Osmogrout OSMOTIC CEMENTITIOUS MORTAR FOR WATERPROOFING MASONRY AND CONCRETE STRUCTURES IN POSITIVE AND NEGATIVE PRESSURE. FOR INTERIORS AND EXTERIORS. PRODUCT WITH LOW VOLATILE ORGANIC COMPOUND EMISSION RATE. Osmogrout is a ready-mixed gray powder product made up of cement, aggregates with selected granulometry and organic additives. When mixed with water, it creates a fluid mortar that can be applied with a smooth steel trowel or brush, characterized by total water impermeability in conditions of both direct and indirect pressure, as well as strong adhesion to the substrate. ADVANTAGES / FEATURES • Quick and easy installation • For interior and exterior wall and floor coverings 55lb (25 kg) bags – 3,086.4lb (1,400 kg) standard pallet of 56 bags Specific osmotic cementitious covering for waterproofing operations on structures and fabrications in temporary or permanent contact with water. Used for the waterproofing of tanks, elevator shafts, channels, earth retaining walls, foundations, interior and exterior basement walls, wet areas, swimming pools. Also ideal to protect concrete elements exposed to disintegrating salts. WATERPROOFING PLANNING The only way to guarantee the long-lasting performance of ceramic and porcelain tile installations is to properly plan the process. It is therefore advisable to consult the national regulations in force in each country, for example standard UNI 11493 in Italy, which provides all necessary instructions regarding the choice of materials, correct planning, use and installation, so as to ensure all quality, performance and durability standards are safely met. When installing large tiles or low thickness laminated porcelain stoneware slabs, we recommend paragraphs 7.13.8 and 7.13.9 of regulation UNI 11493 be carefully read. Moreover, certain producers of thin slabs provide installation manuals indicating the adhesive classes that need to be used depending on the size, characteristics and intended use of the slabs. Some of the general precautions that need to be followed are listed below as an example. Substrates Before installation, check that substrates are clean, free of loose fragments, properly dried and cured, flat and level, and that mechanical strength requirements based on the intended use have been met. Before application, use a hygrometer to check that the residual humidity in the substrate is maximum 3% CM; on anhydrite screeds maximum 0.5% CM; on anhydrite screeds with heating systems maximum 0.2% CM. (CM = measurement with carbide method hygrometer). Worksite conditions Check the suitability of the temperature, humidity, light conditions etc. at the time of the product’s application. In the case of particularly warm climates (T>95°F) (T>35°C), perform installation in the early hours of the morning. Materials Check that all materials used for tiling (ceramic materials, leveling systems, adhesives, grouts, waterproofing products, etc.) are suitable for the intended use and have been correctly stored. Expansion joints Check that the perimeter, expansion, divider and structural elastic joints have been correctly designed and prepared. Divider joints are normally needed for 20/25 m2 (21.9/27.3yd2) indoor sections, and 9-15m2 (9.84/16.4yd2) outdoor sections. For exteriors, make sure joints are properly waterproofed and sealed. Expansion joints must be waterproofed by inserting the Litoband SK Tape sealing tape, omega-folded inside the joint. Waterproofing systems

To reduce the thickness, allowing the silicone sealant to adhere only to the sides of the tiles, insert the Litogap compressible tubing first, in a diameter suited to the width of the joint. Litokol proposes the neutral cross-linking silicone sealant, Ottoseal S70 for the sealing of elastic joints on terraces, balconies and in swimming pools. To guarantee long-lasting sealing, it is advisable to treat the edges of the joint with Ottoprimer 1216 in the case of balconies and terraces, and Ottoprimer 1218 in the case of tanks and swimming pools. When waterproofing indoor wet areas such as...

Once the layer of Osmogrout has dried, plasters and/or cementitious mortars can be applied to even the surface. Waterproofing Once the layer of Osmogrout has dried, in structures subject to possible hairline cracks and affected by direct and indirect water pressure, apply flexible waterproofing membranes such as Elastocem or Coverflex to further improve sealing and durability. Spread the product at temperatures between 40°F and 95°F Do not add lime, cement or other foreign materials to the product Respect the mix ratio The product, by way of its features, can only be used for rigid...
