problem removing render

[emptybucketman]

I'm trying to remove the render from an 1930's Art Deco bathroom. The bathroom is tiled halfway up the wall and thus there is a step on the wall. When I remove the tiles there is about a 25mm thick layer of mortar that is very difficult to dislodge from the brick without loosening the bricks. The chisel and club hammer seems to just damage the brickwork. Any ideas on a better way to remove the render and thus the step?

If your bricks are that loose I'd be looking at fixing them.

How about the old Ozito hammerdrill from bunnies $69.00 from memory, ask Al. see if you can get a scutch comb attachment
Failing that a big angle grinder and lots of dust.

Yep, Id go the Ozito, but they have risen in price to $99.

As Bleeding has said, if the bricks are that loose, they need looking at.

Thanks for the info. I'll chase down the hammer drill/scutch attachment option.

It's not that the bricks are loose but the cement substrate for the tiles is very tough (high cement/low sand content) and the brick mortar appears to be a lime base.

Kennards Hire has an handheld concrete mower with an industrial vac attachment to minimise the dust. Any thoughts.

Couple of weeks ago Aldi were selling what looked suspiciously like a rip-off of the Ozito for $49.95, might pay to look in a couple of Aldis to see if they still have one kicking around.

I persisted with the chisel and club hammer and it paid off. The loose bricks were located around an inset soap dish and an old pipe chase.

Yep persistence will do it, so people tell me.
