Owner/Installer Responsibility

The owner is advised to be at home during the installation for consultation/direction.  The owner and installer should discuss installation and layout to maximize satisfaction.  If this is not possible, consultation should be done prior to installation.

The owner/installer assumes all responsibility for product quality of completed installation.


Flooring to be installed in one large area should be purchased at the same time.  Product purchased at a later time than the first purchase may vary beyond your expectations.

This product is manufactured according to strict quality standards.  In the event that defects are discovered in the field, the industry standards permit a defect tolerance not to exceed 5%.  Order an additional 5% (10% extra for diagonal installations) for cutting wastage and plank replacement when the floor is in service.

During installation, inspect the planks continuously.  Defects that can be seen from a standing position should be cut off or held out.  Installing defective planks implies acceptance


Job Site Condition

Prior to installation, the installer must ensure that at the time of installation, the job site conditions including subfloor/substrate, ambient temperature and relative humidity, and all impacting variables will not negatively affect floor.  The Six Plus will decline responsibility for damages associated with improper installation or poor site conditions.

Storage and Conditions

Do not store flooring in uncontrolled environmental conditions.  For example, garages and exterior patios are not acceptable areas to store

flooring.  Handle and unload flooring with care and store within the environmentally controlled site in which it is expected to perform.  Flooring stored on concrete slab should be elevated at least four inches to allow air circulation under cartons.

Existing Home

Existing home should have a consistent room temperature of 60°F-75°F and relative humidity (RH) of 35%-55%.  Continual extreme deviation from these conditions will affect the dimensions of flooring.  During heating season, humidity may be much lower than the acceptable range.  During the heating season, a humidifier is recommended to prevent excess shrinkage in flooring due to low humidity levels.  During the nonheating season, humidity levels can be maintained by using an air conditioner, dehumidifier, or by turning on your heating system periodically.

New Construction or Remodel

All work involving water, such as pouring basement concrete floors, drywall and plasterwork, plumbing, etc. must be completed well in advance of the floor delivery.  Ensure that the building is enclosed.  Where building codes allow, permanent heating and/or air conditioning systems should be operating at least five days preceding installation to promote proper acclimation and should be maintained during and after installation.  If it is not possible for the permanent heating and/or air conditioning system to be operating before, during and after installation, a temporary heating and/or dehumidification system that simulate normal living (occupied) conditions can enable the installation to proceed until the permanent heating and/or air conditioning system is fully operational.

Your job site should have a consistent temperature of 60°F-75°F and relative humidity (RH) of 35%-55% which should be maintained continuously thereafter.

Basements and Crawl Spaces

Concrete slab or ground must be dry.  The ground in the crawl spaces must be completely covered using 6 mil black polyethylene.  Crawl space clearance between the earth and underside of joists should be no less than 18 inches and the perimeter vent area should be equal to 1.5% of the total square footage of the crawl space or as mandated by code.

Concrete Subfloor Requirements

It must have minimum rated strength of 3000 psi.

It must be level to within 1/8” in a 6 foot span or 3/16” in a 10 foot span; no bumps or low spots.  High spots can be removed by grinding; Gaps greater than 5/32” wide and 1/16” and depressions should be filled with patching compound formulated for use in floor installation.   It must be clean; no construction debris, soil, mud and any other objects on or adhering to the floor; if necessary, scrape and sweep away before the installation; no protrusions of nails, debris, metals should remain.

New concrete slab must cure for at least 60 days.  It must have a minimum 10 mil polyethylene sheet between the ground and the concrete. It must meet concrete moisture requirement below.

It must be free from moisture related conditions which can damage the installed flooring.

Light Weight Concrete

It is concrete which rated strength is less than 3000 psi.

Perform a quick check by drawing a nail across the top; if it leaves indentation, it is probably light concrete.

For glue-down application, the concrete must possess shear strength greater than the glue.  If concrete rated psi is unknown, contact the adhesive manufacturer for guidance.

Concrete Moisture

All concrete subfloors should be tested for moisture content and the results documented.  Visual checks are not reliable.  Perform tests at locations around exterior doorways, near walls containing plumbing, near foundation walls and in the center of the room.  Minimum sample size is 3 samples per 1000 square feet of area and one test for every additional 1000 square feet thereafter.

Its moisture content should meet one of the following criteria below:

  • 5% when tested using Tramex Concrete Moisture Encounter
  • Less than 3 pounds per 1000 square feet per 24 hours when using Calcium Chloride test (ASTM F 1869)
  • 75% when using Relative Humidity Testing (ASTM F-2170).

