TO: Dave Guinnup, Leader 

 Sector Based Assessment Group 

FROM: Kaye Whitfield, Project Lead 

Risk and Technology Review - National Emission Standards for Hazardous Air 

Pollutants (NESHAP) for Shipbuilding and Ship Repair (Surface Coating) 

Operations 

SUBJECT: Maximum Achievable Control Technology (MACT) Allowable Emission 

Estimates 

I. Discussion of Actual Emissions and MACT Allowable Emissions

For the most part, the emissions values in the proposed shipbuilding and ship repair 

(surface coating) data sets represent actual emission levels. We discuss the use of “actual 

emissions” versus the use of “MACT allowable” emissions for residual risk assessments both in 

the National Emission Standards for Coke Oven Batteries residual risk final rule (70 FR 19998-

19999, April 15, 2005) and the Hazardous Organic NESHAP (HON) proposed and final residual 

risk rules (71 FR 34428, June 14, 2006, and 71 FR 76609, December 21, 2006, respectively). In 

those actions, we note that assessing the MACT allowable levels of emissions (i.e., the highest 

emission levels that can be emitted while maintaining the same activity level and still complying 

with the NESHAP requirements) is inherently reasonable since they reflect the maximum level 

sources can emit and still comply with national emission standards. However, we also explain 

that it is reasonable to consider actual emissions, where such data are available, in both steps of 

the risk analysis, in accordance with the Benzene NESHAP (54 FR 38044, September 14, 1989). 

Considering actual emissions is reasonable because sources typically seek to perform better than 

required by emission standards in order to provide an operational cushion to accommodate the 

variability in manufacturing processes and control device performance. Failure to consider 

actual emissions data in developing risk estimates would unrealistically inflate estimated risk 

levels. 

 We believe that, for future actions under the RTR program, the most prudent approach is 

to consider not only the actual emissions, but also the emission levels that represent the quantity 

of emissions allowed by the MACT standard (i.e., the “MACT allowable” emissions levels). 

Actual emissions are contained in the NEI-based data sets, available on the RTR website, and 

used for the preliminary risk reports in the docket. For processes that exhibit a greater degree of 

control than what the MACT requires, we expect to see a difference between actual emissions 

levels and the MACT allowable emissions levels. Specifically, we expect the MACT allowable 
2 

emissions to be higher than the actual emissions. For processes that exhibit the control required 

by MACT, we expect to see no difference between actual emissions and the MACT allowable 

emissions. 

We performed a preliminary analysis for the shipbuilding and ship repair (surface 

coating) source category to determine the relationship between the actual emissions levels and 

MACT allowable emissions levels. In the following section, we discuss these preliminary 

analyses and specifically request data to improve them. We will consider any comments 

submitted on the preliminary approach described below, and we will use any new data received 

to refine our MACT allowable analyses. We evaluated potential regulatory amendments for 

proposal considering the risks at both the actual and MACT allowable emissions levels. 

II. Source Category-Specific Summary

As discussed above, we conducted the risk assessment to support this action using the 

actual emissions in the dataset, and we also considered the risks at the MACT allowable 

emission levels by examining the relationship between the actual emission levels and the MACT 

allowable emission levels. For the shipbuilding and ship repair (surface coating) source 

category, the MACT standard requires coating limits for several types of marine surface coatings 

categories, including a general use category and 22 specialty coatings categories. Also, the 

standard requires work practice standards that minimize evaporative emissions and spills from 

the handling, transfer and storage of organic thinning solvents and paint wastes. The MACT 

standard is in the format of volatile organic hazardous air pollutants (VOHAP), and the units are 

grams per liter of coating minus water and exempt compounds. (See Table 1 below for a 

summary of marine coating VOHAP limits from the NESHAP for Shipbuilding and Ship Repair 

(Surface Coating) Operations (60 FR 64330)). 

In the assessment of the actual emissions-to-MACT allowable emissions relationship, we 

identified the highest usage coating categories at several major source shipyards and found the 

reported VOHAP contents were generally 50 to 100 percent of the applicable VOHAP limit, 

depending on the specific types of coatings used at each shipyard. Table 2 summarizes several 

examples of representative coatings with the VOC (surrogate for VOHAP) contents and the 

applicable NESHAP (MACT) coating limit. (There are several marine coating suppliers and 

hundreds of different coatings used at major source shipyards and the listed coatings are only 

intended as examples of high usage coatings based on the surface area of ships.) Based on this 

available information, we estimate MACT allowable emissions to be as high as two times (2X) 

the actual emissions from shipbuilding and ship repair (surface coating) operations.

