NOVALIT F – Polysilicate facade paint
Mineral topcoat paint based on specially modifi ed potassium water glass intended for paint coatings on the external façade of buildings, including in EPS-based KABE THERM RENO, KABE THERM EPS, KABE THERM AVANT EWI systems and in KABE THERM MW, KABE THERM IN MW and KABE THERM SG EWI systems based on mineral wool. It is especially recommended for primary and renovation painting of mineral substrates (such as traditional lime renders, cement-lime renders and cement renders, as well as thin-coat mineral renders, silicate renders, polysilicate renders) and for the renovation painting of substrates with plastic-based paint coatings when mineral paint coating is
required. The polysilicate paint shows a signifi cantly reduced alkalinity (at the level of acrylic products), thanks to which the impact of weather conditions on the quality of created paint coating has been signifi cantly reduced. Absorbent mineral substrates should be primed with NOVALIT GF before applying the paint.

• Mineral nature
• Low-alkaline (pH 8-9.5)
• Resistance to adverse weather conditions
• Increased resistance to changes of weather conditions during application and setting
• Anti-fungal and algae protection (reduces the growth of algae and fungi)
• Increased resistance to soiling
• Micro-porous texture, which assures high vapour permeability
• Low surface absorption
• For use on both mineral substrates and plastic-based renders/plasters
SUBSTRATE PREPARATION: Substrate should be sound/stable (without scratches and cracks), degreased, clean and dry, and 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. Any loose layers, not bound to the substrate (e.g., loose render or fl aked coatings), should be removed. Old and/or dirty substrates should be washed and degreased with water and CLEANFORCE cleaning agent. For particularly uneven substrates, first use levelling compounds, and then smooth out the surface with KOMBI FINISZ levelling and smoothing compound. Small unevenness can be smoothed right away with KOMBI FINISZ levelling and smoothing compound. An absorbent substrate should be primed with an adequate product before applying base coats and/or levelling compounds. If the paint is applied on new mineral substrates (e.g., concrete, lime render, cement render, cement-lime render) – a minimum 2-week curing period is required. Before using the paint in the KABE THERM AKORD, KABE THERM SM and KABE THERM SM RENO, KABE THERM AVANT and KABE THERM MW EWI system, all layers of the system should be made in accordance with the technology for external thermal insulation composite system (ETICS). Polysilicate paint can be applied to thin-coat render only after min. 7 days of curing (at +20°C and 65% RH)
PRIMING: A mineral substrate should be primed with NOVALIT GF before applying the paint. The curing period of the product applied to the substrate before applying the paint is about 12 hours. Note: Substrates with low wettability (such as plastic-based renders or dispersion paint coatings) should not be primed and should be only washed with water and the CLEANFORCE product.
PAINT PREPARATION: The packaging contains a ready-to-use product. If necessary, add a small amount of water (by adding to the first painting max. 10% of volume and to the second one max. 5% of water). Quantity of added water may vary depending on the substrate type, drying conditions and application method.
APPLICATION: The paint should be applied on the substrate in two layers with a brush, roller or by spraying (including also “airless” method). The second paint layer should be applied only after the first one dries completely, i.e. after min.24 hours. Use mechanical spraying only in windless weather. It is recommended to use a special paint roller for façade paints made of woven polyamide with a bristle length of min. 18 mm.
DRYING: Typical setting time for one layer of paint applied onto a substrate is approx. 3 hours (at air temperature +20°C, 55% RH). Complete setting (hardening) of paint coating takes place after min. 24 hours. Note: At low temperatures and high air humidity, the paint drying time will be longer. Protect the fresh paint coating against precipitation and condensation until it dries completely.
USEFUL HINTS: In order to avoid colour differences, it is necessary to create a surface constituting a separate architectural whole in one work cycle with material from the same production batch. Paint application and drying should take place on dry days at temperatures between +5°C and +25°C. Tools should be cleaned with water immediately after fi nishing work. Application during direct exposure to sunlight, in strong winds or high air humidity is not recommended. In order to protect the completely undried paint coating against severe weather conditions, it is recommended to use appropriate protective meshes on scaff olds.
ADDITIONAL OPTIONS: In order to increase the resistance of the paint coat to the growth of algae and fungi (especially while renovating EWI systems and while painting façades in shaded places with increased humidity and with a high concentration of plants), it is recommended to apply a special protective substance along with the paint (additional service). If paint is applied on substrates with cracks with a width of up to 0.3 mm (e.g., small shrinking cracks of the render coat), it is recommended to use paint reinforced with microfi bres (NOVALIT PLAN) for the first painting.
