Vintage Brick Repair

P1100368Like most old houses, mine was in need of some repair. The bricks on the south wall had deteriorated over the years  and I even saw birds picking away at them.

You can also see some previous repair work with some modern bricks inserted.

Chauncey Builder’s Supply on Chauncey Ave. off of Kipling carries a PERFECT reproduction Ontario Orange Brick. Both size and colour are correct.

This brick has SKYCON imprinted on it and they cost $1.00 apiece.

P1110421As this is a soft clay brick, the real challenge with brick replacement and tuck pointing on an old house is finding the correct mortar mix to use.

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.

P1100369Bricks should be removed in small sections so as not to compromise the entire wall.

P1100377The new mortar is then tinted to match the existing colour. In this case I was more concerned with the structure over aesthetics as this wall is fairly hidden from general view.

The overall result was very good and I’ll probably do anther round when the weather gets better in the spring..

Please use this post only as a guide and consult with a knowledgeable contractor regarding the correct mortar mix and re pointing.
