It’s important that the mortar is softer than the bricks. The mortar is designed to fail before the bricks do. Using modern Portland cement is a BIG mistake as it is TOO strong and the natural expansion and contraction of the structure will cause the bricks to break first.
For well over 30 years it has been common practice to prescribe the use of a Type-O masonry mortar for use on the conservation of masonry buildings. The most common formula of a Type-O mortar is 1:2:9, a blend of 1 part white Portland cement, 2 parts Type-S hydrated lime (most often dolomitic lime) and 9 parts sand by volume.
This is a simple ratio. I made up the mortar in small batches using an old Pyrex coffee cup as my measure.
2 cups of cement, 4 cups lime and 18 cups of sand. Water was then added at about 3-4 cups depending on the humidity and thoroughly mixed until it was the right consistency.
So, when talking to a contractor re: brick repair make sure he is aware of the need for a softer mortar on an old house.
