when necessary.
Apply by brush or spray to the speciﬁed ﬁlm thickness or, if none is speciﬁed, to at least 1.5 mils (38 micrometers) dry or approximately 3.0 mils (76 micrometers) wet. The surface to be painted shall be dry; the surface temperature shall be at least 5°F (3°C) above the dew point; and the temperature of the air shall be over 40°F (4°C). Do not paint outdoors in rainy weather or if freezing temperatures are expected before the paint dries.
Allow paint at least 18 hours drying time in good weather before recoating.
7.1 All materials (coatings) supplied under this speciﬁcation are subject to timely inspection by the purchaser or his authorized representative. The purchaser shall have the right to reject any materials supplied which are found to be defective under this speciﬁcation. (See Note 9.1.) In case of dispute, unless otherwise speciﬁed, the arbitration or settlement procedure established in the procurement documents shall be followed. If no arbitration or settlement procedure is established, then a procedure mutually agreeable to the purchaser and material supplier shall be used.
7.2 Samples of paints may be requested by the purchaser and shall be supplied upon request along with the manufacturerʼs name and identiﬁcation for the materials. Samples may be requested at the time the purchase order is placed or may be taken from unopened containers at the job site.
7.3 Unless otherwise speciﬁed, the sampling shall be in accordance with ASTM D 3925.
8.1 While every precaution is taken to ensure that all information furnished in SSPC standards and speciﬁcations is as accurate, complete, and useful as possible, SSPC cannot assume responsibility nor incur any obligation resulting from the use of any materials, coatings, or methods speciﬁed herein, or of the speciﬁcation or standard itself.
8.2This speciﬁcation does not attempt to address problems concerning safety associated with its use. The user of this alkyd paint speciﬁcation, as well as the user of all products or practices described herein, is responsible for instituting appropriate health and safety practices and for ensuring compliance with all governmental regulations.
Notes are not requirements of this speciﬁcation.
9.1 The procurement documents should establish the responsibility for samples, testing, and any required afﬁdavit certifying full compliance with the alkyd paint speciﬁcation.
9.2 ASTM and Federal Standard Test Methods listed as “canceled” or “withdrawn” are no longer maintained, but are still available as historical documents.
