Finishing grey plastering mortar ANSERGLOB ВСТ 22 is a high plastic mixture with small grain size, is used for thinlayer high quality finishing of all mineral rigid surfaces and also on substrates of plastering mortar ANSERGLOB BCT 20 or similar mortar.
It is effective for repairing the cracks, fisheyes, hollows and other defects on the surface less than 5 mm in depth. Finishing grey plastering mortar ANSERGLOB ВСТ 22 can be applied at interior and exterior surfaces, in industrial and residential areas and also under high wet conditions.
It is recommended for decorative finishing of the facades and interior design with creation of different factures.
The surface preparation is realized according to State Standard of Ukraine (DSTU N B A.3.1-23:2013) and DSTU N B A.2.6-212:2016. The surface must structurally sound, cleaned up from the dust, dirt, lime, grease, oil or emulsion paints. The surface irregularities till 5 mm must be leveled by the plaster mortar ANSERGLOB ВСТ 22, big irregularities of the walls – by the plastering mortar ANSERGLOB ВСТ 20. Before applying the plaster the substrates with strong water sorption must be treated by one of the deep penetrating emulsions ANSERGLOB and exposed for 4 hours. The substrates with low water sorption must be treated by adhesion emulsion ANSERGLOB EG 62 and exposed for 3-6 hours.
Finishing plastering mortar is applied on the surface with stainless float or spatula. The maximal thickness of a applied layer must be not more than 5 mm, but minimal not less than 1,5 mm. While applying with spatula there must be no tracks when moving in the opposite direction. 3 days before applying the plastering mortar must be filled small hollows and irregularities by starting plastering mortar ANSERGLOB BCT 20. In the order to obtain smooth surface after 5-10 min (depending on surface origin and weather condition) of finishing layer application, it is required to make complete leveling of surface with stainless or plastic float. After 5-10 min it is required to use rubber roller with desired texture or other tool to obtain the textured surface of application of finishing layer. Average curing time of plastering mortar is 24 hours.
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.
Consumption of the mixture is 1,4-1,5 kg per m2 on 1 mm of permanent layer.
Dry mixture must be poured into container with clear water according to ratio 0,22-0,24 liters of water per 1 kg of mixture (5,5,3-6,0 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 with required consistency. After exposing 5 min it must be mixed again and used during 2 hours. While applying constancy of mortar must be regulated by mixing but not by adding the water.
