Re-doing grout joints - TilersForums.co.uk | Tile Forums

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?

Need to get a Fein thingy

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.
