Knot Filler FAQ
a) a temperature-adjustable glue gun capable of taking .5" diameter rods.
b) a cooling block which is larger than the void you're repairing. The block both packs the material into the void, and draws out the heat from the filler.
c) a wide, flat chisel to shave off the excess material after cooling the repair.
We carry these items, but you can use your own without any problems.
The 3 different melting points have different material properties which make them more suited for some uses.
140°C Melting Point rods can be more easily cut and formed after solidifying. They’re useful for on-site repairs and turning projects, where you can fill voids in your material, and continue to turn the shape the piece afterwards.
160°C Melting Point rods offer a good balance of being able to be both cut and sanded. Because they’re so versatile, they’re an excellent choice for most users. Our two most popular colors, Black and Mahogany, are in this range.
210°C Melting Point rods can’t be easily cut after cooling. Because of their higher melting point, the material can be put through a wide-belt sanding production process. They are ideal for applications like flooring.
About the Gun
To make sure Knot Filler can work with your gun, check that:
i. The gun is designed to work with half-inch (12 mm) diameter rods.
ii. The gun is temperature adjustable and can heat to the temperature of the filler you want to use.
Any gun with both features will work with Knot Filler!
If you need to remove a rod, first heat up he gun to the recommended melting point. Pulling the rod out cold can damage the heating element, if the filler has solidified around it. Once the gun is hot, remove the rod. There will be some remaining filler in the gun- we recommend you use this before changing. If you are regularly using more than one color, we recommend you use a dedicated gun for each.
