Features & Benefits

• Innovative product formulation with specific flow and drying properties
• Primer and top coat can be applied very efficiently in one work step without intermediate drying time
• Intelligent combination of different active mechanisms
• Offers a high level of protection against algae and fungal growth - without the addition of biocidal ingredients
• Particularly suitable for the efficient and sustainable coating of facades in solid construction as well as on insulated surfaces
• Also satisfies the requirements of DIN 18 363, 2.4.1 "Dispersion silicate paints"
• Awarded with Cradle to Cradle Certified Silver and C2C Certified Material Health Certificate Gold
• 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
• Suitable for mineral, organic and mixed substrates
• Not suitable for:
• wood substrates; plasto-elastic coatings; saponifiable existing substrates; 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 Ätzflüssigkeit (lime remover) according to instructions.

New render areas (repairs) are generally to be pretreated with Keim Ätzflüssigkeit (lime remover) 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.

For biocide-free pre-treatment or cleaning, contact our technical team on 0113 2455450 (option 2) or send a message to [email protected] with details of your project so that we can recommend a suitable product.

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

Stir up Keim Twinstar thoroughly before application.

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.

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:

1. Material application: Apply and spread the paint with the roller in a criss-cross pattern. (Approx. value: take up and distribute material approx. 3-4 times per m²)
2. Material application: Immediately after the first material application, apply additional material with the paint roller to the still wet paint layer, rolling vertically in one direction

Note: Intermediate drying time: none

Consumption

Approx. 0,45 kg/m² for a finished coated surface.

These material consumption values are guide values for smooth substrates. Exact consumption values must be determined by means of test areas.

Cleaning of Tools

Clean immediately with water.