Amercoat 385 is a high-performance epoxy coating forming a

tough, abrasion-resistant, durable film. It adheres strongly to

bare steel, coated steel and inorganic zinc silicate primed surfaces on new construction, repair and field maintenance projects. Amercoat 385 will also adhere to intact painted surfaces

and tight rust and may be used to repair itself or inorganic

zinc silicate primers.

Amercoat 385 provides an excellent barrier to corrosion; its

inhibitive pigment version (385PA) affords corrosion inhibition at

damaged areas. It has good chemical resistance, making it suitable for use in aggressive environments. Amercoat 385 is userfriendly and can be applied by a variety of methods to produce a

smooth, fast-drying film. It is suitable for immersion in both salt

and fresh water at temperatures up to 140°F, continuous and

can be used as a tank lining for alkaline and salt solutions,

petroleum fuels, and certain chemicals.

Amercoat 385 may also be applied over aluminum, stainless

steel, galvanizing, concrete and previously coated surfaces in

addition to carbon steel.

Amercoat 880 glassflake may be added to increase film build

and lower moisture vapor permeability. For additional information see Amercoat 880 Product Data Sheet or contact your

PPG representative.

dependent upon actual surface temperatures - not simply ambient air temperatures.

Surface temperatures should be monitored, especially with sun-exposed or otherwise

Adhere to all application instructions, precautions, conditions

and limitations to obtain the maximum performance. When

used over recommended primers, refer to application

instructions for the specific primer being used for surface

preparation data and application and drying procedures.

For conditions outside the requirements or limitations

described, contact your PPG representative.

Surface Preparation

Coating performance is proportional to the degree of surface

preparation. Refer to specifications for the specific primer

being used. Prior to coating, primed surface must be clean,

dry, undamaged and free of all contaminants including salt

deposits. Round off all rough welds and remove all weld

spatter.

Steel – Remove all loose rust, dirt, grease or other contaminants by one of the following depending on the degree of

cleanliness required: SSPC-SP2, 3, 6 or 7. For more severe

service and immersion, clean to SSPC-SP10. SSPC-SP12 (WJ2L) is also acceptable over a previously blasted surface. The

maximum soluble salt content for saltwater immersion should

be 3 μg/cm2

. For freshwater immersion, the limit is 2 μg/cm2.

For atmospheric exposure, it can be as high as 10 μg/cm2. The

choice of surface preparation will depend on the system

selected and end-use service conditions.

Blast to achieve a dense, angular anchor profile of 1-2 mils 

(25-50 microns) as indicated by a Keane-Tator Surface

Profile Comparator or Testex Tape. Increase coating thickness if profile greater than 3 mils.

Galvanizing – Remove oil or soap film with neutral detergent or emulsion cleaner; then use zinc treatment such as

Galvaprep® or equivalent or blast lightly with fine abrasive.

Aluminum – Remove oil, grease or soap film with neutral

detergent or emulsion cleaner; treat with Alodine® 1200,

Alumiprep® or equivalent or blast lightly with fine abrasive.

Concrete/masonry – Surface must be cured, clean, dry,

free of contamination and disintegrated or chalky materials. Clean concrete surface; abrasive blast (ASTM D4259)

or acid etch (ASTM D4260). Fill concrete voids with

Amercoat 965 or 114A to achieve a smooth surface. Clean

masonry surface by ASTM D4261. Fill masonry block with

Amerlock® 400BF Block Filler.

Aged coatings – All surfaces must be clean, dry, tightly

bonded and free of all loose paint, corrosion products or

chalky residue. Clean by low pressure water cleaning (1000

psi, min.), SSPC-SP1, 2, 3 or 7. Amercoat 385 is compatible

over most types of properly applied and tightly adhering

coatings. However, a test patch is recommended to confirm

compatibility.

Repair – Prepare damaged areas to original surface preparation specifications, feathering edges of intact coating.

Thoroughly remove dust or abrasive residue before touch up.

Application Equipment

Airless spray – Standard equipment such as Graco Bulldog or

larger with a 0.15- to 0.021- in. (0.38 to 0.53 mm) fluid tip.

