SikaLatex® R
Acrylic latex bonding agent/admixture for portland-cement mortar/concrete

PRODUCT DESCRIPTION CHARACTERISTICS / ADVANTAGES

SikaLatex® R is an acrylic-polymer latex. It is not re- ▪ Concrete/Mortar/Grout/etc. containing SikaLatex® R
emulsifiable. It is a general purpose admixture which will exhibits improved adhesion to pre-pared substrates
produce polymer-modified concrete and mortar. Sika ▪ Increased adhesive strength of mortar/concrete when
Latex R is also a bonding grout when mixed with sand used as a bonding grout
and portland cement. ▪ Increased resistance to freeze/thaw durability
▪ Does not produce a vapor barrier
USES
▪ Admixture (replacing water) used in cement based
products to improve adhesion, achieve a denser
surface, and improve overall performance
▪ As a bonding grout (prime coat) when mixed with sand
and portland cement

APPLICATION INSTRUCTIONS SikaLatex® R to seal the surface.

SURFACE PREPARATION
Applying Concrete/Mortar: Remove all deteriorated
concrete, dirt, oil, grease, and all bond-inhibiting
materials from surface. Be sure repair is not less than
1/8 in. (3.2 mm) in depth. Preparation work should be
done by high pressure water blast, scabbler, or other
appropriate mechanical means to obtain an aggregate-
fractured surface with a minimum surface profile of 1/16
in. (1.6 mm). Saturate surface with clean water.
Substrate should be saturated surface dry (SSD) with no
standing water during application.
MIXING
As admixture/mixing solution: With mixer running, add
materials in the following order: SikaLatex® R solution
and then the cement based product. Replace the
amount of water recommended by the product. Do not
dilute with water.
As a bonding grout: With the mixer running, add in the
following order. SikaLatex® R solution, aggregate,
cement. The ratio is 1 part cement, 2 parts sand, and a
sufficient amount of undiluted SikaLatex® R to produce a
creamy paint consistency. Maximum 4 gal./sack of
cement (15L/sack of cement).
As a primer for acrylic coatings: No dilution is required.
Use as is.
APPLICATION METHOD / TOOLS
Admixture: Immediately trowel SikaLatex® R mortar or
concrete mix into areas to be patched. Do not over-
finish. As soon as the application is done, to prevent
damage, cure with damp burlap and/or white
pigmented polyethylene film. Curing should continue for
24 hours. Pre-testing is recommended when adding
SikaLatex® R to a specific mix design to assure the results
required.
Bonding Grout: Brush grout into area to be resurfaced
with stiff-bristled broom or scrub brush. Be sure entire
surface and all edges are coated. Apply topping
immediately over scrub coat before the bonding slurry
dries.
Primer (for acrylic coatings only): Apply undiluted
SikaLatex® R to prepared concrete substrate using
brushes, rollers, soft brooms, or spray. SikaLatex® R
must be tack-free (film formation) prior to coating.
Estimated coverage on a CSP-3 prepared surface is 300
ft2/gal. (7 m2/l) SikaLatex® R primer may be applied up to
24 hours ahead providing the area is kept dry and clean.
Very porous concrete may require a second coat of
