Sikalastic® Rapid Structured Coating RA

Two component, pigmented and filled PMMA-based coating

Sikalastic® Rapid Structured Coating RA offers excellent abrasion-resistance and skid-inhibiting properties, and was developed specifically as heavy-duty surfacing and can be applied to asphalt substrates without a primer. The product is used as a prime surfacer, a topping layer and final course on external surfaces that are subject to heavy pedestrian traffic.

  • Maximum abrasion resistance
  • Easy and fast application
  • Cold applied
  • Fast-curing
  • Solvent-free
  • Variable roughness
  • Weather-resistant (UV-, hydrolysis- and alkali-resistant)

Usage

  • To create heavy duty, skid inhibiting walkways
  • For new construction and refurbishment projects

Product Details

Product Information

Chemical Base

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

Shelf Life

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

Storage Conditions

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.

Density

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

System Structure

Preparation

Prior to priming all substrates must be clean dry and sound free from any oxidisation, mould and any other deleterious materials.

Wearing Layer

Sikalastic® Rapid Structured Coating RA

0.6-0.9 kg/m2
(depending on
desired texture)

Application

Application Information

Ambient Air Temperature

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

Relative Air Humidity

The relative humidity must be ≤90%

Substrate Temperature

Substrate Temperature -10 °C min. / +35 °C max.
 

Dew Point

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 Moisture Content

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

Pot Life

The material in opened containers should be applied immediately
At 20°C, 2% catalyst the pot life is approximately 12 minutes

Application steps

SUBSTRATE PREPARATION

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.

MIXING

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.

APPLICATION

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

CLEANING OF TOOLS

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.
