There is no universal acclimation clock for laminate. NALFA advises following the manufacturer; some products require a period in the installation environment while others do not.
Read the product rule
Check the instructions for the exact plank and packaging. If a period is required, note how the boxes should be stored and what indoor conditions must be maintained.
Condition the room, not just the cartons
The building should be enclosed and at normal living conditions. Leaving cartons in a damp garage or unconditioned space does not prepare them for the room where the floor will be installed.
Record conditions
Temperature, relative humidity, and substrate condition may matter more than an arbitrary number of hours. A project plan should identify the required conditions before delivery.
A practical checklist
- Find the exact product instructions.
- Maintain normal indoor conditions.
- Confirm where and how cartons should be stored.
Is 48 hours always required?
No. Some products recommend that period, but manufacturer-specific instructions control.
General planning information. Site conditions and the selected manufacturer's instructions determine the installation details.
