Adhesive mortar ANSERGLOB BCX 30 is used for cladding on concrete, brickwork, cement-sand, cement-lime and also gypsum rigid surfaces, monolithic floors by ceramic, concrete tiles and artificial stone which have size not more than 300x300 mm and water sorption more than 1 %. Mortar can be used interior and exterior of industrial buildings and residential apartments, on terraces, balconies.
The surface preparation is realized according to State Standard of Ukraine (DSTU N B A.3.1-23:2013) and State Building Codes of Ukraine (DBN В.2.6-162:2010 and DBN В.2.6-22-2001). Surface must be structurally sound, clean, dry and free from dust, grease, dirt, lime, wax, oil or emulsion paints. Fragile areas of substrate must be removed. Surface irregularity till 10 mm must be leveled by mortar ANSERGLOB BCX 30, big irregularities of walls – by the plastering mortar ANSERGLOB ВСТ 20. Before applying substrates with strong sorption must be treated by one of deeply penetrating emulsions ANSERGLOB and exposed for 4 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 10 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 0,17-0,19 liters of water per 1 kg of mixture (4,25-4,75 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.
