4. Determine the mortar colour
If Zero® bricks are laid correctly, much less mortar is visible than in traditional brickwork, but an unsuitable mortar colour can still be undesirable. For a uniform effect you can choose a matching coloured mortar, e.g. red mortar for a red facing brick. You can also opt for a darker mortar to reinforce the shadow effect of the joint. Many mortar manufacturers offer a wide range of coloured mortars developed especially for joint-free brickwork.
