Our stone cladding systems also offer incredible versatility, from sleek, geometric tiles such as Aksent™ and Planc™, to modular, large-scale format formats including XLX Rock Panel™ and Rustik™. With such a diverse range, it’s critical to have a thorough and well-understood methodology for both installation and aftercare.
 
Our many years as leading UK stone cladding suppliers means we have developed an extensive, highly effective technical application guide based on real-world feedback from our commercial partners and our approved materials distributors.  It is really important, whether it is on a commercial scale or a small private dwelling, that your project is protected by reputable, long-standing warranties and guarantees – Norstone have partnerships with our preferred suppliers, Laticrete International and Knauf.
 
When installed to the technical specifications and using the correct substrates, the combined Knauf / Laticrete warranty is good for a staggering 25 years! Because of these warranties, many of the UK’s leading architects and interior designers work closely with Norstone before choosing a stone cladding range suitable for their project.
 
Design projects that feature stone cladding surfaces can differ greatly, due to technical considerations such as proximity to the sea, cliff top locations, etc. Certain weight restrictions may mean timber or steel frames are required, this often requires working closely with our partners to develop a suitable system warranty that satisfies the most discerning architect, but more importantly, you.
 
We will not only sell you lifestyle choices, but more importantly, our natural stone cladding ranges are backed by warranties which will stand the test of time. Remember, stone cladding and warranties go hand in hand at Norstone.

STEP 1
We recommend you apply LavaSeal prior to installation and grouting. Start by sealing the Lavastone panels with a lint free cloth or similar, one coat, when dry apply second coat.

STEP 2
Ensure that you have completely covered the surface with the first coat, as shown. Wait to dry.

STEP 3
Now dry and ready to be adhered to substrate, no colour change when dry.

STEP 4
Screeded substrate with 6mm notched trowel, a thin bed is required to stop any adhesive squeezing through the gaps when the stone is applied. The compressed bedding adhesive should be less than 10mm or less. Also recommended, a thin bed applied to back of Norstone tile as well.

STEP 5
Applying the Lavastone and using a grout float to pat it down on the surface to ensure full contact.

STEP 6
Fixed Lavastone waiting for adhesive to dry and then grouted.

STEP 7
Applying the grout, you can see why it would be impossible to avoid filling the holes and why it was necessary to pre-seal.

Step 8
Cleaning off excess grout. This is a much more simple process when working with a pre-sealed surface.

Step 9
The panel shows the visual difference with once section completed with light grey grout and the other done in dark grey grout.

IN SUMMARY...
With Lynia™, and other stone cladding panels requiring grouting, it is our recommendation that you pre-seal as above. This will make sure the grouting material cannot become permanently stuck to the main surfaces of the panels and makes the cleaning up process much more straightforward.