Conventional spray – Industrial equipment such as

DeVilbiss MBC or JGA spray gun with 78 or 765 air cap

and “E” fluid tip, or Binks No. 18 or 62 gun with a 66 x

63PB nozzle set up. Separate air and fluid pressure regulators, and a moisture and oil trap in the main air supply

line are recommended.

Power mixer – Jiffy Mixer powered by an air or an explosion-proof electric motor.

Brush – Natural bristle. Maintain wet edge.

Roller – Use industrial roller. Level any air bubbles with

bristle brush.

Application Procedure

Amercoat 385 or 385PA consists of two components which

must be mixed together before use. It is packaged in the

proper portions in 2- or 10-gallon units. 

1. Flush equipment with thinner or Amercoat 12 before

use.

2. Stir each component thoroughly, then combine resin

and cure and mix until uniform. When using Amercoat

880 glassflake, add material to mixed unit of Amercoat

385 following 880. Instructions for use.

3. Thin only if necessary for workability, add Amercoat

101 up to 1

⁄2 pint (approximately 6%) per gallon of

Amercoat 385. Use Amercoat 65 when faster drying is

desired. Use Amercoat 101 when applying in confined

spaces. Use only PPG recommended thinners.

4. Do not mix more material than will be used within pot

life. Pot life is shortened by higher temperatures.

5. For conventional spray, use adequate air pressure and

volume to ensure proper atomization.

6. Apply a wet coat in even, parallel passes; overlap each

pass 50 percent. If required, cross-spray at right angles

to avoid holidays, bare areas and pinholes.

Note: When applying directly over inorganic zincs or

zinc-rich primers, a mist coat/full coat technique may

be required to minimize bubbling. This will depend on

the age of the primer, surface roughness, and environmental conditions during application and curing.

7. When applying antifouling coatings, apply first antifouling coat while Amercoat 385 is still soft to thumb pressure. Failure to apply antifouling while Amercoat 385 is

still soft may result in poor adhesion between coatings

and eventual delamination of the antifouling.

8. Normal recommended dry film thickness per coat is 4

to 6 mils for 385 and 6 to 14 mils for 385 with 880.

However, if greater thickness is applied in local areas

because of overlapping, no runs or sags will normally

occur at a dry film thickness up to 10 mils for 385 and

16 mils for 385 with 880. Total dry film thickness in

two coats must not exceed 16 mils for 385 and 32 mils

for 385 with 880.

9. A wet film thickness of 6 mils (150 microns) normally

provides 4 mils (100 microns) of dry film.

10. When using brush or roller application method, additional coats may be required to achieve proper film

thickness.

11. When a pinhole-free film is required, check film continuity of material with a nondestructive holiday detector

such as Tinker and Rasor Model M-1. Apply additional

Amercoat 385 to areas requiring touch up.

12. Clean all equipment with thinner or Amercoat 12

immediately after use.

Adhere to all application instructions, precautions, conditions

and limitations to obtain the maximum performance. When

used over recommended primers, refer to application

instructions for the specific primer being used for surface

preparation data and application and drying procedures.

For conditions outside the requirements or limitations

described, contact your PPG representative.

Surface Preparation

Coating performance is proportional to the degree of surface

preparation. Refer to specifications for the specific primer

being used. Prior to coating, primed surface must be clean,

dry, undamaged and free of all contaminants including salt

deposits. Round off all rough welds and remove all weld

spatter.

Steel – Remove all loose rust, dirt, grease or other contaminants by one of the following depending on the degree of

cleanliness required: SSPC-SP2, 3, 6 or 7. For more severe

service and immersion, clean to SSPC-SP10. SSPC-SP12 (WJ2L) is also acceptable over a previously blasted surface. The

maximum soluble salt content for saltwater immersion should

be 3 μg/cm2

. For freshwater immersion, the limit is 2 μg/cm2.

For atmospheric exposure, it can be as high as 10 μg/cm2. The

choice of surface preparation will depend on the system

selected and end-use service conditions.

Blast to achieve a dense, angular anchor profile of 1-2 mils 

(25-50 microns) as indicated by a Keane-Tator Surface

Profile Comparator or Testex Tape. Increase coating thickness if profile greater than 3 mils.

Galvanizing – Remove oil or soap film with neutral detergent or emulsion cleaner; then use zinc treatment such as

Galvaprep® or equivalent or blast lightly with fine abrasive.

