• Grouting of ceramic and porcelain tiles, mosaics and natural
stones installed on metal surfaces for the construction of
prefabricated bathrooms;
• Grouting of ceramic tiles, thin reinforced porcelain slabs,
mosaics, natural stones or resin agglomerates installed on heated
floors;
• Grouting of glass or ceramic mosaic joints installed on structures
and shapes made of extruded polystyrene panels used in Turkish
baths, hammams and wellness centres;
• Grouting of ceramic tiles, porcelain tiles and thin slabs, including
large slabs with or without reinforced back, installed on external
façades;
• Also recommended for grouting swimming pools or tanks
containing salt or thermal water.
Product suitable for direct contact with food substances under the
following EC legislation: Regulation 1935/2004/EC, Regulation
(EU) 2018/213, Regulation 1985/2005/EC, Directive 2002/72/EC
and subsequent amendments and modifications and under the
following Italian legislation: Ministerial Decree 21/03/1973 and
subsequent amendments and modifications, Presidential Decree
777/82 and subsequent amendments and modifications.
A copy of the certificate may be requested from the Litokol
technical department.
The product can, therefore, be used for grouting ceramic tiles in
environments with direct contact with food, e.g. worktops for
handling meat, dairy products or flour, tanks for breeding fish,
kitchen counter tops in restaurants, fried-food stalls, bakeries, etc.
Preliminary checks and joint preparation
Check that the adhesive or mortar used for bonding the tiles is
completely hardened and dry. The joints must be clean, dust free
and unfilled for at least 2/3 of the tile thickness.
Any traces of excess adhesive or mortar between the joints must
be removed.
Mixing ratios
Component A: 93.7 parts by weight
Component B: 6.3 parts by weight
The two components are pre-measured in their respective
packaging
Preparation of the mix
Cut off a corner of the plastic bag containing the catalyst
(component B), placed in the bucket, and pour it onto component A
(paste). The entire contents of the bag should be emptied out by
rolling it up and gradually pressing the bag from the sealed side
towards the side that has been cut.
Mix using an electric drill fitted with a mixing paddle until a uniform,
lump-free mix is obtained.
Scrape the sides and the bottom of the container, using a steel
spatula, to make sure that all the paste is catalysed.
Hand mixing is not recommended.
The two components are pre-measured in their packaging, thus
preventing the risk of mixing errors.
The paste is workable for approximately 1 hour at a temperature
about +23°C.
Finishes
If the Spotlight, Gold, Galaxy and Night Vision finishes are used,
add the product as the third component after mixing the catalyst
(component B). Make sure you pour it in slowly as these additives
are very volatile and use a mixing paddle at a low speed to avoid
the dispersion of them.
Metallic Collection
To obtain the Platinum, Shining Gold, Bronze, Copper and Rusty
metallic finishes, the respective additives must only be mixed with
Starlike
®
EVO 113 Neutro. Add the product as the third
component after mixing in the catalyst (component B). Make sure
you pour it in slowly as these additives are very volatile and use a
mixing paddle at a low speed to avoid dispersion of the product.
Grouting the tiled surface
Fill the paste obtained into the joints using the special green grout
rubber float (art. 946GR).
For large surfaces, an electric single-brush floor maintenance
machine equipped with an abrasion-resistant rubber brusher can
be used.
Remove the excess product using the rubber float.
The product’s pot life and hardening time is strongly dependent on
the ambient temperature.
The optimum application temperature is between +18 and +23°C.
Under these conditions, the product is soft, easily workable and
with a pot life of approximately 1 hour. It is set to light foot traffic
after 24 hours. The grout is ready for use and resistant to
chemicals after 5 days at a temperature of +23°C.
The hardening time is lengthened by low temperatures and
shortened by high temperatures.
At a temperature of +15°C, it takes three days before the surface
is set to light foot traffic and ten days to be ready for use.
At temperatures between +8 and +10°C, the product is very dense
and difficult to apply. The hardening time is also lengthened
considerably.
Do not add water or solvents to improve workability. In hot
weather, it is advisable to apply the product to the floor as quickly
as possible so as not to shorten the pot life even further due to the
heat of reaction in the container.
CLEANING AND FINISHING
The grouting must be cleaned and finished while the product is still
fresh and, in any case, in the shortest possible time, taking care
not to remove the grout from the joints or leave stains on the
surface of the tiles.
Cleaning and finishing can be performed either manually or using
an electric single-brush machine equipped with a felt disc.
Manual method
First sprinkle clean water over the grouted surface.
If necessary, perform initial cleaning using a float fitted with a
moistened white felt pad (art. 109GBNC). Make circular
movements in both clockwise and anticlockwise directions in order
to seal the sides of the tiles perfectly and to remove excess grout
from the surface of the tiles.
Now perform a second pass with a Sweepex sponge (art.
128G0001) in order to obtain a smooth, closed surface and to
remove the product completely from the surface of the tiles, without
removing it from the joints, as well as to dry off the excess water.
To facilitate the cleaning operation, we recommend using two
buckets full of water, one for rinsing the felt pad and sponge, as
well as to collect any dirty water, and the other filled with clean
water for the final surface cleaning.
Replace the felt pad and sponge when they become impregnated
with resin and can no longer be cleaned.
Any stains or transparent product residue can be removed from the
surface of the tiles after about 24 hours or after the joint has
hardened (depending on the temperature), using the special
Litonet EVO (floors) and Litonet Gel EVO (walls) cleaning
products.
