The Wood Repair BCD Cooling Brick is the perfect tool to have at hand when repairing wood with Thermelt Knot Filler. The Cooling Brick is perfect for smaller knots, grains, and cracks. It is easy to grab and put on the warm Knot Filler. The Cooling Brick presses the Knot Filler into the repair, which increase durability, and it quickly cools the Knot Filler so it is ready to be cut.
