HOW TO PAVEVENEER STONE INSTALLATION TIPS

INSTALLATION TIPS
Working with stone veneers can be a satisfying experience and crafting a simple stone
wall is easily within the reach of your stonemason, landscaper or average DIYER
Preparing surface for stone cladding
Veneer Stone recommends that wall construction be in accordance with the relevant
Australian and Industry standards. The contractor must examine substrates and advise the
general contractor and architect of any existing conditions or surface contamination which will
require correction before work commences. Before starting, substrates must comply with
maximum allowable deflection criteria as called for by Australian Industry Standards or the
applicable local building code. All rough, uneven or “out-of-plumb” surfaces must be made
“plumb and true” to within 1/8” in 10’ (3mm in 3m) and 1/16” in 1’ Dry, dusty concrete or
masonry surfaces must be high pressure water washed and excess water removed just prior
to the application of adhesive materials. In some cases a primer may be needed which will
seal the suface and enhance the bond of the adhesive onto the substrate.
Preparing rendered surface for stone cladding
The surface of the wall must have a wood float finish. For steel trowelled finished surfaces
ensure that the surface is mechanically or chemically abraded prior to commencing tiling, in
this particular case. Render should be allowed to fully cure before tiling commences.
Preparing Brick work for stone cladding
Ensure all brick work internally/externally is rendered before installation.
Preparing tilt up concrete panels for stone cladding
All tilt up concrete slabs have to be mechanically grinded then cleaned using high pressure
water, ensuring that all curing compounds and release agents are completely removed prior
to commencing tiling. Ensure all surfaces are clean, dry and free from dirt, dust, grease, oil,
wax, curing compounds and any loose contaminating materials which may affect the bond of
the adhesive onto the substrate.
Mechanical fixing of stone cladding
In some cases mechanical fixing may be necessary. If in doubt please contact your engineer
or seek advice from laticrete on 1800 331 012
Installing stone cladding over expansion and control joints
Existing joints in subsurface must be carried through the veneer work and must conform to
architectural details. Expansion joints must be installed where veneer abuts restraining
surfaces, such as perimeter walls, curbs, columns, corners, etc. Expansion joints must be
installed at all “changes of plane” in the veneer work. Refer to AS3958.1-2007 (current year)
for industry recommendations.
Waterproofing and crack suppression membrane
Install Laticrete hydro ban in all wet areas and over all non-structural cracks (≤1/8” or 3mm) in
the substrate(s) before veneer stone is installed. Laticrete hydro ban is to be installed in
accordance with the Laticrete written installation instructions. Refer to Laticrete DS663.0 and
DS663.5 for complete information.
Cold weather note
The curing of installation materials is retarded by low temperatures and finished work should
be protected for an extended period of time. Typically, for every 18 ºF below 70 ºF (10 ºC
below 21 ºC), installation materials take twice as long to cure.
Product selection/Variation in stone veneers
Colour, size, shape and texture variation is an essential aspect of a natural stone wall. Lay
out and mix boxes of stone to ensure you gain this look. The visual effect will be enhanced by
an overall natural mixed presentation
