The humidity in the fiberglass is the clear and unequivocal signal of a potential osmosis problem – even in the initial state – and, as also happens in wood, of a loss of resistance to fatigue with a decrease in the breaking load.

With special tools it is possible to identify the values ​​that refer to the real presence of water in the fiberglass and in what percentages.

Fiberglass has allowed the worldwide development of pleasure boating, supplanting many other materials for ease of construction, cost-effectiveness and reduced maintenance. It must be worked with professionalism, respecting the technical dictates of good projects, correct renovations, respect for mixing processes, layering, temperatures and it is a material that must not contain any humidity.

When during the construction there is no good catalysis of the polyester, or the polyester used is not suitable for the specific purpose, the humidity infiltrating the gel-coat forms a viscous liquid, with a strong acetic odor, which the water of the sea, and even more the fresh water, further dilutes and, increasing the volume, unfortunately gives rise to the well-known bubbles on the hull.
