Using stone veneers could be a satisfying experience and crafting a simple stone wall is easily in the get to of your stonemason, landscaper or normal DIYER.
Stone cladding surface preparations
Veneer Stone suggests that wall surface construction be in accordance using appropriate Australian and Industry standards. The contractor must analyze substrates and advise the overall contractor and architect of any current conditions or surface contamination that may need correction before work commences. Before beginning, substrates must comply with maximum allowable deflection criteria as called for by Australian business Standards or even the relevant regional building signal. All harsh, irregular or “out-of-plumb” surfaces should be made “plumb and real” to within 1/8” in 10’ (3mm in 3m) and 1/16” in 1’ Dry, dirty concrete or masonry areas must be high-pressure water washed and extra water removed right before the use of adhesive products. Oftentimes a primer may be required that may seal the surface and boost the relationship of the adhesive on the substrate.
The top of wall surface must-have a wood float finish. For metallic trowelled completed surfaces make sure that the outer lining is mechanically or chemically abraded just before commencing tiling, within particular instance. Render should be allowed to fully heal before tiling commences.
Ensure all brick work internally/externally is rendered before set up.
Tilt-up concrete panels
All tilt up tangible slabs need to be mechanically grinded then cleaned making use of high-pressure water, making certain all curing substances and launch agents are entirely removed ahead of commencing tiling. Ensure all surfaces tend to be clean, dry and free of dirt, dust, oil, oil, wax, curing compounds and any free contaminating materials that might impact the bond regarding the adhesive onto the substrate.
In some instances mechanical rectifying might be required. If in question please speak to your engineer or seek advice from Laticrete on 1800 331 012.
Development and control bones
Existing joints in subsurface should be held through veneer work and must adapt to architectural details. Growth bones must be installed where veneer abuts restraining surfaces, eg perimeter wall space, curbs, columns, sides, an such like. Expansion bones should be set up anyway “changes of plane” in the veneer work. Refer to AS3958.1-2007 (current year) for industry tips.
Waterproofing and break suppression membrane
Install Laticrete hydro ban in most wet areas and over all non-structural cracks (≤1/8” or 3mm) into the substrate(s) before veneer stone is installed. Laticrete hydro ban is usually to be put in prior to the Laticrete written installation guidelines. Refer to Laticrete DS663.0 and DS663.5 for full information.
The healing of set up materials is retarded by low conditions and completed work is shielded for an excessive period of time. Usually, for almost any 18 ºF below 70 ºF (10 ºC below 21 ºC), installation materials just take twice as lengthy to cure.
Item selection/Variation in stones
Colour, dimensions, form and texture difference is an essential element of a normal stone wall. Formulate and combine cardboard boxes of stone to make certain you get this look. The aesthetic effect are enhanced by a broad normal presentation.
Installation of rock veneers & cladding
Before installation, make sure the backs of Veneer are clean of dust, laitance, free concrete crumbs and any excess film that may hinder relationship. Due to the wide selection of substrates we recommend you contact your regional glue provider or Laticrete on 1800 331 012 to get the best matched glue for the application.
- When the surface was ready prior to Australian business criteria, utilizing the level side of a trowel, firmly use glue into the substrate. Then, brush on additional mortar utilizing the notched side, utilize a 12mm x12mm notched trowel, with regards to the veneer size.
- For several veneers it is important to fill all grooves or irregular backing by buttering the rear of the veneer, this might be to deliver full bedding associated with veneer. Protect the entire straight back associated with the veneer not only the perimeter besides trowelling the adhesive onto the substrate.
- Position the veneer on the adhesive and conform to desired place. Buttered veneer should really be solidly worked onto the substrate and forced slightly to and fro to fully embed the veneer into the glue. Ensure the tiles tend to be set to the adhesive before it skins over. If the adhesive skins over take away the glue from the surface and re-apply fresh glue.
- Check out the adhesive for 100% coverage by occasionally the removal of veneers and examining the transfer associated with the glue onto the substrate.
Note; the scale and body weight for the veneer stone will be different. Conduct a small test location for non-sag overall performance. Due to job site circumstances and variations in finish product kinds; ledger panels, shims, wedges or spacers could be expected to maintain complete amounts and levels. Enable the set up to cure every day and night at 21ºC, prior to grouting. Extra glue must be cleaned from veneer surface with a clean, wet cloth or sponge, even though it is still fresh. The final sleep width for the glue should really be 6mm in this specific application.
Grouting and pointing bones
Allow the installation to heal for 24hours at 21 ºC before grouting /pointing bones. The Veneers should really be pre-sealed to ease grout removal and protect veneer surface finish and color. For interior installments, either a penetrating or topical sealer can be utilized. For outside installments, only use a penetrating sealer for exceptional durability.
- Use either a trowel and tuck pointing device or a mortar bag to put the pointing mortar.
- As soon as used, allow it to attain “thumbprint” hardness, then trowel, rake and/or brush into the desired finish. Joints must certanly be packed full and without voids and pits.
- Extra grout must be cleansed through the area associated with the veneers since the work advances, although the grout is fresh and before it hardens. Do not use acid or alkaline cleaners which could harm the surface of veneers.
Seal and protect stone cladding
The contractor has to take precautions to protect the finished work from damage by other investments. Protect installation from exposure to rain for no less than 7 days. Let the concrete to cure for no less than 7 days at 70 ºF (21 ºC) before hostile cleaning. For interior installations, either a penetrating or topical sealer can be utilized. For external installments, only use a penetrating sealer for exceptional durability. Whilst sealing the rock isn’t always needed it will probably protect veneer area finish and color. In the event that veneers tend to be installed near wet areas or places prone to salt assault, we advice dip sealing all veneers prior to set up.
