How is SPC flooring installed - step by step?
Short Answer
SPC click-lock installation is straightforward for a trained installer. Here's the full 10-step process:
PRE-INSTALL (DAY BEFORE):
1. Deliver and acclimatize cartons 24 hours in the install room.
2. Move furniture out; cover/protect adjacent areas.
3. Trim door bottoms to clear new floor height.
INSTALL DAY:
1. Sweep and clean the subfloor; ensure it's level, dry, smooth.
2. Lay underlay (if separate) - overlap seams with tape, no gaps.
3. Plan plank direction - usually parallel to the longest wall or perpendicular to natural light.
4. Start in a corner - left side of room facing the longest wall.
5. Insert spacers (8-10mm) between first plank row and walls - this is the expansion gap.
6. Click-lock first row end-to-end; stagger second row by minimum 30cm.
7. Continue row by row using tapping block and rubber mallet - never hit the click edge directly.
8. Cut last plank in each row to fit - use a circular saw, jigsaw, or score-and-snap tool.
9. Install transition strips at door thresholds; cover expansion gaps with skirting or beading.
10. Vacuum, walk the floor, check for any loose joints, finished.
TYPICAL TIMELINE:
1. 600-800 sqft straight-lay: 1 day, 2-person team.
2. 1200-1500 sqft apartment: 2-3 days.
3. Herringbone or chevron: half the speed (250-400 sqft/day).
POST-INSTALL:
1. Floor walkable immediately - no curing.
2. Furniture can move back same day; ideally wait 24 hours for click joints to fully settle.
3. First clean: damp microfibre mop only, no harsh chemicals for 7 days.

Detailed Explanation
SPC click-lock installation is straightforward when done by a trained installer with the right tools. Here is the complete 10-step process as Material Depot's empanelled installers execute it. This is useful both as a self-install reference (we recommend pro install but some clients DIY) and to know what good installation looks like when you're supervising.
PRE-INSTALL CHECKS (DAY BEFORE INSTALLATION):
1. DELIVERY AND ACCLIMATIZATION. Cartons should arrive at the install site 24 hours before installation. Stack them flat in the room of installation (not stood on edge) to allow temperature acclimatization. SPC technically needs minimal acclimatization compared to wood, but 24 hours allows even temperature distribution and any minor dimensional settling.
2. ROOM PREPARATION. Move all furniture out. Cover/protect adjacent floors that aren't being replaced. Plan the work sequence so you have one continuous open work area.
3. DOOR PREPARATION. Measure clearance between current floor and door bottoms. Most doors need 8-15mm trim to clear the new SPC + underlay height. Trim before install - much easier than removing and trimming a hung door after.
INSTALLATION DAY - THE 10-STEP PROCESS:
STEP 1: SUBFLOOR PREP. Sweep and vacuum the subfloor. Confirm flatness with a long spirit level (within 3mm over 1 metre). Address any high or low spots. Confirm subfloor is dry.
STEP 2: UNDERLAY (IF SEPARATE). Roll out the separate underlay (foam, cork or specialized SPC underlay) if used. Overlap seams 5cm and tape with installation tape. No gaps, no bunching. Skip this step if using SPC with attached IXPE (most premium ranges).
STEP 3: PLANK DIRECTION PLANNING. Decide which direction the planks will run. Standard rule: run parallel to the longest wall, or perpendicular to natural light (so the joint lines aren't accentuated by raking sunlight). For visual unity in open-plan apartments, planks should run in one consistent direction across all open rooms.
STEP 4: STARTING POINT. Start in the room's left corner facing the longest wall. The first plank's tongue edge faces the starting wall, with the groove edge facing into the room.
STEP 5: EXPANSION GAP. Insert 8-10mm plastic spacers between every wall and the first row of planks. This expansion gap allows the entire floor to expand/contract as a unit with seasonal temperature changes. Critical - skipping this causes peaking later.
STEP 6: FIRST ROW INSTALL. Click the first plank into place against the spacers. Click the second plank end-to-end with the first using the end-joint. Continue along the wall. Cut the last plank in the row to length using a circular saw, jigsaw, or score-and-snap tool. Make sure the cut piece is at least 30cm long (if not, cut the first plank shorter to ensure the last piece is usable).
STEP 7: SECOND ROW. The second row starts with a plank that's offset from the first row by minimum 30cm (often using the cut piece from the first row's end). This stagger pattern is critical for both visual aesthetics and structural integrity of the click joint network. Continue staggering each subsequent row.
STEP 8: TAPPING. Use a tapping block and rubber mallet to ensure click joints fully engage. NEVER hit the click edge directly with a hammer - use the tapping block to distribute force. Listen for the click sound and visual flush.
STEP 9: LAST ROW. The last row almost always needs ripping (cutting lengthwise) to fit the remaining gap. Measure individually at multiple points (walls are rarely perfectly parallel). Use a circular saw with a fine-tooth blade.
STEP 10: FINISHING. Remove spacers. Install transition strips at door thresholds where SPC meets other flooring. Install or refit skirting/beading over the expansion gap. Vacuum the floor. Walk it to check for any loose joints, peaks or visible gaps.
TYPICAL TIMELINE:
1. Straight-lay SPC, 600-800 sqft: 1 day, 2-person team.
2. Standard 3BHK apartment (1200-1500 sqft): 2-3 days.
3. Herringbone or chevron pattern: half speed - 250-400 sqft per day. The pattern requires more cutting, more careful alignment.
4. Includes prep, install, and finishing - does not include subfloor levelling (separate scope).
POST-INSTALL CARE:
1. FLOOR IS WALKABLE IMMEDIATELY. No curing time, no drying. You can walk on it the moment the installer leaves.
2. FURNITURE MOVEMENT. Furniture can return the same day. Ideally wait 24 hours to allow click joints to fully settle before placing very heavy items.
3. FIRST CLEAN. Use only a damp microfibre mop for the first 7 days. Avoid harsh cleaners or excessive water while the floor "beds in". After 7 days, full normal cleaning routine.
4. INSTALL INSPECTION (RECOMMENDED). Walk the finished floor with the installer at handover. Check: no peaking joints, no visible gaps, transitions are flush, skirting fitted properly, all click joints sound. Photograph for warranty records.
DIY VS PROFESSIONAL INSTALL:
For 200-400 sqft of straight-lay SPC, a DIY enthusiast with good tools and patience can achieve a good result - the click system is forgiving. For larger areas, herringbone/chevron, or projects with multiple rooms, professional install is strongly recommended. Bad DIY install can void warranty and is hard to fix later. Material Depot's empanelled installers cost Rs 30-45/sqft and typically save 2-3x that in avoided errors.
