L.W Mountain SPC/WPC Installation Instructions
• Do not store directly on concrete, allow for air circulation. Do not open the cartons but spread them out and protect corners from damage.
• To minimize shade variation, mix and install planks from several cartons.
• Avoid exposure to direct sunlight for prolonged periods; such exposure may result in discoloration.
• All subfloor patching must be done with a Portland based compound and allowed to dry completely prior to installing flooring.
• This product can be installed on, above, or below grade.

Planks needed to complete your project: Measure the length and width of your room. If the room has alcoves or offsets, measure these separately. This will give you the square footage of the room. Purchase a minimum of 10% extra to cover mistakes, trimming, and for future needs and replacement. Most installations require about 10% overage. However, this can vary depending upon the room size, layout and the experience of the installer.
For best results it is important to purchase product (cases) from the same batch number (dye lot). Different batch numbers can have shade variations. Every case of flooring has the batch number printed on the end of the case. Batch number example: AS01. If you do have more than one batch number, we highly recommend you install planks from 4 or 5 different cases from different batch number at one time and randomly mix them into the installation as you go. This will insure a more natural looking floor.
CAUTION: Do not install SPC/WPC - Vinyl Planks over carpet. This product is not suitable for any outside use, solariums, sauna, or rooms that have the potential of flooding. We also highly recommend you do not install in rooms or homes that are not temperature controlled.
Acclimation: The home should be at “normal living conditions” for a minimum of 1 week prior to and during installation. L.W. Mountain, Inc. does not require that the SPC/WPC - Vinyl Planks be acclimated before installation. It is noted that in extreme temperatures (hot or cold), the product will be easier to work with if it is allowed to obtain a temperature of 60-70 degrees before installation. The home should be maintained at 55-85 degrees and 35-55% humidity.
• All subfloors must be clean, flat, dry and structurally sound. The correct preparation of the subfloor is a major part of a successful installation. Roughness or unevenness of the subfloor may telegraph through the new floor covering, resulting in an unsightly surface and may cause excessive wear on high spots. Subfloor must be flat- 1/8" in 10' or 1/8".
• Carpet staples or adhesive residue must be removed to insure proper installation.
• Any unevenness over 1/8” (3 mm) must be sanded down or filled with a floor leveler. Voids or humps in the subfloor will prevent the locking mechanism from locking properly.
1. Do not install SPC/WPC – Vinyl Planks over wood subfloors which lay directly on concrete or over sleeper constructions.
2. All wood and wood composition panels are suitable for the use under SPC/WPC – Vinyl Planks providing that they are smooth, flat, structurally sound and free of deflection. The panels include plywood, particle board, oriented strand board (OSB), flake board and wafer board.
3. Basements and crawl spaces must be dry. Use of a 6 mil. black polyethylene is required to cover 100% of the crawl space earth. Crawl space clearance from ground to underside of joist is to be no less than 18" and perimeter vent spacing should be equal to 1.5% of the total square footage of the crawl space area to provide cross ventilation. Where necessary, local regulations prevail.
1. The concrete subfloor must be dry, smooth and free from dust, solvent, paint, wax, grease, oil, and any other extraneous materials. The surface must be hard and dense, and free from powder or flaking.
2. New concrete slabs must be thoroughly dry (at least six weeks) and completely cured. The final responsibility for determining if the concrete is dry enough for installation of the flooring lies with the floor covering installer. Although SPC/WPC – Vinyl Planks are not susceptible to damage from moisture, excessive subfloor moisture is an ideal breeding ground for moldiness, mildew and fungus. The limited warranty does not cover discoloration from mold or from any kind of water damage caused by flooding, leaking or similar conditions.
3. Holes, grooves, expansion joints and other depressions must be filled with a latex underlayment, and troweled smooth and feathered even with the surrounding surface.
4. Concrete floors with in-floor radiant heating systems are allowed, provided the temperature of the floor never exceeds 85°F or 29°C. Before installing the flooring, the heating system must be turned on to eliminate residual moisture.
Existing Floor Covering:
1. SPC/WPC – Vinyl Plank can be installed over most existing hard–surface floor coverings, provided that the existing floor surface is smooth or can be made smooth.
2. Ceramic tiles should be made smooth by applying a cementitious overlay such as patching or levelling compound.
3. When the removal of the existing resilient floor covering is not an option then it must be covered with an embossing levelling compound or an equivalent to provide a smooth subfloor surface. Otherwise, telegraphing may occur.
