Osmosis can cause degeneration of areas of the hull which can cause blistering and even cracking. Our team have all the answers for effective treatment and repair.
The Hot Vac Hull Cure System
A state-of-the art treatment system for all osmosis cases. We remove the gelcoat and thoroughly steam clean before Hot Vac pads are applied. Bake cycles are then run on affected areas until moisture levels come down to the correct level.
There is a final steam clean followed by a coat of epoxy resin onto the bare laminate. Epoxy filler is applied with large filling boards. The surface is then faired with sanders and fairing boards to achieve a smooth surface. Four coats of Gelshield Plus are applied in a controlled environment. The Gelshield plus is then sanded smooth, then one coat of Gelshield 200 epoxy primer applied followed by antifouling.
We have a range of top quality products from International to finish.
- Gel Shield Plus
- Gel Shield
- Internal 830
- Finish with International antifouling
How can osmosis be avoided?
To protect against osmosis it is necessary to seal the surface of the hull over the existing gelcoat. The best time to apply an anti-osmosis system is before the boat has been launched. However, protective systems cannot stop osmosis once it has started, or prevent it from occurring in poorly constructed hulls. If your vessel is dry you can use Gelshield 200 as a preventive measure to help reduce the risk of osmosis. To find out more please visit yachtpaint.
