Polysilicate for cracked substrates

A mineral paint produced based on innovative, low-alkaline polysilicate technology. It is used to create a base coat for NOVALIT F topcoat on difficult (heterogeneous or cracked) substrates, outdoors. It is intended for use on both mineral substrates (such as concrete, lime render, cement-lime render, cement render) and on substrates covered with well-bonded plastic-based renders/plasters. It creates a mineral coating, permanently connected with the substrate, which fills in the micro-cracks and evens non-uniform substrates. Due to the content of special micro-fibres, it efficiently bridges scratches and cracks of the substrate up to 0.3 mm wide. Mineral substrates should be primed with NOVALIT GF before applying the paint.

• Eff ective bridging and sealing of small scratches and cracks
• Mineral nature
• Low-alkaline (pH 8-9.5)
• Resistance to changes of weather conditions during application and setting
• Micro-porous texture, which assures high vapour permeability
• Low surface absorption
• Anti-fungal and algae protection (reduces the growth of algae and fungi)
• For use on both mineral substrates and plastic-based renders/plasters

SUBSTRATE PREPARATION: The substrate should be clean, degreased, dry and sound/stable, as well as 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 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, fi rst 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.
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 – do not dilute.
APPLICATION: The paint should be applied on the substrate with a paint brush or roller until the expected layer thickness is obtained. 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 (hardening) time of the paint applied onto a substrate (at +20°C, 55% RH) is about 24-48 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 setting 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 unset paint coating against severe weather conditions, it is recommended to use appropriate protective meshes on scaffolds.
