Do not apply additional or subsequent coats of paint without the Project Manager’s approval.
C.Application. Apply paint in accordance with Subsection 612.02 Apply paint by brush or spray following the paint manufacturer’s recommendations to produce a uniform coat to the metal or previous paint coat. If using brush painting, thoroughly coat surface irregularities and brush out and smooth to produce an even paint film thickness. Use spray pressure tanks with an agitator to thoroughly stir the paint. If surfaces are inaccessible or have limited access to paint brushes, paint with sprayers or daubers made for that purpose. Limited Access is defined as a location where the physical characteristics or configuration of the structure restricts the use of a surface preparation or paint application tool at that location. A location is not considered Limited Access if additional time will allow for the proper cleaning or painting of the area, or if commercially available tools are available to clean or paint the area (e.g., angle nozzles, or short nozzles in place of traditional long nozzles for blast cleaning). Keep newly painted surfaces protected from environmental conditions that could damage the applied coating until the paint has dried or weather permits removal of cover as required by the coating manufacturer.
1.Shop Paint. Apply a shop coat to all metal surfaces unless otherwise specified. Do not paint surfaces in contact with other metal surfaces or concrete, except as noted in Subsection 612.03.6(A) . This includes faying surfaces and contact surfaces of nuts, bolts, and washers for bolted connections. Apply shop coat immediately after fabrication, shop inspection, and shop cleaning are complete, and the work is accepted. Do not load materials for shipment until paint is dried per the coating manufacturer’s recommendations. Do not apply field coats in the fabrication shop except by written approval of the Project Manager. Use erection marks for field identification of members on painted surface. Use paint for marking that is compatible with the shop coat and the first field coat. Cover erection marks, fabricator’s name, and other identification with subsequent coats.
2.Spot Painting. Field clean masonry and sole plates, bottom of expansion devices and all parts of steel inaccessible for painting after erection as noted above. Spot coat and apply all field coats before erection. Paint on site and allow drying thoroughly before assembling. Handle painted material carefully to prevent damage. Repair and repaint damaged surfaces at no cost to the State. Apply the spot coat after erection and field cleaning is approved by the Project Manager, to the edges of plates, rolled shapes and to the heads of bolts and nuts and areas where the shop coat has been damaged. Where the shop coat is damaged, the Project Manager may require a substantially complete reconditioning or replacement of the shop coat. This painting is considered spot painting and is done at no cost to the Department. Reseal small cracks and cavities not sealed by the first field coat with a zinc paste before the second field coat is applied. Submit documentation from the paint manufacturer that indicates the zinc paste proposed for use is approved by the manufacturer to the Project Manager. 2020 EDITION V5.1 STRUCTURE FINISHES – 612 612-7
3.Stripe Coat Requirements. Stripe coat the primer and second (Intermediate) coat. Striping of the primer coat is permitted after the full application of the primer coat is completed and recoat times are met. Tint both stripe coats in accordance with the manufacturer’s recommendation. Apply the stripe coat for both the primer and second coat using a brush, dauber, or roller to all edges, corners, lattice, angles, rivets, bolts, nuts, washers, welds, sharp and or thin edges. Do not thin paint without written approval.
D.Paint Storage and Mixing. Store paints and thinners in well -ventilated areas that are not subject to excessive heat, open flames, electrical discharge, and direct rays of the sun. Adhere to the manufacturer’s recommendations. Store materials in heated areas when necessary. Use materials on a rotating stock basis, and leave containers closed until used. Do not use paints that cannot be stirred to normal consistency. Store paint in tightly covered containers at an ambient temperature of at least 45 °F. Maintain containers in a clean condition, free of foreign materials and residue. Remove and discard thin skins formed in the container. Do not use material that is livered, gelled, thick skinned, or otherwise questionable. Mix paints per manufacturer’s instructions and as approved. Do not thin the paint unless authorized by the paint manufacturer and approved. The Inspector must be present whenever the paint is thinned. Do not use materials that are beyond their pot life or shelf life. For multiple component paints, only complete kits can be mixed and used. Partial kit mixing is prohibited. Remove waste chemical solutions, oily rags, and other waste daily. Take precautionary measures to ensure protection of workers and work areas from fire hazards and health hazards resulting from handling, mixing, and applying materials.
