Do You Need to Acclimate LVP Flooring Before Installing It?
· 6 min read
Anyone who's installed hardwood knows the drill: the planks sit in the room, unopened, for a week before a single board goes down. So it's a reasonable question when the material changes to LVP — does the same rule apply, or can the crew show up and start cutting the same morning the pallet arrives?
The short answer is that rigid-core LVP is far less fussy about acclimation than wood, but "less fussy" isn't the same as "doesn't matter at all." Here's what's actually going on, and what to do instead of a blind week-long wait.
Why hardwood needs acclimation and LVP mostly doesn't
Solid wood is hygroscopic — it absorbs and releases moisture from the air, expanding and contracting as it does. Install it straight off a cold delivery truck and it can swell after the fact, buckling seams that looked perfect on day one. The week of acclimation lets the wood equalize with the room's humidity before it's locked into place.
Rigid-core LVP is built differently. The core is a stone-plastic composite, not organic wood fiber, so it doesn't absorb ambient moisture the way solid wood does and its dimensional movement from humidity swings is minimal. That's the main reason most manufacturers don't require the multi-day sit-in-the-box period that hardwood does.
What still matters: temperature, not humidity
The one variable that does affect LVP is temperature — specifically, whether the room is within a normal living-space range before install. Vinyl becomes more rigid when cold and slightly more pliable when warm, and installing it at either extreme can affect how cleanly planks click together and how flat they sit.
The practical fix isn't a week of waiting; it's making sure the space has been at normal indoor temperature — generally 65–85°F — for about 24 to 48 hours before installation, and stays there afterward too. That's especially relevant for a new build, a renovation with the HVAC not yet running, or a shipment that arrived in a cold or hot truck. Let the boxes sit in the room, unopened, for that shorter window so the material and the space meet each other at the same temperature.
The subfloor matters more than the acclimation clock
If there's one prep step that gets skipped and causes real problems later, it's not acclimation — it's subfloor condition. LVP telegraphs whatever is underneath it, so a subfloor that isn't flat, clean, and dry will show through as a soft spot, a visible ridge, or a seam that opens over time no matter how carefully the planks were handled beforehand.
- Flat. Most manufacturers spec no more than 3/16" of variance over a 10-foot span. High spots get ground down; low spots get patched.
- Clean. Old adhesive residue, debris, or uneven paint can telegraph through or stop planks from locking properly.
- Dry. Concrete slabs in particular need a moisture check before install — trapped moisture underneath is a warranty issue waiting to happen, not a cosmetic one.
A simple pre-install checklist
Put together, here's what actually protects the install:
- Keep boxes sealed and let them sit in the installation room for 24–48 hours at normal indoor temperature.
- Run the HVAC (heat or A/C, whichever applies) before install day so the room isn't at an extreme.
- Confirm the subfloor has been checked for flatness and, on concrete, moisture — not assumed fine.
- Leave the manufacturer's expansion gap at the walls; LVP still needs room to move seasonally even without a formal acclimation period.
Frequently asked questions
+ Does LVP flooring need to acclimate before installation?
Not in the way hardwood does. Rigid-core LVP's stone-composite core doesn't absorb humidity the way solid wood fiber does, so most manufacturers don't require a multi-day acclimation period. What it does need is 24–48 hours at normal indoor temperature (roughly 65–85°F) before install.
+ Can LVP be installed the same day it's delivered?
It's better not to, mainly for temperature reasons. If the material arrived in a hot or cold truck, or the space isn't yet climate-controlled, giving it a day or two to reach room temperature avoids planks that are too rigid or too soft to click together cleanly.
+ What matters more than acclimation for a good LVP install?
Subfloor condition. A subfloor that isn't flat, clean, and dry causes far more visible problems — ridges, soft spots, seams that open over time — than skipping a short acclimation window ever would.
+ Does LVP expand and contract like hardwood?
Much less. It still moves slightly with large seasonal temperature swings, which is why installers leave an expansion gap at the walls, but the movement is minor compared to solid wood.
