Spring Maintenance 2025 TILE - 1
  • Wash the hull thoroughly with International® Super Cleaner to remove dirt, salt, and grime.
  • Check for cracks in the gelcoat or paint that may need monitoring or repair.
  • If the gelcoat appears dull or chalky, consider buffing, polishing, or repainting to restore its shine.
  • Inspect the hull for osmosis—look for blisters that may weep a vinegar-like fluid.
  • Examine the keel and rudder for impact damage, cracks, or coating detachment.
  • If repairs are needed, grind out affected areas early to allow for proper drying before refinishing.
  • Air out lockers and bilges—open lockers, lift sole boards, and let everything dry.
  • Clean and repaint bilges & lockers if coatings are worn or damaged.
  • Inspect & maintain woodwork—decide what stays bare (e.g., teak decking) and what needs varnishing or sealing.
  • Refresh fresh non-slip deck areas for safety—wash, scrub, and apply two coats of Interdeck® for durability.
  • Assess the current fouling control—if paint is flaking or built up, consider stripping it back.
  • Sand and prepare the surface before applying new fouling control paint.
  • Choose the right fouling control paint based on local conditions and boat type.
  • If switching fouling control brands, check compatibility charts to ensure proper adhesion - Primocon® can be used as a vinyl-based primer suitable for application over most existing coatings.
  • Don’t forget to antifoul your propeller - International® Propeller Primer is a quick drying one-part primer with excellent adhesion properties thanks to Dual-Activated Bonding Technology. Working in combination with our recommended International® antifouling to form a unified coating system that resists dynamic and cavitation forces to protect propellers and underwater metals from fouling build up.

Your boat’s topsides need protection, too! The One UP® and Toplac® Plus system from International® offers:

  • Faster application—fewer coats required for a professional finish.
  • Enhanced UV protection—helps maintain colour and gloss for longer.
  • A smoother, glossier finish—no need for tipping with a brush.
