Replacing a Brick

•You can get the brick out whole by using this method.
Get a plugging chisel and chip away at the mortar around the brick, if the mortar is old and crumbley it wont take long, if on the other hand the mortar is hard it may take hours.

•If you dont need to save the brick.
Just go for the kill and smash the brick with a hammer, then remove the rest of the brick with the pluging chisel.
Or get a cheap Rotory Hammer drill, they cost about AU$70.

Make sure all the old mortar and brick is removed before you even think about putting the replacement brick in.
Even the smallest piece of old brick or mortar will cause you trouble if you leave it in.

•Make up a small amount of mortar, you can mix this in a bucket with a trowel.
Make the mortar to the ratio of 6 sand, 1 cement, and some lime if you have any, the absence of lime wont be that important for just one brick.
Or you can use premixed bagged mortar, just add water.

Get a small trowel of mortar and put it in the hole as the bed joint.
On double skin brickwork if you put too much mortar in you wont be able to get the new brick all the way back as far as it should go, as the mortar builds up behind the brick as you push it back.

Butter both ends of the brick. Have a look here.

Turn your trowel over so the handle is underneath as in picture 4, sit the brick on the trowel and insert into the hole, now slide the brick off the trowel.
Make sure the brick is level and flush with the other bricks.

Get a Dutch Jointer or even the plugging chisel ,and use it to ram some mortar into the top bed of the brick.
Finish it off so the brick blends in with the others around it.

You may then have to wash the repaired area with acid to clean it.
