Understanding Thermal Shock When Fiberglassing Surfboards
Fiberglassing surfboards involves applying a resin (a type of liquid plastic) to the surfboard to make it strong and smooth. However, if the resin and the surfboard blank (the foam core of the surfboard) are at different temperatures, it can cause thermal shock, leading to problems like uneven curing, orange peel texture, cracks, and air bubbles. Let's explore what thermal shock is, how it happens, and how to avoid it.
