Knot Filler Starter Kit
- 1 variable-temperature heating gun used to dispense knot filler.
- 1 aluminum cooling block, 80mm x 180mm / 3 x 7 inch dimensions with handle. This tool is used to draw heat out of the hot filler and solidify your repair.
- 1 steel Knot Filler chisel with birch handle. After applying the cooling block, the chisel is used to remove excess filler from the repair surface.
- 1 Mixed Bag of Knot Filler, which contains a variety of colors designed to help you find which works best for your shop. Each bag includes 10 sticks- 3 Black, 3 Cola or Wenge, 2 Mahogany, 1 Walnut, and 1 Semi-Transparent stick. Try them all, and see which you like the best for your product line.
Step 1: Load the polyamide nylon stick into your knot filler gun, and turn it on. Wait for your knot filler gun to heat to the melting point of your chosen Knot Filler color (table below)
Step 2: Use the gun to apply the filler to the wood imperfection. Be sure to apply slightly more at the end of the repair.
Step 3: Use a cooling block to cool down the hot material. Place it on the filled imperfection and let stand for about 30 to 60 seconds, depending on the size of the repair.
Step 4: Using a knot filler chisel, remove any excess filler.
Step 5 (optional): Lightly sand the newly-filled imperfection to blend it and achieve a natural-looking repair.
Our Knot Filler comes in different formulations:
- Some are more flexible, and able to be shaped by hand tools after a repair. These kinds are great for repairs on furniture, cabinet boxes, and other work where the filler needs to be cut or worked post-repair.
- Others are harder, and can stand up to direct wear and tear- this type is very popular in the flooring industry, where even the pressure and abuse from years of being stepped on won't damage the filler. These colors can be blended with a power sander, but can't be easily cut once dry and hardened.
