Kerapoxy is a two-component, epoxy-resinbased product with silica sand and special
components, with excellent resistance to
acids and excellent cleanability.
This is a product with very low emission of
volatile organic compounds and is classified
Emicode EC1 R Plus by GEV when used for
The following features are obtained when
? Excellent mechanical and chemical
resistance, therefore excellent durability.
? A smooth final surface with low water
absorption, therefore easy to clean; ensures
? Easy workability and finishing.
? Becomes very hard and is highly resistant
to heavy traffic.
? No shrinkage, therefore absence of cracks
? Uniform colours that are resistant to
ultra-violet rays and atmospheric agents.
? Excellent bonding.
? Because of the tessara?s reduced
thickness, Kerapoxy can also be used for
grouting glass mosaics with joints less than
? When grouting ceramic tiled floors and
walls subject to oleic acid attack (e.g. ham
and sausage industries, oil-mills, etc.) and
aromatic hydrocarbon, Kerapoxy IEG can
be used (available in 113 or 130 reference
colour of MAPEI range).
? For flexible expansion joints or joints
subject to movement use an elastic sealant
from the MAPEI line (e.g. Mapesil AC,
Mapesil LM, Mapeflex PU45 FT or
? Kerapoxy does not ensure perfect
adhesion when used for grouting tiles with
wet edges or contaminated with cement,
dust, oil, grease, etc.
? Unglazed klinker tiles should be grouted
with the same colour tone Kerapoxy.
All other colours should be used only with
? Do not use Kerapoxy for grouting
terracotta tiles because they are difficult
? Make preliminary sample tests before
grouting porcelain tiles with a contrasting
colour of Kerapoxy (e.g. black on white).
? Always carry out preliminary tests before
grouting stone or ground porcelain with a
porous or rough surface.
? Do not add water or any solvents to
Kerapoxy to make it more fluid.
? Use the product in temperatures between
+12?C and +30?C.
? The quantities are already in the correct
proportions, therefore mistakes should
not be made. Do not guess the quantities
when mixing the two components. A wrong
catalysis ratio could impair the hardening
? When removing already cured Kerapoxy
from the joints, use a hot air industrial drier.
Remove hardened Kerapoxy from the tiles
with Pulicol 2000.
? When grouting large floor surface areas,
it is recommended to use Kerapoxy P,
available in grey 113 of MAPEI range
(other colours are available upon request
for quantities higher than 300 kg) because
it is very fluid and easy to apply.
Preparing the joints
The joints must be dry, clean, free of dust
and emptied at least 2/3 of the tile thickness.
The excess adhesive or mortar should be
removed while still fresh.
Before grouting, make sure that the
installation mortar or the adhesive has set
and released most of its moisture.
Kerapoxy is not affected by the moisture
on the surface; the joints should not be wet
Preparing the mix
Pour all the hardener (component B), into a
bucket containing component A and mix well
until a smooth paste is obtained. For perfect
mixing and avoiding overheating of the
mixture, which could reduce working time,
a low speed electric stirrer should be used.
Use the paste within 45 minutes from mixing.
Applying the grout
Spread Kerapoxy with the appropriate
MAPEI float, making sure the joints are
completely filled. Use the same float, but
on edge, to remove excess grout.
After grouting with Kerapoxy, floors and
walls should be cleaned immediately, before
the product dries.
Wet the surface thoroughly and emulsify with
an abrasive pad for cleaning joints (such as
Scotch-Brite? or MAPEI tile-joint cleaning
kit), making sure not to wash-out the joints.
When cleaning walls, the cleaning pad should
be fully soaked with water. The excess liquid
can be removed with a hard cellulose sponge
(e.g. MAPEI sponge), and should be replaced
when too full of resin. Use the same type of
sponge for the final tooling of the grout.
It is very important that once the finishing
process has ended, no traces of Kerapoxy
