Wall, Plaster & Masonry Systems
Shows two separate KraftBau ready-mix masonry mortar systems as fixed cards for laying AAC blocks and pumice blocks or bricks.
System summary
The thin-bed application of AAC blocks and the masonry needs of pumice blocks and bricks are not the same. This page presents KR-120 AAC block masonry mortar and KR-121 pumice block and brick masonry mortar as two separate fixed systems.
Application
Steps are listed in application order. For consumption, layer thickness and waiting times, refer to the products' current technical data sheets (TDS).
Select the AAC block or pumice block/brick system; check the load-bearing substrate and the first course level before application.
Clean off dust, debris and any residues that reduce adhesion; set aside damaged blocks or blocks with distorted geometry.
Use KR-120 for AAC blocks and KR-121 for pumice blocks and bricks.
Check the courses horizontally and vertically; complete the mortar beds and curing conditions according to the product technical information.
System options
Each option is a complete whole with its own products; products from different options are not combined in a single system.
Only KR-120 is shown on the AAC block card; only KR-121 on the pumice block and brick card. The products are not presented as alternatives to each other for the same block type.
System 1
The fixed thin-bed system using KR-120 KRAFT AAC BLOCK MASONRY MORTAR for laying AAC blocks.
Used when the wall will be built from AAC blocks and a thin-bed masonry mortar is required.
KR-121 is not shown as an alternative on this card; the block type is not matched with the wrong product.
System 2
The fixed system using KR-121 KRAFT PUMICE BLOCK AND BRICK MASONRY MORTAR for laying pumice blocks, bricks, pressed bricks and suitable blocks.
Used when the wall will be built from pumice blocks, bricks or the blocks within the product's scope.
KR-120 is not shown as an alternative on this card; the AAC block system is kept separate.
