01
Expansion gap 8-10mm
Start left to right with spacers
Begin installation working from left to right. Insert spacers at ends and edges where planks meet the wall to maintain expansion gaps (8-10mm).
💡 Consistent spacing prevents buckling
02
Tongue into groove
Lock the short end
Lock the short end by inserting the tongue into the groove at a slight angle, then drop flat. You should hear a click when the mechanism engages.
🔊 Listen for the click
03
Min 20cm offset
Starter for the second row
Use the leftover plank from the first row as a starter. Ensure at least 20cm (8 inches) between end joints on adjacent rows.
📐 Staggered rows = stronger floor
04
20-30° angle
Lock the long edge
Insert the tongue into the groove at a 20-30° angle. Slide the plank toward the end of the previous plank until the tongue just touches the groove.
📐 Use a 20-30° angle for easy engagement
05
Tap with block
Tap long edge to close gaps
⚠️ IMPORTANT! Use a hammer and tapping block to tap along the long edge. This bridges the gap between plank ends for a tight fit.
🛠️ Never strike planks directly
06
Scrap piece bridge
Bridge gaps with scrap
Attach a scrap piece of flooring to the gap between plank ends. This bridge holds planks in alignment while you tap the long edge.
🧩 Keep scrap pieces handy for bridging
07
Spacer at row end
Lock the final piece in row
Tap the end with a hammer and tapping block to lock the final piece. Insert a spacer at the end. Remove the bridge and continue toward the wall.
🔑 Spacer at every row end
08
Pull bar
Use pull bar for final piece
Use a hammer and pull bar to lock the ends of the final piece in the row. Insert a spacer at the end. Continue row by row.
📐 Pull bar: essential near walls
09
Final row
Complete the final row
Use a hammer and pull bar to lock the long edges of the planks on the final row. Remove spacers and install baseboards.

❓ Frequently Asked Questions
What is the recommended expansion gap for SPC flooring?
Leave 8-10mm gaps at all walls and fixed objects. This allows the floor to expand and contract with temperature changes without buckling.
Can I install SPC flooring over existing tiles or concrete?
Yes. SPC flooring can be installed over most existing hard surfaces including tiles, concrete, and vinyl. Ensure the subfloor is clean, level, and dry before installation.
What is the difference between SPC and WPC flooring?
SPC (Stone Plastic Composite) has a rigid stone-based core for superior dimensional stability and dent resistance. WPC (Wood Plastic Composite) has a softer core with better sound absorption. SPC is more suitable for commercial and high-traffic areas.
How long does it take to install SPC flooring in an average room?
For a 20m² room, a professional installer typically completes the job in 4-6 hours. DIY installation may take 1-2 days depending on experience and room complexity.
Is SPC flooring suitable for bathrooms and kitchens?
Yes. SPC is 100% waterproof, making it ideal for bathrooms, kitchens, basements, and other high-moisture areas. The rigid core does not swell or warp when exposed to water.
Do I need underlayment for SPC click-lock flooring?
Most SPC flooring comes with an attached underlayment pad. If not, you may need a separate underlayment for sound reduction and thermal insulation. Check the product specifications.
