SUPERCore Installation Instructions

SUPERCORE GENERAL INFORMATION

These installation specifications are for SUPERCore. All recommendations are based on the most recent available information. All instructions and recommendations must be followed for satisfactory installation. You may also visit WeShipFloors.com.com or call us at 844-3456-6711 for recent updates.

• Although acclimation is not specifically required, best installation practice recommends that the product be installed close to intended occupied service temperature, generally a target of 70° F (21°C), but at least between 55°F (13°C) and 100°F (38°C).

• SUPERCore is recommended for three season rooms and seasonal homes over concrete substrate. Installer must provide at least 5/8” (16mm) expansion.

• SUPERCore is not recommended where the floor might experience temperature extremes beyond -30°F (-34°C) or greater than 155° F (68°C). Occupied use temperature range is assumed to be between 55° (13°C) and 100° F (38°C).

• SUPERCore can be installed up to 50’ x 50’ (15.2 m X 15.2 m) or total of 2500 sq. ft. (232.3 sq m) with a ¼” (6.4mm) expansion. Larger areas must provide a 5/8” (16mm) expansion up to 100’ x 100’ (30.4 m X 30.4 m).

• Install SUPERCore only after the jobsite has been cleaned and cleared of other trade apparatus that may damage a finished installation.

• Mix and install product from several different cartons to achieve desirable plank variation.

• All subfloor/underlayment patching must be done with a non-shrinking, water resistant, high quality Portland cement patching compound.

• Structural subfloor requirements must meet local building codes as well as WeShipFloors.com criteria. For concrete subfloors, conformance to ASTM F 710 and for panel underlayment’s conformance to ASTM F 1482.

• SUPERCore is designed to be installed as a Unilin- Unipush drop and lock locking system.

SUBFLOOR INFORMATION

• Careful and correct preparation of the subfloor is a major part of a satisfactory installation. SUPERCore is designed using a “floating floor” installation method. Although SUPERCore will bridge minor floor imperfections and gaps; heavy roughness or unevenness in the subfloor may telegraph through the new floor covering.

• All subfloors should be flat to within 3/16” (4.8 mm) in 10’ (3048 mm) and 1/32” (0.8 mm) in 12” (305 mm).

• Never install SUPERCore products over residual asphalt-type (cut back) adhesive. Residual cut back adhesive should be completely removed and covered with high quality 4 to 6 mil plastic sheeting.

• SUPERCore already had an attached pad, do not use additional underlayment.  4 to 6mil plastic sheeting can be used as an additional moisture barrier. 

Wood Subfloors

• All wood floors must be suspended at least 18” (457.2 mm) above the ground. It is important to provide adequate cross-ventilation. Cover the ground surface of a crawl space with a suitable vapor barrier. Wood subfloors directly on concrete or installed over sleeper construction are not satisfactory for installation.

• SUPERCore can be installed over many wood substrates that are not suitable for fully adhered products, if they are smooth, flat, structurally sound and free of deflection, including particleboard, chipboard, flake board, OSB. Caution: Damage may occur on wood panel subfloors during construction. The suitability of these floors is the responsibility of the installer.

• If the surface of the wood subfloor is not smooth, a 1/4” (6.4mm) wood underlayment panel should be installed over the subfloor. Any panels selected as an underlayment must meet the following criteria:

  • Be dimensionally stable
  • Have a smooth, fully sanded face so the graining or texturing will not show through
  • Be resistant to both static and impact indentation
  • Be free of any surface components that may cause staining such as plastic fillers, marking inks, sealers, etc
  • Be of uniform density, porosity and thickness
  • Have a written warranty for suitability and performance from the panel manufacturer or have a history of proven performance

Concrete Subfloors

• Concrete subfloors must be dry, smooth, and free from dust, solvent, paint, wax, grease, oil, asphalt sealing compounds and other extraneous materials. The surface must be hard and dense and free from powder or flaking.

• Surface of the slab should be flat to within 3/16” (4.8 mm) in 10’ (3048 mm) and 1/32” (0.8 mm) in 12” (305 mm).

• New concrete slabs must be thoroughly dry (at least six weeks) and completely cured.

