Delamination Meaning in Surfing

Delamination occurs when the outer fiberglass skin separates from the inner foam. This happens when the bond between the resin and core is broken. It often creates a soft or bubbly spot on the surfboard deck. Heat exposure or water entering through a crack can cause this damage. Delamination makes the board much weaker and less responsive during an ocean ride. A surfer notices a large air bubble forming on their favorite board. Fixing this issue requires professional repair to reattach the fiberglass to foam. One rider avoids leaving their surfboard in a hot car to prevent bubbles. Maintaining the structural integrity of the skin is vital for a long life.
