Three-component Polymethylmethacrylate (PMMA) Resin, powder and catalyst.

12 months

Store products sealed in their original airtight container and in a cool, dry andfrost-free place.
Direct sunlight on the containers should be avoided, including on site. After removing some of the contents, reseal the containers so they are airtight.
Reference should also be made to the storage recommendations of the material safety datasheet.

1.76 g/cm³

+3 °C min. / +35 °C max.

The relative humidity must be ≤90%

Beware of condensation. Surface temperature during application and cure must be a minimum of 3°C above dew point.
The substrate temperature must not be less than +3°C if a topping is applied to the surface. Reaction problems can occur at lower temperatures.

+3 °C min. / +50 °C max.

The surface to be coated must be dry and ice-free
The surface must be protected from moisture until the coating has hardened

The material in opened containers should be applied immediately
At 20°C, 2% catalyst the pot life is approximately 15 minutes

Note: Times are approximate and will be affected by changing ambient conditions.
Higher temperatures or greater proportions of Sikalastic Rapid Catalyst will reduce reaction times, while lower temperatures and smaller proportions of Catalyst will increase reaction times.
The following table indicates the recommended amount of Sikalastic Rapid Catalyst required to adjust the curing reaction to the temperature.

Return-to-service times are provided as a guide only and may vary as a result of conditions. Newly installed balconies should be protected from exposure to heavy traffic by overlaying with an appropriate protective covering. This is particularly critical where early access is needed by other construction related traffic. Sika Liquid Plastics will not be held responsible for damage to balcony surfaces that results from failures to adequately protect newly laid areas.

Sikalastic®-Rapid Levelling Mortar 4.0kg/m²

Use a twin-paddle stirrer to mix the product
First stir the base resin thoroughly and transfer to a mixing container. Add the Sikalastic® Rapid Levelling Mortar Powder while stirring and continue until a
smooth consistency is achieved (no lumps).
Then add the Sikalastic® Rapid Catalyst while stirring the resin at the slow speed setting and mix for 2 minutes. Make sure that the product on the base and sides of the container is mixed in.
At product temperatures <10°C the product should be stirred for 4 minutes,as the catalyst will take longer to dissolve.

For applying the product:
Coating trowel with triangular teeth (notch pattern 92) or Smoothing trowel

Use a notched or smoothing trowel to apply an even coat of the mixed levelling mortar (approx. 4.0kg/m²).

Refer to Sikalastic® Rapid Method Statement for more information

Preparation for subsequent layers:
Surfacing supplied by others and applied subsequently:
Fully bonded surfacing (e.g.tiles) While the levelling mortar is still liquid, top with a generous amount of Sikalastic Rapid Aggregate
Vacuum off the excess/loose sand after the surface has hardened. The sand topping creates the necessary roughness (key) and absorbency
for the subsequent application of surfacing supplied by others. Only use dry quartz sand (e.g.Sikalastic Rapid Aggregate).

Application as equalising mortar
To equalise layer thicknesses of between 3 mm and 10 mm, add additional amounts of coarse, fire dried quartz sand (1-2 or 2- 3 mm) to
the mixed levelling mortar before adding the Sikalastic Rapid Catalyst (15–20kg sand to 33 kg levelling mortar). Once the catalyst has been
mixed in and dissolved, apply the mortar using a trowel.

If work is interrupted or when it is completed, clean the tools thoroughly with Sikalastic® Rapid Cleaner within the pot life of the material (approx. 10 minutes). This can be done with a brush. Do not use the tools again until the Cleaner has evaporated fully.

Simply immersing the tools in the Cleaner will not prevent the material hardening.
