NuCore Harper Luxury Vinyl Plank
Harper brings natural hardwood character to every room without the vulnerability of real wood. Our waterproof rigid core construction handles spills, pets, and high-traffic areas while delivering the warmth and grain detail you'd expect from premium timber.
We engineered Harper with a 6 mm profile that balances structural strength and acoustic comfort. The attached cork underlayment absorbs sound and smooths minor subfloor imperfections, so installation moves quickly over most existing surfaces. Whether you're updating a kitchen, mudroom, or basement, Harper installs fast and performs for decades.
Harper construction & specs
Construction & Durability
NuCore Harper is built on our proprietary rigid core technology that resists denting, scratching, and moisture damage. The limestone-polymer composite core won’t expand or contract with humidity changes, maintaining tight seams and a flat surface year-round.
The 0.3 mm wear layer protects against daily wear while preserving the embossed grain pattern. We bond each layer using heat-welding instead of adhesives, creating a monolithic plank that stands up to rolling furniture, pet claws, and dropped objects. The attached cork backing dampens footfall noise and adds thermal insulation, making Harper ideal for second-story installations or rooms above living spaces.
Installation & Subfloor Compatibility
Harper’s click-lock edge profile creates a floating floor that installs directly over concrete, existing vinyl, ceramic tile, or properly prepared wood subfloors. No glue, nails, or specialty tools required.
The rigid core bridges minor subfloor irregularities up to 3/16 inch over a 10-foot span, reducing prep time on older foundations. We recommend a 6 mil poly vapor barrier over concrete and maintaining a 1/4 inch expansion gap around the perimeter. Most rooms install in a single day with basic cutting tools. Harper works with radiant heat systems when surface temperatures stay below 85°F.
Maintenance & Care
Daily maintenance for NuCore Harper requires only sweeping or vacuuming to remove grit that can dull the finish over time. Damp mop with our pH-neutral cleaner or plain water for deeper cleaning.
The waterproof core means spills wipe away without staining or warping the planks. Avoid steam mops, wax-based products, and abrasive scrubbers that can damage the wear layer. For scuffs, a soft cloth with isopropyl alcohol restores the original sheen. We engineer Harper to resist fading from UV exposure, but area rugs and window treatments help preserve color in rooms with intense direct sunlight.

Harper Flooring Questions
Yes, Harper's waterproof rigid core makes it ideal for full bathrooms, powder rooms, and laundry areas. The sealed click-lock joints prevent moisture from reaching the subfloor.
We recommend caulking the perimeter gap with 100% silicone in wet areas to prevent water migration underneath the planks. Ensure adequate ventilation to manage humidity levels, and wipe up standing water promptly to maintain the wear layer's finish.
The 0.3 mm wear layer resists scratching from pet claws during normal activity. We've tested Harper against common household impacts, and the rigid core prevents denting from dropped objects and furniture legs.
For maximum protection, use felt pads under furniture and keep pet nails trimmed. Rolling office chairs and heavy appliances move freely across Harper without damaging the surface. The embossed texture helps camouflage minor surface marks that may develop over years of use.
Harper delivers the visual warmth of hardwood with practical advantages hardwood can't match. The waterproof construction eliminates concerns about spills, humidity swings, and seasonal expansion that plague wood floors.
Installation requires no acclimation period, no sanding, and no finishing—Harper arrives ready to install. The cork underlayment provides better sound dampening than hardwood over most substrates. You sacrifice the ability to refinish, but gain a maintenance-free floor that performs in environments where wood would fail.
Harper installs over most existing hard surfaces including vinyl, VCT, ceramic tile, and properly secured wood flooring. The rigid core bridges minor irregularities, reducing demolition and prep work.
We recommend removing carpet and padding to reach a stable substrate. Embossed or highly textured existing floors may require a leveling compound to prevent telegraphing. The total thickness including underlayment is 6 mm, so door clearances and transitions to adjacent rooms need verification before installation.
Individual planks can be replaced without disturbing the surrounding floor. Remove the baseboard trim, disassemble planks from the nearest wall to the damaged section, replace the affected plank, and reassemble.
For planks in the middle of large rooms, a circular saw can cut out the damaged piece, and a replacement plank with trimmed tongues can be glued into place. We recommend purchasing extra boxes from the same dye lot during initial installation to ensure color consistency for future repairs.
Yes, Harper works with radiant heat systems when surface temperatures remain at or below 85°F. The rigid core composition transfers heat efficiently without degrading over time.
Turn the heating system off 24 hours before installation and bring it back to operating temperature gradually over several days after completion. Avoid rapid temperature changes that can stress the click-lock joints. The cork underlayment provides some thermal resistance, so account for a slight reduction in heating efficiency compared to thinner flooring products.
Basic installation requires a tape measure, utility knife or vinyl cutter, carpenter's square, spacers for expansion gaps, and a tapping block with pull bar for the final row. A miter saw or table saw speeds cuts but isn't mandatory.
No adhesives, nails, or specialty locking tools are necessary. The click-lock system engages with hand pressure and light tapping. For rooms with complex angles or numerous obstacles, a jigsaw helps with curved cuts around pipes and door casings.
