ARMASIL T AKORD – Silicone render for spray application
It is used for spray (machine) application of thin coat renders outside buildings including KABE THERM RENO* EWI system based on EPS, and KABE THERM MW* EWI system based on mineral wool. It is especially recommended for large surface areas as well as for the substrates of curved, irregular shapes. It features high coverage capability and quick application. It is used on both mineral substrates (e.g.: concrete, cement render and cement-lime render) and on synthetic substrates covered with well set polymer-based coatings. The substrate should be primed with ARMASIL GT before applying the render.
* Using the material as a part of the insulation system, the manufacturer provides a guarantee only if all components of the KABE THERM RENO or KABE THERM MW systems are used.

• Top resistance to adverse atmospheric conditions
• High dirt resistance
• Highly efficient
• Very high adhesion to the substrate
• Additional anti-fungal and algae protection
• Quick and easy application
SUBSTRATE PREPARATION: Apply to a sound/stable and clean substrate (without cracks and delaminations), degreased, even and dry, and biological or chemical efflorescence free. In case of algae/fungi growth, the substrate should be cleaned mechanically and then wash with water and disinfect with ALGIZID. Old and/or dirty substrates should be washed off and degreased with water and CLEANFORCE cleaning agent. Any loose layers not bound to the substrate (i.e. loose render or flaked coatings) should be removed. If there is any large unevenness of the substrate (from 5 to 15 mm), use levelling compound and then apply the whole surface with KOMBI base coat. Minor unevenness (up to 5 mm) can be levelled out at once and smoothened with KOMBI base coat mortar. Absorbent substrates should be primed with BUDOGRUNT ZG before levelling compound and/or finish levelling and smoothing compounds application. Use the above products according to their technical data sheets. Fresh concrete substrates, cement renders and cement-lime renders may be rendered only after a curing period of at least 2 weeks. All coats of EWI system should be applied in accordance with the requirements for external thermal insulation composite system (ETICS).
PRIMING: The substrate should be primed with ARMASIL GT before applying the render. Primer should be dry before applying a finish coat, curing period lasts about 24 hours. It is recommended to use a primer that is of the same colour as the finish coat.
PRODUCT PREPARATION: The packaging contains a ready-to-use product. If stored for a long time and before application, the product should be thoroughly mixed with a low-speed mixer fitted with a basket stirrer until a smooth,
homogenous consistency is obtained. Further mixing is not recommended as it may result in excessive aeration of the product. If required, add a small amount of clean water (max. 0.1 l per 20 kg of the product). Quantity of added water may vary for different substrate types, drying conditions and application method.
APPLICATION METHOD: Render should be applied onto the substrate by using a pneumatic spraying device at a working pressure of 3÷4 atmospheres and a nozzle diameter of 5÷6 mm. While spraying, the gun should be held perpendicularly to the substrate at a distance of 0.4-0.6 m.
DRYING: Typical drying time ca. 24 h (20°C, 55% RH). Note: Drying time may be longer, up to several days due to low temperatures and high relative humidity. To assist the drying of the finish coat, the surface should be protected against precipitation and condensation.
USEFUL HINTS: The final effect may depend on the substrate type. For non-uniform substrates, it is recommended to apply at first the whole surface with KOMBI base coat. To avoid colour differences, a single batch product should be applied to entire facade or element. ‘Wet on wet’ method should be used. All tools should be cleaned with water after work is completed. To be applied on dry days at temperatures between 5-25°C. Avoid applying in direct sunlight or during strong winds. To protect the fresh coat against inclement weather conditions, scaffolding should be covered with some protective netting or tarpaulin.
