Osmosis Treatment

Osmosis is the largest fiberglass disease, as well as being an aesthetic problem.

A hull affected by osmosis can lose up to 30% of its strength and lose performance in case of high-performance boats.

Resuming the technical problem, the water particles in contact with the outer layer of gelcoat´s vessel, attempt cross this barrier and can reach to the first fiberglass layers and then starts a chemical process calledhydrolysis, where the water begins to break the resin Molecular chain. In this process there is the formation of combings wich under osmotic pressure produces bubbles on the outer surface of the hull.

Delaying the treatment results in a greater contamination in a short period of time.

At CNAlgés we can verify moisture levels and perform the appropriate work to return the original characteristics of the hull.