Please note:  Concrete moisture content may be acceptable the time of the test.  These tests do not guarantee a perpetual “dry” concrete slab.  The concrete slab moisture content can vary at other times of the year.  We are not responsible for moisture related damage to installed flooring.

Wood Subfloor Requirements

It must be clean; no presence of construction debris, soil, mud and any other objects on or adhering to the floor; no protrusions of nails, debris, metals should remain.  If necessary, scrape and sweep the subfloor before the installation.

It must be structurally sound and stable; no movements or squeaks; no loose panels or loose nails; no signs of ply de-lamination or other damages.  Repair all shortcomings before installation.

It must be flat; no visible bumps or low spots; the subfloor should be flat to within 1/8” in 6 feet span or 3/16” in 10 feet.

It must be dry.

Plywood or Oriented Strand Board (OSB) Specifications

On truss/joist spacing of 16” (406mm) O/C or less, the industry standard for single-panel subflooring is minimum 5/8” (19/32”, 15.1 mm) CD Exposure 1 plywood subfloor panels (CD Exposure 1) or 23/32” OSB Exposure 1 subfloor panels, 4’ x 8′ sheets.  Expansion gap between panels should be 1/8” (3 mm).  When subfloor panels spacing is inadequate, cut in the required spacing with a circular saw if the panels are not tongued and grooved. Do not cut in expansion space on joined tongue and groove of panels.

Particle Board or Fiber Board

Only for floating installation.

Existing Floors

Installation over existing floor requires the installer to consider potential issues related to moisture damage, adhesive failure and fastener failure.  Contact the adhesive and fastener manufacturers respectively for their specific instructions, recommendations and requirements.

Acceptable floor coverings include: solid hardwood, linoleum, terrazzo, ceramic tile and other “moisture sealing floors.”

Unacceptable floor coverings include: carpet, needle punch felt, edge glued linoleum and other “moisture absorbing flooring.”

Radiant Heated Subfloor

This product can be installed over radiant heated subfloor.  Heating system must be in operation at least for 7 days prior to installation.  Decrease temperature before installation.  Increase temperature gradually after installation.  Operating surface temperature must be less than 84°F.  Contact heater manufacturer for specific installation instruction.

Moisture Barrier and Moisture Retarder

Concrete Subfloor: For floating installation, use 6 mil polyethylene film or other means with equivalent permeability.   Overlap the edge seams and tape it together.  Extend moisture barrier up to the wall about 1 inch high.  When installed on above grade concrete and the moisture content meets standards for concrete moisture, a moisture barrier is not required.  For direct glue installation, use a moisture barrier if moisture level exceeds requirement (see Concrete Moisture section above). Wood Subfloor:  Not required.

Sound Control Underlayment

It is optional. Check with sound control manufacturer for application guidelines.  Generally, the less compressive underlayment is preferred.

Expansion Gap

Required gap width range is 5/16” to 3/8”.  It is required around the perimeter of the floor and between floor and all vertical obstructions.  Do not place permanently installed structures such as kitchen counter/cabinet on the installed floor.

Wet Areas

This product can be installed in kitchens, mud rooms, powder rooms, bathrooms and laundry rooms. Do not install in saunas, swimming pool areas and other similar extreme wet areas. Fill all expansion gaps with water repellant caulk.


Glue specifically designed for gluing PVC, LVT and other vinyl based flooring.

Tools and Materials Basics:

Utility knife, chalk line, chalk, pencil, T-square, tape measure, spacers, broom, hand saw or jamb saw, eye protection, work gloves.

Additional Supplies for Glue-Down Method:

Flooring adhesive • Trowels • Adhesive remover for selected adhesive • Clean rags • Weight roller • 3M Blue tape


Bond Failure

Bond failure is NOT flooring product defect.  Most installation failures, including bond failure, result from jobsite moisture.  Do not unpack or deliver flooring to the jobsite until moisture problems are corrected.  Read adhesive manufacturer’s instruction carefully. Not following the adhesive manufacturer’s recommendations can lead to installation failure or product damage and will void your warranty.

Glue Spots on Face of Finished Floor

Adhesive can damage the floor’s finish, especially when it has dried.  It is extremely important to take precautionary steps NOT to leave finger prints or footprints marks on the face of the board.  If glue comes in contact with the face of the board, remove immediately with the adhesive remover recommended by the adhesive manufacturer.  Use clean towels, changing frequently to prevent haze and adhesive residue.  If the spot removal damages the appearance of the boards, replace the board.

Helpful Pointers

General Tips

  • Make sure your work area is well lit. Good visibility ensures that color is consistent and that visually defective planks are detected and removed.
  • Preferred minimum length of the first and last plank is 12”. The remainder of the last plank can be used as a starter board on the following rows.
  • Using a shorter piece at undercut door jams will help when fitting flooring in place.