Aluminum – Remove oil, grease or soap film with neutral

detergent or emulsion cleaner; treat with Alodine® 1200,

Alumiprep® or equivalent or blast lightly with fine abrasive.

Concrete/masonry – Surface must be cured, clean, dry,

free of contamination and disintegrated or chalky materials. Clean concrete surface; abrasive blast (ASTM D4259)

or acid etch (ASTM D4260). Fill concrete voids with

Amercoat 965 or 114A to achieve a smooth surface. Clean

masonry surface by ASTM D4261. Fill masonry block with

Amerlock® 400BF Block Filler.

Aged coatings – All surfaces must be clean, dry, tightly

bonded and free of all loose paint, corrosion products or

chalky residue. Clean by low pressure water cleaning (1000

psi, min.), SSPC-SP1, 2, 3 or 7. Amercoat 385 is compatible

over most types of properly applied and tightly adhering

coatings. However, a test patch is recommended to confirm

compatibility.

Repair – Prepare damaged areas to original surface preparation specifications, feathering edges of intact coating.

Thoroughly remove dust or abrasive residue before touch up.

Application Equipment

Airless spray – Standard equipment such as Graco Bulldog or

larger with a 0.15- to 0.021- in. (0.38 to 0.53 mm) fluid tip.

Conventional spray – Industrial equipment such as

DeVilbiss MBC or JGA spray gun with 78 or 765 air cap

and “E” fluid tip, or Binks No. 18 or 62 gun with a 66 x

63PB nozzle set up. Separate air and fluid pressure regulators, and a moisture and oil trap in the main air supply

line are recommended.

Power mixer – Jiffy Mixer powered by an air or an explosion-proof electric motor.

Brush – Natural bristle. Maintain wet edge.

Roller – Use industrial roller. Level any air bubbles with

bristle brush.

Application Procedure

Amercoat 385 or 385PA consists of two components which

must be mixed together before use. It is packaged in the

proper portions in 2- or 10-gallon units. 

1. Flush equipment with thinner or Amercoat 12 before

use.

2. Stir each component thoroughly, then combine resin

and cure and mix until uniform. When using Amercoat

880 glassflake, add material to mixed unit of Amercoat

385 following 880. Instructions for use.

3. Thin only if necessary for workability, add Amercoat

101 up to 1

⁄2 pint (approximately 6%) per gallon of

Amercoat 385. Use Amercoat 65 when faster drying is

desired. Use Amercoat 101 when applying in confined

spaces. Use only PPG recommended thinners.

4. Do not mix more material than will be used within pot

life. Pot life is shortened by higher temperatures.

5. For conventional spray, use adequate air pressure and

volume to ensure proper atomization.

6. Apply a wet coat in even, parallel passes; overlap each

pass 50 percent. If required, cross-spray at right angles

to avoid holidays, bare areas and pinholes.

Note: When applying directly over inorganic zincs or

zinc-rich primers, a mist coat/full coat technique may

be required to minimize bubbling. This will depend on

the age of the primer, surface roughness, and environmental conditions during application and curing.

7. When applying antifouling coatings, apply first antifouling coat while Amercoat 385 is still soft to thumb pressure. Failure to apply antifouling while Amercoat 385 is

still soft may result in poor adhesion between coatings

and eventual delamination of the antifouling.

8. Normal recommended dry film thickness per coat is 4

to 6 mils for 385 and 6 to 14 mils for 385 with 880.

However, if greater thickness is applied in local areas

because of overlapping, no runs or sags will normally

occur at a dry film thickness up to 10 mils for 385 and

16 mils for 385 with 880. Total dry film thickness in

two coats must not exceed 16 mils for 385 and 32 mils

for 385 with 880.

9. A wet film thickness of 6 mils (150 microns) normally

provides 4 mils (100 microns) of dry film.

10. When using brush or roller application method, additional coats may be required to achieve proper film

thickness.

11. When a pinhole-free film is required, check film continuity of material with a nondestructive holiday detector

such as Tinker and Rasor Model M-1. Apply additional

Amercoat 385 to areas requiring touch up.

12. Clean all equipment with thinner or Amercoat 12

immediately after use.

Adhere to all application instructions, precautions, conditions

and limitations to obtain the maximum performance. When

used over recommended primers, refer to application

instructions for the specific primer being used for surface

preparation data and application and drying procedures.

For conditions outside the requirements or limitations

described, contact your PPG representative.

