Repainting your boat not only gives it a fresh, vibrant look but also helps protect it from the harsh conditions of the water. Whether you’re dealing with peeling paint or marine growth buildup, knowing how to properly remove old paint and apply a new coat is essential for maintaining your boat's longevity and performance. In this eight-point guide, we walk you through each step of the repainting process—from cleaning and stripping the old paint to preparing and priming the surface for a new coat.
We also share tips on choosing the right marine paint for UK's inland & coastal waters, protecting areas you don’t want to paint, and following environmental regulations. Whether you're a seasoned boater or a first-time boat owner, the information we share here will equip you with the knowledge you need to give your boat a new perfect paint job.
How to Remove Paint from Your Boat
Repainting your boat is a rewarding but detailed process. The first and most crucial step is to remove the old paint and prepare the surface properly.
1. Clean the Boat Thoroughly
Begin by thoroughly cleaning your boat using a marine cleaner and water. This removes dirt, salt, and marine growth. If you have a pressure washer, it's a great tool for removing loose debris and makes the job a little quicker. Ensuring the boat is free from any contaminants is essential for paint adhesion. Allow the boat to fully dry before proceeding to the next steps.
2. Strip the Old Paint
Once the boat is clean, you can remove the old paint through sanding or using a chemical paint stripper. Sanding requires a dual-action sander with 80-120 grit sandpaper to smooth the surface without damaging the boat's material. For chemical strippers, make sure to use products that are safe for the environment and compatible with the material of your boat. Follow all safety guidelines and wear protective gear while working. Use a scraper to tackle hard-to-reach areas if needed.
3. Repair and Prime the Surface
After removing the paint, check the boat’s surface for damage, such as cracks, holes, or blisters. Marine-grade fillers should be used for repairs. Afterwards, sand the repaired areas again with finer grit (180-220) to ensure the surface is perfectly smooth. Once everything is smooth, apply a primer designed for your boat's material (fibreglass, metal, or wood). This step is essential for ensuring that the new paint adheres properly and lasts as long as possible.

Applying Your Boats New Paint
Now that your boat is prepped and ready, the next step is applying the new coat of paint.
1. Choose the Right Paint
When selecting a paint for your boat, especially for use in UK waters, it's crucial to use a marine-grade paint designed for your environment. Antifouling paints are normally used on the bottom of the boat as they prevent the buildup of marine growth. You'll also want to choose a paint that matches your boat’s material, whether it's fibreglass, wood, or metal. We stock paints from International, Hempel, Epifanes & Teamac. Please contact us for advice on the right choice.
2. Surface Preparation Before Painting
Before applying new paint, ensure the surface is clean, dry, and primed. Sanding down the old surface and applying a primer suitable for your boat’s material will create a better bond between the paint and the boat. This prevents issues like peeling and uneven coverage.
3. Protect Areas That Shouldn’t Be Painted
Before you begin painting, it’s important to mask off areas that shouldn’t be touched by the new paint. High-quality marine tape can protect fittings, rails, and other surfaces, while plastic sheeting or canvas can cover larger areas. Be sure to remove these materials before the paint dries fully to avoid tearing or peeling.
4. Follow Environmental Guidelines
Be aware of environmental regulations when painting your boat, particularly regarding paint disposal and work conducted near water. Antifouling paints can contain harmful chemicals, so it's crucial to take precautions like using drip trays and tarps to prevent spills. Several UK Environmental Agencies provide guidelines to ensure your boat painting process doesn’t harm the environment. You can read the IWA guidelines here.
5. Ideal Weather Conditions for Painting
Finally, always consider the weather when planning your painting project. The ideal conditions are dry, with temperatures between 10°C and 25°C, and low humidity. Moisture can cause poor adhesion, bubbling, or peeling. Avoid painting in direct sunlight, as this can cause the paint to dry too quickly, leading to a patchy or uneven finish. Check the forecast before starting and aim for a dry period to allow sufficient time for the paint to cure properly.
