Water penetrating walls or foundations is not chemically neutral. In addition to aggressive substances that may be leached from the ground, this water contains certain amounts of dissolved chlorides, sulfates, and nitrates. These substances, due to ineffective insulation, infiltrate the embedded elements of the building. Subsequently, moisture is drawn upward through the pores (capillaries) of the material, transporting these salts to higher sections of the structure. This process leads to visible dampness, salt efflorescence, discoloration, peeling paint coatings, and flaking plaster. If left unaddressed, it can result in the deterioration of the masonry itself.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"mb-2 flex gap-3 empty:hidden -ml-2\">\n<div class=\"items-center justify-start rounded-xl p-1 flex\">\n<div class=\"flex items-center\"><\/div>\n<\/div>\n<\/div>\n<p style=\"text-align: justify;\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-3633 aligncenter\" src=\"https:\/\/sanier.pl\/wp-content\/uploads\/2017\/04\/5.jpg\" alt=\"5\" width=\"842\" height=\"551\" srcset=\"https:\/\/www.sanier.pl\/wp-content\/uploads\/2017\/04\/5.jpg 842w, https:\/\/www.sanier.pl\/wp-content\/uploads\/2017\/04\/5-800x524.jpg 800w, https:\/\/www.sanier.pl\/wp-content\/uploads\/2017\/04\/5-300x196.jpg 300w, https:\/\/www.sanier.pl\/wp-content\/uploads\/2017\/04\/5-768x503.jpg 768w, https:\/\/www.sanier.pl\/wp-content\/uploads\/2017\/04\/5-700x458.jpg 700w\" sizes=\"auto, (max-width:767px) 700px, (max-width:842px) 100vw, 842px\" \/><\/p>\n<p style=\"text-align: justify;\">\u00a0\u00a0\u00a0 Effective counteraction and renovation of damp and salt-contaminated walls is a fairly complex process, requiring the elimination of the source of moisture, drying the walls, and, most importantly, removing harmful salts from them. A proven solution for extracting salts from walls is the use of specially developed MINERALIT RESTAURO renovation plasters, certified by WTA for their ability to accumulate harmful salts. Which might be the key to fight with salt efflorescence.<\/p>\n<div class=\"column one-second mobile-one\"><div class=\"mcb-column-inner\"><\/p>\n<p>2. <strong>Key Causes of Wall Moisture<\/strong><\/p>\n<div class=\"flex max-w-full flex-col flex-grow\">\n<div class=\"min-h-8 text-message flex w-full flex-col items-end gap-2 whitespace-normal break-words text-start [.text-message+&amp;]:mt-5\" dir=\"auto\" data-message-author-role=\"assistant\" data-message-id=\"fd8405ba-ed10-4af7-8fc9-3a3be32fba2e\" data-message-model-slug=\"gpt-4o\">\n<div class=\"flex w-full flex-col gap-1 empty:hidden first:pt-[3px]\">\n<div class=\"markdown prose w-full break-words dark:prose-invert light\">\n<ul>\n<li>The influence of groundwater penetrating the walls due to the absence or damage of horizontal and vertical insulation.<\/li>\n<li>Moisture from inflowing water.<\/li>\n<li>The effect of rainwater (both direct and indirect).<\/li>\n<li>Flooding caused by installation failures.<\/li>\n<li>Moisture condensation resulting from improper wall thermal insulation, often combined with poor room ventilation.<\/li>\n<\/ul>\n<p>This situation can also be exacerbated by the use of inappropriate materials in previous repairs, changes in the use of the building, variations in groundwater levels, and similar factors.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"mb-2 flex gap-3 empty:hidden -ml-2\">\n<div class=\"items-center justify-start rounded-xl p-1 flex\">\n<div class=\"flex items-center\"><\/div>\n<\/div>\n<\/div>\n<p><\/div><\/div>\n\n<div class=\"column one-second mobile-one\"><div class=\"mcb-column-inner\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3634\" src=\"https:\/\/sanier.pl\/wp-content\/uploads\/2017\/04\/6.jpg\" alt=\"6\" width=\"660\" height=\"544\" srcset=\"https:\/\/www.sanier.pl\/wp-content\/uploads\/2017\/04\/6.jpg 660w, https:\/\/www.sanier.pl\/wp-content\/uploads\/2017\/04\/6-300x247.jpg 300w, https:\/\/www.sanier.pl\/wp-content\/uploads\/2017\/04\/6-350x288.jpg 350w\" sizes=\"auto, (max-width:767px) 660px, 660px\" \/><\/div><\/div>\n\n<p><!--nextpage--><\/p>\n<p style=\"text-align: justify;\">3. <strong>Building Salts and Their Destructive Impact on Construction Materials<\/strong><\/p>\n<p>The most commonly encountered salts in construction are chlorides, nitrates, nitrites, carbonates, and sulfates. These form as a result of the biological and chemical corrosion of rocks in the soil, as well as the natural decomposition of rock-forming minerals. The destructive effect of building salts operates in several ways and is always linked to the presence of moisture in structures. Salts infiltrate the structure through water, entering via various routes: capillary rise from the ground, rainwater, or leaks from faulty sewage systems. Another source of salinity can be chemicals used to protect wooden roof trusses; when washed out, these can act as harmful building salts on wall elements.