Removing Antifouling

1. Health and Safety

Before commencing preparatory work, ensure the area you are working in is adequately ventilated. Ensure you are wearing the correct PPE; we recommend safety glasses, goggles or visors, nitrile rubber gloves, overalls (ensuring skin is not exposed) and a solvent mask or a respirator (if working on larger areas or in confined spaces).

Before starting your project, always check the weather conditions!


2. Preparation

High pressure fresh water wash, to remove loose antifouling; ensuring all residue and wash water is contained and disposed of, according to local legislation. Mask off areas to be stripped.


3. Applying Interstrip

Apply Interstrip 299E liberally, using an old brush, following the application guidelines provided on the product label.


Leave on the surface. The product needs time to work; the time needed will vary depending on the temperature and the amount of old antifouling on the hull.

For best results, work on a small area at a time – do not allow the product to dry out. See product label for more information.


4. Removing old antifouling

Remove while still soft with a blunt scraper. Interstrip 299E can remove several coats at a time, but heavy build up may require more than one application. Residue should be disposed of according to local regulations.Reapply fresh antifouling after sanding and priming the hull.
