Litokol K18 CEMENTITIOUS ADHESIVE FOR THE INSTALLATION OF CERAMIC AND PORCELAIN TILES ON INTERIOR WALLS AND FLOORS, AND ON EXTERIOR FLOORS. PRODUCT WITH VERY LOW VOLATILE ORGANIC COMPOUND EMISSION RATE. ADVANTAGES / FEATURES • Product with very low volatile organic compound (VOC) emission rate. Complies with class EC1PLUS according to the EMICODE protocol and class A+ (Émission dans l’air intérieur - French Regulations) • Maintains excellent workability over time, without any bothersome thickening 20 kg bags - 1,200 kg standard pallet Intended uses Interiors - exteriors Floors and walls Residential, public, commercial building INSTALLATION 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. Suitable materials Ceramic and porcelain tiles Terracotta - Clinker Marble – Granite – Stone Natural stones Double fired Single fired Porcelain stoneware Suitable substrates Cement screeds Self-levellers Skim coats Plasters Concrete Gypsum Gypsum and anhydrite 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. Worksite conditions Check the suitability of the temperature, humidity, light conditions etc. at the time of the product’s application. Materials Check that all materials used for tiling (ceramic materials, levelling 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 indoor sections, and 9-15m2 outdoor sections. For exteriors, make sure joints are properly waterproofed and sealed. Back-buttering For exterior installations, large tiles, floors with intense or heavy traffic, vibrating supports and situations exposed to high temperature fluctuations, the adhesive mortar must be applied to both the substrate and the back of the tiles so as to obtain a solid bed of adhesive without any air bubbles. Joints In any type of ceramic and porcelain tiling, suitably sized joints must be created based on the following parameters: • Type, format and size tolerance of tiles • thermal expansion coefficients of tiling materials • mechanical properties of installation materials • position and trajectory of joints Cementitious adhesi

• mechanical features of substrate • Intended use and operating conditions Butt joints are not allowed. Any plastic spacers must be removed before grouting. For example, it can also be used to install suitable materials in the following areas: Interior floors in residential and public/commercial settings (pedestrian areas) Substrates Cement or Litocem/Litocem Pronto-based non-heating screeds Sulphate-based (anhydrite) non-heating screeds (1) Interior walls in residential, public/commercial and industrial settings Substrates Lime/cement plaster Gypsum-based plaster (1) Fibre cement and...

Spread the mix onto the substrate using the smooth part of the trowel to create a layer approximately 1 mm thick. Immediately afterwards, apply the product using the notched part of the trowel. The trowel notch size will depend on the size of the tiles. A back coverage of 65-70% of slabs is nonetheless required for interior installations, and 100% of slabs for exterior installations or floors subject to heavy traffic. In exterior installations or areas subject to high stress, the adhesive should also be applied to the back of the slabs (back-buttering method). The tiles must be laid on the...
