  3. Boat Hull Blister Repair

    If you own a boat you may be familiar with blisters. Blisters are typically a cosmetic problem but can be worse if it reaches the fiberglass laminate below.  They occur on the boat hull.  There may be just a few or there could be hundreds of them.  A blister is a de-bond of paint or other coating from the part surface. It is an undesirable rounded elevation of the surface of a plastic with boundaries that are more or less sharply defined. It resembles a blister on the human skin.

    How do blisters occur?  Through osmosis.  Polyester resin and gel coat are fairly water permeable.  Water does pass through though and if there are small voids it can get into them. The water has a chemical reaction with the resin used for making the hull.  It creates an acidic liquid that needs more water to reduce acidity.  This causes it to expand and thus creating a blister.