Glue-Down Installation Tips

  • ALWAYS REFER TO THE SPECIFIC INSTRUCTIONS ON THE FLOORING ADHESIVE LABEL. The information given here is for typical installation.  Adjust it according to adhesive manufacturer’s instruction.
  • Dry-lay means the glue has to set before placing floor planks in it. Wet-lay means the glue does not need to set before placing floor on it.
  • Use trowel design as specified by adhesive manufacturer.
  • Continuously check the transfer of adhesive THROUGHOUT the installation process. If the adhesive no longer transfers to the back of the flooring material, it must be removed and new adhesive applied.
  • Work your way out of the room.
  • After the installation is completed, keep the floor free from daily foot traffic for a minimum of 24 hours to allow adhesive to properly cure.

Cutting the Last Row to Width

  • Most often the entire length of the last row will need to be cut so that it is narrow enough to fit the remaining space.
  • Measure the distance between the floor face edge (exclude the tongue) to the wall. Subtract 5/16” – 3/8” from this measurement for expansion gap.  Draw a line.  Cut through the line.  Discard the excess piece.  Proceed with installation.

Floating Installation


Step 1 – Pre-install Activities

  • Ensure that the width of first and last row is not less than 2 inches wide. Measure the distance of room in the direction of the width of the plank. Divide the distance by  the width of the plank.  Multiply the number beyond the decimal point of the by the width of the plank.  This is the width of the last plank.  If it is less than 2 inches, you must cut the first plank.  Determine the width of the first and the last row by adding the calculated width of the last plank to the width of a whole plank.  Divide this number by two.  Subtract the expansion gap from the result.  The result is the width of the first and last row.
  • Rack up planks from several boxes.
  • Ensure that end joints are staggered at least 12” between the rows.
  • Inspect product for defects. If material is questionable, contact the retailer immediately.  Do not proceed with installation

Step 2

  • Cut off the unsupported tongue of the first row so that a clean, solid edge is towards the wall.
  • If the first row of floor panels had already been trimmed in width to meet minimum requirement, there is no need to trim it again.

Step 3

  • Install the product from left to right, across the room.
  • Place the floor panel with the locking groove facing the room.
  • Ensure there is expansion gaps. Between floor and the wall and all vertical fixtures during installation.

Step 4

  • Place the short side tongue of the next floor panel at an angle into the short side groove of the first one and fold down.
  • Continue with the next floor panels in the same way.

Step 5

  • Place the final floor panel face up, locking groove long side towards the wall, and the short end tongue positioned 3/16 to 5/16 inch from the wall.
  • Mark the place where the floor panel is to be cut.
  • Make a cut in the floor panel on the decor side with a utility knife. Use the snap method to break the unneeded part off.

Step 6

  • Stagger the end joints between rows at a minimum 12 inches.
  • If you can, use the cut piece of floor panel from the previous row. If not suitable, take a new floor panel and cut it in half.
  • Place the floor panel at a low angle and insert the long side tongue into the locking groove of the floor panel in the previous row.
  • Fold the floor panel gently down.

Step 7

  • Ensure that the long side tongue is positioned on the locking strip of the previous row.

Step 8

  • Using gentle force and at an angle, you gradually, from left to right, push the long side tongue into the locking groove of the previous row.
  • You may need to lift the floor panel to the left of it slightly to allow for the ‘sliding action’.
  • Complete the whole row in the same way.


Expansion gaps around pipes.

  • Measure the diameter of the pipes and mark the position on the floorboard. There should be a 3/16 to 5/16 inch expansion gaps between the floor panel and the pipe or other vertical structures.
  • Cut out the holes.

Door frames may have to be undercut.

  • Use a floor panel as a guide as to how much to saw.
  • Put the floor panel faced down as a guide.
  • Saw off the bottom of the door frame to allow the floor panel to slide under it.              


Glue Down Installation


Installation Overview


  • The main difference between floating and glue down method is the additional spreading of the glue on the subfloor.
  • Do not spread glue on more area than you can work with.
  • An area the size of two installed rows is a good starting area.
  • The steps described in the floating installation are the same for glue down installation.
  • Always follow adhesive manufacturer’s instruction.


Installation Procedure


  • Spread the glue width of two initial starter rows.
  • Install the first row of planks.
  • Install the second row. Ensure you are locking the edges.
  • Spread another section of glue.
  • Install another two rows.
  • Repeat spreading glue/install planks cycle until all flooring has been installed.
