No other filler has the combination of benefits Rangate Knot Filler has:
• Speed. Your repair is complete and ready to be cut or sanded in under a minute, instead of hours or days.
• Ease of Use. No mixing or setup is required, and your filler can be applied with any variable-temperature hot glue gun.
• Right for Any Job. Knot Filler can be used in any application- tough enough to be used both indoors and outdoors, and flexible enough to be used for curved fills and on corners. Some colors are flexible and can be easily cut or turned after being applied. Others are hard, and will stand up to heavy wear and tear in uses like flooring.
• Wide Choice of Colors. Match the tone of your wood for a seamless look, or use a contrasting color to highlight it- the choice is yours. Unleash your creativity and experiment!
• Accepts Finish. Knot Filler can be sanded, painted, stained with no special preparation or hazards.
• Non-Toxic. Unlike other filling options, there’s no need to protect against inhaling toxic fumes or particles when working with Knot Filler.
• 5-Year Warranty. We’re confident our Knot Filler rods will last as long as you need them, if stored and used properly.
Each Knot Filler Single-Color Pack contains 9 same-colored knot filler rods, each 295mm long, and 12mm in diameter.
Step 1: Load the polyamide nylon rod 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 10 to 60 seconds, mainly depending on the depth of the repair. Most voids take 10 to 20 seconds.
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.
Removing Knot Filler Rods: Once you've inserted a Knot Filler Rod into your gun and begun to use it, we recommend using the rod completely instead of removing it to use a different color. If you need to remove a rod, turn the gun and wait for the gun to reach the melting temperature of the rod before removing it- this minimizes the risk of damage to the heating element.
If you're doing high-volume work with more than 1 color, we recommend having 2 separate guns.

Our most popular colors are Black, Mahogany, Walnut, Semi-Transparent/Knot and Oak. Our users love these colors for projects like flooring, tabletops, reclaimed wood slabs, and other furniture pieces. These colors can allow you to disguise a knot, or highlight it with contrast for an artistic look. All colors can be painted and stained, which gives you even greater flexibility.
The lower melting temperature knot fillers are great for a quick application- apply, chisel and go. A very light or hand sanding can be applied to finish the repair.
Our medium range temperature variants are the most popular types- they balance the ability to be cut and shaped post-repair with being firm enough to be sanded.
Wenge color filler is designed to endure the highest melting temperature at 410ºF (210ºC). Once applied, cooled and hardened, the repaired pieces can then be finished with a wide belt sander to remove the excess any knot filler.
