Application
FAST GB 1 owing to its characteristic features can be perfectly used for laying cellural concrete blocks and making walls of them.
Characteristics
FAST GB 1 is a water- and frost-resistant thin-coat cement-polymer mortar, easy to glue all elements made of cellural concrete, characteristic for its great adhering properties.
Preparation of the base
FAST GB 1 must be applied on even, clean and ground surfaces of cellural concrete blocks.
Instructions
Pour into a container approximately 5,0 litres of water for 25 kg of dry substance, pour in the contents of the bag stirring simultaneously until an even paste consistence is reached- without any pellets (it is recommended to use a slow-running drill). Leave for about 5 minutes and stir again before applying. The adhesive prepared in this way can be used up within the following 2 hours.
The mortar should be applied onto a block with plain-edge or toothed-edge trowel and correct immediately in the right position. Correction time is up to 10 minutes. After applying the mortar the block should be hammered with a rubber hammer. The excess of the mortar must be delicately removed with a trowel (do not smear over the lateral surface of the gas concrete).
Efficiency
With the thickness of the glued parts of 2,5 mm we can obtain from a bag of 25 kg the following parameters:
block thickness 12 cm - appr. 7,20 m2
block thickness 24 cm - appr. 3,60 m2
block thickness 36 cm - appr. 2,40 m2
Storage
Store in a manufacture (originally) closed packages in a dry room on pallets at the temperature of +5oC up to 25oC.
Suitability for use: 12 months.
