Coating hazards GB 30981.2-S-Pb≤1000-NC; complies with GB 30981.2-2025
When used as part of an approved scheme, this product holds the following certificates: • Food contact - grain cargo (NOHH) • Fire resistance - in accordance with the provisions of the Marine Equipment Directive • Fire resistance - in accordance with low flame spread requirements (Exova Warringtonfire) • Fire resistance - "Smoke and Toxicity" (Exova Warringtonfire). For details, consult the local International (International Paint) representative.
For the paint system best suited to the surface to be protected, consult your local International Paint representative.
Applied in accordance with the standard Worldwide Marine Specifications.
All surfaces to be coated must be clean, dry and free of contaminants.
Wash with high-pressure or ordinary fresh water as appropriate, and remove all oil, grease, soluble contaminants and other foreign matter in accordance with the SSPC-SP1 solvent cleaning standard.
In-service maintenance — bare steel and corroded areas: clean by hand or power tool at least to St2 (ISO 8501-1:2007). Note: all mill scale shall be removed; areas not suitably treated by chipping or needle gun shall be spot-blasted at least to Sa2 (ISO 8501-1:2007). Generally, this method is suitable for grade C or D steel.
Interstores Epoxy Primer is suitable for application over most previous coating systems. Loose or flaking coatings shall be removed to a firm edge, and Interstores Epoxy Primer shall be applied overlapping the existing coating by 2–3 cm (1 inch). Glossy epoxy and polyurethane may require abrading.
Full coat: this product may be applied as a full coat over most general types of existing coatings at least 3 months old. A patch test is recommended before full application over a given generic coating type. For acceptable coating types and the degree of surface preparation required, consult International Paint.
Precise control of film thickness is critical, especially when recoating existing coating systems.
For specific advice, consult your local International Paint representative.
Note: for marine environments in North America, the following surface preparation standards may be used: SSPC-SP10 in place of Sa2.5 (ISO 8501-1:2007), SSPC-SP6 in place of Sa2 (ISO 8501-1:2007), SSPC-SP2 in place of St2 (ISO 8501-1:2007).
The coating is supplied in two containers as one unit. Always mix the entire unit in the supplied ratio.
(1) Stir the base (Component A) with a power mixer.
(2) Mix all of the curing agent (Component B) with the base (Component A) and stir thoroughly with a power mixer.
Normally no thinning is required. Under extreme conditions, consult your local representative for application advice. Do not thin beyond the limits of local environmental regulations.
Airless spray application is not recommended.
Conventional spray application is not recommended.
Recommended
All equipment should be cleaned immediately after use with International GTA220/GTA822. Do not exceed the mixed application time. All remaining paint and empty containers should be disposed of in accordance with applicable local regulations/laws.
If welding or flame cutting is performed on metal coated with this product, dust and fumes will be released; use suitable personal protective equipment and local exhaust ventilation. In North America, follow the instructions in ANSI/ASC Z49.1 “Safety in Welding and Cutting”.

Interstores Epoxy Primer is not suitable for immersion areas.
Optimum performance is obtained when this coating is applied to steel prepared to St2 (ISO 8501-1:2007).
As with all epoxy-based coatings, Interstores Epoxy Primer will chalk when exposed to ultraviolet light.
Recoat data are for guidance only and depend on local climatic and environmental conditions. For specific advice, consult your local International Paint representative.
Apply in good weather. The temperature of the surface to be coated must be at least 3 °C above the dew point. Unless otherwise specifically instructed, raise the paint temperature to between 21 and 27 °C before mixing and application to achieve optimum application performance. Unmixed paint (in sealed containers) must be stored protectively as specified in the Storage section of this product data sheet. The technical and application data given here are intended as general guidance for establishing an application procedure. Test results are obtained in a controlled laboratory environment, and International Paint does not claim that the published test results, or any other test results, accurately represent results obtained in all site environments. Because application, environmental and design parameters vary widely, care must be exercised in coating selection, performance verification and use.
