Therefore, careful attention to the sand-to-cement ratio is essential; too much cement leads to surface cracking and reduced flexibility, while too much sand weakens the overall strength. This mortar is an economical and reliable choice for dry, low-moisture floors and walls. However, its curing time is relatively long, and its adhesive uniformity is not as consistent as that of ready-mixed adhesives.<\/span><\/p><h5 class=\"ds-markdown-paragraph\"><strong><span class=\"\">Tile adhesive (powder or paste):<\/span><\/strong><\/h5><p class=\"ds-markdown-paragraph\"><span class=\"\">Tile adhesive offers significant advantages over traditional mortar. For example, it provides higher adhesive uniformity, reduces the risk of cracking and loosening, allows faster installation, and offers better water resistance. These characteristics make it perform better in wet environments and high-traffic floors and walls. On the other hand, proper application requires careful attention to the correct thickness and thorough surface preparation.<\/span><\/p><h5 class=\"ds-markdown-paragraph\"><strong><span class=\"\">Primers and coating materials:<\/span><\/strong><\/h5><p class=\"ds-markdown-paragraph\"><span class=\"\">Primers and coating materials play a reinforcing role in adhesion and prepare the substrate for tile installation. Specifically, on surfaces with paint, previous coatings, or uneven plasterwork, primers reduce the likelihood of tile detachment and increase the durability of the work. However, these materials alone do not bear mechanical loads and must be used together with mortar or adhesive. Furthermore, using primers or coating materials alone is not cost-effective, because without mortar or adhesive, the floor and wall cannot withstand pressure and moisture, potentially leading to premature repairs.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-0064ea4 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"0064ea4\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-c7d65c3\" data-id=\"c7d65c3\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-54e7572 elementor-widget elementor-widget-heading\" data-id=\"54e7572\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Concrete substrates and their requirements \u2014 accordingly, what you need to know<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-be9aee5 elementor-widget elementor-widget-text-editor\" data-id=\"be9aee5\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Many floors and walls ultimately come down to concrete.

Typically, in residential or commercial renovations, we encounter surfaces that have already been tiled or have layers of old paint, plaster, or mortar remaining. In such cases, proper substrate preparation becomes even more critical, because the new surface must be built on a strong, repaired, and ready-to-use foundation.<\/span><\/strong><\/p><h5 class=\"ds-markdown-paragraph\"><strong><span class=\"\">Removing previous layers<\/span><\/strong><\/h5><p class=\"ds-markdown-paragraph\"><span class=\"\">Before any action is taken, unstable and unsuitable layers must be completely removed. Loose tiles, delaminated mortar, peeling paint, or old coatings lack the necessary adhesion, and leaving them in place directly threatens the integrity of the new tiling. Therefore, installing tiles over these layers will only cause the previous failure to recur in a shorter period of time.<\/span><\/p><p class=\"ds-markdown-paragraph\"><span class=\"\">For removing these layers, mechanical tools are typically used; old tiles are chiseled off with a demolition hammer, chisel, or pick, and leftover mortar is cleaned away with a scraper, grinder, or suitable sander. For paint and surface coatings, sanding equipment or approved solvents are used to prepare the surface for new substrate work. The goal of this stage is to reach a bare, solid, and bondable substrate.<\/span><\/p><h5 class=\"ds-markdown-paragraph\"><strong><span class=\"\">Repairing damaged sections<\/span><\/strong><\/h5><p class=\"ds-markdown-paragraph\"><span class=\"\">Old surfaces often have cracks, porosity, corrosion, or loose areas. These sections must be repaired before any further work, so that the subsequent tiling does not suffer from failure or loosening. Accordingly, any structural weakness in this stage will be transferred directly to the tiles and reduce the durability of the installation.<\/span><\/p><p class=\"ds-markdown-paragraph\"><span class=\"\">For repair, the loose areas are first opened up using a chisel, scraper, or pick until sound material is reached. After cleaning with a brush or blower, the cracks are filled with repair mortar, cement-based resin, or high-strength filler. For deep voids and depressions, gradual layering is carried out until the surface is level with the original substrate. In cases of extensive damage, using mesh or a reinforcing layer before mortar application can improve overall stability. The goal of this stage is to create a level, solid, and ready surface to receive primer, adhesive, or mortar.<\/span><\/p><h5 class=\"ds-markdown-paragraph\"><strong><span class=\"\">Controlling and removing residual moisture<\/span><\/strong><\/h5><p class=\"ds-markdown-paragraph\"><span class=\"\">Existing moisture in the floor or wall is one of the primary causes of tiling failure in renovation projects. Ignoring this issue can lead to efflorescence, tile blistering, reduced adhesion, and even decay of underlying layers. Therefore, removing moisture before any substrate preparation or tile installation is essential.<\/span><\/p><p class=\"ds-markdown-paragraph\"><span class=\"\">To control and remove moisture, the surface and subsurface are first checked for leaks or dampness using a moisture meter. If active moisture is found, the source (pipe, joint, surface infiltration, or structural crack) is identified and stopped. Damp surfaces are then dried using warm air flow, dehumidifiers, or controlled heating. In areas where moisture may return, cementitious waterproofing layers or penetrating coatings are applied to prevent salt transfer to the next layer. For deep-seated moisture, injecting waterproofing materials or reapplying localized insulation is a more appropriate solution.<\/span><\/p><p class=\"ds-markdown-paragraph\"><span class=\"\">The final goal of this stage is to create a dry, isolated, and stable surface so that tile adhesive or mortar can perform properly and previous damage does not recur.<\/span><\/p><p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Tiling on old surfaces requires more care and preparation than on new substrates; however, if these principles are followed, the final result will be even more durable than many new-build projects.<\/span><\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-062a4c4 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"062a4c4\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-df9937f\" data-id=\"df9937f\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-ec4e4cf elementor-widget elementor-widget-image\" data-id=\"ec4e4cf\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"624\" height=\"624\" src=\"https:\/\/bidak-co.com\/wp-content\/uploads\/2025\/11\/Picture2.jpg\" class=\"attachment-large size-large wp-image-9026\" alt=\"\u0632\u06cc\u0631\u0633\u0627\u0632\u06cc \u06a9\u0627\u0634\u06cc\u200c\u06a9\u0627\u0631\u06cc\" srcset=\"https:\/\/bidak-co.com\/wp-content\/uploads\/2025\/11\/Picture2.jpg 624w, https:\/\/bidak-co.com\/wp-content\/uploads\/2025\/11\/Picture2-300x300.jpg 300w, https:\/\/bidak-co.com\/wp-content\/uploads\/2025\/11\/Picture2-150x150.jpg 150w, https:\/\/bidak-co.com\/wp-content\/uploads\/2025\/11\/Picture2-600x600.jpg 600w, https:\/\/bidak-co.com\/wp-content\/uploads\/2025\/11\/Picture2-100x100.jpg 100w\" sizes=\"(max-width: 624px) 100vw, 624px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-5764215 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"5764215\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-66b122d\" data-id=\"66b122d\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-92aad3b elementor-widget elementor-widget-heading\" data-id=\"92aad3b\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">How temperature and environmental conditions affect substrate preparation \u2014 accordingly, key considerations<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-63f0816 elementor-widget elementor-widget-text-editor\" data-id=\"63f0816\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">After examining repair, waterproofing, and moisture control on old surfaces, it is necessary to address another factor that directly affects the quality of substrate preparation and the durability of tiling: environmental conditions.
