Surface Preparations

• Use in accordance with the standard Worldwide Marine Specifications.
• All surfaces to be coated should be clean, dry and free from contamination.
• High pressure fresh water wash or fresh water wash, as appropriate, and remove all oil or grease, soluble contaminants and other foreign matter in accordance with SSPC-SP1 solvent cleaning.
• Intertuf 262 can be applied over Intergard 269, when used as a holding primer to protect the blast. The primer surface should be dry and free from all contamination and Intertuf 262 must be applied within the overcoating interval specified (consult the Intergard 269 product data sheet)

Newbuilding:

• Where necessary, remove weld spatter and smooth weld seams and sharp edges
• Welds and damaged areas should be blast cleaned to Sa2½ (ISO 8501-1:2007).
• For PVB and unapproved shop primers, the surface should be blast cleaned to Sa2½ (ISO 8501-1:2007) or power tooled to Pt3 (JSRA SPSS:1984)
• Intact zinc silicate shop primers should be prepared by sweep blasting to International Paint standard AS2 or by power tooling to Pt3 (JSRA SPSS:1984).
• For iron oxide epoxy shop primers, ensure the intact primer is clean and dry.

Major Refurbishment:

Underwater Hull/Boottop/Topsides

• Abrasive blast clean to Sa2 (ISO 8501-1:2007). If oxidation has occurred between blasting and application of Intertuf 262, the surface should be reblasted to the specified visual standard
• Surface defects revealed by the blast cleaning process, should be ground, filled, or treated in the appropriate manner
• Intertuf 262 may be applied to surfaces prepared to International Paint Hydroblasting Standard HB2 which have flash rusted to no worse than HB2M. Hydroblasting is only recommended for underwater hull, above water and topside areas
• Intertuf 262 may be applied to surfaces prepared to International Paint Slurry Blasting Standard SB2 where flash rust is no worse than SB2M. Slurry blasting is only recommended for underwater hull, above water and topside areas. Intertuf 262 may be applied using a wash/blast/wash surface preparation method:
• - High pressure (minimum 3000 psi) fresh water wash
• - Abrasive blast clean to Sa2 (ISO 8501-1:2007)
• - Carry out a second high pressure (minimum 3000 psi) fresh water wash
• - Residual salt level must be below 10µg/cm²
• - Visual standard of flash rusting must correspond to no worse than HB2M

Application

Mixing

• Material is supplied in two containers as a unit. Always mix a complete unit in the proportions supplied. Once the unit has been mixed it must be used within the working pot life specified
• (1) Agitate part A with a power agitator
• (2) Combine entire contents of curing agent (Part B) with Base (Part A) and mix thoroughly with power agitator.

Thinner

• International GTA220
• Thinning is not normally required
• Consult the local representative for advice during application in extreme conditions
• Do not thin more than allowed by local environmental legislation.

Airless Spray

• Recommended
• Tip Range 0.53-0.84 mm (21-33 thou)
• Total output fluid pressure at spray tip not less than 176 kg/cm² (2500 p.s.i.)

Conventional Spray

• Application by conventional spray is not recommended

Brush/Roller

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

Cleaner

• International GTA220/GTA822

Work Stoppages and Cleanup

• Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with International GTA220/GTA822. 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 GTA220/GTA822. 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.

Welding

• 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.

Safety

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 against toxic or oxygen deficient hazards. Take precautions to avoid skin and eye contact (ie. gloves, goggles, face masks, barrier creams etc.) Actual safety measures are dependant on application methods and work environment.

Limitations

A system of Intertuf 262 followed by Intergard 263 may be used for the spot repair or upgrade of the following substrates:

• Spot Repair (Suitable Substrates): - Epoxy, Coal Tar Epoxy, Chlorinated Rubber, Vinyl Tar, Tar-free Viny
• Substrates not suitable for repair : - Bituminous
• Upgrade (Suitable Substrates): - Epoxy, Coal Tar Epoxy, Chlorinated Rubber
• Substrates not suitable for upgrading:- Vinyl Tar, Tar-free Vinyl, Bituminous
• Feathered overlap areas must be kept to a minimum

Overcoating information is given for guidance only and is subject to regional variation depending upon local climate and environmental conditions.

Apply in good weather.

Temperature of the surface to be coated must be at least 3°C above the dew point. For optimum application properties bring the material to 21-27°C, unless specifically instructed otherwise, prior to mixing and application.

Unmixed material (in closed containers) should be maintained in protected storage in accordance with information given in the STORAGE Section of this data sheet

Technical and application data herein is for the purpose of establishing a general guideline of the coating application procedures. Test performance results were obtained in a controlled laboratory environment and International Paint makes no claim that the exhibited published test results, or any other tests, accurately represent results found in all field environments.

As application, environmental and design factors can vary significantly, due care should be exercised in the selection, verification of performance and use of the coating.
