POINTS TO CHECK!

• After delivery, protect the natural stone properly against rain, wind and frost. Best to put inside.

• Mix the tiles before placing in order to obtain a nice distribution of colors and shades.

• Never place the natural stone tiles against each other. A natural stone tile must can expand and contract.

• The tile floor must have a slope of 1.5%. Make sure that this slope runs away from the house to allow the water to drain.

• provide100% contact area between the tiles and the substrate so that no hollow spaces are created under the tiles.
  Place the natural stone tiles with glue or a improved laying mortar.When gluing always comes with a double bondingworked.
  Both the substrate and the underside of the tile are covered!
  Use the correct trowel. Minimum pitch of 12mm. The bigger the tile, the bigger the trowel.

• Strong fluctuations in temperature create tension in the substrate. Catch this tension by expansion joints to be provided right through the screed and the tile adhesive / improved laying mortar. Fill these joints with a compressible material. 
  Always provide an expansion joint between the house and the terrace!

• provide edge joints around the terrace.

• The screed must be at least 5 cm thick. The composition is 250kg cement per m3 coarse sand.
  The screed must dry for at least a month alreadybefore tiles can be placed on it.

• Never make perforations in the moisture seal. This serves to protect the underlying layers against moisture.

​

​PLACEMENT ON CONCRETE

• The main point of attention is that concrete is not permeable to water.Risk of the terrace freezing up during the winter months is big!
  -> To allow the water to drain off, the concrete must be placed in a slope of 1.5% (1.5cm per m).
  -> Further provide a drainage layer by installing a drainage mat. This is a bubble wrap with filter fleece.
       This  drainage mat also provides a decoupling between the concrete and the screed (horizontal tension compensation).

• Place a on the drainage mat reinforced screed with a slope of 1.5%(1.5cm per m). 
  Do not glue the drainage mat.
