SikaLatex®-200 SBR

USES
SikaLatex-200 SBR  is used as bonding agent and
site-mix mortar admixture for the following applications:
▪ Thin layer patching mortars
▪ Renders
▪ Floor screeds
▪ Concrete repair mortars
▪ Abrasion resistant linings
▪ Tile fixing mortars
▪ Masonry mortars
▪ Bonding slurry for fresh to old concrete

CHARACTERISTICS / ADVANTAGES
SikaLatex-200 SBR  is simply added to the mixing
water to improve the following properties:
▪ adhesion
▪ shrinkage
▪ water resistance
▪ abrasion resistance
▪ chemical resistance
SikaLatex-200 SBR  is non-corrosive, ready to use
and does not re-emulsify, even under highly alkaline
conditions.
APPROVALS / STANDARDS
SikaLatex-200 SBR  is certified according “Low
Emitting Materials as per Al Sa’fat – Dubai Green Building Evaluation System” by Dubai Central Laboratory
(DCL) certificate No. CL17020432

MIXING
BONDING SLURRY
SikaLatex-200 SBR : Water = 1 : 1
Mix together with fresh cement and fine sand to a homogeneous brushable slurry consistency. The resulting
bonding slurry should be brushed well onto the prepared surface.
MORTARS AND RENDERS
Mixing can be done in any suitable concrete mixer,
such as a pan mixer. First add the cement and aggregate into the mixer and mix to a uniform consistency.
Then add the required quantity of diluted SikaLatex-
200 SBR  and mix slowly for at least 2 minutes. Apply by steel trowel and finish with a wooden float.
DISPENSING
SikaLatex-200 SBR  is generally added to the clean
mixing water within the range 1 : 1 to 1 : 2. For all applications, apart from sprayed on renders, a bonding
slurry should be applied. Subsequent mortar application must be carried out whilst the bonding coat is still
wet.

APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY
Concrete surfaces should be clean, sound, rough and
free from oil, grease, cement laitance and all loosely
adhering particles. The surface should be in a saturated surface dry condition.
AGGREGATE GRADING
Aggregates should be well graded and thoroughly
washed. Sand particle sizes should correspond to the
thickness of mortar to be applied and required surface
finish.
Mortar thickness Aggregate size
< 2 mm 0 – 0.5 mm
2 – 5 mm 0 – 1.0 mm
5 – 15 mm 0 – 3.0 mm
