NOVALIT T AKORD – Polysilicate render for spray application
It is used for spray (machine) application of thin-coat renders outside buildings, including in KABE THERM RENO* EPS-based EWI system and KABE THERM MW* EWI system based on mineral wool. It is especially recommended for use on large surface areas, as well as on substrates with curved, irregular shapes. It ensures high coverage and quick application. Intended for use on mineral substrates (e.g., concrete, cement render, cement-lime render) and on substrates
covered with a well-bonded plastic-based paint coating. The substrate should be primed with NOVALIT GT.

• Mineral nature
• Low-alkaline (pH 8-9.5)
• Resistant to adverse weather conditions
• Highly effi cient
• Very good adhesion to substrate
• Anti-fungal and algae protection (reduces the growth of algae and fungi)
• Quick and easy application
SUBSTRATE PREPARATION: Substrate should be sound/stable (without scratches and cracks), degreased, even and dry, as well as free of biological contamination and chemical effl orescence. In case of algae/fungi growth, the substrate should be cleaned mechanically and then washed with water and disinfected with ALGIZID. Old and/or dirty substrates should be washed and degreased with water and CLEANFORCE cleaning agent. Any loose layers, not bound to the substrate (e.g., loose render or fl aked coatings), should be removed. For particularly uneven substrates (from 5 mm to 15 mm), fi rst use levelling compounds, and then level out the wall surface with KOMBI adhesive/base coat. Minor unevenness (up to 5 mm) can be levelled out and smoothed straight away with KOMBI adhesive/base coat. An absorbent substrate should be primed with BUDOGRUNT ZG before applying levelling compounds or base coats. Use the above levelling compounds and/or base coats according to their technical data sheets. Fresh concrete substrates, cement and cement-lime renders can only be plastered after min. 2-week curing period. The base coats of the EWI system should be performed in accordance with the technology of the External Thermal Insulation Composite Systems for buildings − ETICS.
PRIMING: The substrate should be primed with NOVALIT GT before applying the render. The curing period of the product applied to the substrate before applying the render is about 24 hours. We recommend using a preparation tinted to match the colour of the render.
PRODUCT PREPARATION: The packaging contains a ready-to-use product. If stored for a long time and directly before application, the product should be thoroughly mixed (with a low-speed mixer fi tted with a basket stirrer), until a smooth, homogeneous 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 drinking water (max. 0.1 l per 20 kg of render compound) to thin the product. Quantity of added water may vary depending on the substrate type, drying conditions and application method.
APPLICATION: The render compound should be applied onto the substrate by using a pneumatic spraying device at a working pressure of 3-4 atmospheres and with 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: TTypical setting (hardening) time of the render applied onto a substrate is approx. 24 hours (at +20°C, 55% RH). Note: Drying time may be longer, up to several days, due to low temperatures and high relative humidity. The newly applied render should be protected against precipitation and condensation until it is fully hardened.
USEFUL HINTS: The fi nal eff ect may depend on the substrate type. Therefore, for heterogeneous substrates, it is recommended to fi rst smooth out the entire surface with KOMBI adhesive/base coat. In order to avoid colour diff erences, it is necessary to create a surface constituting a separate architectural whole in one work cycle with material from the same production batch, using the “wet on wet” method. Tools should be cleaned with water immediately after work is completed. The render should be applied and dried on dry days at air temperatures from +5°C to +25°C. Avoid applying in direct sunlight or during strong winds. In order to protect the undried render against severe weather conditions, it is recommended to use appropriate protective meshes or tarpaulins on scaff olds.
