Finger Jointing, also known as the finger joint method, is one of the most efficient production techniques in the wood industry offering aesthetic, durable, and economical solutions. This method allows short wood pieces to be joined into longer, stronger, and visually appealing surfaces, and is meticulously applied in Novawood’s high-tech production lines. But what exactly is finger jointing, how is it done, and where is it used? We've covered all the details for you in this blog post.
Finger jointing is a sustainable and structurally strong joining technique used especially to utilize short pieces of wood. It’s also favored for its clean, attractive appearance.
A finger joint is formed by cutting interlocking “fingers” or notches into the ends of wood pieces and joining them with strong adhesives. This method creates longer, continuous wood components from shorter segments, minimizing material waste while increasing structural stability.
The technique originates from traditional carpentry practices and has been adapted into industrial-scale production over time. Thanks to modern machinery, today’s finger joints are far more precise and durable.
Finger jointing is commonly applied to solid wood types such as ash, pine, and iroko. At Novawood, high-durability MUF (Melamine Urea Formaldehyde) adhesives are used, particularly for products intended for outdoor use.
The finger jointing process requires detailed engineering and precise machinery. At Novawood, it is carried out through fully automated production lines.
Short wood segments are selected.
“Finger” patterns are cut into the ends using specialized cutting blades.
The interlocking surfaces are coated with MUF adhesive.
The pieces are pressed together with high pressure.
The finished product is dried and prepared in standard lengths, ready for use.
To ensure outdoor durability, MUF adhesives are preferred as they offer resistance to water and UV exposure. Production involves CNC-controlled machines, specialized finger cutters, and high-tonnage pressing equipment.
While handcrafted finger joints are still seen in traditional woodworking, modern finger joint production is primarily machine-based for greater precision and strength making it the preferred choice in industrial applications.
Finger jointing offers significant structural and economic benefits, though it comes with some limitations. It should be evaluated according to the intended use.
When bonded with the right adhesive and pressing method, finger-jointed wood offers excellent durability especially in outdoor applications where longevity is key.
Finger jointing repurposes short wood segments, making it both eco-friendly and cost-effective. It allows for production of standard-length, consistent-quality materials.
If insufficient pressure or poor-quality adhesives are used, joints may weaken over time. That’s why it's important to rely on trusted manufacturers like Novawood to ensure product integrity.
Materials produced with finger joint technology are widely used both indoors and outdoors, offering aesthetic appeal and functionality. The most common application areas include:
Used in kitchen cabinets, tables, chairs, and panel surfaces. The joint lines contribute to a natural wood look with modern detailing.
Ideal for structural elements like roof beams and wall frames. The fixed length of finger-jointed wood helps save time and labor in construction.
Perfect for joinery due to its stable dimensions and strength, while also offering visual consistency.
Below we have answered some of the questions users frequently ask about Finger Joint:
Is Finger Jointed Wood Water-Resistant?
Yes if bonded with MUF adhesive suitable for outdoor use. All of Novawood’s exterior finger joint products meet this requirement.
Absolutely. The finger patterns add a modern, distinctive touch to the natural grain of the wood, creating visual harmony in applications such as sunscreens and exterior cladding.
Each method serves different purposes. Finger jointing is ideal for length extension, while glulam is better suited for structural elements. The choice should depend on the intended use.
In conclusion, finger jointing technology contributes significantly to modern architecture and manufacturing with its sustainability, durability, and aesthetic value.
