2.4 ABRASIVE

The referenced abrasive specifications have maximum limits for soluble salts contamination, however, this maximum level of contamination does not guarantee that contamination will not be transferred to the steel surface during abrasive blasting. Other factors such as on-site handling and recycling can allow contamination of abrasive. Contractors are cautioned to verify that the chosen abrasive, along with work and storage processes, allow the final surface cleanliness requirements to be achieved. Successful testing of chlorides in abrasive does not negate the final acceptance testing of steel surfaces.

2.4.1 Non-metallic Abrasive

Section 09 97 13 Page 12

Conform to SSPC AB 1, Class A except that:

a. The gross gamma radioactivity must not exceed 5 picocuries per gram.

b. The maximum allowable chloride content is 7 parts per million (ppm) as measured with the test kit described in the paragraph TEST KIT FOR

MEASURING CHLORIDES IN ABRASIVES. Modify the requirements of SSPC AB

2to substitute requirement for one chloride test for each "WATER

SOLUBLE CONTAMINANTS" test required.

c. The maximum allowable Chromium and Cadmium content of the work mix must be less than 0.1 percent by wt. when tested in accordance with ASTM

D3718 for Chromium and ASTM D3335 for Cadmium. Modify the requirements of SSPC AB 2 to add requirement for one Chromate test and one Cadmium test for each "LEAD" test required.

Use abrasive that is specifically selected and graded to provide a sharp, angular profile to the specified depth. Do not use ungraded abrasive. Make adjustments to processes or abrasive gradation to achieve specified surface profile. Recycled non-metallic abrasive must meet all requirements of the specification each time that it is placed in the blast pot.

2.4.2 Metallic Abrasive

2.4.2.1 New and Remanufactured Steel Grit

Conform to the chemical and physical properties of SSPC AB 3 Class 1 (Steel) only. Class 2 (Iron) abrasive must not be used.

To develop a suitable work mix from new steel abrasive, a minimum of 200 -

400 recycles is required, therefore, it is advantageous for a Contractor to use remanufactured steel grit or grit reclaimed from a previous project.

Such grit must be considered to conform if it can be traced to new grit conforming to SSPC AB 3 Class 1 and it meets all cleanliness requirements of

SSPC AB 3 Class 1 when brought to the current jobsite. Submit one representative sample of this work mix to the laboratory for testing, along with samples of new material. Acceptance and use of this work mix must not be used to justify any deviation from surface preparation requirements.

2.4.2.2 Recycled Steel Grit

Abrasive media must conform to the chemical and physical properties of SSPC

AB 2 except that:

a. The maximum allowable chloride content is 7 parts per million (ppm) as measured with the test kit described in the paragraph TEST KIT FOR

MEASURING CHLORIDES IN ABRASIVES. Modify the requirements of SSPC AB

2to substitute requirement for one chloride test for each "WATER

SOLUBLE CONTAMINANTS" test required.

b. The maximum allowable Chromium and Cadmium content of the work mix must be 0.1 percent by wt. when tested in accordance with ASTM D3718 for

Chromium and ASTM D3335 for Cadmium. Modify the requirements of SSPC

AB 2 to add requirement for one Chromate test and one Cadmium test for each "LEAD" test required.

Section 09 97 13 Page 13

PART 3 EXECUTION

Perform all work, rework, and repair in accordance with approved procedures in the Coating Work Plan.

3.1 SURFACES TO BE COATED

Coat exterior surfaces of guide piles from 2’ above low water to the top as indicated on the plans.

3.2 LIGHTING

Provide lighting for all work areas as prescribed in SSPC Guide 12.

3.3 ENVIRONMENTAL CONDITIONS

3.3.1 Containment

Design and provide a containment system for the capture, containment, collection, storage and disposal of the waste materials generated by the work under this Section, to meet the requirements of SSPC Guide 6, Class 3.

Vapor concentrations must be kept at or below 10 percent of Lower Explosive

Limit (LEL) at all times. Containment may be designed as fixed containment for complete structure or portable containment for sections of structure, however, containment must remain in any one place from beginning of abrasive blasting through initial cure of coating. Collection and disposal of waste materials shall be in compliance with all federal, state and local regulations. See Appendix B for limited paint chip analysis.

It is the Contractors responsibility to insure the feasibility and workability of the containment system. The Contractor must perform his operations and work schedule in a manner as to minimize leakage of the containment system. The containment system must be properly maintained and must not deviate from the approved drawings. If the containment system fails to function satisfactorily, the Contractor must suspend all operations, except those required to minimize adverse impact on the environment or government property. Operations must not resume until modifications have been made to correct the cause of the failure.

3.3.2 Automated Monitoring Requirements, Field and Shop Applications

Provide continuous monitoring of temperature, relative humidity, and dew point data at pertinent points on the structure, during surface preparation, coating application, and initial cure. Locate sensors to provide pertinent data for the surface preparation and coat application being performed.

Monitor any heating, cooling, or dehumidification equipment used. Make data available to the Contracting Officer through Internet access. Provide monitoring equipment to perform as follows:

a. Data is collected in the field unit in one minute increments, and available for download or viewing (on-site) in a standard format.

