Silikoll MINERAL ADHESIVE WITH IMPROVED ADHESION, NO VERTICAL SLIP AND EXTENDED OPEN TIME, GOOD WORKABILITY. SUITABLE FOR PROFESSIONAL LAYING OF CERAMIC TILES, MOSAICS AND STABLE NATURAL STONES ON WALLS AND FLOORS. FOR INDOORS AND OUTDOORS. Technical Data Sheet – Rev. 09/2018 DESCRIPTION SILIKOLL is a professional powder adhesive consisting of hydraulic binders, selected mineral fillers, synthetic resins and special additives. Mixed with water, it is transformed into a thixotropic product with easy workability and extended open time that facilitates laying operations, high adhesion to materials normally used in construction, applicable upright without the risk of sagging or tiles slipping and free from particular shrinkage during hardening. For thicknesses up to 10 mm. Classification according to European standard EN 12004 – C2TE · Cement adhesive (C) improved adherence (2), no vertical slip (T), with extended open time (E). FIELDS OF APPLICATION SILIKOLL is used for indoor and outdoor bonding, both on the wall and the floor, of all types of small and medium format ceramic tiles, such as single-fired, porcelain stoneware, klinker, fired, ceramic and glassy mosaic, for bonding of stone, marble and reconstituted material as long as dimensionally stable and not sensitive to moisture SILIKOLL is also suitable for bonding insulating materials, such as polystyrene foam, polyurethane foam, cork, glass or rock wool, Eraclit, soundabsorbing panels, etc.. It can be applied on all cementitious substrates normally used in construction, such as plaster, concrete, cellular concrete, self-levelling screed, cementitious screeds also subjected to intense traffic, on quick-drying screeds made with mineral hydraulic binder NEOCEM or on quick-drying ready-to-use screeds and compensated shrinkage made with NEOCEM PRONTO. SILIKOLL can be used for laying floors or coverings on gypsum or plasterboard substrates, as long as it is supported rigidly, on anhydrite screeds (after applying the insulating PRIMER A 16), for laying floors on heating screeds (only for tiles with a format that does not exceed 900 cm2), for overlapping installation on existing ceramic or marble floorings adequately prepared (with formats up to 900 cm2) and for laying floors on elastomer or elastic cementitious waterproofing membranes. To make the adhesive deformable or highly deformable (S1/S2 according to the EN 12004 standard), mix SILIKOLL with ELASTOKOL polymeric elasticising latex, in total or partial replacement of the mixing water. SUBSTRATE PREPARATION The substrates must be sufficiently dry and seasoned, mechanically resistant, flat, solid, compact, free of crumbling or inconsistent parts, without any dust and greasy substances, oil, paint, wax and any material that could compromise perfect product adhesion. The cementitious substrates must not be subjected to shrinkage after laying the tiles and, therefore, they must have already completed the hygrometric shrinkage that can be evaluated in one or two weeks for each cm of thickness for the plaster and in at least 28 days of total curing for cementitious screeds, unless they are made with quick-drying ready-touse screed and NEOCEM PRONTO compensated shrinkage or with NEOCEM hydraulic binder for quick-drying screeds. Anhydrite screeds must be perfectly hardened, clean, dry (maximum residual humidity 0.5%) and must be treated, after sanding, with insulating primer based on synthetic resins in aqueous dispersion PRIMER A 16. Always treat with PRIMER A 16 for direct applications on plaster or plasterboard. Very porous, highly absorbent and superficially crumbling

surfaces must be treated with RASOTECH PRIMER CONSOLIDANTE consolidating impregnating agent so as to reduce the absorption of the screed and improve workability and adhesion of SILIKOLL. APPLICATION To prepare the mixture, pour a 25 kg bag of SILIKOLL in a clean container with 6.5-7 litres of clean water and mix until smooth and free of lumps. Let the mixture rest for a few minutes, remixing quickly before use. This mixture remains workable for 6-8 hours at a temperature of +23 °C. Apply a zero layer of adhesive on the substrate with a smooth spatula, to ensure better adhesion and lengthen the...
