It is used for spray (mechanical) application of thin renders coats outside buildings including o KABE THERM RENO EWI system, based on EPS (excluding the grain size of 1.0 mm). 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 and synthetic 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 PERMURO GT before applying the render.

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. Absorbent substrates should be primed with BUDOGRUNT ZG before levelling  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 4 weeks. All EWI system coats should be applied in accordance with external thermal insulation composite system (ETICS) .

PRIMING: The substrate should be primed with PERMURO 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 depending on the substrate type, 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 4-6 mm. While spraying, the gun should be held perpendicularly to the substrate at a distance of 0.5-0.6 m.

DRYING: Typical drying time ca. 6 h (20°C, 55% RH). Total hardening of the top coat takes ca. 48 hours. Note: Drying time may be longer, even up to a few 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 used on a single application / architectural 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.
