Finger-jointed wood – advantages

Finger-jointed wood is produced by using a refinement process to cut shorter pieces of wood through a so-called Finger-jointing are connected to each other. The ends of the pieces of wood are serrated and glued together. The result is a longer, dimensionally stable component with high quality .

Advantages of finger-jointed wood:

• High dimensional stability: Less distortion and deformation than with continuous screeds
• Resource-saving: Efficient use of wood as a raw material
• Consistent quality: weak points are removed
• Less cracking: stresses are reduced, the screed warps are less warped

Finger-jointed wood can have visible joints. These are no shortage , but due to production.

That's fine (no reason for complaint)

• Visible finger joints (tooth structure)
• Colour differences between wooden segments
• Different grains
• Fine glue joints

Important: These characteristics influence not the stability or durability.

This is not okay (reason for complaint / BA reason)

• Open or non-glued joints
• Visible crevices or detachments
• Loose or unstable areas
• Damage to the joints

In these cases, a complaint should be examined.  Click here for our Complaint form

• Close-up of a clean finger jointing
• Slight color differences visible
• Typical finger-jointing – no defect

• Board with clearly visible segments
• Different wood structure is normal

• Several planks mixed (with & without wedge decoration)
• Visual differences are technically harmless

• Open or damaged connection
• Open connection – possible reason for complaint

• Same wood opaque painted
• Barely visible after opaque painting

By mixing pallets, you can get both planks:

• Non-finger-jointed planks
• Finger-jointed planks

Recommendation for construction
If you want the most even look possible:

• Use finger-jointed planks at the bottom
• Consciously choose the visible side
• When in visible use: distribute evenly for a harmonious overall picture
• Choose an opaque paint

This way you achieve the best result in terms of function and appearance.
The positioning has an influence on the appearance!

Preparation

• Keep wood dry and clean
• Easy to grind for better adhesion

Paint types
Glaze (transparent)

• Finger-jointing remains visible
• Wood structure is emphasized

Opaque paint (recommended for visible surfaces)

• Conceals wood grain and finger jointing almost completely
• Ensures a uniform appearance

Recommendation: For a homogeneous look Use opaque paints . Read our guide: Helpful tips for painting the garden shed - Karibu

Finger-jointed wood is:

• stable
• sustainable
• Naturally beautiful

Visual differences are normal and not a quality defect – it's even an upgrade! With the right placement and a suitable coat of paint, a high-quality look can be achieved.
