Installation Instructions

ADHESIVE INSTRUCTIONS
Read adhesive instructions on containers for care and clean
up. Perform an adhesive bond test with actual tiles and
adhesives prior to installation to determine adequate
performance.
LANDING TILE
VPI 503 One Part Adhesive is a solvent-free, acrylic
adhesive that is designed to permanently install
dimensionally stable rubber / vinyl stair well systems. VPI
503 rubber/ vinyl stair well system adhesive can be spread
over porous and non-porous surfaces free of moisture. It can
be used on all grades of concrete on above or below grade
in the absence of moisture, as well as approved suspended
wood floors (APA). This adhesive has excellent resistance to
plasticizer migration and sets to a tough permanent
bond. See adhesive label for detailed application
instructions.
One gallon covers 125-150 square feet using a 1/16” x 1/16”
x 1/16” square notch trowel
Cure time of 48 hours – 72 hours for heavy traffic and rolling
loads
EQUIPMENT REQUIREMENTS
12 x 12 LANDING TILES
• 25 ft retractable rule
• Retractable knife
• Spare blades
• Pencil
• Masking tape
• Trowel 1/16” x 1/16” x 1/16”
• Cardboard sheet to protect tiles
• Gundlach Airway #222 Hand roller or equivalent
LANDING TILE INSTALLATION
• Acclimate Landing Tile and adhesive for 48 hrs. at
a temperature of 70 degrees.
• For uneven substrates, use a leveling compound
for best adhesion.
• Center landing tile in landing area for uniformity.
• Make sure the rubber nosing is set and any
adhesive ooze is scraped from the substrate or
ledging could occur.
If the substrate is porous:
• Ensure substrate surface has been prepared
properly.
• Spread VPI 503 adhesive on substrate using
specified trowel. Allow the adhesive to flash off for
5 – 10 minutes.
• Use recommended trowel for proper spread and
coverage.
• Starting at the nosing laying full tiles from the step
to the back of the landing until all full tiles are laid.
• Fill in partial pieces of tile toward the walls
• Roll all landing tiles with a Gundlach Airway #222
hand roller or equivalent.
• Clean adhesive spills with mineral spirits and a
clean cloth.
• Cover landing walk area with cardboard to protect
tile during construction
• Let landing cure for 48 hrs.
If the substrate is nonporous:
• Spread VPI 503 adhesive on substrate using
specified trowel. Allow the adhesive to dry to the
touch. When you run your fingers across the
trowel ridges, the ridges should be pliable with
moderate finger pressure. From the time the
adhesive is dry to the touch there are 45 minutes
to lay the landing tile into position. Do not allow the
adhesive to dry too long as loss of adhesion
strength may occur!
• Use recommended trowel for proper spread and
coverage.
• Starting at the nosing lay full tiles from the step to
the back of the landing until all full tiles are laid.
• Fill in partial pieces of tile toward the walls
• Roll all landing tiles with a Gundlach Airway #222
hand roller or equivalent.
• Clean adhesive spills with mineral spirits and a
clean cloth.
• Cover landing walk area with cardboard to protect
tile during construction
• Let landing cure for 48 hrs.
