• Patterned styles. Stage each roll by pattern length instead of roll number as outlined below.
• Implement roll sequence when possible after pattern length.
PATTERN STYLES WITH INTEGRA HP BACKING
• Patterned styles must be staged by pattern length rather than roll number sequencing. Patterns often vary especially in
longer drops. Measure pattern lengths on each roll and sequence rolls as detailed here.
• Pattern sequence. Rolls with longest patterns must be installed first followed by rolls with gradually decreasing pattern
length. Rolls with shorter patterns must be power stretched into alignment with longer patterns. Even when pattern
sequence is provided, always double check on site and sequence rolls as follows:
1. Count full patterns. Count only full patterns within an approximate 10 foot length on each roll. Five foot lengths can be
used for very smaller patterns. Multiple patterns must be measured in a group to get the most accurate sequence
possible. The multiples used here can make this important process more simple, consistent and accurate.
2. Measure lengths. Carefully measure length on a group of patterns, starting at the upper tip of first pattern to lower tip
of the last pattern. Pattern grouping will likely be slightly longer or shorter than exactly 120 inches (10 feet). Fractions
of an inch matter.
3. Check and record pattern sizes in at least two locations on each roll.
4. Create sequence list. Note roll number, pattern count, and length measurement.
5. Longest patterns first. Stage each roll so the roll/rolls with longest patterns are installed first. Install each roll so pattern
groups get progressively shorter.
Pattern length always varies within a run. Six patterns on Roll 1 total
119¾-inches tip-to-tip, while six full star patterns total 120-inches on Roll 3.
On Roll 2, six patterns are 120
1/3
-inches long. These rolls must be sequenced,
alligned, and installed by pattern length as follows:
v
Roll 2
has the longest six patterns and must be installed
first
.
v
Roll 3
has slightly smaller patterns and should be instslled
second
.
v
Roll 1
has the shortest grouping of six patterns and must be installd
last
.
Power-stretch shorter patterns into allignment with longer patterns. Maintain
stretch, stay nail to hold patterns in allignment and leave nails in place until
adhesive has firmly set.
MAKING CUTS:
Integra HP broadloom requires a specific tool and technique for creating
seams that are consistently tight and secure. Follow these specific instructions when cutting
seams.
• Seam cutter. Only use the 575 Commercial Seam Cutter by National Carpet Equipment
(800-245-0267) to prevent fullness. Fullness will cause seam to peak before the wet set
adhesive can develop grab.
• Side seams. The 575 cutter is designed to row cut top width while simultaneously trace
cutting a second width positioned underneath. This double cutting method combines row
cutting and trace cutting for a net cut without fullness.
• Dry cut all seams. Avoid making double or trace cuts after adhesive has been spread. Making cuts in wet adhesive (wet
cutting) removes adhesive underneath seam; wet glue transfers to the portion of carpet backing being trimmed away. This
installation technique will cause seam failure and should never be used. Spread adhesive along the seam area only after
cut is made and while subfloor is still adhesive free or dry.
• Side seam cuts. Making side cuts requires significantly different techniques depending on whether the carpet style
involves a random or distinct pattern.
1. Random or non-patterned styles should be double cut along a straight line.
2. Patterned styles should be cut on each width separately by following a straight edge from pattern to pattern.
ADHESIVE:
Integra 2 is a wet-set adhesive required and specifically tailored for both Integra HP and Integra HP RE
backings. The wet-set properties of Integra 2 differ from other types of adhesives that need some drying or open time
before installing flooring material. Integra 2 permits immediate installation of Integra HP and provides essential wet
adhesive transfer from subfloor to Integra HP vinyl backings. Both Integra backings require this transfer of wet adhesive
before a secure bond can develop. Integra 2 adhesive is for use with HP backings only and no other flooring.
Note these
important precautions prior to installation.
• Wet only: Once spread onto the subfloor Integra 2 should never be allowed to skim over or begin drying from the surface
before installing carpet with HP backing.
• Cure times: HP backings are designed to prevent moisture penetration. That means wet adhesive may need several days
