Brick cleaning grinding disc?

[hoicem]

Just watched one of those challenge Tommy Walsh programmes on Discovery Real Time. He needed to clean some old bricks of paint and used a large grinder that had a disc with ribs/grooves on the face which ran over the face of the bricks and cleaned them. Looked great, anyone know where to buy such a disc?

[Stuart Noble]

Probably a flap disc

[sm_jamieson]

Not one of these ?

[hoicem]

Nope, it looked like an ordinary masonry cutting disc except the face of it had diagnol ribs going across it.

[Pete C]

Was it like this?

Was it dished with a depressed centre?

cheers, Pete.

I think this might have been it:

the same, although his was bigger

*Everyone's* looks bigger. It's just the direction you're looking at it from. ;-)

Should only be looking at the wall!

Grinding discs are a great way to ruin brickwork. Paint gets in the pores, and at 11,000 rpm a grinder disc of any kind is far too fast to get into the pores, unless it just rips them off. Totally the wrong approach imho.
