General Instructions iCORE Laminate Advanced Composite Flooring is designed to be installed using the "floating" floor system. This means that the planks are not secured to the subfloor but, rather, the planks are secured to each other by means of a co-extruded spline. This patent-pending system is the Mannington exclusive SNAP&FITTM installation system. The iCORE planks are constructed using Mannington's patent-pending iNNERCORETM Technology, an extruded synthetic core. Each iCORE plank is 5" wide by 72" long designed with a micro-bevel edge that provides for greater depth and dimension. Combined with the realistic embossing, iCORE planks have a natural wood grain appearance and texture. Another unique feature of iCORE is the double groove construction, which provides a groove on each side of the plank. This allows the planks to be turned 180° to each other to add an even more realistic visual to the overall layout. Storage & Handling Always store iCORE horizontally on a fully supported flat surface. Do not stack pallets more than two high. Protect packages from forklift or other traffic. iCORE should be stored in a temperature-controlled interior location. NOTE: Use care when handling cartons to protect corners. Transport horizontally on a fully supported flat surface. Jobsite Conditions iCORE does not need to be acclimated to jobsite conditions. However, avoid extreme temperature changes from storage and transporting to jobsite conditions. Optimum jobsite temperatures should be between 60°F and 95°F. iCORE may be installed over radiant-heated floors. The heating unit must have a regulation system to limit surface temperature of the floor's surface to a maximum of 90°F Subfloor/Underfloor Recommendations & Requirements iCORE can be installed over all structurally sound wood or concrete subfloor systems on all grade levels. Subfloors must be clean and free of debris. The subfloor must also be smooth and flat to within 1/4" per ten-foot span. All low spots must be filled with a high quality cementitious compound, like Mannington MVP 25, and sanding or grinding must remove all high spots. iCORE can be installed over most existing hard surface floor coverings. Heavily textured ceramic tile must be smoothed and leveled with MVP 25. iCORE should never be installed over cushioned carpet. The patent-pending iNNERCORE Technology of iCORE is waterproof and can be installed on all grade levels of concrete subfloors without the need for a polyethylene moisture barrier or underlayment. However, it should be noted that although iCORE is not affected by subfloor moisture vapor transmission, excessive subfloor moisture is an ideal breeding ground for mold, mildew, and fungus. These bacteria can contribute to an unhealthy indoor environment. For this reason we suggest that iCORE should not be installed over concrete subfloors that have a history of moisture problems. Wall Base Removal & Installation Preparation Carefully remove all existing wall base, trim, and transition moldings using a pry bar. Measure out the entire work area to ensure proper panel layout. Keep in mind the last panel to be laid in the work area must be at least 2" wide. A calculator may be helpful when figuring out how to arrange the floor. A Mannington iCORE panel measures 5 " wide. Divide the work area in inches by the panel width (5"). This number will tell you how many panels are required across the room. It will also help you figure out the width of the last panel. If the last panel will be less than 2" wide, the first panel to be laid must be cut to compensate for the difference on the last panel. For example, if your room measures 148" wide, then your last panel would be 1" wide, less than the 2" panel width minimum. You must cut the first panel to measure 3" to compensate for the last panel, which would then also measure 3". NOTE: No additional underlayment is required with iCORE, however some additional sound dampening can be provided by using the Mannington® Hush Underlayment. Mannington Hush Underlayment is available in 300 square foot rolls. If you elect to use the Hush Underpayment be certain to take into account the addition al thickness when undercutting door casings. Use a scrap piece of the new iCORE flooring as a guide. Be certain to allow enough room under the casing for a 5/16" expansion gap. Lay the panel face down over a sheet of Mannington Hush and against the frame to act as a cutting guide. Make the cut using a hand or power jamb saw and simply slide the panel underneath the door casing. Laying & Adhering iCORE Laminate Advanced Composite Flooring is designed to be installed using the "floating" floor system. This means that the planks are not secured to the subfloor but, rather, the planks are secured to each other by means of a co-extruded spline. This patent-pending system is the Mannington exclusive SNAP&FITTM installation system. One of the most important aspects of Mannington iCORE Laminate Floors installation is the precise placement of the first three rows of laminate panels. If the first three rows are square and tight, the rest of the installation process will