Hull Pro - Post-Application Care


Hull Pro’s fouling-release formula self-cleans when vessels are at cruising speed or higher. Friction and pressure are sufficient for pushing growth off the main running bottom and waterline. However, cleaning will be needed as Hull Pro is not an anti-fouling coating. This guide provides our recommended tools for cleaning your Hull Pro treated hull without damaging its performance.

  • Run your vessel once a week at cruising
    Most of the growth will drop off from pressure, except trim tab areas and transom. Do not let vessel sit for long periods collecting growth without a plan to clean or haul out if neglected. This is counter-productive to vessel maintenance.
  • Clean as often as needed
    Everyone’s water will differ, so you may need to clean every few weeks or once a month. Find out what frequency is required in your specific waterway. The growth will be heavier in the transom and bracket/trim tab areas. Use approved tools listed here to get the most effect without damaging the coating. Clean at a frequency until such time you think you can change your cleaning schedule.
  • Prohibit the use of coarse cleaning tools
    Rotating drills with coarse brushes, Scotch Brite, and scouring pads must be specifically prohibited. These cleaning tools can damage the coating one time enough to alter the performance of Hull Pro. Stick soft, silicone or plastic tools.
  • Use non-abrasive tools
    We recommend using dense squeegees, rubber-coated fishing gloves, plastic scrapers and even silicone sponges. Contact of the tool is so important, these certain tools are efficient. Brushes, however, are not.
  • Inspect out of the water & perform routine maintenance
    Pressure washing, to a certain degree, is effective at cleaning out the trim tabs and bracket areas. Pay special attention to and monitor Jack plate engines.
  • Maintain your Hull Pro coating
    Hull Pro is mendable without any prep other than cleaning the surface. Simply roll over damaged areas, if found, let stand for 48 hours, launch and go.
  • Watch growth patterns for your waterway
    Summers are more active, and growth can occur rapidly. Each waterway has its own characteristics, and it’s essential for you to figure out your cleaning frequency. 

Recommended cleaning tools

  • Straight-edge decal squeegee or bondo spreader
  • Dense tint squeegee (silicone / rubber only)
  • Rubber-coated fishing gloves
  • Large magic / melamine sponge
  • Outdoor bleach (optional)

Deferred maintenance

If you’ve falling behind on your cleaning schedule, we have some tips for cleaning your vessel. Remember to check on the rate of growth at your waterway.

  • Falling behind on your cleaning?
    If you’ve fallen behind on cleaning and maintenance, we recommend running the vessel at cruise or somewhere between 35-40 mph or above to knock off heavy growth. This will make a tremendous difference on the effort needed to clean the bottom entirely.
  • Out-of-water maintenance
    For out-of-water service, pressure washing can do the bulk of the heavy lifting, as long as the operator doesn’t get too close. A turbo nozzle is always helpful, and it has been found that staying 4-6 inches away from the surface at up to 4,000 PSI is efficient and safe. After pressure washing, any final cleaning can be done by hand.
  • Green grass / slime, etc.
    Use Outdoor Bleach. Pre-soak the entire bottom of the treated vessel. Apply from tank sprayer. Let stand 3-5 minutes on the hull. Agitate with silicone sponges or soft boat brush. Rinse with pressure washer.
  • Barnacles
    Use a plastic Bondo Scraper or similar tools to pop barnacles off easily. Most can be cleaned away using a silicone squeegee. In tight areas, use flexible plastic tools.
