To be used as a manually applied thin top coat for external use. 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. PERMURO render is the component of KABE THERM RENO, KABE THERM ELASTO, KABE THERM AVANT* EWI systems based on EPS. The substrate should be primed with PERMURO GT prior to the application of the render.

* If a product of EWI system is used, the manufacturer provides a guarantee only when all KABE THERM RENO or KABE THERM ELASTO or KABE THERM AVANT system components are applied.

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 compounds application. If the acrylic finish coat is applied on new mineral substrates (i.e. cement, concrete render, cement-lime render) – a min. 4-week curing period is required. Prior to using render in KABE THERM RENO, KABE THERM ELASTO and KABE THERM AVANT EWI systems, all coats of EWI systems should be applied in accordance with the requirements for external thermal insulation composite system (ETICS). Acrylic render can be applied on the primed surface only when reinforcing coat is completely dry, i.e. after 3-4 days under normal conditions.
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. To reduce the risk of substrate colour showing through the texture of top coat (especially when using a render of scraped or mixed texture), it is recommended to use a primer of the same colour as the top 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. 0.25 l per 25 kg of the product). Quantity of added water may vary depending on the substrate type, drying conditions and application method.
APPLICATION METHOD: Using a stainless steel trowel, apply a thin, uniformed quantity of the product to the substrate. The thickness of the render should be equal to the grain size. To create texture, rub the surface with a plastic trowel with a circular motions (solid and mixed texture) or with longitudinal motions in vertical or horizontal directions (scraped texture). Render of modelled texture should be applied onto the substrate by using a stainless steel trowel with a thickness of 1÷5 mm and then finish the pattern with a roller, trowel or sponge as needed. A top coat of smooth texture is applied in two stages. At first, distribute the top coat of solid/grained texture as described above, and then (when it is bounded), apply the second coat of modelled texture render. Spread the render of modelled texture in circular motions and thoroughly smoothing the whole surface.
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 can 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.
