Bilge Paints and Cleaners
Bilge Paints and Cleaners are specialist products within marine paints designed to tackle the unique demands of marine bilge compartments. These are the hidden recesses of a boat’s hull where oil, water, fuel and waste fluids tend to collect - making them prone to corrosion, odours, and contamination. Cleaners in this category are formulated to emulsify oils, break down stubborn grease and loosen built-up sludge in hard-to-reach areas. They help keep bilges clear for inspection, safety and compliance with marine standards, while also preparing surfaces for repainting.

Marine Bilge Paints & Cleaners – Oil-Resistant Coatings and Degreasers for Boats
Bilge Paints and Cleaners serve a critical role in marine upkeep, especially in protecting below-deck compartments exposed to standing water, oil, fuel, and chemical residue. These areas, found beneath engine bays and fuel tanks, require both deep cleaning and long-lasting coatings to remain operational and safe. High-strength bilge cleaners strip away grime that general-purpose detergents cannot handle, helping to eliminate slip hazards and reduce harmful build-up that may mask structural issues.
Once cleaned, bilge areas benefit from specialist coatings that bond to bare or primed substrates and resist the harsh elements common in marine settings. These paints are resistant to alkalis, oil, fuel spills, and seawater ingress. They're also abrasion resistant, helping surfaces withstand regular equipment movement or foot traffic in service vessels. Application is straightforward using a brush or roller, with many products formulated for fast drying in confined, low-ventilation spaces. Our bilge paints are typically white or grey, aiding inspections and helping users detect future leaks or damage.
From fibreglass hulls on pleasure boats to metal service vessels in offshore fleets, bilge paints and cleaners help marine professionals extend vessel life and reduce unplanned maintenance. Whether preparing a bilge for winter layup or maintaining compliance with safety protocols, these products are essential for keeping high-risk areas clean, coated, and fully protected.
Bilge Paint and Cleaner FAQs
Can I use bilge paint on rusted surfaces?
No. Rust must be fully removed or stabilised with a suitable anti-corrosive primer before applying bilge paint. Paint will not bond properly to loose or active corrosion.
Are bilge cleaners safe to use in confined spaces?
Many bilge cleaners are low-odour or solvent-free, but always check the safety data sheet. Use adequate ventilation and personal protective equipment as directed.
Do bilge cleaners leave a residue?
Some cleaners require rinsing with fresh water to avoid residue. Others are formulated as no-rinse solutions. Always follow the label instructions.
How often should I clean and repaint a bilge?
Frequency depends on use. For working boats, inspect and clean monthly. Repainting is typically done every 1–2 years or as needed.
Can I spray bilge paint?
Some products allow spray application, though most are designed for brush or roller use due to access constraints in bilge compartments.
Is bilge paint suitable for saltwater environments?
Yes, most bilge paints in this category are formulated to resist seawater, oil, fuel, and chemical exposure.
What colours are best for bilge areas?
White or light grey is preferred to help with visibility and early leak detection during maintenance checks.
