Surf wax is commonly rubbed on a surfboard deck to improve a surfer’s grip.
The wax creates a textured, tacky surface under the surfer’s hands and feet. Without it, water and the smooth fiberglass or epoxy deck would make it much easier to slip during paddling, pop-ups, and turns.
Modern surf wax is generally made from waxy compounds such as paraffin and related ingredients. Formulas are sold for different water temperatures: harder wax is suited to warm water, while softer formulas remain grippy in cold water.
Surfers normally apply a base coat first and then add a top coat designed for the conditions. Surf wax is different from resin, which is used in board construction and repairs. It is also not the same as traction pads, which are permanently attached textured pieces often used beneath the back foot.
