Installation Instructions, Care and Maintenance Guide

Printable Version

Thank you very much for selecting Green World Industries hardwood flooring. We sincerely hope that your new environment will bring you the warmth, comfort and beauty that only genuine wood can provide. It is important to read ALL of the following installation, care and maintenance, and warranty instructions PRIOR to installation. Adherence to Green World’s installation, care and maintenance, and warranty is necessary to ensure that you will get the full benefit of your flooring for years to come.


Our engineered hardwood floors are acceptable for glue down, nail down, staple. A floating installation is accepted if the product is at least 5” wide and ½” thick. Out products offered are our Acacia, Hickory, Oak and Birch species. We recommend that the installer follow all installation guidelines as set forth by the National Wood Flooring Association (NWFA) for all phases of the installation.


Color Variation

Wood is a natural product and will vary in color, tone and grain from tree to tree and from plank to plank. For the best visual effect, shuffle planks from several cartons. Our floors are manufactured in accordance with accepted industry standards, which permit a natural or manufacturing defect tolerance, not to exceed 5%. Green World Industries cannot guarantee against color variations within a floor, or variations between samples and the installed floor.

The installer MUST perform a detailed product quality inspection. Material must be inspected for quality, quantity, species and color prior to installation. Ensure adequate lighting for proper inspection. If the material is not acceptable, do not install it, and contact the seller immediately. Green World Industries will exchange the material in a timely fashion. Installation indicates acceptance. If a defective board is installed, Green World Industries will not pay the cost of labor for repair or replacement of defect.

Acclimation and Suitability*

As relative humidity varies in different parts of the country, acclimation of the flooring prior to installation is the most important precaution to take in order to ensure a successful installation. Proper acclimation is necessary to adapt the moisture content of the flooring to the conditions of your environment.

Room temperature and humidity of installation area should be consistent with normal, year-round living conditions for at least one week before installation of flooring. A consistent room temperature of 60 to 70 degrees Fahrenheit and humidity range of 40-60% are recommended.

Our floors must be acclimated for a minimum of 72 hours prior to installation. Our product needs to be placed on the job site, under controlled temperature, moisture and mechanical ventilation conditions. (Please refer to NWFA guidelines.) The wood should be placed in the environment, unopened, but not directly on the floor to be installed. If placed in the area to be installed, raise product at least 4 inches off of floor to allow air flow.

*Responsibility for the suitability of Green World Industries flooring and accompanying products for each individual installation cannot be assumed by Green World Industries, since Green World Industries has no control over the installer’s proper application.

In addition to acclimation requirements, homeowners need to understand conditions in their part of the country, such as:

Seasons: Heating and Non-Heating

Heating season (Dry)—A humidifier is recommended to prevent excess shrinkage in wood floors due to low humidity levels. Wood stoves and electric heat, in particular, tend to create very dry conditions.

Non-Heating Season (Humid, Wet)—Proper humidity levels can be maintained by use of an air conditioner, dehumidifier, or by turning on your heating system periodically during the summer months. Avoid excessive exposure to water from tracking during periods of inclement weather. Do not obstruct in any way the expansion joint around the perimeter of your floor.

Subfloor Inspection and Preparation

Hardwood flooring should be one of the last items installed for any new construction or remodel project. All work involving water or moisture should be completed before hardwood flooring installations. Wood flooring may not be acceptable for full bathroom installations because of moisture associated with these areas.

It is the responsibility of the installer to determine that the job-site environment and subfloors meet or exceed all applicable standards and recommendations of the construction and materials industries.


The quality of your floor installation is dependent on quality and preparation of the subfloor. Acceptable subfloor types with tips to prepare are below:

Subfloor must be:


These are most of the tools needed for installation:

For nail down or staple down installations, you will also need an air stapler/nailer compatible with the profile of the flooring material. 1 ½” to 2: nail, cleat or staple that is compatible with the profile of the flooring material.
For glue down installations, you need an approved floor adhesive and trowel.
For floating installations use white wood glue.
See your flooring retailer for approved adhesives.

Caution: By not using the proper tools, “puckering” may result on the face of the plank. Green World Industries is not responsible for problems caused by the use of improper tools. See your distributor for tool recommendations and use.
Note: Never strike the plank edges directly with a hammer—always use a wooden block to protect the edges of the boards.


Layout should be designed to save labor and materials, as well as to enhance the appearance of the floor. Lay the floor so that the end joints are staggered at least 8 inches. Staggered or irregular joints mean less material waste and a better overall appearance. Plan the layout so that the last row of flooring (which usually needs to be cut lengthwise) is not too narrow. In some cases, it may be necessary to cut the first row as well as the last row. Allow 3/8” expansion space along all walls. Flooring should be laid at right angle to the floor joint and, if possible, in the directions of the longest dimension of the room. Use wood or plastic spaces during installation to maintain this 3/8” expansion space. Work from several boxes and “dry lay” the floor before permanently laying the floor for a more harmonious pattern. Remember, it is the installers’ responsibility to determine the expectations of what the finished floor will look like with the end user first and then to cull out pieces that do not meet those expectations.

Begin installation next to an outside wall. This is usually the straightest and best reference for establishing a straight working line. Establish this line by measuring an equal distance from the wall at both ends and snapping a chalk line. The distance you measure from the wall should be the width of a plank plus about 3/8” for expansion space. You may make a straight working line if the wall is out of straight.

