3.3 IFA PS-5000 Pressure Sensitive Vinyl Tile and Plank Adhesive
Description
& Data: PS-5000 adhesive is solvent-free, non-flammable, freeze/thaw stable, and nearly odor-free. It can be used where
other adhesives might present potential health risks. It is suitable for office buildings, hotels, hospitals, schools,
restaurants, nursing homes, etc. PS-5000 adhesive contains one or more micro-biocides to inhibit the growth of
mold and mildew. PS-5000 should be used to install Centiva Vinyl Products Event Series and Harmony Line.
(ULTRASTONE, ULTRAPLANK, PLANKWOOD, GOOD OLE WOODS, BAMBOO, RIVER ROCK, DESERT
DUNE AND SANDSTONE.) UNDER NO CIRCUMSTANCES SHOULD IFA PS-5000 BE USED FOR THE
CENTIVA CLASSIC SERIES. It spreads easily, exhibits quick grab, and has excellent resistance to moisture and
plasticizer migration. Only IFA adhesive is to be utilized for installing Centiva flooring.
Surface
Preparation: Use on grade, above grade, or below grade (if the floor covering is recommended for below grade installations).
May be used over plywood, concrete, terrazzo, steel, and well-bonded, wax-free floor coverings. Use a high
quality latex/Portland cement based-type patching compound to fill or level any irregular areas. Never sand
resilient floors; they may contain asbestos. The floor must be sound, dry, and free from dirt, dust, old
adhesives, grease, wax, or other foreign matter. Concrete floors must be fully cured, free from dust, moisture,
excessive alkalinity, curing agents, and excessive moisture vapor emissions (3 lbs. /1,000 SF/24 hrs.) On- and
below-grade concrete must have a satisfactory moisture barrier beneath the slab. Do not use PS-5000 where
moisture is present in the concrete sub-floor; moisture may retard or prevent the adhesive from setting. May
be used over old cutback adhesive provided that the old adhesive is removed and the floor is smooth.
Application: The adhesive, tile, and room should be maintained at a minimum temperature of 68-72 degrees F. for 48 hours
prior to, during, and after installation. For porous sub-floors apply the adhesive with a 1/16” x 1/16” x 1/16”
V-notched trowel; for non-porous sub-floors use a 1/32” x 1/32” x 1/32” V-notched trowel. Immediately after
spreading the adhesive, roll it with a short nap roller dampened with adhesive to flatten the adhesive ridges.
This procedure will ensure that the trowel notch pattern does not telegraph through to the finished floor.
When using the “wet method” of installation test the adhesive to see if it has “strings” and is moist to the touch
before installing the floor covering. Check periodically to make sure there is full transfer to adhesive to the
back of the floor covering. When using the “tacky” method of installation, allow the adhesive to become tacky
before beginning the installation (adhesive should not transfer to the finger when touched). That set-up time
will vary with the temperature, humidity, and porosity of the sub-floor. To test, touch the adhesive lightly; if it
does not transfer to your finger, proceed with the installation. Place the tiles into the adhesive within two
hours of spreading. (Place carefully and accurately because the tiles cannot be repositioned easily). Within an
hour of installation roll the entire floor with a 100 lb. roller. Roll at least twice, once in each direction. Restrict
heavy foot traffic or rolling loads for at least 24 hours.
Limitations: Store indoors only. Protect from freezing. Adhesive is freeze/thaw stable to 10 degrees F. Prolonged or
repeated freeze/thaw cycles should be avoided. Should adhesive freeze, allow to thaw at room temperature and
stir well before using. The finished installation must be protected from moisture and/or freezing for a minimum
of 48 hours.
Clean-up: Dried adhesive can be difficult to remove; take care to remove wet adhesive from the surface of the tiles before
it dries. Fresh adhesive can be removed with a soapy, wet cloth. DO NOT FLOOD. DO NOT USE
SOLVENTS AS CLEANING AGENTS. DO NOT ALLOW ADHESIVE TO DRY ON FLOOR
COVERING BECAUSE EFFORTS TO REMOVE IT MAY CAUSE DAMAGE TO THE FLOOR
COVERING.
Coverage: Approximately 220-260 square feet per gallon. Coverage will vary with the type of floor covering and job
conditions.
