DESCRIPTION
Part A consists of a mixture of epoxy resin, inert substances based
on glass beads with a fine particle size and rheological components
of organic origin. Part B consists of a mixture of amine-based
hardeners. The main features of the product are:
●
Translucent colour that allows light filtration.
●
Smooth finish thanks to the fine particle size of the inert
substances.
●
Extremely easy application and cleaning.
●
High mechanical strength.
●
Water proof.
●
Total absence of cracks or crazing after hardening.
●
Excellent chemical resistance.
●
Product suitable for direct contact with food under Italian

FIELDS OF APPLICATION
Starlike
®
Crystal’s special translucent colouring allows the product
applied in the joints to “absorb” the colour of the transparent glass
tiles and then adapt according to the colour. The best results are
obtained if the mosaic is applied to transparent supports such as
glass and Plexiglas, possibly backlit by a light source.
In this case, the mosaics must be glued using a suitable transparent
adhesive in cartridge form. In the case of traditional supports such
as cement plasters or plaster of Paris, panelling etc. the mosaics
must be bonded with Litoplus K55 white adhesive (class C2TE
cement adhesive) or Litoelastic (two-component reactive adhesive
class R2T) depending on the type of support. Thanks to this feature,
with Starlike
®
Crystal it is possible to achieve glass mosaic surfaces
with effects of considerable value and visual impact such as:
● Creating backlit interior walls.
● Backlit coatings of bars or public places.
● Floors and walls in bathrooms, kitchens, showers etc.
● Creating furnishing surfaces such as columns, tables etc.
Another possibility is using Starlike
®
Crystal for grouting artistic, i.e.
compositions made up of mosaic tiles which, when suitably shaped
and mixed, reproduce exclusive images rich in nuances and
shadows. If the grouting of these images is done with traditional
coloured sealants, the appearance of the figure represented is
compromised, because the coloured grout creates a discontinuity
between the mosaic tiles.
Conversely, using Starlike
®
Crystal, thanks to its semi-transparency,
retains the original nuances of the composition, creating “neutral”,
colourless grouting that does not interfere with the image.
PRELIMINARY CHECKS AND PREPARATION OF JOINTS
Make sure that the adhesive used for bonding the mosaic is
completely dry and hardened. The joints must be completely dry,
clean, free of dust and empty for the entire thickness of the mosaic
in order to ensure the translucent effect of the product. For bonding,
it is advisable to use a spatula with small 2 mm triangular teeth (art.
112/D-V2).
MIXING RATIO
Component A: 100 parts in weight
Component B: 8.3 parts in weight
The two components are pre-dosed in their respective packs.
PREPARING THE MIXTURE
Cut one corner of the sachet containing the catalyst (component B)
located inside the bucket and pour it onto component A (paste). It is
advisable to pour out the entire contents of the catalyst, rolling and
squeezing the sachet progressively from the sealed side towards
the cut side.
Mix with the electric drill fitted with a paddle, from the bottom
upwards at a low number of revs until an even lump-free mixture is
obtained.
Scrape the sides and bottom of the bucket with a spatula or trowel
to ensure no non-catalysed product remains. It is not advisable to
do the mixing by hand.
The packs of the components are pre-dosed, and therefore make
any error in mixing impossible. The resulting mixture remains
workable for about 1 hour at a temperature of about +23°C.
GROUTING THE MOSAIC SURFACE
Apply the mixture obtained into the joints, using the special green
spatula (art. 946/GR). In the case of wall application, it is
recommended that the sealant is applied in complete vertical strips
before cleaning.
Remove any excess product using the same rubber spatula. The
material must be introduced in the joints before cleaning with water
so as to prevent the formation of white crystals on the surface.
The workability and hardening time of the product is greatly
influenced by the environmental temperature.
The optimum temperature for application is between +18 and
+23°C.
