SikaLatex®-200 SBR PK

Water-Resistant Bonding Agent and Mortar Admixture

SikaLatex®-200 SBR PK is a acrylic dispersion that is used as admixture for cementitious bonding bridges and high-quality site-mix mortars.
Suitable for use in hot and tropical climatic conditions.

SikaLatex®-200 SBR PK is simply added to the mixing water to improve the following properties:
  • adhesion
  • shrinkage
  • water resistance
  • abrasion resistance
  • chemical resistance
SikaLatex®-200 SBR PK is non-corrosive, ready to use and does not re-emulsify, even under highly alkaline conditions.

Application

Application Information

DISPENSING

SikaLatex®-200 SBR PK 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 steps

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

> 15 mm     0 - 7.0 mm

 

MIXING

BONDING SLURRY
SikaLatex®-200 SBR PK: 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 pre- pared 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 PK and mix slowly for at least 2 minutes. Apply by steel trowel and finish with a wooden float.
