Curative Osmosis Treatment for Boats in Málaga
Specialized curative service for hulls with advanced osmosis in Málaga. We repair structural damage, eliminate blisters, and apply durable epoxy barriers to fully restore your boat.
Your vessel in the best hands on the Costa del Sol!
Osmosis occurs when water penetrates through the gelcoat and resin, creating pressure cells that form blisters filled with acidic liquid under the antifouling paint. Over time, this chemical reaction degrades the polyester resin, breaks the hull’s homogeneity, and can compromise its mechanical strength. The most common symptoms are blisters of various sizes, bulging areas, bad smell when broken, and, in advanced cases, softened laminates.
Osmosis produces acidic blisters of 1-5 cm under the gelcoat, soft areas to the touch with an acidic smell when pierced, and progressive loss of structural rigidity that degrades the hull’s polyester resin. Without treatment, it forms a spongy laminate that compromises safety at sea and reduces the boat’s value by 30-50%.

Curative Osmosis Treatment Process
In our specialized workshop in Málaga, we perform the complete osmosis treatment, following a rigorous technical protocol that guarantees lasting results:
- Diagnosis and moisture measurement: We use Tramex equipment, the reference instrument in the nautical sector, to precisely measure laminate moisture and determine the true extent of osmosis.
- Stripping and removal of damaged gelcoat: We remove the antifouling and carefully peel the hull until reaching the healthy structural laminate.
- Acid washing and prolonged drying: We neutralize chemical residues through acid washing and perform complete drying in a controlled capsule, where we adjust temperature and humidity to accelerate the process without compromising the hull structure.
- Grid control: We divide the hull into zones to perform weekly measurements and ensure documented monitoring of the drying progress.
- Filling with epoxy putties: We reconstruct affected areas with high-performance epoxy compounds.
- High-barrier epoxy primers (5+ layers): We apply multiple layers of waterproofing primer that create a total barrier against moisture.
- Final antifouling application: We select and apply the most suitable antifouling based on your vessel’s type of use and navigation conditions.
The result is a comprehensive treatment that restores hull health, improves its water performance, and prevents osmosis recurrence.
