Tile adhesive and grout material
When working with Petraluxe tile, only use high-quality tile
adhesives and grouting materials. We recommend Sopro
brand products, for example. The company is one of the
leading specialists in the area of tile technology and
Recommendations for laying large-format tiles
Large-format tiles enable the discerning builder to design a
generous expanse of surface with very few joints.
Important recommendations for laying the large-format tiles
by Petraluxe are listed below.
When installing large-format tiles, always check the building‘s
underlying structural capacity! Only use mortar that
satisfies DIN 12004. Please note that setting times are
Preparing the subfloor
The varying conditions at any given work site should always
be taken into account when laying tile.
· An unheated calcium-sulphate subfloor is ready for laying
tile at < 0.5 CM %
· a heated calcium-sulphate subfloor is ready at < 0.3 CM %
· and a cement subfloor at < 2.0 CM %
When planning the floor, it is important to take into account
the different expansion coefficients of the various subfloors
as exactly as possible. To increase the subfloor’s stability
we recommend using a primer.

longer due to the tile‘s size. This also affects the time
before the tiles may be walked on.
You‘ll find additional important tips for laying tile in
“Large-Format Ceramic Tiles”, a publication issued on May
27, 2010 by Germany‘s building trade association, the
Zentralverband Deutsches Baugewerbe, and attached to
the appendix.
Laying tiles
Since NatureDeluxe tiles are rectified, they can also be laid
without joints. For an easier and problem-free process,
Petraluxe recommends using a 3mm joint when laying large
tiles.
Once the subfloor has been checked for proper evenness
and load-bearing capacity, the tiles can be laid. To guarantee
damage-free construction, it is vital to avoid any cavities
under the tiles.
The adhesive bed should be prepared using the floating
and buttering method utilizing an appropriately sized
notched trowel. A correctly-sized joint, corresponding to
the tile, can be used to relieve stress. Make sure to include
enough expansion joints. If you’re laying tile in a thick
mortar bed, the bed must be least 15 mm in thickness.
Laying floor tiles
1. Vacuum the floor 2. Fasten edge insulating strips along the
base of the wall
It takes just a few steps to lay the tiles on level floors:
first, vacuum the floor to remove all dust. Next, apply edge
insulation strips along the base of the walls. Apply primer
4.1. Apply premixed mortar 4.2. Spread premixed mortar evenly
(watch the drying time)
To level any unevenness, premixed mortar (e.g. Sopro)
should be poured onto the dried, primed surface and
spread evenly with a smoothing trowel and spiked roller.
Once the subfloor has been prepared, put down a contact
layer of a flexible adhesive (e.g. SoproVario- Flex’ XL,
6. Lay down tiles
(optimum joint width: 3 mm)
Lay down the prepared tile into the fresh adhesive bed,
precisely on its final location. Optimum joint width is 3 mm.
3. Apply primer (watch the drying time!)
(e.g. Sopro) with a lambskin roller to the clean, slightly
ground calcium-sulphate subfloor.
5. Apply tile adhesive on floor/wall and tile,
using the floating and buttering method
especially formulated for large-format tiles). Next,
create a ridged bed using a notched trowel. Apply a
contact layer on the back side of the porcelain tile using
a flexible adhesive (e.g. SoproVario- Flex’ XL).
7. Align tiles 8. Apply grout and clean the surface
After grouting the joints and the appropriate curing time,
clean the tiles with a cement haze remover.
