Shelf Life

Factory sealed bags of this product are guaranteed to be of first quality for one (1) year from date of manufacture. High humidity will reduce the shelf life of bagged product.

Limitations

For exterior veneer installations using this product, consult local building code requirements regarding limitations and installation system
Not for use directly over particle board, luan, Masonite®or hardwood
Adhesives/mastics, mortars and grouts for ceramic tile, pavers, brick and stone are not replacements for waterproofing 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 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/720 for thin bed stone installation where L=span length (except where local building codes specify more stringent deflection requirements)

Cautions

Before using any LATICRETE product:

Consult SDS for safety
Some marbles and other stone have low flexural strength and may not be suitable for installation over wood
During cold weather, protect finished work from traffic until fully
DO NOT take
For white and light–coloured marbles use 257 TITANIUM™ White. For green marble, resin backed tile and stone and other moisture sensitive marbles and agglomerates, use LATAPOXY®300 Adhesive (refer to Data Sheet 1047).
For immersed installations use LATICRETE 254

INSTALLATIONS

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 and other backgrounds must be plumb and true to suit the format size being installed.

Note: 257 TITANIUM™ 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 AS 3958 for requirements for movement joints. Do not cover expansion joints with adhesives.

Mixing

Place clean, potable water into a clean pail. Use approximately 4.75L – 5L of water for 11 kg of powder. When using to install Gauged Porcelain Tile Panels/Slabs use up to 5.2L of water for 11 kg of powder (adhesive ridges should still stand without sagging). Add 257 TITANIUM to water. Mix 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

Mixing with PERMACOLOR® Select Colour Kits (257 TITANIUM White only)

Requires 2 PERMACOLOR® Select Colour Kits. (Each Colour Kit contains 2 individual colour packets, use all 4 colour packets) Place water in a clean mixing container. Remove colour packets from the cardboard container as well as the protective plastic sleeve. The internal bag is a water dispersible packet – when using the 11 kg bag of 257 TITANIUM, drop all colour packs directly in to water in clean mixing container. Mix with a drill mixer until pigment is dispersed evenly in container and the dispersible packet is no longer visible. Add 257 TITANIUM and mix as directed above. Please note that additional water may be necessary when using PERMACOLOR Select colour Kits.

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 notch trowel large tile and panels to provide full bedding and firm support. Place tiles into wet, sticky adhesive and beat in using a and rubber mallet and/or slide the tile back and forth 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; PERMACOLOR Select Grout; PERMACOLOR NS; or, PERMACOLOR Grout.

Note: Large panel and tiles will require longer time to set on non-porous surfaces and in colder site conditions.

Cleaning

Clean tools and tile work with water while adhesive is fresh.
