Definition: The term "delamination" refers to a common surfboard problem occurring when the outer fiberglass coating separates from the foam core which is called a "blank". This forms a bubble of air that will split open if left untreated. This can also lead to water-weight, yellowing, and dangerously sharp edges. Delamination occurs most commonly from age and most horribly from leaving your board in a car in the hot sun.
