Cooling the hot Knot Filler is an essential part of the repair process. The aluminum draws heat out of the material, allowing it to solidify quickly and evenly. Any large surface-area piece of conductive metal can work, as long as it covers the entire surface of the repair completely. Our block has a large surface area and a handle to make it easy to apply firm, even pressure across your repair.
