Mortar


Render: one square metre in stretcher bond with 10 mm joints, drawn from the photograph of the brick. The small image is the photograph the render is drawn from. Mortar colour changes the wall as much as the brick does: Natural grey is the usual choice; the others are named as specifications name them.

QuestionsSizes, colour on screen, testing, samples
Are the dimensions exact?
No. Dimensions are nominal averages. Natural stone and its finishing produce variation in size and edge between units and between batches; allow for it in setting out and specify a joint that absorbs it.
Will the colour on screen match the brick?
Not exactly. Product images are prepared from photographs of the brick and presented in a studio setting, and screens differ. Reserve a sample and view it in daylight before specifying.
Has this brick been tested to Australian standards?
Testing to AS/NZS 4456 methods is under way with an accredited laboratory. Results are published on this page and in the Product Technical Statement as they are issued. Until then we state no grade.
How do I get a sample?
Reserve up to three bricks online. We set them aside at the Richmond showroom free of charge and email you when they are ready. Practices outside Melbourne with a project can ask for samples to be posted.
Natural stone varies in colour, texture and size between units and between batches. Screens differ: reserve a sample, or see the bricks at the Richmond showroom, before you specify.