• All concrete slabs must be checked for moisture before installing material. Details for moisture testing can be found on our website. The final responsibility for determining if the concrete is dry enough for installation of the flooring lies with the floor covering installer. SUPERCore must never be installed where excessive moisture emissions may exist. In accordance with ASTM F1869 moisture emission from subfloor cannot exceed 8 lbs MVER (moisture vapor emission rate) per 1,000 sq. ft. per 24 hours as measured with the calcium chloride test or ASTM F 2170 In Situ Relative Humidity Test not to exceed 85%. WeShipFloors.com will not assume responsibility for floor covering failure due to hydrostatic pressure or excessive moisture vapor emission. New concrete slabs must be thoroughly dry (at least six weeks) and completely cured. Although the planks are not susceptible to damage from moisture, excessive subfloor moisture can be a breeding ground for mold, mildew and fungus. All of which can contribute to an unhealthy indoor environment. The Limited Warranties do not cover issues arising from flooding, leaking plumbing or appliances, water entering through sliding glass doors, presence of mold, discoloration from mold or fungi or similar conditions.

• Holes, grooves, expansion joints and other depressions must be filled with a high quality cementitious patching & leveling compound, troweled smooth and feathered even with the surrounding surface.

• Concrete floors with a hydronic radiant heating system are satisfactory, provided the temperature of the floor does not exceed 85°F at any point. Before installing the flooring, the heating system should be turned on to eliminate residual moisture. WeShipFloors.com does not recommend heated floor mats for SUPERCore.

Existing Floor Coverings

• SUPERCore can also be installed over most existing hard–surface floor coverings provided that the existing floor is well bonded and the surface is flat and smooth.
• Ceramic tile unevenness should be made smooth by applying an overlay such as cementitious patching or leveling compound grind down the high areas if needed.
• Existing floors should not be heavily cushioned and not exceed one layer in thickness, Do not install over carpet.
• Floor should be flat, smooth, dimensionally sound and free from deflection.

INSTALLATION

SUPERCore is designed to be installed as a “floating” floor. Do not secure the planks to the subfloor. Always undercut wood doorjambs. Check local building code for metal door jamb. If they cannot be cut, then proper expansion must be maintained around door jamb. Do not install cabinets or kitchen islands on top of SUPERCore. Use care when installing wall moldings and transition strips to not fasten through the product. SUPERCore is a drop and lock product.  Please see
illustration below on proper install technique.

Quick note about expansion

  • 3 season rooms and seasonal homes – 5/8” expansion
  • project less than 50’ x 50’ or (2500sf) – 3/8” expansion
  • project over 2500sf – 5/8” expansion

Fig 1. First plank, first row. Place a spacer of 3/8” thickness to the left and position the plank against the wall. Later, after 3 rows, you can easily position the flooring against the front wall with distances ≈ 3/8”

 

 

 

 

Fig 2. Second plank, first row- place this plank gently and tight to the short end of the first one.

 

 

 

 

 

Fig 3. Fold the panel down in a single action movement. During the fold down, make sure the panels are tight against each other. Afterwards press down or slightly tap down at the short end just installed till it clicks. No major force is required. ***DO NOT OVERLAP ENDJOINT*** Overlapping the end joint slightly can cause the lock to bend or break when tapping the lock together.

 

 

 

 

 

Fig 4. At the end of the first row, put a spacer 3/8” to the wall and measure the length of the last plank to fit.

 

 

 

 

 

 

Fig 5. Cut with a jig saw – hardwood face turned down to eliminate/reduce damage to the face panel. Or if cutting using a hand saw, chop saw or guillotine cutter, cut it with the hardwood visible face up. Then install it as previous plank.   A utility knife can also be used for straight cuts.  Score the face several passes using a speed square as a guide.  Then snap the flooring - like scoring and snapping drywall.

 

 

 

 

Fig 6. Starting the Second row the first plank should be a min length of 10”. Put a 3/8 spacer against the wall and measure the last piece. If it is shorter than 10” a new starter piece should be used. Insert the plank at an angle into the previous row and tap (on the long side) it in using a tapping block till flat.

 

 

Fig 7. General distances between short ends. Minimum distance between short ends of planks in parallel rows should not be less than 6”.

 

 

 

 

Fig 8a. Second plank, second row place the panel at an angle into the groove of the previous row making sure that the end of the panel is tight/flush to the short end of the previous panel.  *** DO NOT OVERLAP ENDJOINT*** Overlapping the end joint slightly can cause the lock to bend or break when tapping the lock together.

 

 

 

 

Fig 8b. Fold the panel down in a single action movement with a slight press to the left to the short end of the previous panel. Again, using the tapping block tap it against the long end into the previous row. During the fold down, make sure the panels are tight against each other

 

 

 

 

 

Fig 8c.  As the board drops to the floor, press or gently tap the top of the short end of the installed panel until it is locked. It is recommended that a soft face rubber mallet be used for tapping.  The product is properly locked when the two boards are flush across the top.  Finish installing this plank by tapping it with a tapping block on the long side to ensure secure installation.

