APPLICATION INFORMATION
Coverage
As mixing solution: for Concrete/Mortar/Grout/etc. use neat, replacing the
amount of water typically recommended
As a bonding grout: estimated coverage based on amount of material
(sand/cement) mixed
APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY / PRE-TREATMENT
Applying Concrete/Mortar: Remove all deteriorated
concrete, dirt, oil, grease, and all bond-inhibiting materi-
als 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 appropri-
ate 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. Repalce 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, ce-
ment. The ratio is 1 part cement, 2 parts sand, and a suf-
ficient amount of undiluted SikaLatex® R to produce a
creamy paint consistency. Maximum 4 gal./sack of ce-
ment (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-fin-
ish. As soon as the applciation is done, to prevent dam-
age, 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 immedi-
ately over scrub coat before the bonding slurry dries.
Primer (for acrylic coatings only): Apply undiluted SikaL-
atex® R to prepared concrete substrate using brushes,
rollers, soft brooms, or spray. SikaLatex® R must be tack-
free (film formation) prior to coating. Estimated cover-
age on a CSP-3 prepared surface is 300 ft
2
/gal. (7 m
2
/l)
SikaLatex® R primer may be applied up to 24 hours
ahead providing the area is kept dry and clean. Very por-
ous concrete may require a second coat of SikaLatex® R
to seal the surface.
LIMITATIONS
Not resistant to UV rays unless painted, covered or
coated.
▪
Will not adhere to polyethylene, Teflon, silicone, oils
and greases, mold release agents and similar materials.
▪
Do not expose to open flame or temperatures above
120 °F (49 °C). Excessive heat can cause shorter shelf
life.
▪
Not intended as a firestop.▪
Do not use where temperatures rise above 240 °F (116
°C).
▪
As with all cement based materials, avoid contact with
aluminum to prevent adverse chemical reaction and
possible product failure. Insulate potential areas of
contact by coating aluminum bars, rails, posts etc.
