APPLICATION

BK-Sil Si&Si is a thin-layered, decorative, pasty, silicate-silicone plaster used for the protection of facade wall surfaces. It is characterized by solid adhesion to the base, exquisite workability, high level of hardness, resistance to fine, and good vapor permeability. It is resistant to UV radiation and atmospheric factors. Due to its characteristic it is recommended for use when renovating old objects or cultural monuments. Thanks to special silicone additives, its water permeability has been drastically reduced in relation to standard silicate plaster. BK-Sil Si&Si is made in two structures and multiple different granulations. BK-Sil Si&Si Rajb – troweled structure (granulation 1.5 and 2 mm) BK-Sil Si&Si Ful – full structure (granulation 1, 1.5, and 2 mm) 

The substrate to which the render is applied must be solid, clean, dry and coated with BK-GrundSilicat primer. Mix BK-SilSi&Si before application and if necessary dilute with a small amount of water up to 1%. The render is applied with a steel trowel with thickness of the largest grain. Depending on the desired structure, the render is then processed with a plastic trowel, namely: Full structure – structured in a circular pattern immediately after application; Reib structure – after application scratch by circular motions until the desired structure is achieved. It is necessary to work evenly and without interruption on continuous wall surfaces. See product datasheet for more detailed instructions.

From +15°C to +30°C, relative humidity max. 70 %. Do not work under direct sunlight, rain or strong wind. The facade must be adequately protected with mesh. High humidity and low temperatures can significantly extend the render bonding time.
