NatureTEK Plus™ is a durable oor covering, not intended as structural material. NatureTEK Plus requires a clean, dry, secure
suboor that meets building codes. The following requirements are not intended to supersede federal, state or local building
codes, but as with many other interior nish products, may require modifying existing structural components for successful
installation. Owner assumes responsibility for compliance with all building codes. NatureTEK Plus ooring is suitable for use
in climate controlled (35-65% RH and 60-85° F) indoor installations only and should not be installed in rooms with oor drains
or sump pumps. NatureTEK Plus oor can be installed above, on or below grade. A moisture test is strongly recommended to
determine if high moisture exists in the suboor. When using a calcium chloride moisture test for concrete suboors (ASTM
F1869), values must be ≤ 5 lbs/1000ft²/24-hr or <80% RH with an in situ probe (ASTM F2170). Moisture readings of wood
suboors must be ≤ 12%. Acceptable job site conditions, including relative humidity and suboor moisture conditions, must be
maintained throughout the lifetime of the ooring. NatureTEK Plus ooring is installed as a oating oor and requires the use of
T-moldings in doorways less than 32-inches (0.81m) or if the installation changes directions through the doorway (regardless
of doorway size) and in rooms 50 feet (15.24m) or larger in length or width. Floor movement must not be constrained by
glue, nails, screws, hardware or other xed obstructions. This product must be installed in accordance with these installation
instructions.

INSTALLATION INSTRUCTIONS
SITE AND MATERIAL PREPARATION
A. Remove carpet and padding. Also remove any wood ooring installed on concrete. Do not remove products unless they are
asbestos-free.
B. Undercut door frame and wallbase. Slide the ooring at least 1/4” underneath the door frame and wallbase. Also leave a
concealed 3/8” minimum expansion space under each.
C. Remove bumps or peaks in suboor and ll depressions with oor leveling compound to ensure no more than 3/16”
unevenness per 10 foot span.
D. Acclimate unopened product before installation. If there is no time for acclimation, there should be no more than a
difference of 25° F and 20% relative humidity between the stocking/transportation environment of the flooring and
the final installation environment of the flooring.
E. Clean debris from suboor before installation.
F. For concrete suboors, install vapor barrier with overlapped seams of 8” or more.
G. For planks without attached underlayment, install over single layer of underlayment appropriate for NatureTEK Plus
oors.

FLOORING INSTALLATION
1. Inspect each plank. Floor should be installed blending planks from several cartons at the same time to ensure good color
and shade mixture throughout the installation.
2. For the rst row along straight walls, remove the tongue on all long side joints and on the short side of the rst plank only.
3. For uneven walls, trace contour on tongue side of plank and cut.
4. Assemble the rst row tongue side toward wall. Insert the end tongue into the end groove and rotate downward to
assemble. Keep the planks aligned and the joints closed.
5. Two spacers thick side to thick side equals 3/8”.
6. Provide a 3/8” space for expansion on all sides. First piece must be at least 8” long. Start new rows with pieces trimmed
from previous row. Ensure at least a 6” end joint offset.
7. At a slight angle, insert the tongue of plank 2 into the groove of plank 1 until the NatureTEK Plus edges meet, and then
rotate down until the joints lock.
8. Join the short end of the plank rst. There will be a gap on the long side joints when the plank is rotated down.
9. Raise the outside edge of the plank upward approximately 1”. Maintain this angle as you push the plank in until the
NatureTEK Plus edges meet.
Rotate downward on the plank until the joint locks. Repeat these steps to complete the installation.
Installation Tip: Place a carton of planks across the end of the row being installed to keep installed planks in place
during installation.
10. Alternate Tap Method: Align the tongues into the grooves of the long and short sides of the planks. Install the long side
rst with a tapping block by tapping lightly along the long side until the joint is closed tightly. Then tap the end using the
tapping block into a locked position. Note: Uneven tapping or use of excessive force may damage the joint.
