Owatrol Marine Strip Paint, Varnish & Antifoul Stripper

Marine Strip is a versatile, water-soluble paint and antifoul stripper that makes removing old coatings from your boat a breeze. Capable of tackling up to 8 layers in a single application, its thick gel formula ensures no drips—even on vertical surfaces.

It’s safe to use on a wide range of materials, including wood, plastic, metal, and GRP, making it ideal for boat maintenance.

With its VOC-free, non-flammable formula, Marine Strip is safe to use in confined or poorly ventilated areas. Plus, it has a long active working time of up to 12 hours, meaning there’s no need for constant supervision. When the job’s done, simply rinse away the stripper with fresh water, making clean-up hassle-free.

However, Marine Strip isn’t suitable for two-component, baked-on, or polyurethane paints and varnishes.

• Water rinsable – Simply wash away with fresh water or a pressure washer.
• Gel consistency – No drips or mess, even on vertical surfaces.
• Long working time – Up to 12 hours for fuss-free use.
• Effective stripping power – Removes up to 8 coats of paint, varnish, or antifouling in one go.

How to Use Marine Strip

Prepare the Surface

• Remove any loose or flaking paint.
• Brush off dirt, moss, or other debris.

Apply Marine Strip

• Always test a small area first.
• Use a roller, brush, or flat blade to apply a thick, even coat.
• Leave Marine Strip to work—typically for a few hours depending on the coating.
• Rinse thoroughly with fresh water, ideally using a pressure washer. For best results, use warm water.

For Wood

• Neutralise stripped wooden surfaces immediately with Owatrol Wood Cleaner to restore colour.
• Avoid letting Marine Strip sit for too long, especially on softwoods or veneers, which may be damaged.

Tips for Best Results

• Always test a small area to determine the required working time.
• Protect plants, shrubs, and surfaces you don’t wish to strip.
• Use between 5°C and 35°C—avoid direct sunlight or hot surfaces.
• Wear gloves, goggles, and protective clothing for safety.

Restrictions

• Not suitable for two-component coatings, baked-on, or polyurethane paints and varnishes.
• Avoid use on aluminium or delicate woods like veneers.
• Do not allow Marine Strip to dry—re-wet with a light mist of water if necessary.
