Best method to remove grout without damaging the tiles

[Bradma9]

Hi guys
iv got a big shower room in a golf club that needs re grouting as the white original 3mm grout isn't very white any more! Just wanted if there is a quicker method out there!
many thanks

ive heard but have not tested that the bosch multi tool takes a grout remover bit and its apparently fantastico lol

I used the hand held (slow method) grout rake and rake knife .
With precision the tiles will be safe

Yea tea bad iv got the bosch multi tool so gonna try that however I'm worried about not touching the tile.
i thought the grout rake is gonna be the best, I'm gonna have three people including me on it so hopefully it will go alright.

 

[Mr Tiler]

how big we talking here?

I'm not sure bud, just did a visual with the owner that I know, doing it for a membership so if we can't get it done quick it won't be worth it! But yea it's rather large. Ill post pics when I get them.

Tbh there only the standard white cheap general tiles but really don't have the time to waste re tiling!

 

[Mr Tiler]

having never done a re-grout how deep are you intending to go is it the depth of tile of a couple of mm in?

this would be the best method Grout Colorant great value and top quality from Tradetiler

That looks really good! Thanks for finding it!Have you used it before, just worried that the mold of the white grout iv got would work its way through that.

You will need to clean the joints first.

cheap white are generally ceramic... very easy to chip if not careful. Good luck, will be good to see a before & after pic

I have a bathroom to regrout for a mate. Tried the vitrex electric grout out tool...rubbish. Then went back to the old hand scraper...even worse. Would be easier to retile it. I dont normally do regrouting but thought as its a mate I would. Grout only been in a year but in the shower its started going mouldy, has cracks along edges and silicon is black. Rest of the room is good as new. No movement in tiles with cracks in grout. Told it was all tanked and tiles fixed with white cement adhesive. Must be something reacting in shower
