Rigid Core Floating Luxury Vinyl Flooring

Installation Instructions

GENERAL INFORMATION

Engineered Floors LLC® (“EF”) requires all vinyl flooring supplied by EF be installed according to our most current installation

instructions in order to maintain full product warranty coverage. Best practice is to have the flooring installed by professional

installation technicians. The most current installation documents and videos can be found online at www.engineeredfloors.com

Instructions on replacing damaged plank as well as maintenance and warranty documentation are also available online. EF LVF is

intended for indoor use only and is warranted as a floor covering only. Do not install luxury vinyl flooring in areas subject to frequent

standing water or in high moisture areas. Keep the original sales receipt as proof of purchase. Record the date of installation. EF

requires that the flooring be maintained according to our most current care and maintenance guidelines. When ordering flooring,

order 5% more footage than the measured space to receive flooring. Where numerous angles or obstacles exist, more than 5%

overage may be necessary. It is recommended to keep a minimum of one carton for future repair, replacement or for testing

purposes.

COTTAGES AND THREE SEASONS ROOMS

These products can be installed in fully enclosed 3 season environments such as solariums, sun rooms, three season rooms, and

seasonal cottages. Installation in 3 season environments should occur while HVAC is operational and set between 65°F - 85°F (18.3°C

- 29.4°C). These LVF products can withstand ambient temperature variations from -20°F (-29°C) to 176°F (80°C) when not occupied.

While the space is occupied, the ambient temperature must be maintained between 55°F (13°C) and 100°F (38°C). Please see

Conditions and Exclusions section of the EF Luxury Vinyl Flooring Warranty.

SUITABLE SUBSTRATES/GENERAL SUBSTRATE PREPARATION

 EF LVF can be installed on, above, or below grade. EF requires a 6-8 mil polyethylene vapor barrier be installed under our

floating floors that are installed on concrete that is on or below grade.

 The substrate should be free of dust, debris, paint, varnish, wax, grease, oils, curing agents, sealers, solvents and other foreign

matter. Any adhesive residue should be reduced to a thin well bonded residue.

 The substrate must be clean, dry, structurally sound, firm, and secure.

 High spots should be ground. The substrate must be flat within 3/16" per 10 foot radius (4.7 mm per 3 m). Deflection should not

exceed 3/64” (1.1 mm). All construction seams, expansion joints, low areas, grout lines, etc. larger than ¼” should be filled to

level with the surrounding surface using a Portland cement-based patching compound to eliminate telegraphing of such

irregularities.

 Do not install EF LVF over cushion-backed vinyl flooring, asphalt-based floors, carpet and/or carpet pad, self-adhering plank or

tile, laminate or other floating flooring, or structurally- damaged concrete.

 EF floating LVF has an attached underlayment. Do not install over a separate cushioned underlayment.

CONCRETE SUBSTRATES (PORTLAND OR GYPSUM BASE)

New concrete subfloors must be cured for 60 days prior to installation of flooring. All concrete subfloors should be tested for

moisture. The moisture vapor emission rate should not exceed 8 lbs. /1000 sq. ft. per ASTM F1869 and the internal relative humidity

should not exceed 90% per ASTM F2170. The pH level should be between 5 and 9. If the concrete is a gypsum base, a latex primer

may be required to reduce dust (for loose lay) or to reduce porosity (for glue down). Concrete should meet the guidelines of ASTM F

710 “Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring” (see www.astm.org/standards/F710).

WOODEN SUBSTRATES

Wood floors should be a minimum of 3/4" (19 mm) thick APA approved subfloor grade tongue and groove plywood or 23/32" (18.25

mm) OSB. It should have a smooth finish and be free from spring and deflection. If this requirement is not met or known, a minimum

of 1/4" (6.35 mm) APA approved underlayment grade wood must be adhered to the existing substrate. All fastener indentations and

joints should be level and smooth. Use an appropriate patching compound as necessary. If the new floor will be adhered, a latex

primer may be required to reduce porosity and ensure bonding.

EXISTING RESILIENT FLOORS When installing EF LVF over existing resilient flooring, ensure that the existing sheet good or tile product is in good condition and is fully secured to the substrate. EF LVF can be installed over one layer of non-cushioned sheet vinyl flooring. If the new flooring will be adhered, remove any wax, finish, or other substance that might prevent bonding.

    Planks/tiles can be cut using a sharp utility knife and a square. Score the surface of the plank/tile with the knife and snap the plank/tile at the score line. A tile cutter or powered saw can also be used. All installations that will be subject to rolling loads must be glued to the substrate. Rolling loads include but are not limited to wheel chairs, beds, carts, etc.
