Limitations

 Use LATAPOXY® 300 Adhesive for installing green marble, water sensitive stone and agglomerate and resin backed tile and stone.

 For veneer installations using this product, consult local building code requirements regarding limitations and installation system specifications.

 Use a white thin set mortar when installing white or light-colored stone.

 Adhesives/mastics, mortars and 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 (see Section 10 FILING SYSTEMS).

 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 MSDS for more safety information.

 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 70°F (21°C).

 Do not take internally. Silica sand may cause cancer or serious lung problems. Avoid breathing dust. Wear a respirator in dusty areas.

 Keep out of reach of children.

INSTALLATION

Surface Preparation

All surfaces should be between 40°F (4°C) and 90°F (32°C) and structurally sound, clean and free from all dirt, oil, grease, paint, laitance, concrete sealers or curing compounds.  Rough or uneven concrete surfaces should be made smooth with LATICRETE 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.  

Note: Latex portland cement mortars do not require a minimum cure time for concrete slabs.  All slabs must be plumb and true to within 1/4" (6 mm) in 10 ft (3 m).  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 mortar.

Mixing

Stir LATICRETE 211 Powder thoroughly before use. Use approximately 1.5 gallons (6 ℓ) of LATICRETE 4237 Latex Additive to 50 lbs (22.7 kg) of LATICRETE 211 Powder and place LATICRETE 4237 Latex Additive in a clean plastic pail.  Do not dilute. Add LATICRETE 211 Powder to LATICRETE 4237 Latex Additive and mix to a smooth, trowelable consistency.  Allow mortar to slake 5–10 minutes.  Adjust consistency if necessary.  Remix and apply with the proper sized notched trowel.

Application

Apply mortar to the substrate with the flat side of the trowel, pressing firmly to work into surface.  Comb on additional mortar with the notched side.

Note:  Use the proper sized notched trowel to ensure full bedding of the tile.  It is essential that enough mortar is used to completely cover the back of the tile with a minimum 3/32" (2 mm) to 1/8" (3 mm) uniform thickness.  Spread as much mortar as can be covered with tile in 15–20 minutes.  Back butter large tiles >8" x 8" (200 mm x 200 mm) to provide full bedding and firm support.  Place tiles into wet, sticky mortar and beat in using a beating block and rubber mallet to embed tile and adjust level.  Check mortar for complete coverage by periodically removing a tile and inspecting bedding mortar transfer onto back of tile.

Grouting

Grout installation can occur after a minimum of 24 hours curing time at 70°F (21°C).  Grout with LATICRETE PermaColor™ Grout or, LATICRETE 1500 Sanded Grout or LATICRETE 1600 Unsanded Grout mixed with LATICRETE 1776 Grout Enhancer.  For maximum stain resistance use LATICRETE SpectraLOCK®† PRO Grout.

†United States Invention Patent No.: 6881768 (and other Patents)

Cold Weather Note: The setting of portland cement mortars and grouts are retarded by low temperatures.  Protect finished work for an extended period when installing in cold weather. For faster setting mortar use LATICRETE 254 Platinum Rapid. Do not set tile when surface temperature is below freezing or when substrate is frozen.

Hot Weather Note: The evaporation of moisture in portland cement mortars is accelerated by hot, dry conditions.  Apply to dampened surfaces and protect freshly spread mortar and finished work when installing in temperatures over 95°F (35°C).

Cleaning

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