BASIS OF PRODUCT DATA

All technical data stated in this Product Data Sheet are based on laboratory tests. Actual measured data may vary due to circumstances beyond our control.

USES

• Never use pure SikaLatex®-200 SBR PK water mix directly onto the substrate as bonding bridge, always add cement and sand to the mix.
• The standard rules of good practice for production and placing of bonding bridge, repair and adhesive mortars must be observed when using SikaLatex®- 200 SBR PK . Refer to relevant standards.
• Fresh applied mortar must be cured properly especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® WB product as a curing agent or apply curing by polyethylene sheet and wet hessian.
• Higher dosages can be used depending on the mix design, raw materials, climatic conditions and mortar requirements.
• Trial mixes must be performed to establish the exact dosage rate required.
• We recommend to perform trial mixes to establish the required performance when combining SikaLatex®-200 SBR PK with other products.

ECOLOGY HEALTH AND SAFETY

For information and advice on the safe handling, storage and disposal of chemical products, users shall refer to the most recent Safety Data Sheet (SDS) containing physical, ecological, toxicological and other safety-related data.

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 > 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 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 PK and mix slowly for at least 2 minutes. Apply by steel trowel and finish with a wooden float.

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.
