Standards and Guidelines on White or Tinted Alkyd Paint
PAINT SPECIFICATION NO. 104 – White or Tinted Alkyd Paint
1. Scope
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. Description
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.
3. Referenced Standards
3.1 The latest issue, revision, or amendment of the referenced standards in effect on the date of invitation to bid shall govern, unless otherwise specified.
3.2 If there is a conflict between the requirements of any of the cited referenced standards and this specification, the requirements of this specification shall prevail.

6.4 DIRECTIONS FOR USE: The following directions of use shall be supplied with each container of paint:
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. Inspection
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. Disclaimer
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.