Contractor must collect this data and make available to the Contracting

Officer;

b. Monitoring equipment must have backup power such that data collection and transmission to web server will be uninterrupted during the entire period of the dehumidification requirement;

Section 09 97 13 Page 14

c. Monitoring equipment must have capability to measure surface temperatures at a minimum of four locations;

d. Monitoring equipment must have capability to measure dry bulb temperature (DB), relative humidity (RH), and dewpoint temperature

(DP);

3.4 SURFACE PREPARATION

3.4.1 Abrasive Blasting Equipment

Use abrasive blasting equipment of conventional air, force-feed, or pressure type. Maintain a minimum pressure of 95 psig at nozzle. Confirm that air supply for abrasive blasting is free of oil and moisture when tested in accordance with ASTM D4285. Test air quality at each startup, but in no case less often than every five operating hours.

3.4.2 Operational Evaluation of Abrasive

Test abrasive for salt contamination and oil contamination as required by the appropriate abrasive specification daily at startup and every five operating hours thereafter.

3.4.3 Surface Standard

Inspect surfaces to be coated, and select plate with similar properties and surface characteristics for use as a surface standard. Blast clean one or more 1 foot square steel panels as specified in paragraph SURFACE

PREPARATION. Record blast nozzle type and size, air pressure at nozzle and compressor, distance of nozzle from panel, and angle of blast to establish procedures for blast cleaning. Measure surface profile in accordance with

SSPC PA 17 using Rmax as the measure of profile height. When the surface standard complies with all specified requirements, seal with a clearcoat protectant. Use the surface standard for comparison to abrasive blasted surfaces throughout the course of work.

3.4.4 Pre-Preparation Testing for Surface Contamination

Perform testing, abrasive blasting, and testing in the prescribed order.

3.4.4.1 Pre-Preparation Testing for Oil and Grease Contamination

Inspect all surfaces for oil and grease contamination using two or more of the following inspection techniques: 1) Visual inspection, 2) WATER BREAK

TEST, 3) CLOTH RUB TEST. Reject oil or grease contaminated surfaces, clean using a water based pH neutral degreaser in accordance with SSPC SP 1, and recheck for contamination until surfaces are free of oil and grease.

WATER BREAK TEST - Spray atomized mist of distilled water onto surface, and observe for water beading. If water "wets" surface rather than beading up, surface can be considered free of oil or grease contamination. Beading of water (water forms droplets) is evidence of oil or grease contamination.

CLOTH RUB TEST - Rub a clean, white, lint free, cotton cloth onto surface and observe for discoloration. To confirm oil or grease contamination in lightly stained areas, a non-staining solvent may be used to aid in oil or

Section 09 97 13 Page 15 grease extraction. Any visible discoloration is evidence of oil or grease contamination.

3.4.4.2 Pre-Preparation Testing for Soluble Salts Contamination

Test surfaces for soluble salts, and wash as required, prior to abrasive blasting. Soluble salt testing is also required in paragraph PRE-

APPLICATION TESTING FOR SOLUBLE SALTS CONTAMINATION as a final acceptance test of prepared surfaces after abrasive blasting, and successful completion of this phase does not negate that requirement. This phase is recommended since pre-preparation testing and washing are generally more advantageous than attempting to remove soluble salt contamination after abrasive blasting. Effective removal of soluble salts will require removal of any barrier to the steel surface, including rust. This procedure may necessitate combinations of wet abrasive blasting, high pressure water rinsing, and cleaning using a solution of water washing and soluble salts remover. The soluble salts remover must be acidic, biodegradable, nontoxic, noncorrosive, and after application, will not interfere with primer adhesion. Delays between testing and preparation, or testing and coating application, may allow for the formation of new contamination. Use potable water, or potable water modified with soluble salt remover, for all washing or wet abrasive blasting. Test methods and equipment used in this phase are selected at the Contractor's discretion.

3.4.5 Water Jetting and Abrasive Blasting

On previously coated and prepared surfaces Waterjet all steel surfaces to a

NACE WJ-1, NV-3 condition employing Ultrahigh-Pressure Waterjetting (UHP WJ) at more than 30,000 psi. If mutually agreed upon by the government and contractor at the pre-application meeting, waterjetting must be followed by abrasive blasting the steel surfaces to near-white metal in accordance with

SSPC SP 10/NACE No. 2. Provide a 1 to 2 mil surface profile. Reject profile greater than 5 mils, discontinue abrasive blasting, and modify processes and materials to provide the specified profile. Prepared surfaces must conform to SSPC VIS 1 and must match the prepared test-panels. Measure surface profile in accordance with SSPC PA 17, using Rmax as the measure of profile height.

3.4.6 Disposal of Used Abrasive

Dispose of used abrasive off Government property in accordance with Federal, State, and Local mandated regulations.

