Antifouling & painting

Define the coating project clearly

Antifouling the underwater hull and repainting the topsides are different projects with different preparation and scheduling needs. Begin by identifying the areas to be treated and the result you want. Gather records of the existing products if you have them, along with photographs and the date of previous work. Tell the provider where the boat is normally kept and how it is used. Avoid selecting a product solely because another sailor recommends it. The appropriate coating system and preparation need to be assessed for the actual surface, existing finish and intended use of the vessel.

Make preparation visible in the quotation

The final coat is only part of a painting job. Ask the business to explain how the existing surface will be assessed and prepared, and what will happen if it finds a problem beneath the visible finish. Manufacturer guidance from International, for example, distinguishes procedures according to the condition and compatibility of existing coatings. Your provider should use instructions relevant to the selected product and your boat. A quote that lists only paint and labour can conceal very different preparation assumptions. Request a scope that lets you understand what work is included before comparing the totals.

Coordinate the yard and working conditions

Painting work may depend on lifting, washing, support, shelter and the site's rules for preparation and waste. Ask which arrangements the contractor handles and which you need to book separately. Confirm that the yard permits the proposed work and that the contractor understands its requirements. Weather and product instructions can affect timing, so allow the provider to explain a realistic schedule rather than forcing the work into an unsuitable gap. If other trades need the hull or deck, agree on the sequence. A coordinated plan helps protect completed surfaces and avoids paying for preparation twice.

Compare the complete finish, not a colour swatch

For topside or deck work, discuss appearance, texture and the areas included in the finish. Ask how fittings, edges and inaccessible sections will be handled. For underwater coatings, request the specific product and application scope proposed by the professional. Clarify what is excluded and how variations will be approved after the boat is exposed or prepared. If the previous coating is unknown, make that uncertainty explicit. A supplier or applicator should explain the assessment needed rather than assuming compatibility. Written product and scope details make future maintenance easier as well as improving the present comparison between providers.

Record the system for the next maintenance cycle

At handover, obtain the product names, relevant colour details and the date of application, together with the contractor's care and relaunch guidance. Follow the instructions relevant to the completed system and ask questions before the boat returns to service. Keep photographs and invoices with the vessel's maintenance history. These records help the next contractor avoid guessing what lies beneath the surface. Review the completed work against the agreed scope, including edges and areas that are easy to overlook. A coating project is easier to own when the preparation, application and future care are all understood, rather than remembered simply as the year the boat was painted.

Make the first enquiry count.

A coating appointment needs the previous system’s history where available and an assessment of the present surface. Share records and ask the applicator what preparation is proposed. Coordinate the yard window with the work rather than treating paint selection as the entire project.
