INSTALLATION PLANNING
The only way to guarantee the long-lasting performance of ceramic
installations is to properly plan the process. We therefore
recommend that national regulations currently in force in each
country be carefully read, for example UNI 11493 in Italy, which
provides all necessary instructions regarding the choice of
materials, correct planning, use and installation, so as to ensure all
quality, performance and durability standards are safely met.
Some of the general precautions that need to be followed are listed
below as an example.
Substrates
Before installation, check that the substrates are clean, free of
loose fragments, properly dried and cured, flat and level, and that
mechanical resistance requirements based on the intended use
have been met.
Worksite conditions
At the time of application, check that worksite temperature,
humidity, light, etc. are adequate.
Materials
Check that all materials used for tiling (ceramic materials, levelling
systems, adhesives, grouts, waterproofing products, etc.) are
suitable for the intended use and have been correctly stored.
Expansion joints
Check that the perimeter, expansion, fractionation and structural
elastic joints have been correctly designed and prepared. Divider
joints are normally needed for 20/25 m
2
sections in interiors, and 9-
15m
2
sections in exteriors. For exteriors, make sure joints are
properly waterproofed and sealed.
Back-buttering
In the case of outdoor installation, swimming pools, large spaces,
high- or heavy-traffic floors, thin slabs, and vibrating substrates,
and where temperature fluctuation is expected, it is necessary to
apply the adhesive both on the substrate and on the back of the
tiles, in order to obtain a full adhesive layer without gaps.
Joints
In any type of ceramic tiling, suitably sized joints must be
developed based on the following parameters:
• Type, format and size tolerance of tiles;
• Thermal expansion coefficients of the tiling materials being used;
• Mechanical properties of installation materials;
• Location and path of joints;
• Mechanical characteristics of the substrate;
• Environment of use and expected operating conditions.
JOINT-FREE INSTALLATION IS NOT PERMITTED.
Any plastic spacers must be removed before grouting.
MIX RATIO
Component A 92.6 parts by weight
Component B 7.4 parts by weight
The two parts are pre-batched in their respective packaging.
MIX PREPARATION
Pour component B (catalyst) onto component A (paste). We
recommend pouring all the catalyst contained in the bag. Mix
preferably with the help of a drill mixer to obtain a smooth, lump-
free mix. Hand mixing is not recommended. The two parts are pre-
batched in their packaging, avoiding , this way, all risk of mixing
errors.
APPLICATION
Apply the product with a notched trowel. The trowel notch size will
depend on the size of the tiles. In any case, the trowel must allow a
backwash of 65-70% in the case of indoor installation, and 100% in
the case of outdoor installation, for floors subject to heavy traffic or
mechanical stress, and for swimming pools.
In the case of single-step waterproofing and installation of ceramic
material or mosaics in shower enclosures or humid indoor
environments, a layer of at least 1 mm of product must be applied
onto the area to be waterproofed. After hardening (about 24
hours), apply the adhesive with a notched trowel to install the
ceramic material.
TILE INSTALLATION
Tiles are laid on the adhesive, applying pressure to ensure contact
with the adhesive, which must be used within a maximum period of
50 minutes after preparation. At normal temperature and humidity
conditions, the product has a working life of approximately 1 hour.
This parameter may be shortened at high temperatures, or
otherwise extended at low temperatures. The tiles must be laid by
making joints of a width suitable for their size. During installation, it
is necessary to work around expansion or splitting joints, if any.
Leave a 5 mm space in between tiles and walls, or any surface
elevation. The ceramic surface must be protected for at least 24
hours from any leaching. Tiled surfaces can be put into operation
after about 7 days.
GROUTING
The grout can be sealed after about 24 hours. For sealing, it is
possible to use cement-based sealants Litochrom 0-2, Litochrom
1-6, Litochrom 3-15, Monomix, ready-to-use polymeric mortar or
Starlike
®
or EpoxyÉlite EVO 2-part epoxy sealants.
WARNINGS
• Do not add lime, cement, water or solvents to the product.
• Apply the product at temperatures between +10°C and +30°C.
• Do not apply the product on damp surfaces or surfaces subject to
rising damp.
• Do not use the product for applications not stated in this technical
sheet.