You may want to dry lay a few rows, (no glue or nails). Before starting to confirm your layout decision and working line. When laying flooring, stagger end joints from row to row by at least 8”. When you begin cutting thee last plank in a row to fit, you can use the cut-off end to begin the next row. If cut-off end is 8” in length or less, discard and instead cut a new plank at a random length and use it to start the next row. Always begin each row from the same side of the room.

To draw planks together, always use a tapping block (a short piece of flooring), as tapping the flooring itself will result in edge damage. For best results, flip the tapping block upside down and use groove edge to top the tongue edge of the plank being installed. Fit end joints tightly together before tapping long edges together. When near a wall, you can use a pry bar to pry close the side and end joints. Take care not to damage edge of flooring. For glue down and floating applications, use 3M® Blue Tape to hold any pieces which might have side bow and need to be held straight and tight until the adhesive set up. DO NOT ADHERE TAPE OF ANY KIND TO OIL FNISHED FLOORS.


Make sure subfloor is tested for moisture content first and is properly prepared.
On concrete subfloors, which are on or above grade (ground level), always assume the worst even if they measure dry. We recommend taking the following installation steps to ensure a trouble-free installation.

Use flooring adhesive recommended by your retailer. Use of another manufacturer’s adhesive may result in failure and void warranty. Follow adhesive manufacturer’s instructions for proper trowel size, minimum temperature, adhesive set time and open times before beginning installation of flooring.

Once the spread of adhesive has setup sufficiently per adhesive manufacturer’s instructions, lay the first row of flooring with groove facing the wall, and continue laying flooring. Always check your working lines to be sure the floor is still aligned. Use tapping block to fit planks together, but be careful not to let installed floor move on the wet adhesive while you are working. Always leave at least a 3/8” expansion space between flooring and vertical objects (such as pipes and cabinets). Use wood or plastic spacers during installation to maintain this expansion space. Remember to stagger end joints from row to row at least 8” apart.

When first section is finished, continue to spread adhesive and lay flooring section by section until installation is complete. Use a damp cloth to IMMEDIATELY REMOVE ANY ADHESIVE that gets on the flooring surface. If adhesive cannot be completely removed with a damp cloth, use the manufacturer’s recommended adhesive remover. Never let flooring adhesive dry completely on the finished surface.

Walk each section of flooring in order to make sure it is well bonded to the subfloor with the adhesive working time. Flooring planks on the perimeter of the room may require weight on them until adhesive cures enough to hold them down.


Make sure subfloor is tested for moisture content first and is properly prepared.
Use an air stapler/nailer compatible with the profile of the flooring material (or) a stapler/nailer of your choice. Test on a sample to make sure that stapling/nailing will not cause dimpling (localized raised edges) in the finished floor. (Note: be sure to look at the face of the installed flooring at a low angle from a distance to see if dimpling is occurring as it is hard to see when directly above the floor.) If dimpling does occur, STOP and adjust the stapler/nailer shoe and and angle/place of staple entry in order to avoid it. Green World Industries is not responsible for dimpling.

For the first and second rows: lay first plank inside chalk line with grooved edge toward wall. Install entire first row in the same manner. Always leave at least a 3/8’’ expansion space between flooring and vertical objects (such as pipes and cabinets). Use wood or plastic spacers during installation to maintain this expansion space. In order to affix the first rows, as it is difficult to get the nail gun in place next to the wall, you may wish to set these rows in mastic and glue them down rather than face nailing them and leaving unsightly nail holes which much be filled with putty to match the wood floor.

After gluing down these starting rows with manufacturer’s recommended adhesive, set weight on top of these rows and allow them to set before commencing stapling/nailing the additional rows, as nailing the adjacent rows may cause the starting rows to subsequently move. Make sure they starting rows are straight and drawn tight.

Subsequent rows: Lay by using floor nailer/stapler to blind-nail top inside edge of tongue at a 45 degree angle. Nail each board every 8” and within 2” of each end. Remember to stagger end joints from row to row at least 8” apart and using a tapping block to fit boards together. It may be necessary to face-nail in doorways or tight areas where the nailer/stapler can’t fit, (or glue down in these areas and weight them while the mastic sets). The last two rows will need to be face-nailed, (or glued down), in the same manner as the first two rows.

Always make sure to visually check the installed floor as you go to ensure that the stapling/nailing is not causing dimpling on the face.


Make sure subfloor is tested for moisture content first and is properly prepared.
Floating installation method should only be used on engineered floors measuring at least 5” in plank width.
A 1/8” thick pad and polyfilm is required.
Laying polyfilm: Lay at least a 6-mil polyfilm with seams overlapped 8”. Fasten seams every 18-24” with duct tape. Run the outside edges of film up perimeter of each wall 4”. Trim after flooring installation is complete.
Laying pad: Lay underlayment by butting edges, not overlapping. Tape full length of the seam with duct tape. Leave ½” space between pad and all walls and permanent vertical fixtures.

Installing the floor: Start first row with groove toward wall. Glue end joints of first row by applying a small but continuous bead tongue and groove adhesive or PVAC glue to bottom side of the groove. Always leave at least a 3/8’’ expansion space between flooring and vertical objects (such as pipes and cabinets). Use wood or plastic spacers during installation to maintain this expansion space. Lay subsequent rows of flooring by applying glue to side and end joints and fitting planks together with a tapping block. Remember to stagger end joints from row to row at least 8” apart.

Clean up any adhesive that is on the face of the floor by using a damp rag—DO NOT allow adhesive to dry on the flooring face as it is difficult to remove without damaging the finish.


This type of installation requires a specific construction of the plywood subfloor and the installer for such must be familiar with the NWFA recommendations.