4. Existing sheet vinyl should not be heavily cushioned and must consist of only one layer.
5. Never use solvents or citrus adhesive removers to remove old adhesive residue. Solvent residue left in and on the subfloor, may affect the new floor covering.
WARNING! DO NOT SAND, DRY SWEEP, DRY SCRAPE, DRILL, SAW, BEADBLAST OR MECHANICALLY CHIP OR PULVERIZE EXISTING RESILIENT FLOORING, BACKING, LINING FELT, ASPHALTIC "CUTBACK" ADHESIVES OR OTHER ADHESIVES.
These products may contain either asbestos fibers and/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 and may govern the removal and disposal of material. See current edition of the Resilient Floor Covering Institute (RFCI) publication Recommended Work Practices for Removal of Resilient Floor Coverings for detailed information and instructions on removing all resilient covering structures.

NOTE: Before laying out the floor, check the wall you are starting from and make sure it is square to the opposite wall. Simply measure the room from opposite ends of the wall to the far wall. If the measurements are different, you can make adjustments on the first row by scribing the plank. SPC/WPC – Vinyl Plank is designed to be installed with the floating method. Never secure the planks to the subfloor. Always undercut all doorjambs. Never fasten wall moldings and or transition strips to the planks.
1. Starting from the corner, lay a row of loose planks without securing them to each other first to determine if you need to adjust the layout or scribe the first row to conform to the starting wall.
2. Installation should start with the first piece in a corner and proceed from the wall with the groove facing out away from the wall. Allow a minimum gap of 1/4” for subfloor movement or product expansion, which should be covered by molding.
3. Line up the end of the next piece by overlapping the first. Using a rubber mallet, tap the joint together with a downward motion until the tongue and groove are securely locked. Continue in this manner until you have reached the end of the first row.
4. Be sure to keep the seams tight. You will feel and hear the click when locking the planks together to create a tight seam. There should be no gap visible between planks. If your seam appears not to be tight, you can immediately pull apart the planks and reapply it. Slowly and carefully lift the top plank away from the bottom plank and simply apply them repeating Step #3. Be careful not to pull the planks apart too fast or you could rip or damage the Locking Strip.
5. When installing SPC/WPC - Vinyl Plank, it is strongly recommended to stagger the rows so that the short edge (7”) seams are not in a straight uniform line. We recommend staggering the end-joints by a minimum of 8” but maintaining a random layout. Do not create a pattern.
6. Interlock the first plank tightly against the first row (long side) at a 15-20-degree angle.
7. Align the end of the next plank over the end groove of the previous plank and lower the side joint together. Tap the end joint down with the rubber mallet using a downward angle towards the adjoining plank until the tongue and groove lock together.
8. Inspect each plank after install to assure the long and short ends are tight.
9. Continue with the installation in this manner. Use end cuts as starters for the next rows as long as proper stagger is maintained.
NOTE: When cutting SPC/WPC - Vinyl Plank for length, be sure to always cut the short side of the plank with the groove edge. The remaining piece can then be used on the opposite side of the room at the end of that row if layout permits.
10. To fit around irregular objects, simply make a pattern out of heavy paper. Place the pattern upon the plank and trace. Cut along trace lines using a jigsaw. Be sure to leave a minimum of 1/4” expansion space around all fixed objects, floor vents, and door frames and walls.
11. When installing under door jambs, it may be required to carefully shave the top ledge of the groove. Use wood glue applied to bottom lip of the groove to secure. Hold in place with painter’s tape until glue is dry.
12. After complete, reinstall or add new quarter round to cover expansion space. Only nail straight into the wall base, do not nail down through the floor into the subfloor as this will eliminate the expansion properties.
13. Add appropriate transition moldings. Make sure the floor can float under the overlap of each transition profile.
• This is a floating floor system. As with all floating floors, do not install cabinets on top of flooring. The cabinets must be installed first and the flooring cut around them.
• Do not install in rooms or homes that are not temperature controlled. Exposure to long term direct sunlight can cause damage to your floor.
• Furniture should have felt pads attached to all legs and all metal tabs/nails removed.
• Do not use ball type castors as they can damage the floor. All castors or wheels should be easy swiveling and suitable for resilient flooring.
• SPC/WPC - Vinyl Plank is approved for installation over In-floor Radiant Heat. Floor temperature must not exceed 85 degrees Fahrenheit.