<\/p>\n<p>The destructive effect of salts arises during the crystallization process within the evaporation zone of moisture (as walls dry). The increase in salt volume during crystallization generates significant stress, causing even materials with high mechanical strength to ultimately deteriorate, especially since this process repeats over time. Additionally, during winter, repeated freeze-thaw cycles in wet walls occur, exacerbated by the hygroscopic nature of salts, which absorb moisture from the air. This further increases the moisture content in the walls, promoting biological corrosion.<\/p>\n<p style=\"text-align: justify;\">4. <strong>Analysis of Causes and Selection of a Renovation Method (Expert Assessment)<\/strong><\/p>\n<p>Each building must be treated individually. This approach enables the selection of the most suitable drying method for the walls, one that ensures a lasting reduction of moisture to an acceptable level. This, in turn, allows for continued trouble-free use of the structure, following the completion of other necessary repairs and renovations.<\/p>\n<p>The drying process should always be preceded by a thorough analysis of the building's current condition and an investigation into the causes of the dampness.<\/p>\n<p style=\"text-align: justify;\">5. <strong>What is the WTA Certificate and How is it Issued?<\/strong><\/p>\n<p>The WTA Certificate is granted to products (in this case, plasters) that meet specific requirements set by WTA (Wissenschaftlich-Technischen Arbeitsgemeinschaft f\u00fcr Bauwerkhaltung und Denkmalpflege e.V.), the German Scientific and Technical Association for Building Maintenance and Monument Preservation. This certification is based on tests conducted in independent, certified laboratories. The quality of these plasters is assessed objectively, rather than relying on promotional claims by manufacturers.<\/p>\n<p>The aforementioned WTA guidelines are instructions that define the requirements for renovation plasters and provide application recommendations. WTA instructions precisely classify the levels of wall salinity into low, medium, and high, based on the concentrations of chlorides, sulfates, and nitrates in the tested wall samples. When renovating historic buildings, materials with this Certificate that meet the strict WTA guidelines should be prioritized.<\/p>\n<p>KABE Poland Paints has received a new WTA Certificate for their MINERALIT RESTAURO renovation plasters, designed to restore damp and salt-contaminated walls, commonly found in many older buildings.<\/p>\n<p>6. <strong>MINERALIT RESTAURO Renovation Plasters by KABE Paints<br \/>\n<\/strong><\/p>\n<div class=\"flex max-w-full flex-col flex-grow\">\n<div class=\"min-h-8 text-message flex w-full flex-col items-end gap-2 whitespace-normal break-words text-start [.text-message+&amp;]:mt-5\" dir=\"auto\" data-message-author-role=\"assistant\" data-message-id=\"e5cec6e8-a7e0-4ea3-ab38-60dea117b77e\" data-message-model-slug=\"gpt-4o\">\n<div class=\"flex w-full flex-col gap-1 empty:hidden first:pt-[3px]\">\n<div class=\"markdown prose w-full break-words dark:prose-invert light\">\n<p>The MINERALIT RESTAURO system consists of a range of products designed for manual or machine application of renovation plaster coatings on salt-contaminated walls, both indoors and outdoors (above ground level). It is particularly recommended for the restoration of historic buildings but is also suitable for standard plastering work. This system allows the creation of a plaster coat with a high pore volume, enabling it to absorb significant amounts of harmful salts present in damp walls. It is characterized by reduced sensitivity to varying wall absorbency levels (e.g., wide joints in walls made of stone). The system also facilitates the application of thick plaster coatings, which can vary across the wall surface.<\/p>\n<p>The MINERALIT RESTAURO renovation plaster system by KABE Paints includes the following products:<\/p>\n<ul>\n<li><strong>MINERALIT RESTAURO TB<\/strong> \u2013 Renovation cement-based preliminary throw-on mortar,<\/li>\n<li><strong>MINERALIT RESTAURO TW<\/strong> \u2013 Renovation leveling plaster mortar,<\/li>\n<li><a href=\"https:\/\/farbykabe.pl\/dokumenty\/mineralit-restauro-tu-renowacyjna-uniwersalna-zaprawa-tynkarska\/\" target=\"_blank\" rel=\"noopener\"><strong>MINERALIT RESTAURO TU<\/strong><\/a> \u2013 Renovation universal plaster mortar.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"mb-2 flex gap-3 empty:hidden -ml-2\">\n<div class=\"items-center justify-start rounded-xl p-1 flex\">\n<div class=\"flex items-center\"><\/div>\n<\/div>\n<\/div>\n<p><strong>7. Salt efflorescence, summary<\/strong><\/p>\n<p>Although MINERALIT RESTAURO renovation plasters are not a \"universal solution\" for all types of problems, they are an effective method for achieving a visually appealing, aesthetically pleasing fa\u00e7ade that is protected against further degradation. Most importantly, this is a long-lasting protection that cannot be achieved with traditional cement and\/or lime plasters. It is essential to emphasize that such results can only be achieved if the causes of wall degradation are accurately identified, the appropriate technology is correctly chosen, and construction work is carried out in accordance with guidelines and standards developed through years of experience. That's the way of dealing with salt efflorescence.[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text css=\"\"] Do you have a problem with salt efflorescence in your building?
