Are you looking for a fa\u00e7ade that is not only beautiful but also completely safe for the building \u2014 free from algae, mould and damp problems for many years to come? Knauf KATI S Baranek is a silicate textured plaster with a \u201elamb\u201d finish, which, thanks to its naturally high pH, acts as an active biological barrier. This product is designed for developers and contractors who expect more from a fa\u00e7ade than just its appearance \u2014 they expect durability, safety and peace of mind for decades to come.<\/p>\n
Knauf KATI S Baranek is a carefully formulated mixture of an acrylic water-based dispersion, potassium water glass, marble aggregates and mineral fillers. Silicate plaster differs from silicone plaster primarily in its characteristics, which are similar to those of mineral plaster \u2014 it is more \u201ebreathable\u201d and acts more naturally. Its high vapour permeability allows walls to freely release water vapour to the outside, which is particularly important in buildings with external insulation.<\/p>\n
A key advantage of silicate plasters is their naturally high pH, which effectively inhibits the growth of algae and fungi on the fa\u00e7ade \u2014 without the need for additional biocides. Furthermore, Knauf KATI S Baranek is non-combustible, which is of significant importance when selecting materials for external thermal insulation systems using both polystyrene and mineral wool. Available in 1.5 mm and 2 mm grain sizes, it creates a distinctive, delicate \u2018sheep\u2019s wool\u2019 texture \u2014 a classic finish that has stood the test of time on thousands of fa\u00e7ades across Poland and Europe.<\/p>\n
Knauf KATI S Baranek is intended exclusively for external use \u2014 as a facade render in ETICS thermal insulation systems. It is suitable for a wide range of substrates and various types of projects:<\/p>\n
Knauf KATI S Baranek silicate plaster is a product that combines the natural properties of mineral chemistry with modern technology:<\/p>\n
Knauf KATI S Baranek is available in all colours from the Knauf Classic \u201904 colour chart, in two grain sizes: 1.5 mm and 2 mm. The product is supplied in 25 kg buckets, in white or in a tintable version (base A). The wide colour range of the Knauf Classic \u201904 colour chart allows the fa\u00e7ade colour to be matched to any architectural design and the building\u2019s surroundings.<\/p>\n
If, after application, the colour needs to be evened out, it is possible to paint the surface with Knauf Silicone Levelling Paint \u2014 but not until at least 7 days after the plaster has been applied. White plasters painted in the final colour require at least two coats of paint.<\/p>\n
The substrate must be load-bearing, compact, dry, sound and clean \u2014 free from dust, oil, bitumen and other substances that impair adhesion. Layers reinforced with fibreglass mesh (after a minimum of 3 days), as well as concrete and cement-lime plasters-lime plasters (after a minimum of 28 days, moisture content \u2264 4%) must be primed with Knauf Putzgrund in a colour matching that of the plaster.<\/p>\n
Stir the contents of the bucket thoroughly before use, paying particular attention to ensuring the batch numbers match \u2014 this guarantees a uniform colour across the entire fa\u00e7ade. If necessary, the consistency can be gently adjusted with clean water, adding a maximum of 1%. The plaster is applied with a stainless steel trowel to the thickness of the grain, and the \u201elambskin\u201d texture is formed using a plastic trowel. Work should be carried out at temperatures between +5\u00b0C and +25\u00b0C, in dry conditions, avoiding surfaces exposed to strong sunlight and strong winds. Protect the fresh render from rain and excessive drying for at least 24 hours; in conditions of high humidity and low temperatures, this period may extend to 3 days. It is recommended to use protective covers on the scaffolding.<\/p>\n
Knauf KATI S Baranek is the choice for those who value natural, tried-and-tested solutions based on mineral silicate technology.\u00a0 A fa\u00e7ade finished with Knauf KATI S Baranek silicate plaster is not just about aesthetics \u2014 it provides active protection for the building against damp, biological contamination and changing weather conditions, and remains effective for decades without the need for renovation.<\/p>","protected":false},"excerpt":{"rendered":"
