RASOKOLL is a high-performance dual-purpose adhesive and render designed for thermal insulation systems. Its pre-mixed formulation of cement, sand, synthetic fibres and advanced additives provides strong adhesion, flexibility, and durability, making it suitable for both bonding insulation boards and acting as a protective render. Available in white or grey, RASOKOLL meets EN 1504-3 standards, ensuring reliable performance in thermal insulation applications.
All surfaces should be clean and free from dust, debris and surface contaminants like grease and oil. Apply a coat of either RAPRIMER or RABINDER based on the substrate to aid in adhesion and ensure proper curing time.
RASOKOLL can be mixed by hand or mechanically using a paddle mixer in a clean bucket with 6 to 7 liters of clean water per 25kg bag. Allow the mixture to stand for 5 minutes, then mix again before application. Always wear eye protection and a dust mask during mixing.
As an adhesive, apply RASOKOLL with a notched trowel at a rate of 4-5 kg/m², ensuring full coverage for proper adhesion. As a render, apply RASOKOLL with a rendering float at a thickness of 3-4 mm, then embed a fiber mesh into the fresh coat for reinforcement. Once the first coat has cured, apply a second 3-4 mm coat as a finishing layer to achieve a smooth and durable surface.
