Wood Repair Cooling Brick - 50mm x 50mm

The Cooling brick is made from aluminium and acts as a heatsink to quickly cool newly applied Thermelt filler. At the same time it presses the Knot Filler into the repair, increasing adhesion and durability. The Cooling brick is perfect for smaller knots, grains, and cracks. It quickly cools the Knot Filler, speeding up the time taken to make the repair. Use two blocks for edge and corner repairs.
