Mechanically remove brittle joints and chip them to a depth of approximately 2 cm, reaching a stable material.<\/p>\n<p>&#x26a0;&#xfe0f; Note: The substrate must be load-bearing, even, and clean, and it should also be insulated against water penetration from below.<\/p>\n<p><strong>Step 2: Joint Filling<\/strong><br \/>\nFill the joints using <strong>Bostik Sperrm\u00f6rtel<\/strong> repair mortar. The mortar sets within approximately 4-5 hours at a temperature of 20\u00b0C.<\/p>\n<p><strong>Step 3: Application of Mineral Slurry<\/strong><br \/>\nApply <strong>K11 Schl\u00e4mme Grau<\/strong> mineral slurry. Ensure the substrate is pre-wetted to a matt-damp condition before application.[\/vc_column_text][vc_message]<strong>Note! The mortar must be applied in at least two working cycles! The second layer should be applied perpendicularly to the first layer. The mortar must cover 100% of the surface intended for sealing. The thickness of each layer should not exceed 2.5 mm at any point.<\/strong>[\/vc_message][vc_column_text]<strong>Step 4.<\/strong><\/p>\n<p>Embed the BOSTIK Ardatape Sanitary Band or KOESTER Flex-Tec 120 sealing tape into the first layer of K11 Schl\u00e4mme Grau waterproofing slurry at wall-floor and wall-wall junctions.<\/p>\n<p><strong>Step 5.<\/strong><\/p>\n<p>Apply the next layer of K11 Schl\u00e4mme Grau mineral slurry only after the first layer has set.

The second layer should be applied perpendicular to the first layer. The slurry must cover 100% of the surface intended for sealing. The thickness of each layer should not exceed 2.5 mm at any point. Extend the slurry onto the floor for a minimum width of 30 cm and onto the adjacent walls.<\/strong>[\/vc_message][vc_column_text]<strong>Step 6.<\/strong><\/p>\n<p>Apply the wide-pore render <strong>K\u00d6ESTER Sanierputz<\/strong> in a single work cycle at a thickness of 20-25 mm. Highly absorbent substrates should be pre-moistened or primed with a diffusion-permitting primer such as <strong>KOESTER Polysil TG500<\/strong> or <strong>BAUMIT SanovaPrimer<\/strong>. Remove any excess material while ensuring the coating is applied evenly. Finally, smooth the render surface.[\/vc_column_text][vc_message message_box_color=\"success\" icon_fontawesome=\"fas fa-question-circle\"]<strong>Fun Fact!<\/strong> In this case, there\u2019s no need to apply a renovation coat since <strong>K\u00d6ESTER Sanierputz<\/strong> is applied directly as the main layer.<\/p>\n<p>However, if you need to use a renovation coat, you can also utilize <strong>K\u00d6ESTER Sanierputz<\/strong>. When used as a renovation coat, it must cover 50% of the surface. In this scenario, the <strong>K\u00d6ESTER<\/strong> system should be applied as follows:<\/p>\n<p>Immediately after priming the substrate with <strong>K\u00d6STER POLYSIL TG 500<\/strong>, apply the renovation coat \"fresh on fresh.\" This renovation coat should be made using <strong>K\u00d6STER Sanierputz grey<\/strong>, mixed with a 10% addition of <strong>K\u00d6STER SB Haftemulsion<\/strong> in the mixing water. The renovation coat should be applied to the substrate at a thickness of approximately 5 mm and should cover a maximum of 50% of the surface (material usage for <strong>K\u00d6STER Sanierputz grey<\/strong> to create the renovation coat is about 3.0 kg\/m\u00b2).[\/vc_message][vc_column_text]<strong>Step 7.<\/strong><\/p>\n<p>At this stage, you can coat the plasters with <strong>KABE Aquatex<\/strong> paints or other paints specifically designed for renovation plasters.[\/vc_column_text][vc_message]<strong>Note!<\/strong><br \/>\nThe air, substrate, and component temperature should range from <strong>+5\u00b0C to +30\u00b0C<\/strong>.[\/vc_message][\/vc_column][\/vc_row][vc_row][vc_column width=\"1\/2\"][vc_single_image image=\"258060\" img_size=\"600x400\" css_animation=\"fadeIn\"][\/vc_column][vc_column width=\"1\/2\"][vc_single_image image=\"258061\" img_size=\"600x400\" css_animation=\"fadeIn\"][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<strong>What You Need for Waterproofing and Renovation?<\/strong><\/p>\n<p>[\/vc_column_text][vc_column_text]<strong>Repair Mortar<\/strong>: Bostik Sperrm\u00f6rtel<\/p>\n<p><strong>Mineral Slurry<\/strong>: K11 Schl\u00e4mme Grau<\/p>\n<p><strong>Sealing Tape<\/strong>: BOSTIK Sanitary Band<\/p>\n<p><strong>Wide-Pore Plaster<\/strong>: Koester Sanierputz<\/p>\n<p><strong>Paint<\/strong>: KABE Aquatex[\/vc_column_text][vc_column_text][\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=\"258149\" img_size=\"full\" alignment=\"center\" css_animation=\"left-to-right\"][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<strong>Wanna know more?<\/strong><\/p>\n<p>[\/vc_column_text][vc_column_text]<strong>We have a team of experts who will gladly assist you.<\/strong><br \/>\nIf you have any additional questions, feel free to call us at <strong>533 343 595.<\/strong>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text][\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n<ul>\n<li>\n<h6>Author: <strong>Anna Kaczmarczyk-Fiuk<\/strong><\/h6>\n<\/li>\n<li>\n<h6>Substantive and Technical Editing: <strong>Szymon Zi\u0105bek<\/strong><\/h6>\n<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Odpadaj\u0105cy tynk na zawilgoconej \u015bcianie.