3.4.7 Pre-Application Testing For Surface Contamination

3.4.7.1 Pre-Application Testing for Oil and Grease Contamination

Ensure surfaces are free of contamination as described in paragraph PRE-

PREPARATION TESTING FOR OIL AND GREASE CONTAMINATION, except that only questionable areas need be checked for beading of water misted onto surface.

3.4.7.2 Pre-Application Testing for Soluble Salts Contamination

Test surfaces for chloride contamination using the Test Kit described in

TEST KIT FOR MEASURING CHLORIDE, SULFATE AND NITRATE IONS ON STEEL AND

COATED SURFACES. Test all surfaces at rate of three tests for the first 1000 square feet plus one test for each additional 2000 square feet or part thereof. Concentrate testing of bare steel at areas of coating failure to bare steel and areas of corrosion pitting. One or more readings greater than 3 micrograms per square centimeter of chlorides or 10 micrograms per square centimeter of sulfates or 5 micrograms per square centimeter of nitrates is evidence of soluble salt contamination. Reject contaminated surfaces, wash as discussed in paragraph PRE-PREPARATION TESTING FOR SOLUBLE

SALTS CONTAMINATION, allow to dry, and re-test until all required tests show allowable results. Reblast tested and cleaned areas as required. Label all test tubes and retain for test verification.

3.4.7.3 Pre-Application Testing for Surface Cleanliness

Apply coatings to dust free surfaces. To test surfaces, apply strip of clear adhesive tape to surface and rub onto surface with finger. When removed, the tape should show little or no dust, blast abrasive, or other contaminant. Reject contaminated surfaces and retest. Test surfaces at rate of three tests for the first 1000 square feet plus one test for each additional 1000 square feet or part thereof. Provide two additional tests for each failed test or questionable test. Attach test tapes to Daily

Inspection Reports.

3.5 MIXING AND APPLICATION OF SEALANT AND COATING SYSTEM

3.5.1 Preparation of Coating Materials for Application

3.5.1.1 Mixing Materials

Mix in accordance with manufacturer's instructions, which may differ for each product and manufacturer. Do not mix partial kits, or alter mix ratios. Mix materials in same temperature and humidity conditions specified in paragraph DELIVERY AND STORAGE. DO NOT ADD SOLVENT without specific written recommendation from the manufacturer.

3.5.1.2 Application Conditions and Recoat Windows

Plan coating application to ensure that coating manufacturers temperature, humidity, and condensation conditions are met. If conditions do not allow for orderly application of the coating system use appropriate means of

Section 09 97 13 Page 17 controlling air and surface temperatures, as required. Partial or total enclosures, insulation, heating or cooling, or other appropriate measures may be required to control conditions to allow for orderly application of all required coats.

3.5.2 Application of Coating System, Joint Sealant and Stripe Coat

Apply coatings in accordance with SSPC PA 1 and as specified herein. Apply coatings to surfaces that meet all stated surface preparation requirements.

Prior to application coatings perform testing prescribed in paragraph PRE-

APPLICATION TESTING FOR SURFACE CONTAMINATION, as necessary, to ensure minimal contamination. If contamination is found, revert to the specified testing rate. Such atmospheric events as a coastal storm blowing onshore can bring unusual chloride contamination. Concern for contamination should be continually prevalent, and spot testing should be accomplished to verify satisfactory conditions. Where visual examination or spot testing indicates contamination, perform sufficient testing to verify non-contamination, or to define extent of contamination for appropriate treatment.

Apply coatings in a consistent wet film in a continuous half lapped spray coat, overlapping 50 percent of the previous spray pass. In multiple coat applications apply two coats at 90 degree application patterns. Ensure that

"cold joints" are no less than six inches from welds. Apply stripe coat by brush. For convenience, stripe coat material may be delivered by spray if followed immediately with brush-out and approved procedures include appropriate controls on thickness. Apply all other coats by spray application. Use appropriate controls to prevent airborne coating fog from drifting beyond 10 feet from the structure or containment perimeter]. Cover or protect all surfaces that will not be coated. The cleanliness, temperature, recoat windows, and airborne paint containment requirements may necessitate the use of enclosures, portable shelters, or other appropriate controls.

3.5.2.1 Application of Coating Material

Apply all field applications of coating materials in accordance with manufacturer's printed instructions and literature. Test in accordance with

SSPC PA 2, Appendix 1 and 3 for conformance.

3.5.2.2 Application of Stripe Coat

Apply stripe coat in hard to access areas. Apply by brush, working material into corners, crevices, angles, and welds, and onto outside corners and angles.

3.5.2.3 Procedure for Holiday and Spot Repairs of Newly Applied Coating

Repair coating film defects at the earliest practicable time, preferably before application of the succeeding coat. Observe all requirements for soluble salts contamination, cleanliness between coats, and application conditions. Prepare defective area in accordance with SSPC SP 10/NACE No.

2, and feather coating as required to leave 6 inches of the coating feathered and abraded. Protect adjacent areas from damage and overspray.

Remove dust and solvent wipe the prepared area plus an additional 6 inches beyond the prepared area with clean denatured alcohol. Prepare repairs and apply coating within 48 hours of the general application coat of coating.
