Exterior Substrates
Please consult LATICRETE Technical Services 800.243.4788, Ext 1235 for approval prior to use for all exterior applications. Maximum height restriction of 30' (9.1 m) applies.
Concrete (poured, pre-cast, tilt-up)
n
- Concrete must be minimum 6" (15 cm) thick reinforced
- Concrete must be minimum 3500 psi (24 MPa)
- Concrete must be minimum 28 days old prior to installation
CMU – double wythe walls only

APPROXIMATE COVERAGE
The coverage for LATAPOXY 310 Stone Adhesive will vary depending upon the amount of product required to plumb the wall. The chart below is based on 10% coverage of the area of each
tile or stone piece:
AVERAGE INCHES

1/4" (6 mm)
1/2" (12 mm)
1/2" Thick (12 mm)
Coverage is based upon square feet of stone installed.

LIMITATIONS
Surface temperature for application: 50°F (10°C) to 95°F (35°C).
n
For exterior applications, contact Technical Services 800.243.4788, Ext. 235 or support@laticrete.com for approval prior to use.
n
Slate and other fissile stone may delaminate due to the nature of their layered composition. Manufacturers of such stone must provide written approval to the installer that the stone is
n
suitable for their application.
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,
n
including concentrated loads, must not exceed L/360 for thin bed ceramic tile/brick installations or L/480 for thin bed stone installations or L/600 for exterior veneers where L=span
length (except where local building codes specify more stringent deflection requirements).
Do not apply LATAPOXY 310 Stone Adhesive onto veneers covered with any type of mesh backing. Grind off areas to receive adhesive before application.
n
NOTE: BEFORE USING PRODUCT, CONDITION MATERIAL TO ROOM TEMPERATURE (65°F/18°C ) FOR 24 HOURS TO ENSURE EASE OF MIXING.
COLD TEMPERATURES WILL REDUCE MIXING EASE.

SURFACE PREPARATION
3.1 All surfaces must be sound, clean, free of oil, waxes, frost, curing agents or contamination. Surfaces
treated with form release agents or other bond inhibiting contaminants must be mechanically scarified.
Concrete surfaces may be damp but with no standing water when application is made.
3.2 Clean and grind back of stone at areas to receive LATAPOXY 310 Stone Adhesive using a mechanical
wheel grinder with a diamond wheel/blade. Remove dust with a stiff brush, 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.
