Why Dryback for Commercial
Four reasons glue-down
wins in commercial settings.
01
No edge lifting under rolling loads
Floating click assemblies can lift at plank edges under repeated rolling loads — housekeeping carts, IV stands, luggage trolleys, pallet jacks. A fully bonded Dryback assembly eliminates this failure mode entirely. Required for any specification involving heavy wheeled equipment.
02
Thinner profile — no transition strips
At 2.5mm total thickness, LVT Dryback installs flush under door clearances that a 5–6mm click product cannot meet without costly transition work. For hotel renovations, healthcare refits, and airport gate areas where door hardware cannot be changed, this matters.
03
Dimensional stability at any width
The bonded installation means the floor cannot move laterally. Floating assemblies require expansion gaps and T-bars in wide-open areas. A glue-down installation in an airport concourse or hotel ballroom has no perimeter gap management requirements and no mid-room transition strips.
04
Anti-skid fiberglass core
Ecoflors LVT Dryback includes a fiberglass stabilizer layer and anti-skid backing. The fiberglass prevents the curling that undermines standard LVT in temperature-variable spaces. The anti-skid backing works with pressure-sensitive adhesives including the Happy Feet HF9200 spray system.

Why spray adhesive for LVT Dryback?
Spray adhesives provide even coverage across the fiberglass-backed LVT surface without the trowel ridges that can telegraph through thin vinyl products. The pressure-sensitive formulation allows repositioning during layout and provides consistent tack across large commercial floor areas.
Subfloor moisture is the critical pre-check
Apply adhesive only after moisture testing confirms the slab is within spec. Calcium chloride test: maximum 3 lbs per 1,000 sqft per 24 hours. In-situ RH probe: maximum 75%. Excess moisture will prevent full adhesive cure regardless of product quality.
⚠ Do not apply adhesive to the plank back
HF9200 is a subfloor-applied spray adhesive. Applying it to the back of the LVT plank will result in uneven coverage and potential bond failure. Spray to the prepared subfloor, allow full flash time, then lay the planks into the tacky adhesive.
Installation Guide
Seven steps to a
correct commercial installation.
01
Moisture testing — before anything else
Test concrete subfloor moisture using calcium chloride test (max 3 lbs per 1,000 sqft per 24 hours) or in-situ relative humidity probe (max 75% RH). Do not proceed if moisture exceeds limits — apply moisture barrier primer first and retest after 24 hours.
Skipping moisture testing is the most common cause of adhesive bond failure and LVT curling in commercial installations.
02
Subfloor flatness — 3/16″ per 10 feet
Check flatness with a 10-foot straightedge. Grind high spots. Fill low spots and cracks wider than 1/16 inch with Portland cement-based patching compound — not gypsum-based products. Target: no more than 3/16 inch (4.8mm) variation per 10 feet. Stricter tolerance than SPC floating installation.
03
Acclimatization — 24 hours minimum
Acclimatize LVT Dryback planks in the installation space for a minimum of 24 hours at 65–85°F (18–29°C). Maintain HVAC at normal operating conditions during installation and for 24 hours after. Do not install on a freshly poured slab — minimum 60-day cure before LVT installation.
Stack cartons flat — do not store planks on edge. Vertical storage can cause planks to develop a pre-set bow before installation.
04
Layout planning — centerlines first
Establish centerlines using chalk lines. Plan layout so border planks are at least half-width. For 228.6×1524mm planks, stagger end joints by a minimum of 6 inches between rows. Dry-lay the first three rows before applying adhesive to confirm layout and direction.
05
Adhesive application — HF9200 spray
Apply Happy Feet HF9200 spray adhesive to the prepared subfloor. Allow the adhesive to fully flash off (become uniformly tacky — not wet) before placing planks. Work in sections to maintain open time. Do not apply adhesive to the back of the plank.
Laying planks into wet (not fully flashed) adhesive is the second most common installation error. The adhesive must be uniformly tacky before plank placement begins.
06
Plank placement and rolling
Press planks firmly into the tacky adhesive using hand pressure. Maintain straight lines using chalk guides. Roll the entire installed area with a 100 lb (45 kg) roller in both directions within 30 minutes. Rolling ensures full contact bond across the anti-skid fiberglass backing — skipping this step reduces bond strength significantly.
07
Cure and protection
Keep foot traffic off the floor for a minimum of 24 hours. Protect from rolling loads for 72 hours to allow full adhesive cure. Do not wet-mop the floor for 72 hours after installation. Install base molding after the adhesive has fully cured.
Place protective cardboard or Ram Board over the new floor before opening to construction traffic. Adhesive that has not fully cured can be dislodged by concentrated point loads from scaffolding feet or ladder bases.

Frequently Asked Questions
Questions US buyers
ask before specifying.
The US commercial standard is 2.5mm total thickness with a 0.55mm (22 mil) wear layer, in a 9×60 inch (228.6×1524mm) plank format. This reaches ASTM F1700 Class IV (heavy commercial). For healthcare and WELL v2 projects, GREENGUARD Gold certificate 135462-420 should be specified. For LEED v4 commercial projects, FloorScore SCS-FS-05154 is required for EQ Credit 2.
Happy Feet HF9200 LVP & LVT Spray Adhesive is a proven choice for LVT Dryback installation in US commercial projects. Apply to the prepared subfloor, allow full flash time until uniformly tacky, place planks, and roll with a 100 lb roller within 30 minutes.
LVT Dryback is glue-down — bonded directly to the subfloor. This eliminates edge-lifting under rolling loads and works in thinner profiles under door clearances. SPC Click is floating installation — faster to install and replace, ideal for BTR and multifamily units. For airports, healthcare, and commercial corridors, Dryback is typically specified.
Subfloor must be flat to 3/16 inch per 10 feet. Concrete must pass moisture testing: maximum 3 lbs per 1,000 sqft per 24 hours (calcium chloride) or 75% RH (in-situ probe). All contamination must be removed. Cracks wider than 1/16 inch must be filled with Portland cement patching compound. See US import and spec guide →
In many cases, yes — with conditions. The existing floor must be fully bonded, flat to 3/16 inch per 10 feet, and free of wax or coating. Existing sheet vinyl with embossed texture may require skim coating to prevent pattern telegraphing. Never install over cushion-backed vinyl, carpet, or more than one existing resilient layer.
LVT Dryback from China imports under HTS 3918.10.10.00, subject to the base MFN duty rate plus Section 301 List 3 tariff (currently 25%). Ecoflors provides HTS pre-classified commercial invoices with all shipments. See our US import guide for full tariff details.
The primary US commercial sectors are hotels and hospitality, healthcare and medical facilities, chain restaurants and food service, fitness studios, airports and transit hubs, schools, and multifamily common area renovations. The glue-down method is preferred wherever heavy rolling loads or edge stability are critical.
Yes. Ecoflors LVT Dryback at 2.5mm with 0.55mm (22 mil) wear layer meets ASTM F1700 Class IV (heavy commercial). The product holds FloorScore SCS-FS-05154 for LEED v4 EQ Credit 2, GREENGUARD Gold 135462-420 for WELL v2 and healthcare, and CARB 2 for California and nationwide use.
