Glue-Down LVP Installation
Handis glue-down LVP installation bonds every luxury vinyl plank directly to the substrate with trowel-applied pressure-sensitive adhesive — the standard install for concrete slabs in basements, rooms with radiant-heat floor systems where the bond conducts heat better than a floating air-gap, and any open run over 1,200 square feet where a floating floor would need expansion T-molds breaking up the visual flow — flatness-checked to 1/8 inch over 6 feet, slab moisture-tested with a calibrated RH probe or calcium chloride test before the trowel goes down, 48 hours of in-room acclimation, the manufacturer-spec adhesive trowel notch sized to plank thickness, full-spread coverage with 100 percent transfer to the plank back, and final transitions at every doorway — from $4,500 on a 300 square foot zone up to $11,000 on a whole-floor slab install. Glue-down is the right install for the most demanding LVP scenarios. The bond is permanent, the floor sits dead flat, foot-fall noise is the lowest of any resilient install, the radiant heat transfers, and the floor handles the highest traffic loads — but the install itself is more technical and the slab work is non-negotiable.

How a Glue-Down LVP Install Works
Eight sequential steps from the slab moisture reading through the final cure window — the actual sequence we follow on every glue-down LVP install.
Pull a Calibrated Slab Moisture Reading
Before any adhesive ships, the tech pulls an RH probe reading (ASTM F2170, target below 75 percent) or a calcium chloride reading (ASTM F1869, target below 3 lb-MVER) and documents it on the estimate. Out-of-spec slabs route to moisture mitigation first.
Flatness Check to 1/8 Inch Over 6 Feet
Substrate flatness checked with a 6-foot straightedge at multiple points. Concrete high spots ground with a diamond cup wheel; low spots patched with self-leveling underlayment, dried, and re-checked. Tighter tolerance than floating click-lock.
48-Hour Acclimation
Product delivered 48 hours ahead of the install crew, boxes stacked flat in the install room, at the home's normal temperature and humidity. Planks reach the actual conditions before they bond to the slab.
Pull Existing Flooring and Prep the Slab
Any existing flooring (carpet, vinyl, VCT, debonded mastic) pulled and disposed. Slab vacuumed and cleaned with the adhesive manufacturer's recommended prep solvent. Any high spots ground flush. Any low spots patched with self-leveling, fully cured before adhesive.
Layout-Plan and Snap Working Lines
Room measured, plank-width division calculated, cut widths at both walls balanced, end-joint stagger planned. Chalked working lines snapped on the slab to keep the first rows running straight across the open space.
Trowel Adhesive and Seat the Planks
Adhesive notch-troweled across a working zone (typically 4 to 6 plank widths ahead of the install crew). Within the open time (30 to 45 minutes), planks seated into the wet adhesive starting at the working line, hand-pressed first, then advanced across the zone.
Roll Every Plank With a 100-Pound Roller
100-pound rolling-floor roller passed in both directions across every newly-seated plank within the adhesive open time. Rolling concentrates the plank weight to bed the adhesive cleanly across the back. Skipping the roll is the most common cause of glue-down failure after wrong-trowel-notch.
24-Hour Foot Traffic Cure, 72-Hour Furniture Cure
Floor is walkable in soft-soled shoes 4 to 6 hours after the last plank seats. Normal foot traffic at 24 hours. Furniture moves back at 72 hours minimum so the adhesive reaches full bond before sustained load. Written cure-window note left at the home.
Glue-Down LVP Pricing
Final pricing depends on product, slab square footage, slab moisture mitigation needed, substrate flatness, and transition count. Slab moisture testing is included in every estimate. Request a free estimate for an accurate quote.

Why Handis for Glue-Down LVP
Glue-down looks like the simpler install. No click-edge to seat, no underlayment to layout, no floating-floor expansion to plan for. The trade is that everything that goes wrong with glue-down LVP is permanent. A spot-spread adhesive job that leaves voids under the plank fails at the voids — and the only fix is to pry the plank off the slab with a putty knife, scrape the adhesive residue, and start over plank by plank. A glue-down install over an untested high-moisture slab debonds in two seasons and lifts the floor wall-to-wall. A wrong-trowel-notch install reads fine for the first month and shows adhesive bleed through the plank seams the second month. We pull the slab moisture reading on every job, use the manufacturer-spec trowel notch, full-spread coverage, and roll with a 100-pound roller within the open time. No shortcuts on the bond.
Estimate
Tell us the room, the substrate (slab is the standard for glue-down — wood subfloors are usually click-lock candidates instead), the square footage, whether radiant heat runs underneath, and the timeline. We pull a calibrated slab moisture reading on the first visit and document it on the estimate before quoting the install date.
Customer Reviews
Glue-down LVP install reviews from real Handis customers.
Glue-down LVP in our Madrona basement over the concrete slab. Tech pulled an RH reading at 78 percent on the first visit and told us we needed sump pump verification and a perimeter drain inspection before the install. Came back two weeks later, slab read 71 percent, install was clean. Two seasons in, no adhesive failure, the floor reads like a real hardwood at standing height.
Glue-down LVP across our radiant-heat kitchen and breakfast nook in our Mercer Island remodel. We had been told a floating floor would insulate the heat — Handis confirmed glue-down conducts heat better and recommended the hard-set urethane upgrade for the radiant zone. Trowel-applied, every plank rolled with the 100-pound roller. Reads warm underfoot in February when the radiant runs.
Whole-basement glue-down LVP in our Ballard daylight basement — 950 square feet on the slab. Tech ran the moisture test, leveled two low spots, troweled the adhesive in working zones, rolled every plank. Install took three days including the floor roll on day two. Three years in, no debonding, no seam bleed, no lift at the perimeter.
Glue-down LVP across our open-plan main floor on a slab in Bellevue — 1,150 square feet. We chose glue-down over click-lock because the open run was too long for a floating floor without expansion T-molds. Tech laid the planks in two days, rolled every plank within the adhesive open time, and the floor reads as one continuous span with no breaks. Worth the extra cost.
Glue-down LVP in a commercial-grade traffic zone — our finished basement is rented out as a daylight studio apartment. The previous click-lock floor failed at the high-traffic path within 18 months. Handis pulled it, leveled the slab, and glued down a new LVP. Two years in, no movement, no seam separation, no wear-pattern in the traffic path.
