Safety Notice

Before using RASOKOLL it is recommended to consult the product safety data sheet available on request

Surface Preparation

All surfaces should be completely sound and clean, dry and dust free. Any surface contaminants like grease, oil and efflorescence must be removed in order to promote adhesion.

 

Application

RASOKOLL should be mixed with a mechanical paddle mixer to achieve a smooth and lump free consistency. Mix in a clean bucket using approximately 6-7 litres of clean water per 25Kg bag. Allow the mixture to stand for 5 minutes before application. As an adhesive apply RASOKOLL with a notched trowel at a rate of 4-5 Kg/m² and anchor boards with insulation fixings where necessary. As a render apply a base coat of RASOKOLL with a metal or stainless steel trowel to a depth of 3-4 mm then a fibre reinforcing mesh over the render, leave for 12 hours. Apply a second coat of RASOKOLL to a depth of 3-4 mm as a finishing coat.

 

Recommendations

Do not apply RASOKOLL:

  • When temperatures are below +5°C and over +35°C
  • When the substrate is excessively wet or in very humid conditions
