Installation Instructions

2. PATTERN BOW: (WIDTH AND LENGTH)
a. For width bow, pick two identical pattern points on the same widthwise pattern line - one at the left edge and one at the right.
b.Pull a chalk line or tightly stretched string between these points across the width (12’ or 13’6”-3.66m or 4.1m). Measure the distance between the chalk line or string
and
the same pattern point at the point of greatest separation. This will be more than 1”(2.5cm) across 12’ or 13’6” (3.66m or 4.1m).
c For length bow (also called “trueness of edge”) use the same procedure connecting common pattern points 40 feet (12.6m) apart along the edge of the carpet. The pattern will
be no more than ½” (12.8mm) from the string or chalk line.
3. PATTERN BIAS:
a. Starting at the same pattern points isolated in the width bow measurement – call these “A” and “B”, measure lengthwise along both selvage edges exactly 9’ and mark these
points with a small piece of tape. Call these points “C” and “D”.
b. Measure from point A diagonally to Point C and from Point B diagonally across to Point D. The difference between these measurements will not exceed 2-3/8” (6.0cm). More
detailed information sheets on each of these criteria are available if needed.
4. GENERAL PATTERN PROCEDURES – STRETCH-IN INSTALLATIONS:
• Group rolls and cuts working from the longest pattern repeat gradually down to the shortest.
• Shift trimmed breadths to achieve a match near the mid point of the seam.
• Insert hot melt tape under seam.
• Melt together that portion of the seam that is visually acceptable.
• Using a power stretcher or knee kicker, stretch along the “short” side (smaller pattern repeat) in 3 to 5 foot (1 to 1.6m) sections.
• As each small section of the seam is matched, insert seaming iron and prepare that section. Leave stretcher locked in position until each section cools.
• Do not complete any section of seam that does not match.
• Once all seams are matched and complete, the entire installed area is stretched as described in the above diagram.
• Width Pattern Bow up to ½” (1/2cm) and all pattern bias is dealt with during the power stretching process.
• Width Pattern Bow between ½” and 1” (1.2 cm / 2.5 cm) must be dealt with as the seams are assembled, working both sides of the seam simultaneously with knee
kicker, power stretcher, OR “crab” stretcher as required.
• Patterned Corridor Carpets (runners and caps) are subject to the same variations and are cut, pattern matched and installed using the techniques above. Maximum
pattern width variation is ½” in 6’ (1.3 cm in 1.8 m). For best results keep right side runners with right side caps and left side runners with left side caps.
• These same procedures also apply on all end or “cross” seams. These seams are usually assembled from one side to the other across the width of the material.
DIRECT GLUE-DOWN INSTALLATION:
RECOMMENDED ADHESIVES:
Milliken Broadloom Carpet Adhesive - Product i.d. # 500579/735/00001 in 5 gallon (18.9liter) pails and #500583/774/00001 in 4 gallon (15.2Liter) pails is the
ONLY recommended adhesive for all Milliken broadloom products and should be ordered with the carpet. This applies to all products having the ActionBac® secondary and to
all attached cushion products. This adhesive product carriers the CRI “Green Label” and is specifically designed to provide optimum performance with all Milliken broadloom
products regardless of the installation method chosen.
COVERAGE:
• Direct glue- ActionBac® and attached cushion - 10 to 15 sq. yds. per gallon using a 1/8” x l/8” x 1/16” (3.2 mm x 3.2 mm x 1.6mm) “V” notched trowel
• Double Stick – Between Cushion and Carpet -6 to 8 sq. yds. per gallon using a 1/8” x 3/16” x 1/8” (3.2mm x 4.8mm x 3.2mm) “U” notched trowel or as recommended
by the manufacturer of the double stick system being used.
FLOOR PREPARATION:
• All dust, foreign matter, non-compatible adhesive residues, grease, paint, wax, oil, dirt, etc. should be removed.
• Cracks, holes and depressions should be filled with a Portland cement based patching material. Protrusions should be removed.
• Floor surface should be smooth and non-undulating to within 1/8” (3.2 mm) in 10 feet (3.0 meter) in conformance with ACI standards.
• Standard Alkalinity and moisture tests should be performed. Concrete slab pH should not exceed 9.0. Excessive moisture will interfere with the curing/performance
of the adhesive. Water vapor transmission should be exceed 3#/1000 sq. feet (1.4 Kg/93M
2
) /24 hour period as determined by the anhydrous calcium chloride test
performed in accordance with ASTM F-1869-98. Milliken subscribes to the industry position that this testing should be performed by an independent agency trained
and certified to perform this testing.
• “Sealing” of concrete floors is at the discretion of the flooring contractor. In general, properly cured and dried (90 days minimum) steel trowel finished concrete
requires no additional treatment. Excessively porous or dusty concrete slabs are the only exceptions. Please call Technical Services if you have questions. KURE-
N-SEAL WB from Sonneborn (800-243-6739) is a recommended product should this type of treatment be deemed necessary. This type of “sealing” is not a curative
for excessive water vapor emission. If out of tolerance emission levels are encountered, call Technical Services for assistance.
INSTALLATION PROCEDURES – ADHESIVE INSTALLATION;
• Trowel notch size, shape and adhesive coverage rate MUST be maintained as noted above. Insufficient adhesive is the #1 cause of failure in all adhesive
installations.
• Proper open time must be allowed – temperature and relative humidity influence adhesive open time.
• If patterned carpet is being installed, installation sequence MUST be determined based on pattern repeat size as described above. There is no requirement for roll
number sequence to be followed. L.P.R. Bow and Bias amounts are printed on the packing list and roll tag for added convenience.
• On non-patterned loop pile carpets, row-cut one of the breadths to be seamed, overlap this edge over the second breadth, and scribe cut to the row-cut edge. This
method does not
apply on patterned carpets. These must be cut along complementary pattern characteristics to insure a proper match. The use of hot melt
seaming tape to achieve and secure pattern match is strongly recommended on all “double stick” installations and is very helpful on direct cement installation where
repeat variation is significant. Orcon K-80 seam tape is the recommended product for both direct and “double stick” applications.
• Obtain a net seam – do not compress – use knee kicker or “crab” stretcher to position.
• Bead all edges with seam sealer on all carpets regardless of construction. (See previous section on seaming procedures and recommended products)
• Avoid air entrapment – lay carpet into adhesive working in both directions from center. Depending on the amount and type of pattern variation present, it is
sometimes necessary to vary the way the carpet is placed back into the adhesive. For severe bow or bias it is more efficient to roll the carpet into the adhesive end
to end in short sections working and straightening each section before proceeding. Where significant pattern repeat variation is present it is generally easiest to
assemble the seams “dry” using the K-80 seaming tape noted earlier and then roll the carpet “sideways” to expose the floor under the seam. The backing paper on
the K-80 is then removed and adhesive spread. The carpet is rolled back into the adhesive once the proper open time is observed.
• Roll with 75 lb. (34Kg) roller in both length and width directions or as directed by the cushion manufacturer in “double stick” applications.
• Restrict heavy traffic and furniture movement for 24 hours.
Milliken cannot be responsible for pattern match in Direct Glue-Down Installations. This includes all “double stick” methods.
If a consumer desires as adhesive installation, carpet must be inspected for visible manufacturing defects prior to installing. Once installed,
Milliken will decline all complaints except for latent defects. Sequencing of rolls by pattern repeat is mandatory for success when installing
patterned carpet in any direct glue or “double stick” application.
