Re-doing grout joints

[tileman]

Hi, I have been offered a job today on a 15m2 kitchen floor to remove the grout and re-do in black, some tiles are lifting and need to be re-fixed but most of the floor is good, it's a hell of a job to remove all that grout.
I have seen on this forum something about grout colouring pens, any help welcome.

It's not a job I would ever like to take on as there is pleant of scope to damage tiles raking out the old grout and end up having to replace at own expense.

If I was to estimate on a regrout job I'd explain the problems and time scale not being a known factor and have to price big for it.

For a regrout you really need to remove as much old grout as possible for the new grout to get a good bond on the tile.

Don't know about grout colouring pens, but I can't see that they do a good job.

Arn't the Fein machines good at removing grout and the like, think they are about £160, possibly worth the investment for this and future jobs, know they do a multitude of other things too......everything but make the tea!!

I've done a fair few re-grouts with a fein,charge well for it and its very easy on floors. Would never do one without one though,very hard work.

How long do the blades last?

Thanks lads, Don't really fancy the job but I know the guy and he's ok, I was looking to save me effort and him money, Iv'e got a Fein Multi master, haven't had much use for it so far, carbide blades don't last long though and are expensive, I haven't used them on floor grout, so don't know what they will cost, the diamond blades are about £60.
The tools good but spares are over priced.

Only had mine 3 months but none of the blades are blunt yet and they've had plenty of use.

I know its fairly expensive but its the best piece of kit I have,I end up sorting out loads of problems on site for other trades that don't have a tool like this that sorts out unusual problems.

I have heard they are very good for regrouting, just got to be careful I guess.
