Hi,
We are going to repoint our 125-year-old masonry house (red brick with calcium mortar).
We have found a tool on the Internet that apparently removed the dust simultaneously with removal of the mortar – images can be seen on www.turptech.dk.
Before ordering we would like to ask is anyone can refer to UK or US literature on this – or general experiences?
best regards
Carsten Lund

I can't get to the domain you mention, but the danger with any tool for removing mortar is that it may remove some of the brick as well. If you are re-pointing with lime mortar (and I hope you are on a lime-built house) then you need to get the brickwork pretty wet, and keep it damp while the mortar sets. Power washing the brickwork is usually enough to remove any loose mortar and grunge, and wets the bricks at the same time.

It's another of those "let's fix the wife's hoover to the nangle grinder" ideas that we've all come up with after a couple of pints!
<span style='font-size:9pt;line-height:100%'>(Sounds a bit blokey and patronising that, but I think most men will adnmit that, while they may do their full share, and more, of the domestic hoovering, actual custody of said implement rests, well and truly, with the distaff side of the relationship.)</span> :;):
These yokes work, after a fashion, but the keys to success are having a decent hoover at the sucking end, and a close-fitting sole plate at the business end, otherwise, the EE-NOR-MOUS quantities of dust generated by the nangle grinder either doesn't get sucked away at all or some of it escapes through the sole plate before it can be draughted away.
However, I'm with Jon on this - using a nangle grinder at all on lime mortar is a crime against masonry. A stick with a nail through it is ample to remove a lime mortar, and the sheer bite and thrust of yer average nangle grinder with mortar-raking blade is way too destructive. These tools are intended for use with cement-based mortars, which are ridiculously hard.
The reason Jon couldn't get to the website is probbly because he's copied in the trailing full stop at the end of the sentence. The correct url is....

I typed the site name in, and it still didn't work, but your link seems to.
I like the caption "Repointing with a vacuum cleaner" - presumably you put it on "blow" rather than "suck"?
Reminds me of the time I found loads of woodworm infested sawdust used as soundproofing under the floor. The firm I worked for at the time gave us a Hoover Dustette for getting muck out of things, but it wasn't at all happy handling sawdust, as in that design the dust actually goes through the fan before hitting the bag. Made a lovely noise though!
