Underwater Primer - Marine Paint and Painting Equipment
Underwater primer is a marine-grade coating applied to steel hulls and submerged structures below the waterline. It normally provides corrosion protection and an adhesion base for compatible antifouling or immersion-service topcoats.
ProShipWorks provides end-to-end support to source and supply Underwater Primer for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Marine coating systems may be specified and tested in accordance with ISO 12944 for corrosion protection. Product-specific technical data sheets determine applicable approvals; IMO PSPC requirements apply only where the coating is specified for regulated ballast-tank service. |
|---|---|
| Class Approval | Approval is product- and coating-system-specific. Acceptance may be available from DNV, ABS, Lloyd's Register, Bureau Veritas, or ClassNK when specified and documented for the vessel application. |
Installation, Maintenance & Safety Information
| Installation Notes | Remove marine growth, salt, oil, rust, and loose coating. Prepare steel to the coating manufacturer's specified standard, commonly abrasive blast-cleaning or approved mechanical preparation. Mix components at the stated ratio and apply within the specified temperature, humidity, pot-life, and recoat limits. Do not assume all products are suitable for application while fully submerged. |
|---|---|
| Maintenance Tips | Inspect underwater coating condition during scheduled hull inspections or dry-docking. Remove fouling and damaged coating, check for corrosion and osmotic blistering, and repair using the original manufacturer's compatible primer and topcoat system. Record batch numbers, preparation standard, and dry-film thickness. |
| Safety Notes | Use the current safety data sheet and product data sheet. Provide ventilation and wear chemical-resistant gloves, protective clothing, eye protection, and suitable respiratory protection. Control ignition sources for solvent-containing products and follow confined-space, permit-to-work, and underwater-work procedures. |
