ENVEE Tile and Plank Installation Instructions
Before you begin the installation, inspect the flooring material for any obvious defects. Ensure you have the correct color, pattern, quantity, and that all the material is of the same production number. Beginning the installation means that you have accepted the conditions.
It is essential that all subfloors be rigid, smooth, flat, level, permanently dry, and free of all foreign materials. Subfloor preparation should be done with the permanent HVAC set at a minimum of 650F (180C).
Wood floors should be double construction with a minimum thickness of 1”. The floor must be rigid, free from movement and have at least 18” of well-ventilated air space below. Envee should not be installed over wooden subfloors built on sleepers over, on grade, or below grade concrete floors unless specific design has been undertaken to eliminate the chance of failure due to the excessive moisture vapor emissions from the concrete.
Underlayment panels are used to correct deficiencies in the subfloor and to provide a smooth, sound surface on which to adhere the resilient flooring. APA underlayment grade plywood, minimum ¼” thickness, with fully sanded face is the preferred panel. Underlayment panels such as Multiply, Tee-Ply and Ulay are recommended. The underlayment must be free of any foreign material that may cause staining, such as patching compounds, sealers, inks, solvents, etc.
The underlayment should be installed with dispersion type staples placed every 4 to 6 inches in the field and every 2 to 3 inches along the seams. Sanding is a preferred method for smoothing joints.
The American Plywood Association offers other acceptable guidelines for proper wooden subfloor installation. The above mentioned is not considered the only procedure for a successful installation. Always install and fasten underlayment panels according to the manufacturers’ recommendations.
There are certain types of subfloors and underlayment that through years of experience are known to be prone to failure and are therefore NOT recommended underlayments for resilient floor coverings.
Tempered hardboard and Luan board are not suitable to install Envee over. In some cases permanent staining has occurred from chemicals used in the construction of Luan board. This is also true when using pressure treated or fire retardant wood. Regardless of which underlayment is used, failures in the performance of Envee due to the underlayment are not covered by Advanta’s warranty.
Strip Wood/Plank Flooring
Due to expansion and contraction of the boards during seasonal changes, Advanta recommends the use of ¼” or thicker underlayment panels be installed over these types of floors.
Concrete floors should be prepared according to ASTM F-710, Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring.
It is essential that a permanent, effective moisture vapor retarder with a permeance of 0.1y, be installed under all on- or below-grade concrete floors. The water vapor retarder (vapor barrier) should be installed directly below the slab.
Floors shall be smooth, rigid, flat, level, permanently dry, clean and free of all foreign material. such as old adhesive residue. Imperfections such as chips, spalls, cracks and/or corrective leveling shall be repaired with cementitious based patching and/or underlayment materials. The surface of the concrete must be flat to within 3/16 in. in 10 feet..
Expansion joints, saw cuts, control joints
Expansion joints in the concrete are designed to allow for the expansion and contraction of the concrete. If the floor coverings are installed over the expansion joints, it more than likely will cause gapping or buckling of the flooring material. Therefore, flooring products should not be installed over expansion joints, an expansion joint cover designed for use with resilient floorings should be used.
Isolation, construction and control (saw cut) joints may be successfully patched once the concrete is thoroughly cured, dry and climatized. If any movement occurs in the concrete it may also cause the patching material to telegraph.
There are many brands available but basically there are two types of patching materials for the use of smoothing and patching subfloor irregularities. One type is referred to as calcium sulfate/plaster/gypsum base compounds. This type of patch may harbor and promote mildew growth, have low indentation resistance and poor bond and adhesion strength.
The second type is a cement based compound usually with polymer additive. This type of patch will not promote mildew growth; have much higher psi strength and better adhesion properties to the subfloor. Advanta Flooring recommends only the use of cementitious base patching and leveling compounds.
Only use the highest quality materials. Many failures have been directly attributed to the use of gypsum based toppings, leveling and patching compounds because of poor indentation resistance, poor resistance to mold and mildew and separation of the product within itself.
Regardless of which patching or leveling compound is used, any failures in the performance of the compound or Envee tiles due to the compound is the responsibility of the compound manufacturer and installer, not with Advanta Flooring.
Old Adhesive Residue
If a residue is asphaltic (cut-back) or other type of adhesive is present, it must be dealt with in one of two ways:
1. It may be mechanically removed such as: bead blasting or diamond grinding.
2. A self-leveling cementitious underlayment may be applied over it. Check with the underlayment manufacturer for suitability, application instructions and warranties.
Never use solvents or citrus adhesive removers to remove old adhesive residue. Residue left within the subfloor will affect the new adhesive and the new floor covering.
Warning regarding complete adhesive removal: some solvent based ‘cut-back’ Asphaltic adhesives may contain asbestos fibers that are not readily identifiable. Do not use power devices, which create asbestos dust in removing these adhesives. The inhalation of asbestos dust may cause asbestosis or other serious bodily harm. Smoking greatly increases the risk of serious bodily harm.
Existing Resilient Floors
Envee may be installed over a single layer of resilient flooring such as VAT, VCT and sheet vinyl.
Note: The responsibility of determining if the existing flooring or subfloor is suitable to be installed over rests solely with the installer and flooring contractor. Installations over existing resilient flooring may be more susceptible to indentation, moisture vapor emission problems and there is always a possibility the existing flooring may telegraph through.
