SPC herringbone flooring combines the durability of rigid core vinyl with the timeless elegance of traditional parquet design.
It looks premium. Architectural. Intentional.
But many DIYers hesitate — because herringbone feels complicated.
The truth?
With the right preparation, accurate layout, and a proper starting triangle, installing SPC herringbone flooring is completely achievable — and incredibly satisfying.
This step-by-step guide walks you through the full installation process, including board measurements, triangle preparation, centre line alignment, expansion gaps, and correct click-lock technique.

Unlike standard straight-lay vinyl plank flooring, herringbone must begin from a precise centre reference point.
If the first triangle is slightly out of alignment, the pattern will gradually drift across the room.
That’s why preparation matters more than speed.
When installed correctly, the result is perfectly symmetrical, clean, and visually striking.
SPC flooring should be:
• Stored flat
• Kept in the installation area for 24–48 hours
• Installed at room temperatures between 18°C – 28°C
This allows the boards to stabilise before installation and ensures dimensional consistency.
The subfloor must be:
• Structurally sound
• Clean and dust-free
• Completely dry
• Flat within 3mm over 2 metres
High spots should be ground down.
Low spots should be filled using a suitable levelling compound.
Skipping proper subfloor preparation is the most common cause of installation issues.
An expansion gap must be left around:
• All walls
• Door frames
• Pipes
• Fixed cabinetry
• Columns
Minimum expansion gap: 6–8mm
Rooms larger than 8m in any direction: increase to 10mm
Do not install under fixed kitchen islands or permanent cabinetry.
For a smooth installation, have the following tools ready:
• Tape measure
• Chalk line (essential for centre alignment)
• Combination square or speed square
• Utility knife with sharp blades
• Rubber mallet (non-marking)
• 6–10mm spacers
• Angle finder
• Straight edge
• Hole saw (for pipes)
Safety gear:
• Safety glasses
• Knee pads
• Dust mask (when cutting)
• Hearing protection (if using power saws)
Understanding plank measurements is essential before starting your herringbone layout.
DECKO SPC Herringbone planks feature:
• 640mm plank length
• Precision A & B plank configuration
• Floating click-lock installation system
To create the starting triangle, specific 45° cuts are required:
• 512mm B board cut
• 256mm B board cut
• 384mm A board cut
• 45° angle cuts on the tongue side
These measurements allow the boards to form a perfectly aligned starting triangle — which determines the accuracy of the entire floor.
The starting triangle is the foundation of your herringbone pattern.
Using the specified measurements and 45° cuts:
Cut the required A and B boards.
Join them together to form the triangle.
Confirm alignment before proceeding.
Once assembled correctly, this triangle becomes your reference base for the entire installation.
Cutting and assembling the starting triangle for accurate herringbone alignment.
Using a chalk line:
Measure and mark the centre of your starting wall.
Snap a straight centre reference line.
Align the centre of your starting triangle precisely to this line.
Accurate centre alignment ensures the herringbone pattern runs symmetrically across the room.
Place 6mm spacers between the boards and the wall.
Continue placing starter triangles along the wall while maintaining:
• Perfect centre alignment
• Consistent expansion gap
• Tight click-lock connections
If this stage is rushed, visible pattern drift may occur later.
Once the base is established:
Connect the long side of the plank first.
Use a rubber mallet with an offcut on the short end.
Gently tap to lock the board into place.
Never hammer directly onto the plank surface.
Repeat the same process:
• Long side connection first
• Tap short end gently to secure
• Maintain the required expansion gap
Continue alternating A and B boards as the pattern expands outward.
The herringbone layout will naturally build across the room in a clean, repeating formation.
Repeat Steps 4 and 5 across the floor.
As you approach walls:
• Measure carefully
• Cut accurately
• Maintain your expansion gap
Precision here ensures a professional finish.
Not marking a true centre line
Even a small misalignment at the start can cause the entire pattern to drift across the room.
Ignoring expansion gaps
SPC flooring needs room to expand and contract with temperature changes.
Installing over an uneven subfloor
Irregularities beneath the boards will affect the locking system and long-term stability.
Hammering directly on planks
Always use an offcut to protect the board edge.
Installing under fixed cabinetry
Floating floors must be able to move freely.
Following proper installation guidelines ensures long-term performance and protects your warranty.
DECKO SPC Herringbone is engineered for stability, durability, and simplified installation.
• Precision A & B plank configuration
• Stable stone polymer composite core
• Waterproof rigid construction
• Floating click-lock system (no glue required)
• Designed specifically for DIY installation
You get the timeless elegance of traditional timber herringbone — without the complexity of glue-down parquet systems.
Can SPC herringbone flooring be glued down?
No. It is designed as a floating click-lock system and should not be glued to the subfloor.
Do I need expansion gaps for SPC flooring?
Yes. A minimum 6–8mm expansion gap is required around all fixed surfaces.
Is SPC herringbone waterproof?
Yes. The rigid core construction is waterproof, but correct installation is essential.
