1.2 This painting system is intended as a one-coat shop paint for open web and long span steel joists that may be either enclosed or exposed in the interiors of buildings (Environmental Zone 1A, interior, normally dry) where the temperature rarely falls below the dew point, where the humidity rarely exceeds 85 percent, and where corrosion protection is not necessary.
2.1 This painting system consists of surface preparation by solvent cleaning and one coat of primer.

7.1 All work and materials supplied under this speciﬁcation are subject to timely inspection by the purchaser or his authorized representative. The contractor shall correct such work or replace such material as is found 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 purchaser, material supplier, and contractor shall be used.
7.2 Samples of paints under this painting system 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.

9.1 The procurement documents should establish the responsibility for samples, testing, and any required afﬁdavit certifying full compliance with the speciﬁcation.
9.2 TOPCOATING: Oil/alkyd type coatings of this system can usually be topcoated without difﬁculty and are compatible with the ﬁnish paints listed in SSPC-PS Guide 1.00, “Guide for Selecting Oil Base Painting Systems.” Asphalt coatings will bleed through most paints. If topcoating is anticipated for aesthetic purposes, it is recommended that the appropriate generic type of shop paint be speciﬁed.
9.3 This painting system speciﬁcation was jointly developed by the Steel Joist Institute and SSPC in cooperation with the American Institute of Steel Construction.
