Install & Maint. PRT 15: 11-01-15 http://www.vpicorp.com/wp-content/uploads/2013/04/1S-Install-Maint-PRT-15.pdf
Excessive buildup or inconsistent spray pattern on
substrate may cause telegraphing.
Avoid extremely heavy application
6. If overspray occurs, it may be removed with a damp cloth
while the adhesive is still wet.
7. Allow adhesive to dry until there is no adhesive transfer
when lightly touched. High humidity and/or low
temperature increases tack time.
NOTE: Open time after application is about 4 hours
depending on a variety of factors. While open, ensure
that adhesive is not contaminated by dust.
8. Begin laying tile. Ensure proper alignment before
application of pressure and reposition as necessary
9. Roll the tile with a 150 lb. roller within 1 hour after
installation to complete the bonding process. After rolling,
the floor is ready for all access.
10. Do not finish, wash, or service the floor for a minimum of
48 hours after installation to allow the adhesive to properly
cure.
SEAMLESS INSTALLATIONS
PRT is available in 36” x 36” or 24” x 24” sections, square
edge or pre-grooved, for seamless installations. The 36” x 36”
or 24” x 24” sections have different requirements for site
acclimation, but are installed in essentially the same manner
as described under CONVENTIONAL INSTALLATIONS using
VPI 100 or VPI 520 with trowels, or with the application of
Spray Lock 6500.
SQUARE EDGE SECTIONS:
1. Remove tile from carton and store flat in stacks (not to
exceed 6” in height) at temperatures and durations called
for by the adhesive used. This allows tile to adjust to
room temperature. Tile will then lay flat and conform to
the contour of the sub-floor when installed.
2. Lay out field. For FLASH COVING, the last sections
should end at least 6” from the wall to allow space for use
of router and hot air welding tool around the room
perimeter. Follow the instructions under FLASH COVING
to cut and dry-fit appropriate material.
3. Apply the adhesive, per the instructions, and install the
field, making sure to properly roll and cross roll with the
sectional roller. Allow the adhesive to cure overnight.
4. Using a scrap piece of tile, set the router so that the blade
cuts a groove to a depth of approximately one half of the
thickness (~.060 in.) of the tile. Route all field seams in
one direction only, being careful to keep the groove
centered on the seam as closely as possible. Use a
chamfering plane to router cove pieces where the router
cannot be operated.
5. While seamless installations are usually flash coved, top
set cove base or other treatment may be used at the
floor-wall junction. In these instances, use a chamfering
plane to finish the groove close to the wall where the
router cannot be operated.
6. Preheat the hot air welding tool. Using the 4mm welding
nozzle, weld the bead into the groove.
7. Trial weld a few scrap pieces before starting on the floor
so that adjustments in the heat setting may be made.
NOTE: Beginners may find it easier to work with a
lower heat. However, with experience, welding will be
faster with a higher heat.
A lower heat is recommended for correcting mistakes
or welding in awkward places. A good weld is
achieved when a small amount of melted bead
overflows along the edges of the groove.
8. After the weld has cooled, shave off the excess bead with
a spatula. If the bead is shaved before it has cooled, it will
shrink below the surface of the flooring. Keep the spatula
sharp by periodic honing with a fine sharpening stone.
9. After welding and trimming all seams in one direction,
repeat the routing, welding, and trimming procedures on
all seams running in the other direction.
PRE-GROOVED SECTIONS:
When installing pre-grooved tile, use the same general
installation instructions as for square edge. Exceptions to
these general instructions are as follows:
1. Take extra 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. If adhesives in the groove have cured,
use the chamfering plane to remove all excess adhesive
that may have seeped into the grooves.
2. Weld and trim all seams in one direction only.
3. Use the chamfering plane to open each cross seam.
4. Weld and trim all remaining seams.
FLASH COVE INSTALLATIONS
Coving of tile up the wall eliminates accumulations of dirt and
bacteria at the floor-wall junction. CONVENTIONAL or
SEAMLESS INSTALLATIONS may be flash-coved. Additional
instructions for Flash Coving are available at
www.vpicorp.com, but the following highlights the procedure:
1. Install a suitable cove cap strip (either metal or plastic)
around the entire room. Exercise care so that the top of the
cove cap strip height is consistent. Use either flat-headed
nails or contact bond adhesive to cove capping.
2. Place a cove strip at floor-wall junction to support tile at the
bend.
3. When installing 12” x 12” tile, lay out the field so that 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 convenient distance in excess of
6” from the wall.
4. Install the field in accordance with the procedures listed
under either CONVENTIONAL or SEAMLESS
INSTALLATIONS, and allow the adhesive to cure for at
least 24 hours. This is critical for properly forming coving
and achieving a finished appearance.
5. Dry cut cove tile pieces to fit. Remove pieces and apply
adhesive to the exposed floor and wall. Install the pieces
and roll thoroughly with a hand roller. If VPI 100 adhesive
is used, do as large an area as practical to avoid repeated
mixing of adhesive batches. Seam weld after 24 hours, if
appropriate.
