Flex top 100 C2T is a cementitious adhesive (C) improved (2) monocomponent, with high performances, vertical slip-resistant (T), thick-layered, in powder, from C2T class (according to EN 12004), for laying tiles, porcelain tiles, marbles, stones, mosaics etc., on cement mortar substrates, or on existing floorings, suitable for interior or exterior applications. Perfect to the bonding of insulating material like polystyrene etc.. It is composed of hydraulic binders, select quartz sands and specific admixtures.
It can be used for interior and exterior application, for the glueing of ceramic tiles (single fired or double fired, klinker, porcelain tiles, etc) both on vertical and horizontal surfaces. The substrates where the product will be applied can be absorbent surfaces like: cement plasters or mixed lime plasters, cement screeds if only enough dry and cured; interior walls if well fixed painted, gypsum board, heated floorings, waterproofers like poligum and/or liquid fibre sheath of Plastimur s.r.l; on old ceramic floorings and natural stones. The product can not be applied on the following substrates: gypsum, wood, metal, linoleum or rubber floorings, bitumen sheath or on floorings subject to strong vibrations.
To apply the product substrates must be planar, stable, hard, dry, clean and absorbent. They can not be subject to strong shrinkages. Substrates which are damp can lessen the gripping . On gypsum substrates apply a RASOGRESS coat at least 6 hours before. The cementitious screeds must have a cure of 28 days at least. Moisten with water the hot surfaces before the adhesive application.
Mix one sack of kg 25 with lt 6,5 of clean water, and knead with trowel or helix mixer put in the drill at low speed rotations (about 500 r/min) until you obtain a homogeneous lump free paste. Let stand the mixture for about 5 minutes and shake it again briefly before the use.
Apply the adhesive with a notched trowel in the thickness required, taking care to push the product on the substrate with the smooth side of the trowel. Make sure before the application that no film on surface has been formed, in this case apply again a bit of fresh product with the trowel; beat accurately the tiles in order to allow a good wetting of the tile itself. Apply the adhesive on the back of the tiles in order to obtain a complete wetting. In adverse weather conditions (wind, sunlight, high temperatures), the open time could be reduced to a few minutes, so it will be necessary to continuously check that the adhesive has not formed a non-stick glazing, otherwise renew the adhesive. It is not necessary to wet the tiles before the installation, unless they are very dusty. The product can be mixed with TOP LATEX of PLastimur s.r.l, in order to obtain a suitable adhesive to fix tiles on extremely difficult substrates, improving further the level of the adhesion and elasticity. Coatings applied with FLEX TOP 100 C2T don’t have to be washed or suffer rain for 24 hours at least, and must be protected from frost and sunlight for 6 days at least.
GROUTING AND SEALING
The joints between tiles can be grouted after 24 hours on the flooring and after 8/10 hours on the walls.
