Sikalastic® Rapid Clear Sealer

Two-component Polymethylmethacrylate (PMMA) Resin 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.

Please note: the above rates are for smooth substrates only.

-5 °C min. / +30 °C max.

The relative humidity must be ≤90%

+3 °C min. / +40 °C max.

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 tha +3ºC if a topping is applied to the surface.  Reaction problems can occur at lower temperatures.

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.

Apply the finish to the topped self-levelling mortar. The area must be hard (ready to be overcoated) and any loose topping must have been vacuumed off. Sikalastic® Rapid Clear Sealer is used as a durable finish on coloured sand toppings. However, it is not suitable as a receiver for toppings. It is not recommended for sealing surfaces that are both smooth and light in colour.

Use a twin-paddle stirrer to mix the product First stir the tub contents thoroughly.
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:
Finishing roller (sheepskin roller, minimal shedding)
Rubber blade, hard (for applying finish to topped surfaces

Use the finish roller to apply an even layer of the mixed material (approx. 0.6kg/m2). Avoid fluctuating layer thicknesses.

Finish for topped surfaces:
Use a hard rubber blade to apply a first coat of finish and smooth over with a finish roller if required (depending on particle size of topping approx. 0.60 to 0.80 kg/m2).

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.