Surface Preparation

Coating performance is proportional to the degree of surface

preparation. Refer to specifications for the specific primer

being used. Prior to coating, primed surface must be clean,

dry, undamaged and free of all contaminants including salt

deposits. Round off all rough welds and remove all weld

spatter.

Steel – Remove all loose rust, dirt, grease or other contaminants by one of the following depending on the degree of

cleanliness required: SSPC-SP2, 3, 6 or 7. For more severe

service and immersion, clean to SSPC-SP10. SSPC-SP12 (WJ2L) is also acceptable over a previously blasted surface. The

maximum soluble salt content for saltwater immersion should

be 3 μg/cm2

. For freshwater immersion, the limit is 2 μg/cm2.

For atmospheric exposure, it can be as high as 10 μg/cm2. The

choice of surface preparation will depend on the system

selected and end-use service conditions.

Blast to achieve a dense, angular anchor profile of 1-2 mils 

(25-50 microns) as indicated by a Keane-Tator Surface

Profile Comparator or Testex Tape. Increase coating thickness if profile greater than 3 mils.

Galvanizing – Remove oil or soap film with neutral detergent or emulsion cleaner; then use zinc treatment such as

Galvaprep® or equivalent or blast lightly with fine abrasive.

Aluminum – Remove oil, grease or soap film with neutral

detergent or emulsion cleaner; treat with Alodine® 1200,

Alumiprep® or equivalent or blast lightly with fine abrasive.

Concrete/masonry – Surface must be cured, clean, dry,

free of contamination and disintegrated or chalky materials. Clean concrete surface; abrasive blast (ASTM D4259)

or acid etch (ASTM D4260). Fill concrete voids with

Amercoat 965 or 114A to achieve a smooth surface. Clean

masonry surface by ASTM D4261. Fill masonry block with

Amerlock® 400BF Block Filler.

Aged coatings – All surfaces must be clean, dry, tightly

bonded and free of all loose paint, corrosion products or

chalky residue. Clean by low pressure water cleaning (1000

psi, min.), SSPC-SP1, 2, 3 or 7. Amercoat 385 is compatible

over most types of properly applied and tightly adhering

coatings. However, a test patch is recommended to confirm

compatibility.

Repair – Prepare damaged areas to original surface preparation specifications, feathering edges of intact coating.

Thoroughly remove dust or abrasive residue before touch up.

Application Equipment

Airless spray – Standard equipment such as Graco Bulldog or

larger with a 0.15- to 0.021- in. (0.38 to 0.53 mm) fluid tip.

Conventional spray – Industrial equipment such as

DeVilbiss MBC or JGA spray gun with 78 or 765 air cap

and “E” fluid tip, or Binks No. 18 or 62 gun with a 66 x

63PB nozzle set up. Separate air and fluid pressure regulators, and a moisture and oil trap in the main air supply

line are recommended.

Power mixer – Jiffy Mixer powered by an air or an explosion-proof electric motor.

Brush – Natural bristle. Maintain wet edge.

Roller – Use industrial roller. Level any air bubbles with

bristle brush.

Application Procedure

Amercoat 385 or 385PA consists of two components which

must be mixed together before use. It is packaged in the

proper portions in 2- or 10-gallon units. 

1. Flush equipment with thinner or Amercoat 12 before

use.

2. Stir each component thoroughly, then combine resin

and cure and mix until uniform. When using Amercoat

880 glassflake, add material to mixed unit of Amercoat

385 following 880. Instructions for use.

3. Thin only if necessary for workability, add Amercoat

101 up to 1

⁄2 pint (approximately 6%) per gallon of

Amercoat 385. Use Amercoat 65 when faster drying is

desired. Use Amercoat 101 when applying in confined

spaces. Use only PPG recommended thinners.

4. Do not mix more material than will be used within pot

life. Pot life is shortened by higher temperatures.

5. For conventional spray, use adequate air pressure and

volume to ensure proper atomization.

6. Apply a wet coat in even, parallel passes; overlap each

pass 50 percent. If required, cross-spray at right angles

to avoid holidays, bare areas and pinholes.

Note: When applying directly over inorganic zincs or

zinc-rich primers, a mist coat/full coat technique may

be required to minimize bubbling. This will depend on

the age of the primer, surface roughness, and environmental conditions during application and curing.

