Flexible adhesive ANSERGLOB BCX 46 for marble and mosaic is intended for interior and exterior facing concrete, brick, cement-sand, cement-lime surfaces, as well as surfaces subjected to periodic deformations (atmospheric influences and dynamic loads) with marble and other light-colored stone tiles, as well as glass and mosaic tiles, and tiles larger than 1.0 x 1.0 m. The adhesive can be used for facing of swimming pools and tanks, monolithic floors, accessible roofs, terraces. It can be applied for use with water and electric underfloor heating systems. The adhesive is effective for facing surfaces without removing old tiles ("tile-on-tile" method).
Substrate preparation is carried out according to DSTU-N B A.3.1-23:2013 and DSTU-N B V.2.6-212:2016. The substrate must be sufficiently strong, cleaned of dust, dirt, lime, oils, grease, wax, oil-based or emulsion paints. Remove unsound sections of the substrate. Surface irregularities up to 10 mm should be leveled with adhesive ANSERGLOB BCX 46 at least 24 hours before starting work. Larger wall irregularities should be leveled with ANSERGLOB BCT 20 plaster mortar, larger floor irregularities with ANSERGLOB LFS 69 cement screed, ANSERGLOB LFS 70 cement screed or self-leveling compound ANSERGLOB LFS 72. Highly absorbent substrates must be treated with one of the ANSERGLOB deep penetration primers before work and allowed to dry for 4 hours. Low-absorbent substrates, as well as substrates for "tile-on-tile" facing, should be treated with ANSERGLOB EG 62 or ANSERGLOB EG 63 BETON KONTAKT primer and allowed to dry for 3–6 hours.
Prepared mortar should be spread by tile trowel, spatula or float on cladding surface. After applied mortar is combed by notch trowel or spatula with the U-shaped notches or square notches, which form equal combs of the same altitude on applied surface. Depending on thickness and dimensions of cladding tiles notch size of trowel is selected (for example, for tile size 20x20 cm trowels with the square notch size 6 mm and more are used). Tiles are installed in turn on the surface, covered by adhesive mortar, and pressed evenly. The tile can be moved during 15 min from the moment of installation if required. Thickness of adhesive layer between tile and substrate must be minimally 2 mm to show its full curing. Using handmade tile with unleveled back side and some cut ceramic and stone tile additional spreading of adhesive mortar by rectangular trowel on tile back side is required in order to achieve full contact between tile and substrate. Applying of adhesive mortar on back side of tile is additional measure and does not replace its spreading on the substrate. Joint width between tiles must be not less than 1,5 mm.
Tiles are prohibited to wet preliminary!
Note: Application should be complied at temperature above +5°С and below +30°С. All the mentioned recommendations are effective at temperature of +20°С and air humidity of 60%. Under the other conditions crusting, stiffening and curing time may be changed.
Average consumption of the mixture is 1,3 kg per m2 on 1 mm of layer.
Dry mixture must be poured into container with clear water according to ratio 0,20-0,22 liters of water per 1 kg of mixture (5,0-5,5 liters of water per 1 bag of 25 kg) when at the same time manually or mechanically mixed (by the drill on low revs) to obtain the kindred and elastic mass. After exposing 5 min mortar must be mixed again and used during 2 hours.
