If water -cleaning, use Low Pressure Water -Cleaning (LPWC) in accordance with SSPC -SP 12/NACE 5. Obtain the Engineer’s approval before using soluble salt cleaning aids or additives. Provide at least Class 3W containment to collect water, paint chips, and solids as specified in SSPC Guide 6. Consider waste hazardous until approved TCLP testing indicates otherwise. Testing performed by cotton swab method is unacceptable for dispute resolution.
4.Anchor Profil e Provide access after blast cleaning at locations designated by the Engineer in accordance with Section 105.11, “Inspection of Work” for checking anchor profile heights. If anchor profile heights are not in the range from 1.0 mil to 3.5 mil [25 µmµ to 89 µ] or at least the height that the coating manufacturer’s product data sheet specifies, continue surface preparation until the Engin eer determines that the profiles are the correct heights. Apply primer only after verifying the anchor profile ranges comply with the Contract. Remove dirt, dust, and debris from the surface on the day of cleaning by brushing, blowing with clean dry air, or vacuuming, and apply the first coat of paint. Repeat blast -cleaning if the surfaces rust or become contaminated before painting. Use HEPA -vacuums to clean surfaces of lead paint except when inside containment with operating dust collectors. The Depar tment will allow the use of oil -free compressed air to remove secondary dust not generated by the blasting operation.
b.Existing Steel with Paint to Remain The Engineer will determine the degree of surface corrosion present in accordance with SSPC -VIS 2. Clean and prepare surfaces in accordance with SSPC -SP 1, SSPC -SP 2, SP 3, SP 10 and SP 11, based on the percentage of visible rust. Clean 2 in [50 mm] beyond damaged areas. Feather edges of old paint to make a smooth transition. If using tools, clean in accordance with SSPC -VIS 3. For less than 10 percent visible rust and deteriorated paint, use tool cleaning methods in accordance with SSPC -SP 2 and SP 3 to remove dirt, loose mill scale, loose rust, and loose paint. Clean small areas with pinhole corr osion, stone damage from traffic, or minor scratches. Use the SSPC SP 10 blast -cleaning methods specified in Subsection 512.04.B(1)(a), “New Steel or Existing Steel Stripped of Paint, ” to remove visible mill scale , rust, paint, oxides, corrosion products, and other foreign matter for more than 10 percent visible rust and deteriorated paint.

5.Application of Paints
a.General Mix and apply the paint in accordance with the manufacturer’s Product Data Sheet and this specification whichever is more restrictive. Use mechanical mixers. Take precautions when mixing systems that cure by reacting with air or moisture. Before and during application, mix the paint to blend -in the pigment and vehicle. Use pot agitation for inorganic zinc and zinc -rich organic coatings as the manufacturer specifie s. Continue mixing during paint application. The Department will not allow thinning of paints formulated ready for application. Use tarpaulins, screens, covers, or shields to protect surroundings from paint. Apply paint with a brush, spray, or roller, a s specified by the manufacturer. Prevent build -up, runs, sags, skips, holidays, and thin areas in the paint film. Brush -out runs and sags before drying. Use round, oval -shaped brushes, or flat brushes no wider than 4½ in [115 mm], with enough bristle bod y and length to uniformly spread the paint. Brush out the paint during application. PAINTING 512.04 431 Use airless or conventional spray equipment with traps, filters, or separators to exclude oil and water from the compressed air. Verify compressed air cleanliness in acc ordance with ASTM D 5913. Use rollers only on flat, even surfaces. Use rollers that do not leave a stippled texture. Use sheepskin daubers, bottle brushes, or other approved methods to paint surfaces inaccessible for painting by brush, roller, and spray. When spot -painting, scrape off old paint that lifts after the first application. Repaint the area before the next application. Cure each application of paint. Correct skips, holidays, thin areas, and deficiencies before the next application. Coat new s tructures and replacement steel with the primer before erection. Pressure -wash after erection and before applying the field coats. Use power tools to re -clean surfaces with damaged or deteriorating coating, or exposed, unpainted surfaces. Spot -coat bare steel including Category O paint systems with a primer coat to the Contract required thickness.
b.Application of Zinc -Rich Primers Apply zinc -rich primers by spray methods within 12 hr of completing the surface preparation. On areas inaccessible for sp ray, use a brush or daubers as the manufacturer specifies. Use mechanical mixers. Take precautions if coating systems that cure by reacting with air or moisture. Strain multi component primers through a metal 30 -60 mesh screen or a double layer of cheese cloth while pouring into the spray pot. Alternatively, strain immediately before pouring. Apply the primer with an agitating spray pot unless the manufacturer recommends otherwise. Ensure the agitator or stirring rod reaches within 2 in [50 mm] of the sp ray pot bottom and moves continuously during primer application. Keep the primer well mixed. Use spray equipment with the pot, pump, and atomization pressures needed to produce a coating in accordance with the more restrictive of the coating manufacturer’ s published data sheet or zinc paint in accordance with Section 730, “Paint for Structural Steel.” Provide a hose from the pot to the nozzle no greater than 75 ft [23 m] long if using conventional spray. Spray no more than 15 ft [4.5 m] above or below the pot if applying inorganic zinc. Blast -clean back to soundly bonde d primer and recoat using approved methods to obtain the Contract required coating , if mud -cracking occurs in areas with inorganic zinc primer. Obtain the Enginee r’s approval before using SSPC -SP 11, “Power Tool Cleaning to Bare Metal,” instead of blast -cleaning small areas. Ensure primer coats and intermediate coats are cured and dry before applying additional coats. Clean paint surfaces of dust, dirt, salt, and other deleterious materials before applying any paint. Cure inorganic zinc primer for 48 hr, at a humidity of at least 45 percent, or in accordance with the manufacturer’s published data. Provide continuous misting during the curing process when the humi dity falls below 50 percent. Start the misting operation when the