go much smoother. Pay particular attention to the directions outlined in the following pages so you will be able to assemble your first panels correctly and hassle-free. NOTE:Mannington iCORE Laminate Floors are intended to be installed as a floating floor system. Never secure flooring to the underfloor with nails, glue, or screws. Once the starting wall has been determined, begin laying the iCORE planks along the wall using spacers or adjust able wedges to maintain the expansion gap. It is imperative that this row be installed straight and tight at all end joints. Cut the last plank to fit. NOTE: iCORE planks can be cut using traditional cutting tools such as hand saws, jig saws, circular saws, power miter or chop saws, etc. Establish an area away from the work area for cutting and utilize "dust" containment systems when cutting. Keep the debris created when cutting out of the work area. iCORE splines are specifically designed co-extruded splines that are used to secure the planks together. The splines are 84" long and are packaged 21 splines per carton. One carton is required for every 60 square feet (3 cartons) of iCORE Laminate. iCORE co-extruded splines can be cut with side cutters, vinyl molding cutters, or with a utility knife. The splines should be staggered so they bridge the planks by extending at least 12" into the length of the adjoining plank. Insert the iCORE splines into the groove along the first row. It is recommended to keep the stagger of the spline ends as far as possible from the plank ends. For example, if a full plank is used as the first plank in the layout, cut a spline to a length of approximately 30". Insert this spline in the first plank, install the second plank, and insert a full 84" long spline. This will provide 42" of spline in both panel grooves. NOTE: Maintain as much stagger with the splines as possible to help "lock-in" the planks. Never allow an end joint of a spline to fall in line with an end joint of an iCORE plank. Typically the cut-off plank from the first row can be used to start the second row providing that it is 12" or longer. Stagger the end joints of the second row by at least 12" from the end joints in the first row. Position the groove of the planks onto the splines with slight hand force. Insert the splines into the grooves of the second row and using a tapping block and hammer firmly secure the second row to the first. Be careful not to exert too much force with the tapping block on the edge of the co extruded spline. To prevent damaging the laminate plank edge, always tap on the splines and never tap on the plank edge. Install the third row of iCORE planks using the same procedure. Randomly stagger the end joints to achieve a random and an aesthetically pleasing appearance. Closely inspect these first three rows to assure that everything is straight and true. Be certain that all end joints are tight and aligned. If necessary, adjust these three rows of iCORE planks using adjustable wedges or spacing wedges before proceeding with the installation. It is some times helpful to secure the alignment of these three rows with blue, non-marring masking tape. Continue installing the planks across the work area. Remember that the double grooved construction of the iCORE planks allows the panels to be turned 1800 to each other to provide for a realistic random appearance. Periodically throughout the installation check to be certain that the panels are staying straight and true. Maintain the 5/16" expansion gap. More than likely the last row of planks will need to be rip cut to fit. Remember this last row must be at least 2" wide. Scribe the last row of panels as required maintaining the 5A6" expansion gap. Install the cut planks and pull into place with a pull bar. Using iCoreWeIdTM After the installation is completed all end joints must be welded with CoreWeld. CoreWeld is a solvent-based compound that is used to seal the end joints of the planks so that no topical water can seep through to damage the subfloor. CoreWeld is available in 8-ounce containers. Eight ounces of CoreWeld will weld approximately 200 square feet of iCORE planks. Fill the CoreWeld applicator and screw on the applicator tip. Snip off the very top of the applicator tip. Apply an even application of weld to all end joints. To increase the impermeability of the entire iCORE installation the weld may be applied to all side joints as well. The majority of the CoreWeld will penetrate into the joint and will also evaporate quickly from the surface of the flooring, however, wipe the area with a clean cloth to ensure that all of the CoreWeld has been removed from the surface. NOTE: After welding is complete, pour unused weld back into the can. Do not store CoreWeld in the applicator bottle. All wall base and/or quarter round should be installed to hide the expansion gap. Be certain to nail into the wall and not into the flooring. Mannington offers matching reducers, end cap, step nosing, T-molding, and quarter round for all ICORE plank patterns. Use the appropriate transition moldings at all door thresholds, steps, or other floor coverings.
