PROJECT APPLICATION
Keracolor GG (CG2 WA, EC1 R Plus) is a pre-blended, highperformance
polymer-modified cementitious mortar for
grouting joints 4 mm to 15 mm wide.
It is an improved (2) cementitious (C) grout (G) for joints of
class CG2 complying with standard EN 13888. It is ideal for
grouting interior and exterior floors and walls finished with all
types of ceramic tiles (single fired, double fired, klinker, porcelain
tiles, etc), terracotta, facebrick and stone material (natural stone,
marble, granite, agglomerates, etc).
Keracolor GG is a mixture of cement, graded aggregates,
synthetic resins, special additives and pigments. The following
features are obtained when mixed with the right water ratio and
used correctly - good compressive and flexural strength, good
resistance to freeze/thaw cycles, good durability, good abrasion
resistance, low shrinkage, good resistance to acids with pH > 3.
It can contribute up to three points towards obtaining LEED
(Leadership in Energy and Environmental Design) certification.
Keracolor SF (CG2 WA, EC1 R Plus) is a fine-grained, highperformance
white cementitious mortar for grouting joints up
to 4 mm wide.
Keracrete+Keracrete Powder (CE EN 12004, C2T, EC1 R Plus)
is a two-component adhesive system made of a ready-to-use
mixture of sand and cement and a latex. This mixture forms a
high-performance adhesive with no vertical slip and is suitable
for ceramic tiles, glass mosaic and stone material.
Keraflex (CE EN 12004, C2TE, EC1 R Plus) is a high-performance
cementitious adhesive with no vertical slip and extended open
time for ceramic and stone tiles.
Keraflex Maxi (CE EN 12004, C2TE S1) is a high performance
deformable cementitious adhesive with no vertical slip and
extended open time for ceramic tiles, and is particularly
recommended for laying large porcelain and natural stone
tiles. The product has been superseded on several markets by
Keraflex Maxi S1.
Keraflex Maxi S1 is a deformable (S1), improved (2) slip
resistant (T) cementitious adhesive (C) with extended open
time (E) of class C2TE S1 according to EN 12004 standard.
It is particularly suitable for interior and exterior bonding, up
to 15 mm thick, on floors, of ceramic tiles of every type and
size on uneven substrates and renders, and of stone materials,
provided that they are not sensitive to moisture. It is also used
for the spot bonding of insulating materials in interiors etc. Its
low dust technology ensures that the amount of dust emitted
while mixing is drastically reduced compared with standard
cementitious Mapei adhesives, making the work area more
comfortable and healthy for floor layers.
It features low viscosity and is easily workable. It is highly
thixotropic and can be applied on a vertical surface without
sagging or letting even heavy and large tiles slip. It ensures good
adherence to all materials normally used in building. It has a
particularly extended open and adjustability time.
It can contribute up to three points towards obtaining LEED
(Leadership in Energy and Environmental Design) certification.
Keranet is an acid-based cleaning solution for ceramic tiles.
Kerapoxy (CE EN 12004, R2T, RG) is a two-component, highperformance,
anti-acid epoxy mortar and adhesive with no vertical
slip for laying and grouting ceramic tiles and stone material.
Mapesil AC (F-25-LM) is a pure, anti-mould, acetic silicone
sealant for movements up to 25%.
Planicrete SP is a synthetic latex rubber that improves adhesion
and strength of cementitious mortar. This product was specially
developed and is distributed in Far East markets by Mapei Far East.
Pulicol is a solvent gel that was used for removing adhesive and
paint residuals from the laid surfaces. The product has been
superseded in several markets by Pulicol 2000.
