How to Store, Acclimate & Prep for Your Modin LVP Installation

Modin's SPC core is stable enough that formal acclimation isn't required, but proper storage, climate, and a flat subfloor always help in the install process.

  • Climate: 65°F–85°F before, during, and after installation
  • Carton storage: Flat and horizontal at all times, never on end
  • Subfloor flatness: No more than 3/16" over 10 feet
  • Vapor barrier: 6 mil moisture barrier required over any concrete slab
  • Acclimation: 24–48 hours recommended, not required

Storage

Store cartons flat at all times, standing them on end stresses the precision click edges and can damage them before installation. Stacked flat, you can stack as high as you'd like. Keep storage indoors, ideally 40°F–90°F, and protect carton corners from impact.

Acclimation

Acclimation is not required because Modin's SPC core doesn't expand or contract like natural wood. We still recommend 24–48 hours in the install room: the click mechanisms seat best at room temperature, especially after storage or transit in extreme heat or cold. Bring planks to 65°F–85°F before you start clicking.

Subfloor Flatness

No more than 3/16" over 10 feet, the single most important factor in a successful install. Any bumps, dips, and ridges should be fixed. Patch low spots, fill seams and cracks, and level any joints before starting. Use a floor-leveling compound for depressions and a patching compound for cracks.

Installing Over an Existing Floor

  • Resilient sheet vinyl (single layer): Yes, if flat, secured, and dry
  • Ceramic, porcelain, marble, terrazzo: Yes, grout joints filled flush
  • Wood or laminate (on slab): Remove first, can trap moisture
  • Wood or laminate (upper story / crawl space): Lower risk, use judgment
  • Cushioned or padded floors: No
  • Below-grade tile over concrete: No
  • Floor showing signs of warping, or moisture damage: No, remove and test subfloor first

Over a slab, always removing existing wood, vinyl or laminate flooring. By installing a rigid plank on top can trap moisture and warp the material underneath. Risk is lower over a second story or crawl space.

What to Avoid

  • Don't store boxes on end.
  • Don't install in an unconditioned room.
  • Don't skip the flatness check.
  • Don't install over a concrete slab without a 6 mil vapor barrier.
  • Don't cover a floor showing damage or warping.

Common Questions

How long does Modin need to acclimate?

Acclimation is not required for Modin LVP. However, allowing planks to sit in the installation room for 24–48 hours is recommended for best performance, particularly after transport or storage in extreme temperatures.

Do I need a vapor barrier?

Yes. A vapor barrier is required over any concrete slab, even though Modin is waterproof. The barrier protects against slab moisture that can affect the subfloor and adhesive layer beneath the flooring.

Can I install over existing tile or vinyl?

Often yes, if single-layer, well-adhered, flat, and dry. See the table above for what to avoid.
