Safety: Prior to use, obtain, and consult the "Material Safety Data Sheet" of this product for health and safety information. Read and observe all precautionary notices on container labels.

Surface Preparation:

Paint only clean, dry surfaces. Remove all grease, oil, wax, or other foreign material by solvent or detergent washing. (SSPC-SPI)

Compatibility: For pleasure craft applications, please refer to the Sea Hawk Compatibility Guide to ensure compatibility when applying Islands 77 Plus antifouling paint over existing bottom paint.

Previously Painted Surfaces: Islands 77 is suitable for this substrate. For correct procedures please refer to the Application Guidelines.

Fiberglass or Vinyl Ester Hulls: Islands 77 Plus is suitable for this substrate. For correct procedures please refer to the Application Guidelines.

Wood Surfaces: New Work - Sand the wood surface with 80 grit sandpaper, remove the sanding dust with Sea Hawk S-90 Cleaner, allow to dry and apply the first coat of Islands 77 bottom paint. Reduce the first coat (only) 20% with Sea Hawk 2033 Thinner to maximize surface penetration. Next, apply whatever seam compound if needed, allow to dry in accordance with the product label and apply two more coats of Islands 77 Plus without any thinner reduction. 

Aluminum: Islands 77 Plus Antifouling paint may be used on an aluminum hull only when used with the proper barrier coat system described in Technical Bulletin AL1284.  Islands 77 Plus is not to be used on bare aluminum.

Steel Vessels: Sea Hawk Islands 77 Plus antifouling paint is normally used as part of a paint system for underwater hull areas on steel vessels. Nominally, Islands 77 is applied over a properly cleaned existing surface of another antifouling paint or sealer. The surface must be clean and dry prior to application, free of all surface contamination. We highly recommend the hull bottom be high pressure water washed immediately upon haul out with 2,500-3,000 psi clean fresh water. Some areas may need to be cleaned in accordance with SSPC-SP-1 Solvent Cleaning to ensure all oils, grease, and other contaminants are removed. Please refer to additional data below and the section on recommended systems for steel below.

Additional Data For Painting Steel Hulls: If the surface to be painted is also to be repaired with an epoxy primer system, we recommend the area first be grit blasted to SSPC-SP-10 ‘near white metal', cleaned free of dust and blast media and primed in accordance with the primer system specifications. Please refer to the specified primer data sheet for application details. Make sure the first coat is applied within the proper over coating window of the last coat of epoxy primer which is normally while the epoxy is still tacky but cannot be removed with the thumb. Apply at least two coats of Islands 77 antifoulant for best performance.
