PAINT SYSTEM SUBSTRATE METHOD OF CLEANING C, D, I & J Abrasive blast cleaned steel Existing Paint to be Removed - Localized (a) and (b) and complete (h) E & H Overcoating existing paint Existing Paint to be Overcoated - Localized (a) and complete (c) followed by (d) and (e)

436.03.11 Test Plates/Sections. When abrasive blast cleaning is specified, furnish two

12 in. x 12 in. x 1/4 in. steel test plates and clean them to meet SSPC VIS Standards and the Contract Documents. Apply a clear protective coating to these standard test plates and use them as a job sample standard for cleaning operations. When approved as an alternative to the test plates, portions of an actual work piece may be used in order to reach agreement on the degree of cleaning before production surface preparation begins. When the SSPC VIS Standards accurately depict the agreed upon degree of cleaning on the test section, the prepared section does not have to be sealed and retained for future reference. When the SSPC VIS Standards do not accurately depict the degree of cleaning, the test section shall be sealed and retained, or the test plates utilized. For the production cleaning operations, the written requirements of this Specification, the SSPC definitions, the test plates, and the SSPC VIS Standards shall be used in that order for determining compliance with the Contractual requirements.

436.03.12 Removal of Vegetation, Planking, Signage, and Cleaning of Drainage Troughs.

Prior to surface preparation, remove vegetation overhanging or fouling the structure and remove any accumulations of debris from inside the drainage troughs. When the structure has planking (timber or plywood) between the beams, carefully remove it in the areas of work operations. Existing planking that is in good condition may be used in the proposed planking operations. Store and maintain in good condition the existing planking that is to be reused. Dispose of all debris on the planking and any planking that is not to be reused. Unless otherwise directed, install the proposed planking after the cleaning and painting operations are complete. The Engineer may direct that the existing planking be reinstalled, or the proposed planking be installed before opening lanes to traffic during that same working day. The Engineer may also request that planking be installed or reinstalled during periods of work stoppage. Reinstall the existing planking or install new planking in the same locations as the existing by following the details in the Contract Documents. Cut any existing planking to fit the details as necessary. Add any missing elements (additional plywood, timber beams, etc.) or replace poor elements with new timber as specified in 921.05. When the fascia webs of the structure contain street identification signs, remove them prior to starting cleaning operations in the area. Clean and paint areas exposed by the sign removal, including bolt holes. Whenever a sign is removed, notify the Engineer. The Engineer will notify the Office of Traffic and Safety’s Chief, Traffic Operations Division. Street signs may be reinstalled by the Office of Traffic and Safety utilizing the Contractor’s maintenance of traffic. They will coordinate this work with the Contractor. If drainage troughs are present, conduct a survey of the troughs prior to construction and document the condition of all trough materials. Notify the Engineer of the locations where trough materials are in poor condition. Clean all drainage troughs on the structure unless otherwise directed by the Engineer. Replace drainage troughs as directed by the Engineer. Support the weight of the trough material to prevent tearing during removal. Remove any hardware used to attach the trough to the structure (e.g.- nuts, bolts, brackets, and fittings). Store and maintain the hardware so that it may be reused when reinstalling the troughs. Remove and properly dispose of any accumulations of debris from inside the trough. Upon completion of cleaning, re-attach the trough material in the same manner it was removed. Overlapping pieces of trough material must maintain the same pattern of overlap as when they were removed. Regardless of whether troughs are removed, 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS replaced, or cleaned, ensure that no paint related debris is present within the troughs at the completion of painting operations.

436.03.13 Repair of Surface Imperfections. Regardless of the method of cleaning, remove

surface imperfections such as sharp fins and slivers, rust scale, weld spatter, and pack rust by a combination of cleaning procedures such as using hand or power impact tools (chipping hammers or scaling hammers), blast cleaning, etc., without scarring good steel.

436.03.14 Feathering and Removal of Defects in Existing Coating. For projects involving the

touch up or overcoating of newly installed steel or existing coatings in the field, regardless of the method used for cleaning, feather the edges of old paint permitted to remain. Remove portions of paint on previously painted surfaces that are chalky, powdered, cracked, or otherwise unacceptable. Remove runs and sags in the existing paint on the outside facing surfaces of fascia beams over highways. Ensure a smooth appearance after application of the new coating.