7. When applying antifouling coatings, apply first antifouling coat while Amercoat 385 is still soft to thumb pressure. Failure to apply antifouling while Amercoat 385 is

still soft may result in poor adhesion between coatings

and eventual delamination of the antifouling.

8. Normal recommended dry film thickness per coat is 4

to 6 mils for 385 and 6 to 14 mils for 385 with 880.

However, if greater thickness is applied in local areas

because of overlapping, no runs or sags will normally

occur at a dry film thickness up to 10 mils for 385 and

16 mils for 385 with 880. Total dry film thickness in

two coats must not exceed 16 mils for 385 and 32 mils

for 385 with 880.

9. A wet film thickness of 6 mils (150 microns) normally

provides 4 mils (100 microns) of dry film.

10. When using brush or roller application method, additional coats may be required to achieve proper film

thickness.

11. When a pinhole-free film is required, check film continuity of material with a nondestructive holiday detector

such as Tinker and Rasor Model M-1. Apply additional

Amercoat 385 to areas requiring touch up.

12. Clean all equipment with thinner or Amercoat 12

immediately after use.

This material is a one pack coating and should always be mixed thoroughly with a power agitator before 

application.

Application by brush is recommended for small areas only. Multiple coats may be required to achieve specified 

film thickness.

Application by roller is recommended for small areas only. Multiple coats may be required to achieve specified film 

thickness. Thinning may be required.

Not Recommended. Use International GTA004 only in exceptional circumstances (max 5% by volume). DO NOT 

thin more than allowed by local environmental legislation.

International GTA004

In the event welding or flame cutting is performed on metal coated with this product, dust and fumes will be 

emitted which will require the use of appropriate personal protective equipment and adequate local exhaust 

ventilation. In North America do so in accordance with instruction in ANSI/ASC Z49.1 "Safety in Welding and 

Cutting."

Work Stoppages and 

Cleanup

 Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with 

International GTA004. Once units of paint have been mixed they should not be resealed and it is advised that 

after prolonged stoppages work recommences with freshly mixed units.

 Clean all equipment immediately after use with International GTA004. It is good working practice to periodically 

flush out spray equipment during the course of the working day. Frequency of cleaning will depend upon amount 

sprayed, temperature and elapsed time, including any delays. Do not exceed pot life limitations.

All surplus materials and empty containers should be disposed of in accordance with appropriate regional 

regulations/legislation.

All work involving the application and use of this product should be performed in compliance with all 

relevant national Health, Safety & Environmental standards and regulations.

Prior to use, obtain, consult and follow the Material Safety Data Sheet for this product concerning health 

and safety information. Read and follow all precautionary notices on the Material Safety Data Sheet and 

container labels. If you do not fully understand these warnings and instructions or if you can not strictly 

comply with them, do not use this product. Proper ventilation and protective measures must be provided 

during application and drying to keep solvent vapour concentrations within safe limits and to protect

PREPARATIONS

NEWBUILDING

Shop primers should be applied using automatic blasting/spraying equipment.

Blast to a minimum of Sa21⁄2 (ISO 8501-1:2007). Steel grit or a mixture of steel grit of particle size 0.6-1.0mm (24-39 

mils) and steel shot of particles size 0.6-1.4mm (24-55 mils) are normally used to give a predominantly angular 

profile.

Apply Interplate 937 before oxidation occurs. If oxidation does occur the entire oxidised area should be reblasted to 

the standard specified above.

Ensure that the area is clean and dry prior to application of Interplate 937.

Consult your International Paint representative for specific recommendations.

primed prior to the application of Interspeed 340.

REPAIR

CDP (Controlled Depletion Polymer) antifoulings can build up a thick leached layer during service which must be 

removed prior to application of Interspeed 340. To remove this leached layer, treat the entire area by close high 

pressure fresh water washing using a fan-jet lance held close to the surface (3,000 p.s.i., 211 kg/cm2) as soon as the 

vessel enters dock and before it dries out. Consult International Paint for alternative methods of surface preparation. 

Repair corroded areas with the recommended primer coating scheme and apply Interspeed 340 (Base Coat) within 

the overcoating interval specified for the primer (consult the relevant primer data sheet).

Ensure that the total area is clean and dry, then overcoat with Interspeed 340 (Top Coat). For overcoating TBT 

copolymer antifoulings, always use Interspeed 340 (Base Coat) as the first coat.

Consult your International Paint representative for specific recommendations.
