Use Burn-In Knife
What is Burn-In?
Burn-In is a method used to fill small/big gaps that are present in your cosmetic surfaces. It is an advanced process of shellac stick patching (where a tool was heated over a torch and used to melt shellac sticks to fill in gaps).
The tools used have advanced dramatically. It is common in today’s world to use an electric knife. They are easy to use, maintain constant heat temperature, and have interchangeable tips. Along with the new Burn-In Knife, the materials used have changed as well. We at Touch Up Solutions provide synthetic thermoplastic resin in a wide variety of colors. These Burn-In Sticks vary in sheen properties, flexibility, hardness, and chemical/heat resistance.
The Burn-In method was originally developed for wood repair. But it can also be used non wood surfaces for your laminate repair, furniture repair, leather repair, and tile repair.
First step is to choose a color of burn-in stick that matches the color needed for the wood repair. Typically, the color selected should be lighter than the color of the wood. This will allow an easier process to bring the hue of the Burn-In Stick to match the original color of the wood.
Second Step is to assess the damaged area. Determine if there are any splinters or raised abrasions. If they are present, remove them using a tool like a credit card. Slide the card along the damaged area while holding down the edge at a low angle. If any raised abrasions are present lightly sand the area until it is leveled with the surrounding surface.
Now allow the Touch Up Solutions Burn-In Knife to heat up for five minutes. Once the Burn-In Knife is at the optimal temperature, move it over the damaged area. Rotate the knife where your thumb is facing outward. The corner of the knife should be inclined towards the hole at a 35 to 45-degree angle. Once the Burn-In Knife is in position, carefully touch the Burn-In Stick on the surface of the blade facing upward. The Burn-In Stick should start to melt and flow towards the lower corner of the knife. Do not move the knife or be tempted to shake it for a faster process. Allow the stick to melt in naturally and add more Burn-In Stick if necessary. Once the damaged area is slightly overfilled, move the tip of the knife around so the melted burn-in stick meets all the damaged edges. Lastly, move the Burn-In Knife into the center of the damaged area and slowly lift it straight up. This will assist in removing any present air bubbles that may have formed.
Wipe the Burn-In Knife off with a clean towel and set it down. Now get your Burn-In Balm (helps protect the finish) and apply it over the treated area. As the area cools it should harden. Within a couple minutes, it will be a solid material.
Lastly, sand the area gently in the direction of the wood grain.