(Epoxy, Polymeric, Seamless)
Envee tiles may be installed over most poured floors provided they meet the following conditions:
1. Concrete floors that are on, above and below grade – Conduct moisture tests according to ASTM F-1869, Calcium Chloride Moisture Vapor Emission and ASTM F-2170, In-Situ Relative Humidity of the Concrete. Conduct one test for every 1000 sq. ft. of flooring. The test results should not exceed 5 pounds per 1000 square feet per 24 hours for the calcium chloride test and 85% for the in-situ relative humidity. The existing flooring and adhesive must be removed where the test is conducted.
2. It must be totally cured and well bonded to the concrete. It must be free of any residual solvents and petroleum derivatives.
3. The texture must be smooth. Sand or wet stone the surface to remove any grit and texture.
The responsibility of determining if the existing flooring is suitable to be installed over rests solely with the installer and the flooring contractor.
Do not sand, dry sweep, dry scrape, saw, bead-blast or mechanically chip or pulverize existing resilient flooring, backing, lining felt or asphaltic ‘cut-back’ adhesives. These products may contain either asbestos fibers or crystalline silica. Avoid creating dust. Inhalation of such dust is a cancer and respiratory tract hazard. Smoking by individuals exposed to asbestos fibers greatly increases the risk of serious bodily harm. Unless positively certain that the product is a non-asbestos containing material, you must presume it contains asbestos. Regulations may require that the material be tested to determine asbestos content. The RFCI’S Recommended work practices for removal of resilient floor coverings are a defined set of instructions which should be followed if you must remove existing resilient floor covering structures.
Radiant Heated Floors
Envee tile may be installed over radiant heated floors provided the operating temperature does not exceed 85°F. The room temperature must be maintained at a minimum of 65°F for 48 hours prior to, during and after installation, after which the temperature of the radiant heating system can be increased. When raising the floor temperature, do so gradually so that the substrate and the flooring material can adapt to the temperature change together. A rapid change could result in bonding problems. For more information, contact Advanta Technical Services.
Moisture Testing –
It is essential that moisture tests be taken on all concrete floors regardless of age or grade level with a minimum of three tests for the first 1000 square feet. The test should be conducted according to ASTM F1869, Calcium Chloride Moisture Emission Test, and ASTM F2170, In-Situ Relative Humidity of the Concrete. One test should be conducted for every 1000 square feet of flooring. The test should be conducted around the perimeter of the room, near columns and where moisture may be evident. The results of F1869 Calcium Chloride moisture vapor emissions from the concrete shall not exceed 5.0 lbs. per 1000 sq. ft. in 24 hrs. for all installations. For the most accurate results, the weight of the calcium chloride dish should be made on the job site at the start and end of each test. The results of F2170 In-Situ Relative Humidity shall not exceed 85%. A diagram of the area showing the location and results of each test should be submitted to the architect, general contractor or end user. If the test results exceed the limitations, the installation should not proceed until the problem has been corrected.
Note: It may not be the floor installer’s responsibility to conduct the test. It is, however, the floor covering installer’s responsibility to make sure these tests have been conducted and that the results are acceptable prior to installing the floor covering.
When moisture tests are conducted it indicates the conditions only at the time of the test. The flooring contractor cannot be held responsible if moisture appears in the future, causing a failure.
Flooring shall be stored in a clean, dry environment, protected from the elements. Storage temperature should be between 65° and 85°F.
Store cartons on a smooth, level surface. Stack cartons squarely. Do not stack more than 10 cartons high. Do not store tiles and planks on their edges. Do not drop cartons. Do not double stack pallets. Storing tile at high temperatures and on uneven surfaces may cause a permanent distortion of the material.
All areas should be fully enclosed, weather-tight with the permanent HVAC system in operation. The temperature should be maintained at a minimum of 65°F (18oC) and a maximum of 85°F (29oC) for 48 hours prior to, during, and 48 hours after installation. Thereafter, maintain a room temperature between 55°F (13°C) and 85°F (29°C).
Proper layout will prevent narrow pieces along the wall. For plank installations lay the long dimension of the plank parallel with the long dimension of the room. Plank ends should be staggered randomly. Keep end joints at least 4” apart. Start each row with planks of varying lengths. Usually the left over piece from one row can be used as the starter piece on the next row of planks.
- Ensure the subfloor is clean and dust free, particularly around the perimeter of the room
- Measure the room to determine the center line, adjust that center line in either direction to give a balanced width of plank/tile on each side of the room. Determine the distance from your starting wall where the first row of planks/tile will start and snap a chalk line along the starting wall.
- If the first row is less than the full width of the plank/tile, or if the wall is not straight, cut the first row to the needed size leaving a 1/8” gap between the tile and the wall.
- Lay the first row of planks/tile along the chalk line to ensure all pieces are cut to the width and length needed.
- Once everything the first row is fit in, pull the planks/tile away from the wall about 1 foot.
- Install the Envee double face tape around the entire perimeter of the room, around cabinets and doorways. Do not remove the paper.
- At the starting wall, remove the paper from the double face tape. Ensure the chalk line is intact and visible.
- Starting in the corner, install the first row of planks/tile along the chalk line and into the double face tape. The first row must be straight as it is the foundation for the rest of the installation.
- For planks start the second row with a cut piece of approximately 2’ in order to stagger the end joints.
- Remove the paper from the double face tape as you go.
- Lay each plank/tile tight to each other.
- For planks use the balance of the last cut from the previous row as the beginning piece for the next row.
- Upon completion install base shoe to cover gap around the wall.
