Additional information regarding placement techniques:


Installation techniques: Not adhering to stabilized sand

  • Placement of polythene foil on concrete floor.
  • Stabilized sand bed thickness 2-5cm
  • Mortar layer has a thickness between 1.5 – 3cm. The amount of mixing water must be minimal, preferably add a product to promote adhesion and reduce water.
  • Coat the underside of the tiles with a product that slows down moisture penetration, tile thickness 1.5 cm minimum since they are beaten in mortar (see principle sketch).


Adhesive floor, glued to screed

  • Placing a polyethylene film under the screed.
  • Screed; a stainless reinforcement net is placed in the screed at least 50mm thick, when installing underfloor heating 75mm, unless one uses stud plates. Waiting time 1 week per cm of thickness.
  • Adhesive or mortar adhesive, adhesive only suitable for tiles with the same thicknesses as unevenness is minimal, mortar adhesives are dry mixtures with minimal water addition, compulsory for stain-sensitive materials !!!! (see sketch of principle).


Bonded floor in mortar bed

  • Placement of a polyethylene foil under the screed.
  • Use a stainless steel reinforcement net in the screed. Screed at least 50mm thick, with underfloor heating 75mm.
  • Mortar layer has a thickness of 1.5 – 2cm, to reduce the risk of staining, limit the amount of mixing water, add product to promote adhesion and to reduce water. Provided with edge and expansion joints, coat the bottom of the tiles with product to slow down moisture transmission. (see sketch of principle).


Adhesive floor with mortar or adhesive on a paved surface

  • Only apply this method if you have to tile directly on the supporting floor in connection with height only possible if there are no pipes in the supporting floor.
  • The mortar layer has a thickness between 1.5 – 2cm, limit the amount of mixing water, add product to promote adhesion and reduce water.
  • With mortar adhesive or glue, only suitable for tiles of equal thickness and if unevenness is minimal, mortar adhesives are dry mixtures with minimal water addition. (see sketch of principle).


Finishing walls in normal and damp rooms

  • The surface must be flat and sufficiently dry. In damp rooms, use sealing joints at all sanitary connection points and drains, placing sealing strips under tiles to obtain a watertight whole.
  • Placement of tiles with normal mortar adhesive and joints with traditional joint mortar in normal living areas.
  • Tiling in damp areas with moisture-resistant tile adhesive, joints with appropriate moisture-resistant products, when connecting corners, apply external corners, inside corners, shower connections and elastic acid-free joints. (see sketch of principle).


Stair cladding

  • Stair treads can also be made of natural stone, even self-supporting steps can be made of natural stone.
  • Fixing for structural concrete with mortar or adhesive.
  • Steel natural stone adhesive adhesives according to adhesive advice specified by the manufacturer
  • Adhesive flexible bonding of natural stone.
  • In the beginning, a staircase will still deform, transition to the stair and storey floor provided with a movement joint, always with a non-slip strip on each step.


Kitchen countertops

The use of stains and acids in the kitchen must be taken into account, the natural stone must be suitable for such applications, only the use of non-calcareous materials is recommended. Always use acid-free mounting kit for natural stone.


Outdoor terraces in general

It is important that water is properly and quickly drained from the surface. Always slope the floor slightly (slope)


  • The water drainage from the underground takes place by means of a drainage mat or possibly crushed stone. Drainage is applied around the terrace.
  • Tiles are under great exposure of temperature fluctuations, expansion and shrinkage will be high, thickness of the stone to be determined by the expected load on the stone.
  • The bottom layer consists of a draining crushed stone 20-30cm, on top of which a draining granular concrete, above which a stabilized sand bed or screed.
  • If the concrete layer consists of non-draining concrete, lay it at a slope of 2 percent, always take measures by placing a drainage mat on top of the concrete layer.
