FAQ

Yes, they are inevitable. They are also in
materials derived from wood, natural stone
or any ceramic material. The dimension of
16. What are the different finishes of
Silestone®?
Polished (bright and shiny) and Suede (mae).
17. Are there Suede finish for
all colours?
No. Again, the choice of colours for this finish
is strategic and based on trends, best sellers
and availability. For this reason, certain
colours are only available in the Suede finish.
18. Does the Suede finish have the
same level of resistance as the
polished finish?
The Suede finish is even beer than the
polished finish in terms of stain resistance
and fingerprints. It also features easy
maintenance since it is hiding dust.
19. Does Silestone® resist stains? Is it a
porous material?
Silestone® is highly resistant to stains from
coee, wine, olive oil, make-up and many other
everyday products when properly maintained.
The Silestone® coecient of porosity is
practically null and much lower than that of
granite or marble. It is also more stain
resistant than acrylics and laminates.
However, be careful not to leave on liquids,
such as, tea, coee or red wine on the surface
for more than 24 hours. Reason being, if
liquids like these are exposed to the surface
for such a long time this may penetrate the
material, and may require a billable service
call request. Remember that Silestone is
stain resistant, not stain proof.
20. Does Silestone® withstand acids?
Yes. Silestone® is not affected by common
kitchen acids like lemon juice, tomato juice
or vinegar (food acid). Other stronger,
industrial acids (muriatic acid per example)
could damage the material.
21. Are water repellants or gloss enhancers
needed with Silestone® as with other
surfaces?
No. Silestone does not need any water
repellent or gloss enhancer. Cosentino®
recommends avoiding all these products
as they can lead to important care and
maintenance problems and void your
Lifetime warranty.
33. Are seams inevitable? Can the seams
be removed or hidden in any kind of way?
No. The polyester resin yellows and loses
colour with ultraviolet. This is why Silestone®
is a product exclusively indicated for interiors.
There is nothing to fear from large windows
in our kitchens since the sun will not hit our
countertop more than a few hours a day. In
addition, the vast majority of windows now
include double-glazed systems that minimize
the passage of ultraviolet rays. For exterior
projects, use Dekton® surfaces.
31. How do I register the warranty?
Your local fabricator will take care of registering
the warranty since our system requires
information that the end customers don't have
access to. No need for Home Depot customers
to register!
32. Are the samples representative?
Can the tones vary from one slab to
another?
Although they are representative and the
variations that can present are slight due to
our consistent manufacturing process, samples
may not be a perfect replica, especially for
colours with high variation, such as, Calacaa
Gold. Our colours are a combination of pigments
and quartz. Both materials undergo natural
variations of tone and granulometry. The sticker
on the back of the samples warns of this and
we recommend slab viewing to manage
customer's expectation. Samples can be ordered
online at homedepot.ca or signed out at store
level in some areas.
29. What is Silestone® warranty?
Limited lifetime for products sold aer
October 24th 2019, 25 years for products sold
and registered aer January 1, 2015. 15 years
for products sold aer 2000.
30. What does this warranty cover?
It is important to dierentiate the product
warranty from the installation warranty. For
Silestone®, horizontal and vertical applications
installed permanently inside a building. Covered
assumptions shall be those derived from
material manufacturing defects. Never for
improper handling, transportation, processing,
finishing or installation of the product. Neither
will it cover thermal shocks, chemical treatments,
cracks, stains, colour variations from store
sample, the placement of excessive weights,
chipping or damage from the generation of
static electricity. Also, this warranty does
not cover consequential or incidental
damage, loss or expense other than the
product itself, including, but not limited to,
damage to other products or installations,
or additional or supplementary repairs/
modifications on plumbing, electrical, tile,
masonry work or wall surface modifications
that may be necessary to repair or replace
the Silestone® product covered by this warranty.
26. What advice does Cosentino® give
for cleaning and routine maintenance
for this material?
Water and neutral soap, such as Dawn, with
a clean microfiber cloth for daily maintenance.
For dicult stains, refer to the Silestone®
Care and Maintenance Guide or contact
your Cosentino/Fabricator representative.
27. Which products should be avoided?
Strippers, caustic soda or products with a
PH higher than 10 (Easy O) and solvents
with acetone. Any product based on chlorine,
including wipes, acids degreasers with high
mineral charge. Also avoid metal scouring
pads and scouring or abrasive sponges.
Maintain your Silestone® surface as
recommended in the Silestone® Care and
Maintenance Guide.
22. Does Silestone® withstand heat?
Silestone holds up beer than the vast
majority similar application products, such
as, laminate, wood and solid surface. However,
Cosentino® recommends using a trivet
because it is not warranted against thermal
shock.
23. Is Silestone® resistant to impacts?
Silestone® resistance to impact is very high.
It far exceeds that of other products with
similar applications, such as, natural stone
or solid surfaces. That being said, care not
to hit the exposed ends, corners, cutouts
and edge profile especially in the dishwasher
and sink area.
24. Is Silestone® resistant to scratching?
Silestone® is highly scratch resistant. Quartz
is one of the hardest minerals in existence.
The Mohs scale classifies it as the hardest
7 earth mineral behind topaz, corundum and
diamond. Silestone® is therefore more resistant
than the vast majority of natural stones. In
general, it is not micro-scratched like acrylic
products, and is broadly more resistant than
any laminated or stratified product. Despite
this, Cosentino® recommends using a cuing
board and avoiding jagged knives, ceramic
knives, choppers, unfinished dishware and
clay pots directly on the worktop. Also,
scouring pads or abrasive sponges should
be avoided as they can deteriorate the
polished surface.
25. Does Silestone® oer a microbial or
bacteriostatic protection?
Due to its low porosity, Silestone® is considered
an antibacterial surface, which limits the
proliferation of bacteria. However, Silestone®
is not considered an antimicrobial surface as
this would require a special agent to be built in.
28. Does Silestone® resist the ultraviolet
rays?
