edges of the line must be scraped up before the next row is installed to
avoid (ledging) or high edges.
10. Install tile immediately over the prepared epoxy adhesive surface. It is
essential that the specified trowel and roller be used. If the trowel notches
are too large, too much adhesive will be used. This will result in excessive
adhesive seepage at the seams and also will cause the tile to float and
shift. Clean up after installation is then very difficult. In addition, the seams
will be ledged making them very noticeable and dirt catcher as well. Any
delay in rolling the tile due to excessive adhesive seepage, will result in
poor adhesive transfer to the back of the tile and adhesion failure. The
trowel notches are worn or too short and the adhesive will be spread too
thin resulting in adhesion failures too.
WORK OFF THE TILE WHEN EVER POSSIBLE.
When laying individual tile, do not slide the tile in place. The correct
procedure is to place a corner of the tile in place next to the adjoining tile,
carefully guiding it in the proper position an set it in place. When necessary
to work on the tile, avoid shifting by using a kneeling board and by cutting
the tile to butt tightly at all wall junctions. Roll and cross roll the tile with a
150 LB. sectional roller immediately after the tile is laid. Roll a second time
and one hour later. Inspect the floor for raised edges one hour after a
second rolling, if necessary, roll a third time. Use hand roller in the areas
that can’t be reached with a larger roller.
DISCARD WORN TROWELS
Please note that using unapproved adhesive will void any Exclusive VPI
Warranty. Consult instructions for proper subfloor requirements before
opening any adhesive. Open time, working time and cure time will be
longer at lower temperatures, and will shorten at higher temperatures.
Ensure that the installation is well lit to allow effective examination of the tile
installed. If flash coving is desired, see special instruction under Flash
Coving.
ADHESIVE APPLICATION TYPE:
VPI 150 or VPI 165 is an integral component of the EDS control
system. The use of a non-VPI Conductive Adhesives will void
VPI’s Limited Warranty.
VPI 165 ADHESIVE:
Specially formulated so that it contains no solvents emitting zero VOC’s.
This adhesive is designed to permanently install VPI Conductive and
Statmate Static Controlled Flooring only.
CHARACTERISTICS: One part Acrylic adhesive should dry to the touch.
45 minute set up time. This makes it extremely important to roll floor as
recommended to avoid raised edges.
s
CLEAN UP: Soapy water followed by mineral spirits. Do not apply solvent
directly to the tile. Use moist cloth with mineral spirits.
SET UP TIME: About 45 minutes. Do not spread more than you can
install in that time.
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 of product.
SURFACE TYPE: Porous floor, once trowel, the adhesive should be
allowed to remain open (flash off) for 5-10 minutes before placing tiles on
the adhesive.
Non-Porous floor, allow the adhesive to dry to the touch so that there is little
or no transfer of adhesive to the fingers. Maximum open time: 45 minutes.
Exceeding the 45 minutes open time will lead to floor failures due to poor
adhesion.
COVERAGE: 90 - 135 sq. ft. per gallon depending on substrate
porosity, application style and environment. In applications
demonstrating spread rates that are less than 135 SF, additional
adhesive should be purchased as required.
MVER 5LBS or less, RH ≤ 85%, pH of 7 - 11
VPI 165 ONE PART ACRYLIC ADHESIVE INSTALLATION
INFORMATION:
1A. Before the beginning of the installation, remove cartons from the
pallets, and place on a flat floor surface at 70 degrees or at the
expected temperature of operation for a minimum of 48 hours.
1B. After acclimation, 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 cement
based patching compound.
4. Using mixing paddles provided or mixing paddles on an electric drill to
carefully stir.
5. ESD floors must be grounded every 2,000 square feet or each area if
less than 2,000 SQ. FT. SEE GROUNDING SET UP
REQUIREMENTS.
6. Use a 150 LB three sectional flooring roller, roll and cross roll the tile
immediately after it has been installed, and then repeat approximately
1 hour later. Use a hand roller in those areas that cannot be reached
by the larger roller.
7. Lay out the field so that the last section ends at least 6” from the wall
to allow space for use of the router and the how air welding tool
around the room perimeter.
SEAMLESS INSTALLATION:
Conductile and Statmate are available in 36 x 36 or 24 x 24 inch tiles.
Square edge or pre-grooved, for seamless installations. The 36” x 36” or
24” x 24” sections are installed in essentially the same manner as described
under Adhesive Installation information.
1a. Dry cut all cove pieces to fit as described under FLASH COVING, and
install them. Roll thoroughly with a hand roller.
1b. Install the field, making sure to install copper grounding strips at the
designated grounding connections. Make sure that the tile is rolled
and cross rolled with the proper sectional roller.
1c. Using scrap tile set the router height to half the thickness (.060). You
need to router in one direction and center the groove over the seam.
Use Chamfering plane to router the cove pieces where a router cannot
be operated.
2. Preheat the hot air welding tool. Use the 4mm welding nozzle. Weld
the bead into the groove. Trail weld on scrap tile to adjust the bead
melt and flow. Beginners use a lower heat, more experienced higher
heats for faster production.
3. Trim all seams in one direction, repeat the routing, welding, and trim
procedure on all seams running in the other direction.
4. While seamless installations are usually flash coved, tip set cove base
or other treatments may be used at the floor-wall junction. In these
instances, use a chamfering plane to finish the groove closest to the
wall where the router cannot be operated.
PRE-GROOVED SECTIONS:
A. Take care to minimize adhesive seepage at the seams. Any adhesive
allowed to remain in the grooves could prevent the vinyl bead and
flooring from fusing together properly.
B. After the adhesive has set up overnight, use the chamfering plane to
remove all excess adhesive that may have seeped into the grooves.
C. Weld and trim all seams in one direction only.
D. Use the chamfering plane to open each cross seam.
E. Weld and trim all remaining seams.
FLASH COVING:
Coving tile up the wall eliminates accumulation of dirt and bacteria at the
floor wall junction. This procedure can be used with either Conventional or
Seamless installations. The following steps are recommended:
A. Install cove cap inside and outside corners. Then install a suitable
cove cap strip (either metal or plastic) around the entire room.
Exercise care so that the top of the cove cap are at the same level.
Use either flat headed nails or contact bond adhesive to fasten
corners and cove cap strips.
B. Place a cove stick at floor-wall junction to support the tile at the bend.
Radius of cove stick should be at least 7/8” and must have the same
radius as the metal corners.
C. When installing 12” x 12” tiles, lay out the field so it ends
approximately 6” from the wall. When 24” x 24” or 36” x 36” sections
are used, the field can be laid out so that the last section ends at any
distance that is greater than 6” from the wall. The distance from the
edge of the field to the cove cap strip must be less than the width of
the coved pieces since variation in the floor and wall will always
necessitate cutting the coved pieces so that a tight fit can be
achieved.
