Thanks to the innovative product formulation with specific flow and drying properties, the primer and top coat can be applied very efficiently in one work step without intermediate drying time. Thanks to the intelligent combination of different active mechanisms, KEIM Twinstar also offers a high level of protection against algae and fungal growth - without the addition of biocidal ingredients. KEIM Twinstar is therefore particularly suitable for the efficient and sustainable coating of facades in solid construction as well as on insulated surfaces.
KEIM Twinstar also satisfies the requirements of DIN 18 363, 2.4.1 "Dispersion silicate paints". KEIM Twinstar is awarded with Cradle to Cradle Certified Silver and C2C Certified Material Health Certificate™ Gold.
KEIM Twinstar is suitable for facades, both for renovation coats on load-bearing old coatings and for new coats and can also be used on intact ETICS surfaces. KEIM Twinstar is suitable for mineral, organic and mixed substrates.
Please note, this product is NOT suitable for wood substrates, plasto-elastic coatings, saponifiable existing substrates and non-wettable substrates.
SUBSTRATE PREPARATION:
The substrate must be dry, sound, free from chalking, clean and dust-free. Loose parts of existing coatings must be removed mechanically or by high-pressure water jetting. Defective areas must be filled and texture-matched using a suitable repair material. Any sintered layers on new renders must be removed with KEIM Fluat-10 according to instructions. New render areas (repairs) are generally to be pretreated with KEIM Fluat-10 according to the specifications in the Technical Data Sheet.
Algae, fungi or lichens must be removed professionally, thoroughly and without residues. After cleaning and drying of the surface, KEIM Algicid-Plus is used for disinfection. After a reaction time of at least 24 hours, the treated disinfected surface can be refinished.
Alternatively, biocide-free pre-treatment or cleaning is also possible. In this case, KEIM Alkaclean is used for alkaline facade cleaning. The application is carried out according to the technical data sheet KEIM Alkaclean. Please note: Surfaces treated with KEIM Alkaclean must be rinsed with water. Direct reworking of the surfaces without re-washing is not possible. The instructions for waste water disposal and exposure time must be observed in accordance with the KEIM Alkaclean technical data sheet.
Dormant cracks in the substrate with a crack width of up to 0.25 mm can be coated without a separate additional coat. For dormant cracks in the substrate with a crack width of 0.25 to 0.5 mm, an additional coat of KEIM Twinstar must be applied before the actual coating.
APPLICATION CONDITIONS:
Ambient and substrate temperature ≥ 5°C during application and drying. Do not apply in direct sunlight or on sun-heated substrates. Protect surfaces from direct sun, wind and rain during and after application.
Stir KEIM Twinstar thoroughly before application.
APPLICATION:
KEIM Twinstar can be applied by brush, roller or airless spraying. For airless application, a nozzle ≥ 539 is recommended (without insertion filter). KEIM Twinstar is to be applied undiluted. To ensure proper function, an application quantity of at least 0.4 kg/m² must be observed. For a sufficient and homogeneous material application, it is recommended to apply the coating as follows:
