SILCO F – Silicone facade paint
Matt paint intended for performing decorative-protective paint coatings on the external façades. It is especially recommended for painting mineral thin-coat renders exposed to aggressive weather conditions. To be applied both on mineral substrates (such as concrete, traditional cement renders, cement-lime renders and thin-coat mineral renders) and substrates coated with a plastic-based render/plaster. It provides a coating with good vapour permeability and low surface absorption. An absorbent substrate should be primed with HYDROPOR before applying the paint.

• High resistance to adverse weather conditions
• Low surface absorption
• Increased resistance to substrate alkalinity
• Protected against the growth of algae and fungi
• Wide range of colours
• Very high coverage
• 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 efflorescence. 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 flaked 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 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 paint is applied on new mineral substrates, a minimum 2-week curing period is required. Before using the paint in the KABE THERM EPS, KABE THERM AVANT or KABE THERM MW EWI systems, all layers should be applied in accordance with the requirements for external thermal insulation composite system (ETICS). Silicone paint can be applied to thin-coat render only after min. 7 days of curing (at +20°C and 65% RH).
PRIMING: An absorbent substrate should be primed with HYDROPOR 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%). 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 paint 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 3-4 hours. It is recommended to use a special paint roller for façade paints made of woven polyamide with a bristle length of min. 18 mm. Use mechanical spraying only in windless weather.
DRYING: Typical drying time for one layer of paint applied onto a substrate is approx. 3 hours (at air temperature +20°C, 55% RH). 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 finishing 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: 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 microfibres for the first painting (an option available on request). 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).
