3. Thoroughly sand the surface with coarse sandpaper using a edge
sander next to the walls and in spots where a regular sander may
have skipped. Completely remove all the old sealers and waxes to
ensure a proper bond.
4. Thoroughly sweep, vacuum, and then damp mop the floor to remove
any remaining dust and grit.
WARNING:
Various government agencies have regulation governing the handling,
removal and disposal of asbestos containing materials. If you intend to
sand, remove, or dispose of an existing resilient floor covering, backing,
lining felt, or adhesive you should be aware that these products may
contain asbestos fibers. Sanding, removal and the disposal of asbestos
containing material can place fine particles of asbestos in the air. Is has
been determined that the inhalation of free airborne asbestos fibers maybe
injurious to your health. Fines may be assessed against persons violating
these regulations.
NOTE: VPI Resilient Floor Coverings and adhesives have never
contained asbestos.
METAL DECKS:
Metal decking must be smooth, dry, clean and free from dust, paint,
asphalt, old adhesives, grease, oil, rust and other extraneous material.
Level all surface irregularities with a Portland Cementitious liquid latex
underlayment. Lightly sand the surface for better adhesion.
WORK BENCHES:
Tile can be applied to either wood or metal work bench surfaces. The
bench surface must be smooth, dry, clean and free from paint, oil grease
and other extraneous material. Metal surfaces should be lightly sanded for
better adhesion.
Install tile in general accordance with the instructions under Adhesive
Installation.
OTHER TYPES OF INSTALLATION:
For recommended procedures on other types of installations not covered in
these instructions, contact the manufacturer before installation commences.
LOT NUMBERS:
Each production run of tile is assigned a lot number which appears on the
carton label. Check lot numbers before installing the tile. Whenever
possible, install the tile from the same lot number in a given room or area.
When this is not possible, it is advisable to isolate the different lot numbers
into separate areas. Because few rooms are perfect rectangles and the tile
must be laid within a perfect rectangle, it is necessary to strike chalk lines at
right angles to each other against which the tile can be laid.
GROUNDING SET UP REQUIREMENTS:
Several acceptable methods are used to ground ESD Control Floors,
depending on job conditions and/or personal preference. Two
recommended procedures are described:
OPTION 1
Prior to installation of the static control flooring, the electrical contractor
drops a wire (usually a #10 or #12 stranded) inside the wall from any
convenient ground bus so that the wire emerges at the floor wall
junction. A small hole is either cut into the drywall at this point or
chipped out of the concrete floor.
The copper (2” x 24”) grounding strip provided by VPI is intertwined with
the stranded copper wire. The connection of grounding strip and
copper wire is pushed into the depression and conductive adhesive is
liberally applied so that the connection is completely buried. Then the
adhesive and the depression is filled to the level of the floor or wall.
The balance of the grounding strip is then laid flat in conductive
adhesive on the floor and covered with additional adhesive. The tile is
then installed over the grounding strip.
OPTION 2
If there are exposed steel columns supporting the building, the ground
connection may be made directly to the columns.
The copper grounding strip is laid flat in the conductive adhesive on the
floor allowing several inches to protrude at the junction next to the
column. The grounding strip on the floor is covered with additional
adhesive and Conductile or Statmate tile installed over it. A hole is
drilled into the steel column an inch or two up from the floor. Tap the
hole and secure the grounding strip using a simple machine screw and
washer. Make sure all paint and foreign substances have been
removed from the column to assure good metal contact. Cover the
connection with an electrical box.
VPI provides sufficient copper strip to allow one ground connection
every 2,000 square feet of installed tile. Copper strip grids under the
tile are unnecessary since the conductive adhesive acts as a
conductive plate beneath the tile.
ADHESIVE APPLICATION TYPE:
VPI 150 or VPI 165 is an integral component of the EDS control
system. Use of non-VPI Conductive Adhesives will void VPI’s Limited
Warranty.
