Do i need to acclimatise flooring before laying it? (2026)
Quick Answer
Usually, yes. Many flooring products should be acclimatised before installation so they can adjust to the room’s normal temperature and moisture conditions. The exact need and method depend on the flooring type and the manufacturer’s instructions, so always check the product guidance first rather than assuming all floors are treated the same.
Overview
Acclimatising flooring means leaving the unopened or prepared flooring materials in the room where they will be laid, under normal living conditions, before installation. This matters most for wood and wood-based products because they can expand, shrink, cup or gap if they are fitted before they have adjusted to the home environment. Even some laminate, rigid core and vinyl products may have storage and conditioning requirements, though these are often different from solid or engineered timber. The key point is that acclimatisation is not just about waiting a set amount of time. It only works properly if the room itself is ready: the building should be weather-tight, wet trades finished, subfloor dry, and heating or cooling running in a normal way. If you bring flooring into a cold garage, damp extension or freshly plastered room, you have not really acclimatised it for installation. The safest approach is to follow the flooring manufacturer’s installation guide exactly, because requirements vary by product, packaging method and subfloor type. If there is any doubt, check the instructions before opening packs, and do not lay the floor until both the room and subfloor meet the stated conditions.
Who this is for
Homeowners and DIYers planning to install laminate, engineered wood, solid timber, bamboo, vinyl or similar flooring indoors.
What you’ll need
- manufacturer’s installation instructions
- the flooring packs
- a clean, dry, weather-tight room
- subfloor prepared to the flooring specification
- basic room temperature and humidity awareness
- moisture test information or test results for the subfloor if required by the manufacturer
Before you start
Check the exact product instructions first. Confirm the room is enclosed and dry, plaster, paint and other wet work are finished, the subfloor has been tested if required, and the heating or cooling is operating as it normally would when the room is in use. Do not acclimatise flooring in a garage, shed or different room if it will be laid elsewhere.
Step-by-step
- 1
Identify your flooring type and read the installation guide
Find the manufacturer’s installation instructions before you open anything. Check whether the product must be acclimatised, whether packs should stay sealed or be opened, how they should be stacked, and what room and subfloor conditions are required.
Why: Acclimatisation rules vary widely. Solid timber often behaves very differently from laminate or vinyl, and using the wrong method can cause later movement or void the warranty.
- 2
Make sure the room is actually ready
Only bring flooring in once the building is weather-tight and the room is at normal occupied conditions. Finish plastering, screeding, painting and other moisture-producing work first. If underfloor heating is involved, follow the flooring and heating guidance before installation.
Why: Flooring adjusts to the environment around it. If the room is still drying out or temperatures are unstable, the flooring can take up or lose moisture and then move after installation.
- 3
Check the subfloor condition
Confirm the subfloor is clean, level and dry enough for the flooring system you are using. If the instructions require moisture testing, do that before installation rather than relying on appearance alone. Fit any required underlay or moisture barrier only as instructed.
Why: Many floor failures blamed on poor acclimatisation are actually caused by excessive subfloor moisture or an unsuitable substrate.
- 4
Place the flooring in the installation room correctly
Move the flooring packs into the room where they will be laid. Store them flat and supported as directed, away from obvious damp, direct heat or strong sunlight. Do not lean boards upright unless the instructions specifically allow it.
Why: Correct storage helps the boards or planks adjust evenly and avoids bending, warping or edge damage before fitting.
- 5
Condition the room and materials for the period stated by the manufacturer
Leave the flooring in the room for the manufacturer’s stated acclimatisation period and under the stated conditions. Keep windows, heating and cooling in normal use rather than creating extreme conditions to speed things up.
Why: The right combination of time and stable conditions allows the flooring to settle closer to the environment it will live in after installation.
- 6
Inspect before laying
Before you start fitting, inspect boards or planks for damage, obvious bowing, swelling, chipped edges, colour variation outside normal expectations, or signs of moisture exposure. Stop if anything looks wrong and check with the supplier or manufacturer.
Why: Once flooring is installed, defects or wrong-site conditions are harder to correct and may not be covered.
- 7
Install exactly to the specified expansion and layout rules
Lay the floor using the manufacturer’s instructions for underlay, adhesive if applicable, direction of lay, stagger pattern and perimeter expansion details. Keep room conditions stable during and after installation.
Why: Even correctly acclimatised flooring still needs space and proper installation technique to cope with normal seasonal movement.
Why this works
Most flooring materials change dimension slightly as temperature and moisture conditions change. Acclimatisation reduces the difference between the material’s storage condition and the room’s service condition, which helps prevent movement-related problems after fitting.
Common mistakes to avoid
- Assuming all flooring needs the same acclimatisation process
- Ignoring the manufacturer’s instructions and relying on a generic waiting time
- Acclimatising flooring in the wrong room, such as a garage
- Laying flooring before the subfloor is dry enough
- Opening packs too early when the product instructions say to keep them sealed
- Trying to heat or dry the room aggressively to speed up conditioning
- Forgetting that underfloor heating often needs a specific installation process
Troubleshooting
Boards gap or shrink after installation
Check whether the room humidity is too low, whether the product was properly acclimatised, and whether expansion guidance was followed. Small seasonal movement may be normal, but persistent issues may need manufacturer advice.
Floor edges lift, cup or crown
Stop and investigate moisture. Check the subfloor, recent wet trades, leaks, cleaning methods and room humidity. Moisture-related distortion often needs the moisture source fixed before any flooring repair.
Click-fit joints keep separating
Recheck subfloor flatness, pack condition, locking-joint damage and expansion gaps. Movement can come from uneven support as well as poor conditioning.
Planks look bowed before installation
Do not install them immediately. Compare what you see with the manufacturer’s tolerances and storage instructions, and contact the supplier if the packs may have been stored or transported incorrectly.

