ARMASIL F – Silicone facade paint
Matt paint intended for performing decorative-protective paint coatings on the external facade of buildings, including KABE THERM RENO, KABE THERM SM and KABE THERM SM RENO, KABE THERM ELASTO, KABE THERM AVANT EWI systems based on EPS and KABE THERM MW, KABE THERM IN MW EWI systems based on mineral wool.
It is especially recommended for the renovation painting of surfaces exposed to aggressive atmospheric conditions and requiring high dirt resistance. 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 polymer-based paint coating. It makes up a coating of high vapour permeability and low surface absorption. After wetting the silicone coating, the effect of water particle repelling ’may be observed on its surface. This effect sufficiently protects the facade against precipitation and significantly reduces dirt. Prior to paint application, absorbent substrate should be primed with HYDROPOR.

• To be applied on both mineral substrates and polymer coated surfaces
• Protected against algae and fungi growth
SUBSTRATE PREPARATION: Apply to a sound/stable and clean substrate (without cracks and delaminations), degreased, dry, and free of biological contamination or chemical efflorescence. In case of algae/fungi growth, the substrate should be cleaned mechanically and then wash with water and disinfect with ALGIZID. Any loose layers not bound to the substrate (i.e. loose render or flaked coatings) should be removed. Old and/or dirty substrates should be washed off and degreased with water and CLEANFORCE cleaning agent. For uneven substrates, first use levelling compound and then level the surface with KOMBI FINISZ levelling/finish render. Small unevenness can be levelled out with KOMBI FINISZ levelling/finish render. Absorbent substrates should be primed before finish levelling and smoothing compound and/or and/or levelling compound is applied. If paint is applied on new mineral substrates (such as concrete, lime, cement-lime and cement render), 2-week curing period is required. Before applying the paint in the KABE THERM SM and KABE THERM SM RENO, KABE THERM AVANT and KABE THERM MW EWI systems, all coats of the systems must be made in accordance with the technology of the External Thermal Insulation Composite Systems – ETICS. Silicone paint can be applied to thin-layer render only after 7 days of exposure (at + 20 ° C and 65% relative humidity).
PRIMING: Before paint application, the absorbent substrate should be primed with HYDROPOR. Primer should be dry before applying a paint , curing period lasts about 12 hours. Note: Substrates of low wettability (such as top coats based on polymers or dispersion coatings) should not be primed and should be only washed with water and CLEANFORCE cleaning agent.
PAINT PREPARATION: The packaging contains a ready-to-use product. If required, add a small amount of clean 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 by means of a paint brush, roller or 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 facade paints made of woven polyamide with a bristle length of min. 18 mm. Use mechanical spraying only in windless weather.
DRYING: approx. 3 hours for one paint layer applied to substrate (20°C, 55% RH). Note: Drying time may be longer due to low temperatures and high relative humidity. Protect the fresh paint coating against precipitation and condensation until it dries completely.
USEFUL HINTS: To avoid colour differences, a single batch product should be applied to entire facade or element in one working cycle. To be applied on dry days at temperatures between 5-25°C. All tools to be cleaned with water after finishing work. Application during direct exposure to sunlight, in strong winds or high air humidity is not recommended. To protect wet coating against inclement weather conditions, scaffolding should be covered with some protective netting.
ADDITIONAL OPTIONS: If paint is applied on substrates covered with cracks with a width of up to 0.3 mm (i.e. small shrinking cracks of the top 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 facades in shaded places of increased humidity and with a high concentration of plants), it is recommended to apply a special protective substance along with the paint (additional service).