VPI 150 ADHESIVE:
150 Adhesive has superior bond strength on, or above or below grade
applications where moisture may be a concern.
CHARACTERISTICS: 150 Epoxy adhesive is different from other
adhesives; they do not develop tackiness as it sets up. This makes it
extremely important to roll the floor as recommended to avoid raised edges
or adhesion problems.
CLEAN UP: Remove uncured adhesive by blotting with alcohol or mineral
spirits. Do not smear adhesive. Use Original Soft Scrub™ (Paste) to
remove remaining stains of wet or cured adhesive. During initial
maintenance, dry buff these areas with a red pad on a low speed buffer to
restore the factory finish.
SET-UP TIME: About 30 minutes, do not spread more than you can install
in that time. Appearance is glossy when first spread and dulls as it sets up.
Maximum open time: 30 minutes. Exceeding the 30 minutes open time will
lead to floor failures due to poor adhesion.
TROWEL TYPE: 1/16” x 1/16” Square Notched Trowel
Never re-notch a trowel, the tines wear down reducing the amount of
adhesive needed for a good adhesion to the product.
SURFACE TYPE: The Adhesive is good for Porous and Non-Porous
areas.
COVERAGE: 90 - 135 sq. ft. per gal. depending on porosity of
substrate, application style and environment. In applications
demonstrating spread rates that are less than 90 SF, additional
adhesive should be purchased as required. MVER<5LBS, RH
≤85%, pH of 6 - 9
VPI 150 TWO PART EPOXY ADHESIVE INSTALLATION
INFORMATION:
1A. Prior to the installation, remove the cartons from the pallets, and place
them on a flat floor surface at 70 degrees or at the expected
temperature of operation for a minimum of 48 hours.
1B. After acclimating, and prior to installation, wipe the back of the tile to
remove any manufacturing residue or contaminants.
1C. “IMPORTANT” Before starting the installation and in order to reduce
tile ledging and gapping, the general conditions (ambient temperature,
slab temperature) at the time of installation should match the planned
operational general conditions.
2. All sub-floors must be clean and dry, free of dust, dirt, wax, paint,
grease, manufacturing residue or any other contaminates that might
interfere with the adhesive bond.
3. Cracks and uneven surfaces must be filled with an approved
cementitious based patching compound.
4. Using mixing paddles provided or mixing paddles on an electric drill to
carefully stir Part A and Part B separately until homogenous. Pour
Part B into Part A. Be sure to remove as much of Part B from the can
as possible by scraping the sides and the bottom of the container with
appropriate paddle provided. Mix in container provided only.
5. ESD floors must be grounded every 2,000 sq ft or each area if less
than 2,000 sq ft. SEE GROUNDING SET UP REQUIREMENTS.
6. The adhesive should not be poured onto the floor until Parts A & B
have been properly mixed together. Any unmixed portion applied to
the sub-floor will not adhere and cause an adhesion floor failure.
7. Mix the combined Parts A & B using a slow speed drill (200 RPM’s)
and mixing paddle. Mix for a minimum of 4 minutes and less than 10
minutes. Do not mix at high speeds. This could cause the adhesive
to start the curing process and shorten the open time. Extended
mixing longer than 10 minutes may adversely affect the adhesive. Be
sure to mix the entire contents of the can.
8. If mixing by hand, use a rotary motion while at the same time lifting
from the bottom. Periodically scrape the sides and the bottom of the
adhesive can to insure complete mixing of both parts. Mix a minimum
of 5 minutes.
CAUTION: Adhesive will not cure if not properly mixed.
9. After a complete mixing, IMMEDIATELY pour the entire adhesive on the
subfloor and spread as soon as possible. DO NOT allow the mixed
adhesive to remain in the container. Spread the adhesive, in 3 foot wide
sections, as close to but not over your chalk lines. If you occasionally cross
the line with your trowel, a (1/16” x 1/16” square notched with 1/16” flats)
when spreading adhesive, do to be concerned. Any adhesive over the
