Instructions for Use

Surface Preparation Concrete surfaces should be clean, sound and free from oil grease, cement

laitance and all loosely adhering particles.

 Absorbent surfaces should be saturated thoroughly but no ponding.

Materials  Aggregates should be well graded and thoroughly washed. Sand particle

sizes should correspond to the thickness of mortar to be applied and

required surface nish.

Up to 2 mm thick 0 - 0.5 mm

2 - 5 mm 0 - 1.0 mm

5 - 15 mm 0 - 3.0 mm

over 15 mm 0 - 6.0 mm

Dilution Rates SikaLatex® is generally added to the clean mixing water within the range

1:1 - 1:4. For all applications apart from sprayed on renders a bonding

coat of Sika-Latex-water 1:1 mixed with fresh cement should be brushed

into the prepared surface.

Subsequently mortar application must be carried out whilst the bonding

coat is still wet.

Use and Application 1. Bonding agent for rendering/ Bonding between old and new concrete

Mixing ratio:  1 ltr Latex + 1 ltr water + 4 kg cement = slurry consistency.

  The above slurry covers approx. 4 m2

Application :  Add cement to the Latex-water premix and mix until an

  even,creamy consistency is achieved. Apply the Latex

  slurry onto the prewetted substrate in 1-2 mm thickness

  and place new concrete or mortar render immediately

  (wet-on-wet application).

2. Repair Mortar 

Solution :  SikaLatex® : Water =1:1 (by volume)

  (for coat under 10 mm.)

  SikaLatex® : Water =1:2 (by volume)

  (for coat above 10 mm.)

Dry mix :  Cement : Sand vary from 1:1 to 1:3 (by volume)Granular size : Fine or coarse sand depend on layer thickness

Consumption : 0.7 - 2.3 kg/m2 per cm thickness

3. Floor Screeds, Intermediate coat for water resistant

Solution :  SikaLatex® : Water =1:1 to 1:3 (by volume)

  depend on wearing resistance requirement

Dry mix :  Cement : Sand =1:2 to 1:3 (by volume)

Granular size : Coarse sand (0-max.6 mm.) according coat thickness

Consumption : 0.4-1.9 kg/m2 per cm thickness

Note :  For other application ie. other ratio of solution and Dry mix

  consumption of SikaLatex® can be drawn from the table given.

Important

Recommendation

1. Never use SikaLatex® and water as a bonding coat without adding

cement (and ne sand).

2. Proper curing method is needed

3. Always prewet the absorbent substrate but no ponding

4. Multi-lay work always wet on wet

Cleaning Clean all tools and equipment with clean water immediately after use.
