Sikalastic® Rapid Structured Coating RA

Two-component pigmented and filled Polymethylmethacrylate (PMMA) Resin and catalyst

Unopened products have a shelf life of at least 12 months.

Store products sealed in their original airtight container and in a cool, dry and frost-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.

1.60 g/cm³
(Density will vary from colour to colour)

Ambient Temperature -5 °C min. / +40 °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.

Substrate Temperature -10 °C min. / +35 °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 12 minutes

Sikalastic® Rapid Structured Coating RA can be applied either to the hardened Sikalastic® Rapid Cementitious Primer or to the hardened Sikalastic® Rapid levelling Mortar, as required.

Primer is not required on asphalt surfaces.

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. Ideally the roller-applied coating should therefore be re-potted once before stirring again. 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:
Aluminium blade approx. 60cm or smoothing trowel

Surface treatment with a sheepskin roller

Use a smoothing trowel to spread the material evenly and smooth it over, using the particle size as a guide to layer thickness. To achieve the desired finish, go over the area with a sheepskin roller.

Refer to Sikalastic® Rapid Method Statement for more information

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. 10minutes). This can be done with a brush. Do not use the tools again until theCleaner has evaporated fully.

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