Solid wood flooring installation - step by step
Short Answer
Solid wood installation is more involved than engineered or vinyl. Here's the full process.
PRE-INSTALL (2-3 WEEKS):
1. Deliver wood to install room.
2. ACCLIMATIZE 14-21 days in install room (40-60% RH, 18-30°C).
3. Trim door bottoms.
4. Subfloor moisture test (<2% RH for concrete).
5. Plywood subfloor inspection or DPM on concrete.
INSTALLATION DAY:
1. SUBFLOOR PREP:
- Sweep, vacuum, ensure flat (3mm/m), dry, clean.
- For nail-down: confirm plywood condition.
- For glue-down: apply DPM, prime concrete.
2. PLANK DIRECTION PLANNING:
- Run perpendicular to longest wall.
- Reference all rows to first row.
3. STARTING POINT:
- Begin in corner of room.
- 8-10mm expansion gap from walls.
4. INSTALLATION:
- NAIL-DOWN: Nail or cleat through tongue at 30-40° angle.
- GLUE-DOWN: Spread PU adhesive, lay planks into adhesive.
- Maintain consistent stagger.
- Tap planks tight with rubber mallet (through tapping block).
5. CONTINUOUS WORK:
- Standard plank: 400-600 sqft/day.
- Herringbone: 200-300 sqft/day.
6. LAST ROW:
- Cut planks lengthwise to fit.
- Maintain expansion gap.
7. EXPANSION GAP COVERAGE:
- Install transition strips at doors.
- Skirting/beading covers expansion gap.
8. SITE-FINISHING (IF APPLICABLE):
- Sand floor (3 grits).
- Apply stain (optional).
- Apply 2-3 coats of finish.
- Cure 5-14 days.
POST-INSTALL:
1. Furniture moves back 7 days after finish curing.
2. Continue humidity management.
TYPICAL TIMELINE FOR 1200 SQFT APARTMENT:
1. Material delivery + acclimatization: 21 days.
2. Subfloor prep: 2-3 days.
3. Installation: 3-5 days.
4. Site finishing (if applicable): 5-10 days.
5. Cure: 7-14 days.
6. Total: 6-10 weeks.
WHEN TO HIRE A PRO:
- ALWAYS for solid wood. Significant skill required.
- DIY is not recommended.

Detailed Explanation
Solid wood installation is more involved than engineered or vinyl - requiring more skill, more acclimatization time, and more attention to subfloor preparation. Here is the complete process.
PRE-INSTALL PREP (2-3 WEEKS BEFORE INSTALL):
1. WOOD DELIVERED TO INSTALL ROOM. Cartons placed FLAT in the room of installation.
2. ACCLIMATIZATION (14-21 DAYS - CRITICAL):
- Open cartons in install room.
- Allow wood to equilibrate with room temperature and humidity.
- Target: 18-30°C, 40-60% RH stable.
- Skipping this causes post-install movement (gaps in dry, cupping in wet).
3. DOOR PREPARATION. Trim door bottoms for new floor height (10-25mm typical clearance needed).
4. SUBFLOOR MOISTURE TEST. Concrete subfloor must test <2% RH (tighter than engineered's <4%). Use proper moisture meter.
5. SUBFLOOR INSPECTION:
- NAIL-DOWN: Plywood subfloor must be 12mm+ thick, structurally fastened, dry.
- GLUE-DOWN: Concrete subfloor needs DPM (200-micron polyethylene), dry, primed.
6. SUBFLOOR LEVEL. Flat within 3mm per 1 metre.
INSTALLATION DAY - THE FULL PROCESS:
STEP 1: SUBFLOOR PREP.
- Sweep and vacuum thoroughly.
- Confirm flatness with long spirit level.
- Address any high or low spots.
- Ensure dry, clean.
STEP 2: PLANK DIRECTION PLANNING.
- Run planks perpendicular to the longest wall.
- Consider natural light direction (avoid joint lines accentuated by raking sun).
- Plan stagger pattern.
- Sort planks by colour/character to spread variation across the floor.
STEP 3: STARTING POINT.
- Begin in one corner of the room.
- Place 8-10mm spacers between first plank and walls.
- Use a long spirit level to confirm first row is perfectly straight.
STEP 4: INSTALLATION METHOD:
A) NAIL-DOWN (TRADITIONAL):
- Nail or cleat through the tongue at 30-40° angle.
- Pneumatic floor nailer typical (driven by compressed air).
- Nails are hidden in tongue groove - invisible after install.
- 800-1000 nails per 100 sqft.
B) GLUE-DOWN (CONCRETE SUBFLOOR):
- Apply PU adhesive in 1-2m wide strips.
- Lay planks into adhesive, tap firmly.
- Maintain consistent open time before adhesive sets.
- Work in continuous sections.
STEP 5: STAGGER MAINTENANCE.
- Minimum 30cm offset between end joints in adjacent rows.
- Plan ahead - sort cuts to ensure usable lengths in each row.
STEP 6: PLANK SECURING.
- Tap planks tight against neighbour using rubber mallet through tapping block.
- Never strike click edge or plank tongue directly.
STEP 7: WORK CONTINUOUS.
- Standard plank install rate: 400-600 sqft per day per team.
- Herringbone: 200-300 sqft per day.
- Versailles: even slower, specialty.
STEP 8: LAST ROW.
- Cut planks lengthwise to fit remaining gap.
- Maintain 8-10mm expansion gap.
STEP 9: TRANSITION STRIPS.
- Install at door thresholds where solid wood meets other flooring.
- T-mould, reducer, end cap as appropriate.
STEP 10: EXPANSION GAP COVERAGE.
- Skirting/beading over expansion gap.
- Removes spacers, fits skirting tight to floor with appropriate gap behind.
SITE-FINISHING (IF APPLICABLE):
A) FIRST SAND (Coarse 40-60 grit).
- Drum sander for main areas.
- Edge sander for corners and along walls.
- Removes any high spots, smooths plank tops.
B) SECOND SAND (Medium 80-100 grit).
- Removes coarse-sander marks.
C) FINAL SAND (Fine 120-150 grit).
- Final smoothness.
D) VACUUM AND TACK CLOTH.
- Between every grit pass.
E) STAIN APPLICATION (OPTIONAL).
- If changing wood tone.
- 1-2 coats, 24-hour cure between.
F) FINISH APPLICATION.
- 2-3 coats of polyurethane lacquer, water-based polyurethane, or hard-wax oil.
- Each coat: 4-12 hour cure.
- Light sand between coats with 220 grit.
G) FINAL CURE.
- 24-72 hours before light foot traffic.
- 5-7 days before furniture return.
POST-INSTALL:
1. FURNITURE RETURNS 7 days after final finish coat.
2. CONTINUE HUMIDITY MANAGEMENT (40-60% RH).
3. WALK INSPECT - note any developing issues.
4. WALK-OFF MATS at entries.
5. FELT PADS on all furniture.
