Marine Antifouling Removal
At Gransden Dry Ice Blasters, we specialise in safe, eco-conscious antifouling removal tailored for Portsmouth’s historic and thriving marine scene. Whether you’re moored at Gunwharf Quays, Premier Marina Port Solent, or Haslar Marina just across the harbour, our advanced dry ice blasting technology provides a clean, marina-compliant alternative to traditional abrasive methods.
Environmental regulations around Portsmouth Harbour and the Solent are becoming increasingly stringent, making outdated blasting techniques less acceptable. Our method produces zero secondary waste, is non-abrasive, and fully aligns with the environmental standards expected across the region’s prestigious marinas.
Years of antifouling build-up can cause blistering, flaking, and even damage to the hull — all of which reduce performance and lifespan. Our dry ice blasting process gently strips away old coatings without harming the gel coat, leaving your hull spotless and ready for recoating.
For high-performance coatings like Coppercoat, surface preparation is vital. We guarantee the thorough removal of all previous layers, ensuring proper adhesion and long-lasting protection.

Dry Ice Blasting in Marine Industry
Customer FAQ's
What is dry ice blasting, and how does it work for antifouling removal?
Dry ice blasting is a non-abrasive cleaning method that uses compressed air to accelerate solid CO₂ pellets onto a surface. Upon impact, the pellets sublimate (turn from solid to gas), lifting away layers of antifouling without damaging the underlying gel coat or hull structure. This process leaves no secondary waste, making it ideal for environmentally sensitive areas.
Is dry ice blasting safe for my boat’s gel coat and hull?
Yes. Dry ice blasting is gentle on surfaces and does not involve abrasive materials. It effectively removes antifouling layers while preserving the integrity of the gel coat and hull, ensuring your vessel remains in top condition.
How does dry ice blasting compare to traditional antifouling removal methods?
Unlike sanding or chemical stripping, dry ice blasting is faster, cleaner, and more environmentally friendly. It eliminates the need for harsh chemicals and reduces the risk of surface damage, providing a superior alternative for antifouling removal.
Is the process environmentally friendly?
Absolutely. Dry ice blasting uses recycled CO₂ and produces no secondary waste or harmful emissions. It aligns with environmental regulations and is safe for use in marinas and other sensitive marine environments.
How long does the antifouling removal process take?
The duration depends on the size and condition of the vessel. However, dry ice blasting is generally quicker than traditional methods, often completing the job in a fraction of the time required for sanding or chemical stripping.
Can dry ice blasting be used on all types of boats?
Yes. Dry ice blasting is suitable for various vessel types, including yachts, motorboats, and commercial ships. It effectively removes antifouling from different hull materials, such as fibreglass, steel, and aluminium.
Do you offer mobile services across the UK?
Yes. Gransden Dry Ice Blasting provides a nationwide mobile service, bringing our advanced antifouling removal technology directly to your location for maximum convenience.
How should I prepare my boat for dry ice blasting?
Before the service, ensure the boat is securely positioned and accessible for our technicians. Remove any loose items and cover sensitive areas as advised. Our team will provide specific preparation guidelines tailored to your vessel.
What happens after the antifouling is removed?
Post-removal, your boat’s hull will be clean and ready for inspection or the application of new antifouling coatings. The surface will be free from contaminants, ensuring optimal adhesion and performance of the new coating.
EXCELLENT Based on 8 reviews Posted on SteveTrustindex verifies that the original source of the review is Google. As a digital printer and ink supplier and manufacturer, we had a specialist application that required testing before we went ahead with the blasting itself. This was no problem for Grandsen and we received test results quickly. When it came to the visit itself, it was done at the weekend so it we wouldn't interfere with our business operations. Very happy with the results and the service.Posted on Steve WallerTrustindex verifies that the original source of the review is Google. I cannot rate this company enough! I live in a Grade II Listed property and needed the beams striipped back from being painted black in both the dining room and kitchen. I was pre-warned about the amount of dust that is produced but it is far less clearing up than traditional sand blasting. Also, sand blasting would have taken a lot more of the beams away as some of them were in very poor condition once the paint was removed. But, be aware....... This process still produces a LOT of dust and you will not be able to stop it spreading around the rest of your property. I was prepared for this but even I was surprised how much and how far it spread! Things to note: Only get this done if you are prepared to put up with a LOT of mess. Don't expect the beams to be in perfect condition once they have completed. Some may be rotten, full of filler or may just not look that great. You will need to give the beams some TLC afterwards. I sanded a lot of them down and had to reshape others. Expect to do some making good and filling to the walls and ceilings around the beams. For us, the end product was definitely worth the upheaval as the removal of the black paint has certainly brightened up the rooms. Final shout out goes to the guys who carried out the works who were helpful and friendly.Posted on Nicholas MillsTrustindex verifies that the original source of the review is Google.
