Overseeing Osmosis Treatment

The treatment of high levels of mositure absorbed by a GRP craft's hull laminate is one of the most talked about issues we have with boat owners. Often we survey boats where the hulls have been overcoated with an epoxy barrier coat and are showing osmotic blistering. 

In most cases this is because the epoxy barrier coat was applied to an unprepared high moisture laminate by the owner who was totally unaware of the consequences. Shea Marine offer a complete advice service to oversee the correct procedure to be carried out on each individual craft with regard to the application of a moisture barrier coat or to rectify a craft with existing osmosis blistering. 

We can also protect you from the unscrupulous boat yard doing excessive work to pump up the bill for no benefit to the vessel.
