    Whats in your box?


    How does it work?

    Get started this easy:

    1. Turn on the Wood Repair BCD-540 Knot Filler Gun and let it heat for 7 minutes.

    2. Place your selected Thermelt® Knot Filler Stick into The Knot Filler Gun.

    3. Shoot the Thermelt® Knot Filler into your knot or repair. Make sure to be quick and efficient in the application. 

    4. Quickly and firmly place the cooling iron/block on the Thermelt® Knot Filler and let it cool off.

    5. Slice off excess Knot Filler with the Flush Cutting Chisel. The Knot Filler repair is    ready for this when the cooling iron/block easily comes off the Knot Filler. 

    6. Sand the repair with sanding paper - by hand or machine

    7. You are now ready for surface treatment! Use oil, lacquer, stain, paint etc. 

    •   Never place the Knot Filler gun on the side - leave in standing position
    •   Never pull out a Knot Filler stick of the gun, as this will ruin the chamber! 
    •   Seal the bag with Knot Filler after use.



     This is not a hotmelt glue or glue stick, but acts similarly.
