COMMERCIAL BRICK WORK
Abbey has had the privilege of working on some of the classic brick and stone buildings in Southern Ontario. A few of these were completely built with Lime putty. Visually, you can identify these by the thin (penny farthing)joints. As lime putty was slow to firm up, masons would mix clay dust or fire ash to help the putty set. White Portland cement was introduced around 1880 and while it set faster, it did not negatively impacked the lime mix. It was still breathable and flexible.
When building a wall, whether brick, stone, or block, the mortar must be weaker than the building unit. If there is any movement, the mortar will give, not the building unit.
Abbey uses a mix by volume for Heritage wall building: 1 1/2 slaked lime, 1/2 White Portland, and 6 course wash sand.
For outside finishes and pointing, we use a little stronger mix, which will stand up to the elements but is still breathable: 1 slaked lime, 1 white Portland, and 6 course wash sand. Pigment may be added
