The Professional’s Guide to SPC Flooring Installation: 5 Mistakes to Avoid with Unilin Click
Installing SPC flooring is often marketed as a simple DIY task. While the Unilin Click system makes the process significantly faster and more intuitive, professional results require attention to detail.
At Ecoflors, we’ve seen thousands of projects. To ensure your floor remains stable, waterproof, and beautiful for decades, avoid these five common installation blunders.

Note: Pay close attention to the mark where we demonstrate the proper angle for locking planks.
The Pro Tip: Ensure your subfloor is flat within 3mm over a 3-meter radius.
The Consequence: High spots can cause the click joints to stress and eventually snap.
3. Mistake #2: Ignoring Expansion Gaps
SPC is incredibly stable, but it still needs room to “breathe” near walls and fixed objects.
The Fix: Always leave a 6mm to 10mm expansion gap around the perimeter.
Why it matters: Without this gap, the floor may buckle during extreme temperature shifts.
4. Mistake #3: Forcing the Click Lock
One of the greatest advantages of Ecoflors products is the precision-engineered Unilin Click system.

The Pro Tip: If the planks aren’t joining easily, check for debris in the groove. Never use excessive force with a tapping block, as it can damage the delicate locking profile shown above.
5. Mistake #4: Incorrect Staggering (The “H” Join)
For the best structural integrity and aesthetic look, your planks should be staggered.
The Rule: Ensure end joints are at least 20cm to 30cm apart from the previous row.
The Result: This creates a stronger “weave” that holds the entire floor together under heavy foot traffic.
6. Mistake #5: Using the Wrong Underlayment
While many of our wholesale SPC floors come with a pre-attached 1mm or 1.5mm IXPE padding, adding a second layer of soft underlayment is a major mistake.
Why? Too much “cushion” makes the floor too bouncy, which puts fatal pressure on the Unilin Click joints.
