old adhesive, wax, grease, oil, insect repellents, etc. (See
Sub-Floor Preparation).
Cracks and uneven substrate surfaces must be filled with
approved patching compounds.
2. Preceding the installation, remove tile from any pallets
and place on a level flat surface. Tile and adhesive
should be kept at the EXPECTED OPERATING
TEMPERATURE OF THE SPACE or, ideally, at 70°F ±
5°, for at least 48 hours before application. This
temperature should be maintained during, and at least 48
hours after, application.
NOTE: Tile should not be installed above 85°F.
After acclimation, but prior to installation, wipe the back of
the tiles to remove any manufacturing residue or
contaminants.
3. Thoroughly stir Parts A and B separately with a rotary
motion, at the same time lifting from bottom. Use a
separate mixing paddle for each part, as provided, or a
mixing paddle on an electric drill.
4. Add Part B to Part A, making sure that the sides of the
Part B container are scraped clean. If mixing all materials,
ideally, the rims should be removed to allow material to
be scraped completely. When using partial mixes, pour
equal quantities of Parts A and B into separate containers
before combining.
Mix the two parts thoroughly for 4 minutes with a mixing
paddle on an electric drill at low speeds. DO NOT mix at
higher speed. This could cause the adhesive to start the
curing process and shorten the open time.
CAUTION: Adhesive should not be poured onto the
floor until Parts A and B have been completely mixed
together. Any unmixed portion applied to the subfloor
will not cure properly and adhesion will be affected.
5. After complete mixing, IMMEDIATELY pour ALL adhesive
on floor. DO NOT allow the mixed adhesive to remain in
the container. As soon as possible, use a 1/16” x 1/16” x
1/16” square notched trowel to spread adhesive. Do not
use excess adhesive, as this can cause oozing and
staining at seams.
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 when spreading adhesive, do not be
concerned, but note the area. Any adhesive over the
edge of the line must be scraped up before the next row
of tile is installed to avoid high edges (ledging).
NOTE: The adhesive will appear glossy when first
spread and will dull as it sets up. DO NOT allow the
adhesive to set up before installing the tile. Care
must be taken by the installer not to spread more
adhesive than can be worked appropriately within the
recommended time frame.
6. Lay flooring promptly after troweling (in no event more
than 30 minutes after mixing) to ensure proper transfer of
adhesive to the flooring.
7. Work off the tile whenever possible. When necessary to
work on the tile, avoid shifting material by using a
kneeling board and by cutting tile to butt tightly at all wall
junctions.
8. Roll and cross-roll the flooring with 150 pound sectional
roller immediately after flooring is laid. Roll a second time
one hour later. Inspect floor for raised edges one hour
after second rolling and roll a third time, if necessary. Use
hand roller while applying moderate to high pressure in
areas which cannot be reached with a large roller.
9. Adhesive on finished floor surface and residuals on tools
should be removed while adhesive is still wet, using cloth
dampened with soap and water. Alternatively, IPA or
denatured alcohol can be used for removal of partially
cured material.
10. Avoid traffic over finished floor for at least 48 hours after
installation.
11. Do not finish, wash, or service the floor for a minimum of
48 hours after installation to allow the adhesive to
properly cure.
VPI 520
VPI 520 is a one part acrylic pressure sensitive adhesive
(P.S.A.) approved for all types of sub-floors on or above grade
listed in these instructions.
SUBSTRATE REQUIREMENTS: MVER<5LBS, RH ≤85%,
pH of 7 - 11
TACK TIME: Can take from 30-90 minutes, depending on
conditions. Adhesive will change from milky to clear.
CLEAN UP: Remove uncured adhesive by washing with
water. Use a clean, damp towel and do not use excessive
water or adhesion failure can result. Cured adhesive can be
removed with mineral spirits. During initial maintenance, dry
buff these areas with a red pad on a low speed buffer to
restore the factory finish.
WORKING TIME: Once the adhesive has become tacky,
but dry, maximum open time is up to 3 hours. Site conditions
may decrease this, but they can be determined during the
bond test.
TROWEL TYPE: 1/16” x 1/16” Square Notched Trowel.
SURFACE TYPE: The adhesive is good for porous and
non-porous areas.
COVERAGE: 90 - 135 ft
2
/ gal, depending on porosity of
substrate, application style and environment. In applications
demonstrating spread rates that are less than 90 ft
2
, additional
adhesive should be purchased as required.
VPI 520 ONE PART PSA INSTALLATION:
1. All floors must be smooth, non-dusting, dry, and
completely free of paint, dirt, dust, sealers, curing agents,
