Antifouling is the most common (and most important) painting job carried out by boat owners. It is vital to protect your boat using antifouling paint because once fouling has a hold on your hull it will rapidly colonise the surface making it difficult to remove. Applying an antifouling paint to the hull of your boat will prevent the attachment of fouling organisms such as barnacles, weeds and slime - a fouled hull can cause serious problems, therefore prevention is much better than cure. Use biocides safely. Always read the label and product information before use.
