Average Inches
(or millimeters) Out of Plumb		 LATAPOXY® 310 Thickness Approx. Coverage/
10 Liter Unit
Plumb Wall 1/8" Thick (3 mm) 300–325 ft2 (27–30 m2 )

1/2" (12 mm) 1/2" Thick (12 mm) 75–80 ft2 (7–7.5 m2 )

Cartridge Pack Coverage

One carton (15 cartridges) will yield approximately 150 ft2 (14 m2 ) with 1/4" (6 mm) thick dabs, or 300 ft2 (27 m2 ) with 1/8" (3 mm) thick dabs when covering 10% of the veneer surface.

Shelf Life

Factory sealed containers of this product are guaranteed to be of first quality for two (2) years if stored at >32°F (>0°C) to <110°F (<43°C).

Limitations
  • Surface temperature for application: 50°F (10°C)—95°F (35°C)
  • For exterior applications, contact Technical Services at 1.800.243.4788, ext. 235 or support@laticrete.com for approval prior to use
  • Sandstone, slate and fissile stones are not recommended veneers and should not be used with LATAPOXY 310 Stone Adhesive. These stones and other porous stones may delaminate or break apart due to the nature of their porous and layered composition
    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
Cautions

Consult MSDS for more safety information.
  • Keep out of reach of children
  • LATAPOXY 310 Stone Adhesive has a slight, non-hazardous odor
  • During cold weather, protect finished work from traffic until fully cured
  • LATAPOXY 310 Stone Adhesive Part A is corrosive to eyes and skin before curing. Avoid contact with eyes and or prolonged contact with skin. In case of contact, flush thoroughly with water
  • Consult local building code for requirements

INSTALLATION

Preparation

Store resins at room temperature (>70°F [>21°C]) for 24 hours before using. All surfaces must be sound, clean, free of oil, waxes, frost, curing agents, form release agents or other bond inhibiting contaminants. All substrates must be clean and dry when application of LATAPOXY 310 Stone Adhesive is made. 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.
Finished veneers equipped with any type of resin, mesh, epoxy or fiberglass backing must be ground down to the bare stone in those areas to receive LATAPOXY 310 Stone Adhesive.
Clean and grind back of stone at areas to receive the LATAPOXY 310 Stone Adhesive spots using a mechanical wheel grinder with a diamond wheel/blade. Remove dust with a stiff brush and wipe entire surface. Using a damp sponge (not wet), wipe the tile or stone to remove any particles or remaining dust to ensure a clean direct bond and that all ground material is removed. Wipe dry with a clean cloth, then apply LATAPOXY 310 Stone Adhesive.

Recommended Guidelines for Spot Bonding Stone:

(Please consult your Local Code for actual code compliance)
  1. Size—for tile or stone
    Maximum Thickness: 2"–720 in2 (50 mm–4645 cm2 ) in area.
    For >720 in2 (4645 cm2 ) contact LATICRETE Technical Service.
  2. Module Weight—for tile or stone
    Weight 15 lbs/ft2 (73 kg/m2 ) unless approved by an engineer.
Exception—Adhered veneered units weighing less than 3 lbs/ft2 (1.4 kg/m2 ) shall not be limited in dimension or area.
Note: Always check with the tile or stone factory to make sure the tile or stone is suitable for vertical and exterior (if applicable) installations.

Mixing

Combine equal volumes of LATAPOXY® 310 Stone Adhesive Part A and Part B (1:1 mix ratio by volume). Mix until uniform in color; no swirls. Small quantities can be mixed with a putty knife or margin trowel. Larger quantities can be mixed with an electric drill mixer (low speed). Cartridge packs are designed for use only with the LATAPOXY 310 Cordless Mixer.

Application

Apply dabs evenly distributed on back of the stone or tile; 5 dabs minimum, 1 in each corner and 1 in center. Cover at least 10% of the area of each piece. Finished dab thickness must be a minimum of 1/8" (3 mm), maximum of 1" (25 mm).

Approximate dab diameter required to achieve 10% coverage with 5 dabs:
Tile Size Dab Diameter
12" × 12" (300 mm × 300 mm) 2" (50 mm)
24" × 24" (600 mm × 600 mm) 4" (100 mm)
36" × 36" (900 mm × 900 mm) 6" (150 mm)
After installation of LATAPOXY 310 Stone Adhesive onto the veneer, install onto substrate and adjust for plumb and level.

Joint Treatment

Exterior Applications:
Use LATICRETE® Latasil™ to treat all joints. Refer to Data Sheet 6200.1 for further instructions.

Interior Applications:

The following LATICRETE products may be used:
  • LATICRETE SpectraLOCK® PRO Grout
    United States Invention Patent No.: 6881768 (and other Patents)
  • LATICRETE 1500 Sanded Grout or LATICRETE 1600 Unsanded Grout mixed with LATICRETE 1776 Grout Enhancer
  • LATICRETE Latasil
  • LATICRETE PermaColor™ Grout
Test area to ensure proper filling as narrow veneers and wider gaps behind the veneer may not allow for joint filling with an epoxy or cement grout.
Note: Control, expansion or other movement of joints must be treated with a flexible sealant.

Cleaning

Clean tools and work while epoxy is fresh, using warm water. Detergent or soap can be added to the water for easier cleaning.
