Your skis should be dry and at room temperature when you begin.
1. Pour the tar over the ski’s underside. Heat the tar with a blowtorch, so that it becomes more fluid.
2. Heat a 20 to 30 centimetres at a time. Spread the tar over the surface using a soft cloth. Continue until the ski is completely tarred.
3. Repeat until the midsection of the ski is fully saturated.
4. An untreated ski (left); a ski after two applications (centre); a ski after five applications (right).
