Colors: Grey & White

Shelf Life

Factory sealed containers of this product are guaranteed to be of first quality for one (1) year* if stored off the ground in a dry area.

* High humidity will reduce the shelf life of bagged product.

Limitations

 For installations over exterior glue plywood, use with LATICRETE 333 Super Flexible Additive.

 For installations in submerged applications, mix with LATICRETE 3701 Mortar Admix. Wait 14 days after the final grouting  period before filing water features with water at 70°F (21°C)

 Do not install tile/stone when surface temperatures are below freezing (32°F [0°C]).

 Adhesives/mastics, mortars and grouts for ceramic tile, pavers brick and stone are not designed as replacements for waterproofing membrane; 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.

 DO NOT bond to particle board, luan, Masonite ® or hardwood surfaces.

Cautions

Consult MSDS for more safety information.

 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.

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

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

 For light–colored marble and stone use LATICRETE 220 Marble & Granite Mortar WHITE.

 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 of all dirt, oil, grease, paint, 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.  New concrete slabs shall be damp cured and 28 days old before application.  There is no minimum cure time for concrete slabs when mortar is mixed with latex additive.

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.  

1. 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.

2. Minimum construction for interior plywood floors.

SUBFLOOR:  5/8" (16 mm) thick exterior glue plywood, either plain with all sheet edges blocked or tongue and groove, over bridged joints spaced 16" (400 mm) o.c. maximum; fasten plywood 6" (150 mm) o.c. along sheet ends and 8" (200 mm) o.c. along intermediate supports with 8d ring-shank, coated or hot dip galvanized nails (or screws); allow 1/8" (3 mm) between sheet ends and  1/4" (6 mm) between sheets edges; all  sheet ends must be supported by a framing member; glue sheets to joints with construction adhesive.

UNDERLAYMENT:  5/8" (16 mm) thick exterior glue plywood fastened 6" (150 mm) o.c. along sheet ends and 8" (200 mm) o.c. in the panel field (both directions) with 8d ring-shank, coated or hot dip galvanized nails (or screws); allow 1/8" (3 mm) to 1/4" (6 mm) between sheets and 1/4" (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 

Mix one 50 lb (22.7 kg) bag of LATICRETE 220 Marble & Granite Mortar as follows: 5 to 5.25 qts (4.7 to 5 ℓ) of water or LATICRETE 3701 Mortar Admix; or 7.5 to 7.75 qts (7.1 to 7.3 ℓ) of LATICRETE 333 Super Flexible Additive. Place clean, potable water or a LATICRETE latex admix into a clean pail.  Add LATICRETE 220 Marble & Granite Mortar powder.  Mix by hand or with a slow speed mixer 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 substrate with flat side of trowel, pressing firmly to work into surface.  Comb on additional mortar with the notched side, use 1/2" x 1/2" (12 mm x 12 mm) or 3/4" (18 mm) half loop trowel. Spread as much mortar as can be covered with tile in 15–20 minutes.  Back butter large  > 8" x 8" (>200 mm x 200 mm) irregular backed tiles 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 to adjust level.  Check mortar for complete coverage periodically removing a tile and inspecting bedding mortar transfer onto back of tile.  If mortar is skimmed over (not sticky) remove and replace with fresh mortar. 

Grouting

Grout installation after a minimum of 24 hours curing time at 70°F (21°C). Grout with LATICRETE SpectraLOCK PRO Premium Grout, LATICRETE SpectraLOCK®† PRO Grout, LATICRETE PermaColor™ Grout mixed with water.

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 LATICRETE Thin-Sets with LATICRETE 101 Rapid Latex Admix.  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 hot temperatures.

Cleaning

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