Replacing spalled brick, tools and avoiding cavity filling

[camerart]

Hi,
Are there any special tools for replacing spalled bricks, especially, to avoid filling the cavity.
Cheers, Camerart

Hammer.

Chisel.

Drill a series of holes, around the mortar first, to try to release the brick whole.

Duck tape to cover surrounding bricks and replacement brick. Really keeps bricks clean.
Never had a problem and easy job. This took 2 hours but I don't have a picture with duck tape over bricks. Wedged bricks to pack in correct position.
I drilled around bricks to loosen.
Pull duck tape when its all set.

Buy yourself a nice masonry blade for your reciprocating saw, drill a few holes to get the blade in and just cut around - it won't cut brick but it'll go through the mortar easily enough. For replacing bricks I always shove some cavity insulation in first to stop the mortar spilling out the back.

Hi Al,
Not sure about the chisel!

I like the idea of a masonry saw.

One thing I noticed, while reading a bit about this. The mortar in my house has lime in it, and it's been pointed with no lime mortar, which may have caused the spalling.
Thanks, C

Hi,
Good tip about the insulation

I've been looking at saws, some reciprocating out/in and some horizonrally, also for horizontal cutting wheels.

Has anyone used the arbortech ones? or ones with a triangle shaped saw?

I second the recip saw. With the right blade, works a treat.

Hi J,
That's good, as I can use it for general sawing too.

Hi,
I had a quick look at saws in B and Q, but none of them mentioned masonary, only plastic, steel and wood.
Can anyone suggest a resonably priced one please? (it won't have much use)

Hi J,
It looks quality!
Will it fit any of the reciprocating saws? I see one the same site, £60 to £360. As I won't be using it much I would buy the one of lower end ones, is this ok? I understand get quality tools, but not for for this purpose.

For a one off job, get the cheapest - or at least cheaper end. Check the saw to be 100% sure but I think all the blades will fit all the saws.

Hi J,
I bought the Bosch saw suggested, only to find that it isn't suitable for 9" solid walls.
