Neofil F 50 Flex MINERAL ADHESIVE WITH IMPROVED ADHESION, NO VERTICAL SLIP AND EXTENDED OPEN TIME, HIGH 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 NEOFIL F 50 Flex is a grey or white powder consisting of hydraulic binders, 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 performance and 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 NEOFIL F 50 Flex is used for indoor and outdoor bonding, both on the wall and the floor, of all types of ceramic tiles, such as single-fired, porcelain stoneware, large formats, thin slabs, klinker, fired, ceramic and glassy mosaic, for bonding of stone, marble and reconstituted material as long as dimensionally stable and not sensitive to moisture NEOFIL F 50 Flex is also suitable for bonding insulating materials, such as polystyrene foam, polyurethane foam, cork, glass or rock wool, Eraclit, sound-absorbing 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. NEOFIL F 50 Flex 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 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 NEOFIL F 50 Flex 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-to-

use 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...

building better for laying on traditional or overlapping substrates on existing floors. To make the adhesive highly deformable (S2 according to EN 12004), mix NEOFIL F 50 Flex with polymeric elasticising latex, such as ELASTOKOL by Colmef Srl; the modified adhesive will be suitable for wall and floor installation in all instances where high deformability of the adhesive is required.
