Install & Maint. PRT 15: 11-01-15 http://www.vpicorp.com/wp-content/uploads/2013/04/1S-Install-Maint-PRT-15.pdf
CONVENTIONAL INSTALLATIONS
GENERAL
The area to receive flooring should be fully enclosed, weather
tight, with the permanent HVAC system set and maintained at
a minimum temperature of 65° F for 48 hours prior to, during
and at least 48 hours after installation.
Avoid exposure of tile to excessive heat, such as direct
sunlight, until adhesive has completely set. Avoid any traffic
over finished floor for at least 72 hours after the installation.
Install PRT Flooring in accordance with the following
procedures using only VPI 100, VPI 520 or Spray Lock 6500
adhesives. Please note that using unapproved
adhesives will void the VPI PRT warranty. All three
listed adhesives can be used to install PRT tiles on porous and
non-porous substrates.
Adhesive usage varies depending on whether the substrate
floor is porous or non-porous. It is essential that the sub-floor
is tested to verify whether the concrete is porous or non-
porous prior to the installation of the floor. To test, place
several droplets of water in numerous locations within the
installation area. If water is absorbed in less than 45 to 60
seconds, concrete is to be considered porous. If water remains
beaded or is not absorbed into the concrete within this time
frame, the substrate is to be considered non-porous and may
have had a surface coating applied such as curing compound
and or a sealer.
Excess Adhesive Removal: Isopropanol (IPA), denatured
alcohol and/or a mild abrasive cleaner such as Soft Scrub ®
work well to remove adhesives, especially before they cure.
Using a dry cloth and IPA, wipe up adhesive that has oozed
from seams or spills immediately followed by Soft Scrub to
remove staining. Do not use cleansers containing amines, as
yellowing may occur. Rinse well with water.
EQUIPMENT
It is essential that the specified trowel and roller be used.
Worn trowels should be discarded. NEVER re-notch a
trowel. 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 the installation is then very difficult. In addition, the
seams will be ledged making them very noticeable and dirt
catchers as well.
If you delay rolling the tile because of excessive seepage, the
adhesive will not be adequately transferred to the back of the
tile causing an adhesion failure. If the notches are worn on the
trowel, the adhesive will be spread too thin resulting in
adhesion failure.
LAYING TILE
When laying individual tile, do not slide tile into place. The
correct procedure is to place a corner of the tile in place next
to the adjoining tile, carefully guide it into proper position and
set it in place.
WORK OFF THE TILE WHENEVER POSSIBLE. When
necessary to work on the tile, avoid shifting by using a
kneeling board and by cutting tile to butt tightly at all wall
junctions.
Roll and cross roll the tile with 150 pound sectional roller
immediately after the tile is laid. Roll a second time one hour
later. Inspect the floor for raised edges one hour after the
second rolling, if necessary, roll a third time. Use a hand roller
in areas that cannot be reached with a large roller.
IMPORTANT! ANY ADHESIVE AT SEAMS OR ON
FINISHED SURFACES OF TILE MUST BE REMOVED
WHILE THE ADHESIVE IS STILL WET.
Using Adhesives: Read the instructions for proper sub-floor
preparation before opening the adhesive. If the installation will
be flash coved, see special instructions under FLASH
COVING.
All adhesive, floor tile and sub-floor (i.e. concrete slabs) should
be conditioned at the expected operational temperature and
ambient humidity level. Maintain these levels at least 48 hours
before and after the tile is installed using VPI adhesives, and
72 hours before and after the tile is installed using Spray Lock.
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 and the overall installation.
VPI 100
VPI 100 is a two-part epoxy adhesive approved for all types of
sub-floors below, on or above grade. VPI 100 is recommended
when high sheer, high traffic and high loads are expected.
SUBSTRATE REQUIREMENTS: MVER<5LBS, RH ≤85%,
pH of 6 - 9
TACK TIME: Epoxy adhesives are different from other
adhesives; they do not develop tackiness as they set 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.
WORKING TIME: Maximum working time is about 30
minutes. Exceeding the 30 minutes open time will lead to floor
failures due to poor adhesion - do not spread more than you
can install in that time. Appearance is glossy when first spread
and dulls as it sets up.
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 SF,
additional adhesive should be purchased as required.
VPI 100 2-PART EPOXY INSTALLATION:
1. All floors must be smooth, non-dusting, dry, and
completely free of paint, dirt, dust, sealers, curing agents,