11. Ensure there will be a 3/8” gap (after the joint is closed) to the wall for expansion.
12. For the last row, align the plank to be used on top of the second to last row. Using a full width plank as a spacer, trace wall
contour and cut plank.
13. For the last row, install the long side tongue into the groove with the end joint aligned. Using a pull bar and hammer, work
evenly along the length of the plank and lightly tap the joint closed.
14. After tapping the long side joint closed, tap the short side closed, using a tapping block or a pull bar.
Installation Under Doorway Frames
15. Slide plank under pre-cut door frame.
16. Tap the long side joint closed rst. Then tap the end joint closed.
Installation Around Fixed Objects (Such as Pipes)
17. Allow 3/8” expansion space around pipes or other xed objects.
Finishing the Installation
18. Remove all spacers.
19. Create a watertight seal by applying exible 100% silicone sealant to the entire perimeter of the installation. DO NOT use
acrylic sealant.
• First ll all expansion spaces with 3/8” compressible PE foam backer rod and cover with silicone sealant.
• Prior to installing the moldings, apply silicone sealant to the portion of the molding or transition that will contact directly
with the NatureTEK Plus ooring surface.
• Install moldings and immediately wipe away any excess silicone sealant.
• Apply silicone sealant at connections to doorframes or any other xed objects.
CARE AND CLEANING
Place felt oor protectors under legs of moveable furniture. Chair casters should be rubber – not plastic or metal. Place walk-off
mats at entrances. Dust mop as primary cleaning method. Occasionally wet mop with water only, using a well wrung out mop;
DO NOT pour liquid directly on oor or use an excessively wet mop that will puddle or leave moisture standing on the oor. If
needed, use a solution of 1 cup of vinegar per gallon of water OR 1/3 cup non-sudsing ammonia per gallon of water. DO NOT
use detergents, abrasive cleaners, soaps, waxes or polishes. Use correct hard surface vacuum tools. DO NOT use rotating
beater bars, oor scrubbers, steamers, jet mops, buffers or similar products. Wipe up spills immediately. DO NOT allow topical
moisture to remain on the floor longer than the time specified in the product warranty.
IMPORTANT HEALTH NOTICE FOR MINNESOTA RESIDENTS ONLY:
THESE BUILDING MATERIALS EMIT FORMALDEHYDE. EYE, NOSE, AND THROAT IRRITATION, HEADACHE, NAUSEA AND
A VARIETY OF ASTHMA-LIKE SYMPTOMS, INCLUDING SHORTNESS OF BREATH, HAVE BEEN REPORTED AS A RESULT OF
FORMALDEHYDE EXPOSURE. ELDERLY PERSONS AND YOUNG CHILDREN, AS WELL AS ANYONE WITH A HISTORY OF
ASTHMA, ALLERGIES OR LUNG PROBLEMS, MAY BE AT GREATER RISK. RESEARCH IS CONTINUING ON THE POSSIBLE
LONG-TERM EFFECTS OF EXPOSURE TO FORMALDEHYDE. REDUCED VENTILATION MAY ALLOW FORMALDEHYDE
AND OTHER CONTAMINANTS TO ACCUMULATE IN THE INDOOR AIR. HIGH INDOOR TEMPERATURES AND HUMIDITY
RAISE FORMALDEHYDE LEVELS. WHEN A HOME IS TO BE LOCATED IN AREAS SUBJECT TO EXTREME SUMMER
TEMPERATURES, AN AIR-CONDITIONING SYSTEM CAN BE USED TO CONTROL INDOOR TEMPERATURE LEVELS.
OTHER MEANS OF CONTROLLED MECHANICAL VENTILATION CAN BE USED TO REDUCE LEVELS OF FORMALDEHYDE
AND OTHER INDOOR AIR CONTAMINANTS. IF YOU HAVE ANY QUESTIONS REGARDING THE HEALTH EFFECTS OF
FORMALDEHYDE, CONSULT YOUR DOCTOR OR CALL THE LOCAL HEALTH DEPARTMENT.
