3/12: Choosing the right mortar

Choosing the right mortar

The quality of joint-free brickwork with Zero® facing bricks depends not only on the quality of the brick, but also on the quality of the mortar. A ZERO brick comes with an oval hole at the centre in the lowered mortar bed. When laying, the mortar “creeps” along both the bottom and the top in this opening. The result: the laying surface is increased, which significantly raises the bonding value. This means that a normal-quality mortar is more than adequate for ZERO brickwork.


Zero® bricks must be wind-dry when used. During hot weather, prevent the mortar from drying out by moistening the brickwork to improve bonding.