 

 

 

 

 

 

Fig 9.  After 2-3 rows. Adjust the distance to the front wall by placing spacers 3/8” on the side walls and the end wall. Once the adjustment is done against the main wall, continue to install till the last row.

 

 

 

 

 

 

Fig 10.  Last row (and perhaps also first row). The Minimum width of the last plank should be NOT LESS than 2” wide. Remember distance to wall is 3/8”.   Tip! Put a spacer before

measuring Cut the panels lengthwise and glue the short ends. See instructions below.

 

 

 

 

 

 

Special installations - Small panel widths

Joining at short ends length cut panels. Cut the tongue at the same time you cut the length of the panel and install as shown above. Please note that the smallest width of a panel is 2” at the last row. If it is not, the first-row width must be adjusted. This can easily be calculated when measuring the room with before installation. Cut off the locking element with a chisel, push the planks horizontally together. If necessary, place some spacers between the last panel and the wall to keep the planks together during the curing time of the glue.

Radiator pipes, Radiators, Toilets

Drill the holes ¾” larger than the diameter of the pipes. Cut out the panel (with the thinnest blade possible) as per diagram. Install the plank as per normal. Glue the cut-out piece back again.  For toilets, cut with a ¼” expansion around the flange. When you reinstall your toilet, the expansion will be covered.

Disassembly

Your floor can very easy be disassembled, which enables replacement during installation and during use. Separate the whole row by carefully lifting the whole row upward. Fold up and release the whole long side. Next, Disassemble the panels end joints by sliding horizontally flat on the floor and in opposite directions. (Do not fold up!)

Finishing the Job

• Protect all exposed edges of SUPERCore by installing wall base and/ or matching moldings. Use caution to prevent the fasteners from securing the planks to the subfloor. Do not allow the floor to become pinched. Considerations for transitions should be made for substrate changes, room to room environment changes, complicated layouts, and subfloor elevation. Caulk along tubs, toilet bowls, etc.

• After 48 hours, damp mop to remove residual surface dirt. Follow appropriate maintenance schedule using a quality rinse free cleaner.

REPAIRS

• SUPERCore is tough and durable, however, if a plank becomes damaged it can be replaced.

• If the damaged plank is along the perimeter of the room, the easiest technique is to just disconnect the planks until the damaged plank is removed. Replace the material and reassemble the planks.

• If it is impractical to just disconnect and reassemble the flooring, follow this procedure:

  • Using a circular saw and or a multi tool saw, cut out and remove the center of the damaged piece, leaving approximately a 1” (25.4mm) strip attached to the surrounding material.
  • Carefully cut back from the corners of the plank or tile to the inside edge.
  • Remove the edges by wiggling the cut plank out from the tongue and groove of the surrounding pieces.
  • Prepare the replacement plank by removing the leading edge of the tongue profile on the long side and the end of the plank. Careful not to damage the decorative surface. Also remove the bottom of the groove on the short end side by cutting on an angle to remove. Once the plank is prepared, install groove into tongue to test the fit. Once you check the fit is correct you are now ready to complete the install.
  • Position the replacement piece by engaging the groove into the tongue of the adjoining material. “Hinge” the prepared replacement plank into position.
  • Slightly lift prepared side of plank and apply a thin application of MSS 20 (Order Code: 832202) or MCS 42 (Order Code: 849832) onto the three exposed seams and carefully position plank into place, wipe excess from surface.
  • Use a hand roller to assist in aligning the edges into position.
  • Weight the replaced plank for at least 15 minutes until the sealer secures the material.

CAUTIONS AND MISCELLANEOUS

• Furniture should be moved onto the newly installed floor using an appliance hand truck over hardboard runways.

• Heavy furniture should be equipped with suitable non-staining, wide-bearing casters or protectors. Non-staining felt protectors are recommended for table and chair legs to help prevent scratching.

• Like with all floor coverings, it is best to protect SUPERCore installation from exposure to direct sunlight. A combination of heat and sunlight can cause most home furnishings to fade and discolor. Avoid exposure to direct sunlight for prolonged periods. During peak sunlight hours, the use of blinds or drapes is recommended.

• Oil or petroleum-based products can result in surface staining. Do not track asphalt-driveway sealer or automobile-oil drips onto the SUPERCore.

• Use area rugs or mats labeled “non-staining” that provide a manufacturer warranty against stains and fading.
