...renew your anti-fouling

Did you know?


  • Topside and antifouling paints and varnish including used brushes, rollers and trays are now classified as hazardous waste


  • Anti-fouling paints work by releasing toxic chemicals into the water. They are regulated as pesticides.


  • Copper biocides in anti-fouling are toxic to water fleas, dragonfly and fish larvae, and cause contamination to be passed up the food chain 




  • The key is to prevent anti-fouling from unnecessarily entering the water. Skirt the hull and use a tarpaulin. Don’t leave a coloured patch under your boat!


  • Dust from sanding paint and antifouling coatings is toxic. Using a dustless vacuum sander will also protect your heath.


  • If you use scrubbing piles, only scrub off the fouling and not residue paint – be careful not to let old or new paint enter the water.


  • Select a marina, club or boatyard which has a ‘scrub-off’ facility which collects residues and wash down.


  • Select the right type of antifouling for your area and boat usage – take advice from your chandlery. Use water-based paints where possible, or low VOC (Volatile Organic Compounds).


  • Look into environmentally friendly bottom paints, such as vinyl, silicone or Teflon, which are suitable for in-water hull cleaning systems. 


  • Apply the right amount of antifouling required and do not spill it – when applying use a sheet to collect drips.
