Insulating adhesive mortar ANSERGLOB BCX 37 is used for bonding expanded polystyrene (EPS) board to concrete, bricked, foam concrete, cement-sand, cement-lime, gypsum plaster and other mineral surfaces. Adhesive mortar can be used indoors and outdoors of industrial buildings and residential apartments, on terraces, balconies. Attention! For applying on external surface of heat insulation material intermediate adhesive layer, reinforced by fiberglass mesh, it is required to use adhesive mortar ANSERGLOB BCX 40.
Warning: For applying on external surface of heat insulation material intermediate adhesive layer, reinforced by fiberglass mesh, it is required to use adhesive mortar ANSERGLOB BCX 40.
Warning: For applying on external surface mineral wool panels use ANSERGLOB BCX 39 or ANSERGLOB BCX 40.
Warning: ANSERGLOB BCX 40 or ANSERGLOB BCX 41 is necessary used for insultion with XPS.
The surface preparation is realized according to State Standard of Ukraine (DSTU N B A.3.1-23:2013, DSTU N B A.2.6-212:2016) and State Building Codes of Ukraine (DBN В.2.6-162:2010). 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 irregularities must be leveled by plastering mortar ANSERGLOB BCT 20. Before applying substrates with strong sorption must be treated by one of deeply penetrating emulsions ANSERGLOB and exposed for 4 hours. Before applying substrates with low sorption must be treated by ANSERGLOB EG 62 or ANSERGLOB EG 63 BETON KONTAKT and exposed from 3 to 6 hours.
Adhesive mortar ANSERGLOB BCX 37 is applied on internal surface of
board by strips, when wall irregularity is not more than 5 mm and as heat insulation material EPS board are used. Mortar is applied in strips at a distance of 20 mm from the edges of the plate on its perimeter, and then in the middle. Applied strips on the perimeter must be discontinuous so when bonding the plate airlocks are not formed.
By combined (or beacon) method mortar is applied in the case when the surface irregularities of the walls are till 10 mm and by the project using of EPS insulation boards are required. The adhesive mortar is applied to the surface of the heat insulating plate on its perimeter by stripes width of 50-80 mm and a thickness of 5-10 mm, on distance of 20 mm from the edges. Strips must be discontinuous so when bonding the plate airlocks are not formed. In the middle of the plate, in two, four places beacons of size 150-180 mm are applied.
By solid method mortar is applied when the surface of the enclosing structure is smooth, without ledges and hollows, as well as when used as heat insulation material mineral wool boards are used. Layer is applied on all over the surface of the plate and smoothed by notch trowel or spatula of 10-12 mm notch size. Before applying the base layer of adhesive mortar on the heat insulating material, the surface of heat insulating material must be primed by the same adhesive mortar. While applying solid the adhesive mortar must be removed from the edges of heat insulating material for about 10-15 mm. After applying the adhesive mixture, the insulation board is pressed with effort to the surface of the base, so that the adhesive mixture is evenly distributed between the board and the base. If necessary, within 10 minutes after gluing, the position of the insulation plate can be adjusted.
WARNING! In any case, the amount of mortar should be enough to connect plates to the base by at least 60% of their area. The mortar should not fall on the ends of the plates, overage solution must be removed.
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.
While applying facade must be protected from excess humidity (rain, fog).
Average consumption of the mixture is 4,5-5 kg per m2 for bonding EPS, 5-7 kg per m2 for bonding mineral wool plates.
Dry mixture must be poured into container with clear water according to ratio 0,20 – 0,23 liters of water per 1 kg of mixture (5,0– 5,75 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.
