Balconies and terraces require special protection against adverse weather conditions, which can lead to significant structural damage. A commonly used solution is the application of a two-component flexible slurry for sealing. However, mistakes during this process can result in leaks and further damage. This article highlights the most common causes of balcony damage and key factors for effective waterproofing, ensuring these critical building elements are adequately protected from nature's destructive forces.<\/strong>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=\"1\/2\"][vc_single_image image=\"261099\" img_size=\"large\" alignment=\"center\"][\/vc_column][vc_column width=\"1\/2\"][vc_single_image image=\"261098\" img_size=\"large\" alignment=\"center\"][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n <\/p>\n We often don\u2019t realize how crucial proper sealing and protection of a terrace or balcony is until we encounter the first problems. Changing weather conditions can adversely affect the structural elements of a building. There are many methods for insulating balconies and terraces, one of which is using a two-component flexible slurry for sealing.<\/p>\n <\/p>\n Balcony damage is often caused by adverse weather conditions such as rain, snow, and sudden temperature changes. These factors negatively affect the finishing layer and the structure of the balcony slab, especially if there is inadequate waterproofing or poorly sealed parapets. Additionally, the hygroscopic nature of the materials used in the construction of a balcony or terrace\u2014their ability to absorb moisture from the air or ground\u2014plays a significant role. It's also important to note that materials with a porous structure can draw water through capillary action, contributing to the development of damage.<\/p>\n <\/p>\n <\/p>\n Some issues stem from improper selection of waterproofing materials, incorrect application, failure to adhere to the substrate's temperature limits for the applied waterproofing compounds, and neglecting to protect the initially cured waterproofing from excessive heat, especially during summer (high temperatures).<\/p>\n In the example shown in the image, the terrace was waterproofed using a two-component flexible slurry. The material was chosen for its properties, as the terrace is to be finished with composite decking, requiring UV-resistant materials. Flexible sealing tape was selected for securing metal flashing. However, high temperatures caused water evaporation from the materials, which resulted in the tape bulging. Although manufacturers of flexible slurries do not recommend priming the working area of metal flashing, detachment can still occur.<\/p>\n When choosing a two-component flexible slurry for terrace waterproofing, it is essential to select butyl tape and ensure the metal flashing is degreased. Alternatively, a fleece tape can be used in combination with a primer for non-absorbent surfaces (acting as a bonding bridge).<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n <\/p>\n <\/p>\n Two-component flexible slurries are among the most popular materials for waterproofing balconies and terraces. They are particularly effective for surfaces with irregular shapes, as they fill all uneven areas seamlessly. However, special attention must be paid to details that are critical to ensuring effective waterproofing. Key areas to focus on include:<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n This process ensures effective waterproofing of balconies and terraces, protecting them from water and weather-related damage for years to come.[\/vc_column_text][\/vc_column][\/vc_row][vc_column][\/vc_column][vc_row][vc_column width=\"1\/2\"][vc_hoverbox image=\"257902\" primary_title=\"\" hover_title=\"Aquafin 2K\/M-Plus\" hover_btn_title=\"Szczeg\u00f3\u0142y produktu\" hover_btn_color=\"sky\" hover_add_button=\"true\" hover_btn_custom_onclick=\"true\" hover_btn_link=\"url:https%3A%2F%2Fwww.sanier.pl%2Fprodukt%2Faquafin-2km-plus%2F|title:Aquafin%202K%2FM-Plus\"]Aquafin 2K\/M-Plus to innowacyjna, dwusk\u0142adnikowa zaprawa hydroizolacyjna o mineralnej bazie.

How to Waterproof a Balcony Using Flexible Mineral Slurries<\/h3>\n
\n
\nEnsure the surface is even, crack-free, stable, and clean.<\/li>\n
\nUse sealing slurries such as Flex Schl\u00e4mme K11 | Bostik, Kerakoll Aquastop Flex, Schomburg Aquafin 2K\/M Plus, Koester NB Elastik Grey, or Mapei Mapelastic.
\nExtend the waterproofing layer: approximately 30 cm up the wall for unfinished facades or at least the thickness of the screed slope for finished facades.<\/li>\n
\nLay the insulation layer as needed.<\/li>\n
\nApply a screed layer (e.g., Baumit Solido 225 or Baumit Solido 160) on the balcony\/terrace plate.
\nCreate indentations along the edges of the screed to accommodate drip profiles.<\/li>\n
\nSmooth the wall surface for extending the waterproofing using a cement mortar like BOSTIK Sperrmortel Fein or Baumit UniContact adhesive and skim coat.<\/li>\n<\/ul>\n\n
\n
\n
\nTemporarily place the drip profiles to mark fixing points.<\/li>\n
\nStart installing drip profiles at the corners. Secure them using flexible polyurethane sealant or sealing mortar. Account for the thickness of the sealant when preparing indentations. Tighten the screws of the mounting dowels in the drip profiles.<\/li>\n
\nUse products like Schomburg Aquafin 2K\/M Plus, Koester NB Elastik Grey, or Mapei Mapelastic.<\/li>\n\n
