Specifications are subject to change without notification. The results shown are typical but reflect the test procedures used. Actual field performance will depend on installation methods and site conditions

Surface Preparation:
All surfaces should be between 40° F(4°C) and 104° F(40°C) and structurally sound, clean and free of all dirt, oil, grease, loose peeling paint, laitance, concrete sealers or curing compounds

Check the surface to be true to plumb. All slabs must be plumb and accurate to within"" ""¼" (6mm) in 10 ft(3m). Rough or uneven concrete surfaces should be smooth.

Dry, dusty concrete slabs or masonry should be dampened and excess water must be swept off. Installation may be made on a damp surface. New concrete slabs shall be damp cured and 28* days old before application.

*No minimum cure time for concrete slabs when thin-set mortar is mixed with latex additive. Expansion joints shall be provided through the tile work from all construction or expansion joints in the substrate. Do not cover expansion joints with thin set mortar. Follow ANSI Specification AN-3.8 "Requirements for Expansion Joints"or TCA Detail EJ171 "Expansion Joints". For tile installation over Cement Backer Board: follow TCA installation details W244.

Mixing:

Place clean, potable water into a clean mixing bowl. Add LATICRETE® 325 High Flex powder into the mixing bowl. Use approximately 5.5 – 6L of water for 20 kg of powder.

Mix by hand or with a slow-speed mixer to a smooth, trowelable consistency. Allow adhesive to slake for 5 minutes. Adjust consistency if necessary

* Contact MYK LATICRETE technical services for large format tile or stone installations on exterior surfaces.

Designed especially for interior and exterior floor and wall installations of all types of ceramic tile, vitreous/vitrified, semivitreous tile, glass mosaic tiles, precast terrazzo, - and natural stones over concrete and on a variety of substrates. Good underwater shear bond allows this product to be used for wet areas like swimming pools, saunas, water bodies and washrooms. It be used for tile on tile applications & also as a slurry bond adhesive in wet on wet applications

a) Tile/Stone

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. Use the proper sized notched trowel to ensure full bedding of the tile. Spread as much adhesive as can be covered with tile in 10 minutes. Back butter large format tiles (> 12"" "" x12"" "") to provide full bedding and firm support. Place tiles into the wet, sticky adhesive and beat in using a beating block and rubber mallet to imbed tile and adjust the level. Check adhesive for complete coverage by periodically removing a tile and inspecting bedding adhesive transfer onto the back of the tile. Use of MYK Laticrete spacers is APPLICATION: recommended to provide grout joints between tiles/stones. The joint width shall be as per the recommendation of the architect/engineer. Remove the spacers when the adhesive is set firm.