Alternatives
- Choose a flooring product with lower sensitivity to moisture and temperature changes if the room conditions are hard to stabilise
- Delay the installation until the building and subfloor are fully dry and the home is in normal living conditions
Pro tips
- Keep the flooring in the exact room where it will be installed, not just somewhere indoors
- Take a photo of the product label and installation guide before you start
- Do not assume a newly built or recently renovated room is dry just because it looks dry
- If packs arrive visibly wet, torn or badly stored, raise it with the supplier before installation
- Maintain similar room conditions after installation so the floor is not shocked by sudden changes
Safety notes
- Lift flooring packs carefully; they can be heavy and awkward
- Use safe manual handling and ask for help with long packs
- Wear appropriate eye, hearing and dust protection when cutting flooring
- If you suspect damp, mould or water damage in the subfloor, deal with that before installation
Legal & regulatory notes
Warranty conditions often depend on following the manufacturer’s storage, acclimatisation, subfloor and installation requirements. In rented or multi-unit properties, check whether building management, lease conditions or body corporate rules affect flooring changes, especially for acoustic underlays.

Cost considerations
Acclimatising flooring properly usually costs little compared with the expense of lifting and replacing a failed floor. The bigger cost risk is skipping moisture testing, rushing the job, or damaging packs through poor storage before installation.

Frequently asked questions
Do all floors need acclimatising?+
No. Requirements depend on the flooring type and the manufacturer. Some products need careful acclimatisation, while others mainly require correct storage and room conditions.
Can I acclimatise flooring in the garage first?+
Usually that is a poor idea unless the garage has the same conditions as the installation room and the manufacturer allows it. The flooring should normally be conditioned where it will be laid.
Should I open the packs while acclimatising?+
Only if the product instructions say so. Some floors should stay sealed in their packaging during conditioning, while others may have different handling instructions.
What happens if I skip acclimatisation?+
You increase the risk of gapping, swelling, cupping, joint stress or other movement after installation, especially with timber and wood-based floors.
If the room feels dry, can I skip subfloor moisture checks?+
No. Surface feel is not a reliable moisture test. Follow the manufacturer’s requirements for subfloor assessment and testing.
