Limitations
- For veneer installations using this product, consult local building code requirements regarding limitations and installation system specifications.
- Not for use directly over particle board, luan, Masonite® or hardwood floors.
- Adhesives/mastics or grouts for ceramic tile, pavers, brick and stone are not replacements for waterproofing membranes. When a waterproofing membrane is required, use a LATICRETE® Waterproofing Membrane.
Note: Surfaces must be structurally sound, stable and rigid enough to support ceramic/stone tile, thin brick and similar finishes. Substrate deflection under all live, dead and impact loads, including concentrated loads, must not exceed L/360 for thin bed ceramic tile/brick installations or L/480 for thin bed stone installations where L=span length (except where local building codes specify more stringent deflection requirements)
Cautions
- Consult SDS for more safety information.
- Some marbles and other stone have low flexural strength and may not be suitable for installation over wood floors.
- During cold weather, protect finished work from traffic until fully cured.
- Contains Portland cement and silica sand. May irritate eyes and skin. Avoid contact with eyes or prolonged contact with skin. In case of contact, flush thoroughly with water.
- Wait 14 days after the final grouting period before filing water features with water at 21°C
- DO NOT take internally. Avoid breathing dust. Wear a respirator in dusty areas.
- For white and light–colored marbles use 254 Platinum WHITE. For green marble, resin backed tile and stone and other moisture sensitive marbles and agglomerates, Use LATAPOXY® 300 Adhesive (refer to Data Sheet)
- Some marbles and other stone have low flexural strength and may not be suitable for installation over wood floors.
- Keep out of reach of children.

INSTALLATION
Surface Preparation All surfaces should be between 4°C and 32°C and
structurally sound, clean and free of all dirt, oil, grease, paint, concrete
sealers or curing compounds. Rough or uneven concrete surfaces should be made
smooth with Latex Portland Cement Underlayment to provide a wood float (or
better) finish. Dry, dusty concrete slabs or masonry should be dampened, and
excess water swept off. Installation may be made on a damp surface.
Concrete slabs must be plumb and true to within 6 mm in 3m.
Note: 254 Platinum does not require a minimum cure time for concrete slabs. Expansion joints shall be provided through the tile work from all construction or expansion joints in the substrate. Follow ANSI specification A108.01-3.7 “Requirements for Movement Joints: Preparations by Other Trades” or TCNA detail EJ-171 “Movement Joints—Vertical & Horizontal”. Do not cover expansion joints with adhesive.
- Installer must verify that deflection under all live, dead and impact loads of interior plywood floors does not exceed industry standards of L/360 for ceramic tile and brick or L/480 for stone installations where L=span length.
- Minimum construction for interior plywood floors. SUBFLOOR: 15 mm thick exterior glue plywood, either plain with all sheet edges blocked or tongue and groove, over bridged joints spaced 400 mm o.c.maximum; fasten plywood 150 mm o.c. along sheet ends and 200 mm o.c. along intermediate supports with 8d ring-shank, coated or hot dip galvanized nails (or screws); allow 3 mm between sheet ends and 6 mm between sheets edges; all sheet ends must be supported by a framing member; glue sheets to joints with construction adhesive.
UNDERLAYMENT: 15 mm thick exterior glue plywood fastened 150 mm o.c. along sheet ends and 200 mm o.c. in the panel field (both directions) with 8d ring-shank, coated or hot dip galvanized nails (or screws); allow 3 mm to 6 mm between sheets and 6 mm between sheet edges and any abutting surfaces; offset underlayment joints from joints in subfloor and stagger joints between sheet ends; glue underlayment to subfloor with construction adhesive. Refer to Technical Data Sheet 152 Bonding Ceramic Tile, Stone or Brick over Wood Floors for complete details.
Mixing
Place clean, potable water into a clean pail. Use approximately 4.0 – 4.2 L of
water for 20 kg of powder. Water mix ratio can be adjusted according to
surface temperature and type of substrate. When using to install Large Thin
Porcelain Tile use up to 4.2 L of water for 20 kg of powder.
Add 254 Platinum. Mix by hand or with a slow speed mixer to a smooth,
trowelable consistency. Allow adhesive to slake for 5–10 minutes. Remix with
out adding any more water or powder. During use, stir occasionally to keep mix
fluffy. DO NOT temper with water.
Application
Apply adhesive to the substrate with the flat side of the trowel, pressing
firmly to work into surface. Comb on additional adhesive with the notched side.
Note: Use proper sized notched trowel to ensure full bedding of the tile.
Spread as much adhesive as can be covered with tile in 15–20 minutes. Back
butter large tiles >200 mm x 200 mm to provide full bedding and firm support.
Place tiles into wet, sticky adhesive and beat in using a beating block and
rubber mallet to embed tile and adjust level. Check adhesive for complete
coverage by periodically removing a tile and inspecting bedding adhesive
transfer onto back of tile. If adhesive is skinned over (not sticky), remove
and replace with fresh adhesive.
Grouting
Grout installation after a minimum of 24 hours curing time at 21°C. Grout with
SPECTRALOCK®† PRO Premium Grout†, SPECTRALOCK PRO Grout†, PERMACOLOR Select NS
or PERMACOLOR Grout^^^
^^^United States Invention Patent No.: 6,784,229 (and other Patents) † United
States Invention Patent No.: 6,881,768 (and other Patents).
Cleaning
Clean tools and tile work with water while adhesive is fresh.
