Installation

Recommendations and references to the usage of the Z-Stones natural stones


Use:

Usually for interior wall facings (avoid directly wet areas), and outdoor use.

Preparation:

  • Roughen the back surface (which also shows the natural nuanced colour play of the various Quarzite and slate types).


Substrate:

  • Must be workable, dust-free, firm and even.
  • Completely level off and roughen extremely uneven / smooth surfaces.
  • On mineral type surfaces (and hard foam carrier systems) an undercoat not required.


Cutting:

Take the same precautions for health and safety as applicable to normal tiling and normal handling of stone/slate product products. Pay attention to information provided with the materials. If in doubt, consult a suitably qualified professional.

  • For example use a wet cutter or an angle grinder (use exclusively a natural-stone saw blade).
  • Holes can be cut with a hole-saw /diamond drilling bit and water cooling attachment (start drilling on the back, then on the front complete the hole boring) or with a high-pressure water jet saw.


Placing:

  • To avoid inconsistencies in the finished presentation: Mix the material by installing in parallel from several packages/pallets.
  • A white thin-bed rapid setting hydraulic polymer-modified bedding mortar (C2 FT or C2 FTE in accordance with EN classification) is used.
  • Apply adhesive with a 10mm toothed trowel.
  • Align the first/lowest row with a spirit level.
  • Coat the back of the stone panel and the wall with around 10mm of flexible adhesive then transfer the stone panel fully flat onto the wall/adhesive bed (floating and pressing to achieve a cavity-free installation according to DIN 18299).
  • Install the remaining stone panels, without gaps, one above the other.
  • Where corner areas are to be covered, first install corner stone panels in the respective rows then subsequently install the "normal" stone panels.
  • A mechanical reinforcement is recommended from around 2m height.
  • Immediately clean possible adhesive residue from the surface.