436.03.15 Surface Condition Prior to Painting. Remove residual dust, dirt, and grease from the

surface as the final procedure prior to painting and between coats whenever the coating is contaminated. Cleaning includes the removal of all dust, puddles, grease, oil, exhaust from trucks, debris, concrete spatter, and other foreign matter on the surfaces being painted. Also remove debris on surfaces adjacent to those being painted. Concrete spatter stains that discolor the primer need not be removed provided material is not dislodged when wiping the surface with a cloth. Cleaning involves vacuuming, solvent cleaning, hand/power tool cleaning, and pressure washing as appropriate. Should an area of previously cleaned steel become soiled, contaminated, or rusted, reclean the area prior to painting at no additional cost to the Administration. Prior to the application of paint in the shop and field, the QC personnel shall inspect the surfaces and establish that they have been prepared according to the Specifications. Upon QC acceptance, obtain approval that the surfaces to be painted during that day have been cleaned as specified. Move all hooks, cables, beam clamps, and outriggers during cleaning operation to allow the underlying surfaces to be cleaned. Any containment attachments that cannot be moved during cleaning and painting must be power tool cleaned to SP-11 Bare Metal and coated using Paint System H.

436.03.16 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. 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS Mix paints according to manufacturer’s instructions and as approved. Do not thin the paint unless authorized by the paint manufacturer and approved. The Engineer shall 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 shall 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.

436.03.17 Paint Representative. The representative shall be a technical representative of the

paint manufacturer. During initial execution of the work the Engineer may require the paint representative to be on site to approve with the Engineer the degree of cleanliness prior to painting and the method of application of the coating system. The Engineer may stop paint operations for failure to meet this requirement regardless of the reason for failure. Areas cleaned prior to ceasing paint operations shall be recleaned if required.

436.03.18 Field Painting. Meet SSPC-PA 1 for painting application and 436.03.19 through

436.03.22 436.03.19 Weather Requirements for Painting. All surfaces to be painted shall be sound and

cleaned as specified. Painting is allowed when:

specified degree of preparation prior to the application of the paint system. Apply all paint according to the manufacturer’s recommendations except the dry film thickness shall conform to 912.05. Spray painting will be permitted provided the Engineer approves the location and method of spray application. Paint all areas adjacent to machinery and mechanical components, etc., by brush application unless the Engineer approves spray application. Surfaces inaccessible for painting by regular means shall be painted using sheepskin daubers or by other means as necessary to ensure coverage of the proper coating thickness. Move hooks, cables, beam clamps, and outriggers whenever possible to allow cleaning and application of all three coats of paint to these areas. Maintain, calibrate, and adjust the thickness measuring instrument, and take measurements according to SSPC-PA 2. Apply stripe coats using brush, dauber, or roller to all edges, outside 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS corners, crevices, welds, rivets, bolts, nuts, and washers prior to application of coatings according to the following schedule: SYSTEM COAT B II & III C I* & II E I & II H II & III I I* & II *Striping of Coat I is permitted after the application of Coat I if the stripe coat is tinted according to manufacturer’s recommendation. Ensure that each coat is free of shadow-through, skips, misses, and thin or heavy coating thickness. Repair defects prior to application of the next coat. Keep the surface to be coated dust-free during painting operations, and protect newly coated surfaces from the cleaning operations. When a previously cleaned or painted area becomes soiled, contaminated, or rusted, reclean the area to the specified condition and completely recoat at no additional cost to the Administration. Apply each coat within 30 days after the prior coat, unless approved in writing by the paint manufacturer. If the recoat window is exceeded, reclean the surface as approved by the paint manufacturer and the Engineer. At project completion, all fascia beams shall have a smooth and uniform appearance throughout. Should any fascia have runs, sags, heavy film build, blisters, bubbles, orange peel or any other coating defect which does not give the appearance of a smooth uniform surface, reclean and paint specific areas or the entire fascia as directed by the Engineer.

436.03.22 Control of Overspray and Spills. Protect the environment from paint droplets,

overspray, and spills by providing containment for the paint application area. Assume responsibility for any damage resulting from wind and cleaning and painting operations. Up to 2 in. of overspray will be permitted onto the adjacent surface of the bridge deck next to the top flange. No other overspray will be permitted. Whenever the method of protection fails to function at the required level of efficiency, immediately suspend all operations except those associated with minimizing adverse impact to the environment. Do not resume operations until modifications have been made to correct the cause of the failure. Use fire retardant containment screens, curtains, and tarpaulins. Paint operations may be stopped by the Engineer due to wind. However, operations shall stop if the wind velocity exceeds 20 mph, unless specific and approved precautions are taken to prevent the escape of paint droplets and overspray.

436.03.23 Caulking. Caulk the following areas with a material approved by the paint

manufacturer. Install caulking between the intermediate and finish coats: 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS

436.03.24 Defective Work. Neither conditions during application nor Laboratory acceptance of

paint shall remove the responsibility of obtaining a satisfactory paint system. When rusting occurs or a paint coat lifts, blisters, wrinkles, or shows evidence of having been applied under unfavorable conditions, the workmanship is poor, impure or unauthorized paint has been used, or for any other reason the painting is unsatisfactory, remove the affected paint and thoroughly clean the steel and repaint. Ensure that there is a uniform appearance throughout the structure.
