I use one of these. Dave at tradetiler sells them also a Dewalt version. Excellent for grout removal.

Re-grouted 3000m2 using a dewalt cordless circular saw with a diamond wheel an big vac attatched 2 the saw had 2 buy a spindel adapter £20 for the saw then stanley the edges also 600x6oo porcelain night shift house of frasers between 3 of us we were doing 150m2 easy no dust minimal mess

what grout are you planning on using to re grout this with,and are you having to supply it?

im not sure this will work if you have used non flexi adheive however try bal non flex grout with gt1 admix might be strong enought o save your bacon as long as the tiles are not loose

 

[Gall.B]

Agree with above bal wj with a gt1 admix doesnt get any stronger than that

We are using mapei with an aditve. Have done 100 meters in 2 nights using angl grinder and wet sponge and the grout has held no cracking.The tiles arent loose it is the floor underneath which the client was also told before the start of the job but said to get on with it because they didnt want another week adding on the job. Yes we are suplying the grout but hasnt used much being 2ml joints. Have used the bal with gt1 admix before i should have thought of using that. Just have to see if this works.

 

[alexc1989]

Why did you have to re-grout? 3000 meters is a lot of work!

 

[Gall.B]

had to regrout it twice m8, we were subd 2 a german firm the adhesive was 2 part flex onto ditra matt the grout on the job was in german but we recognised it as sontex kitchen grout unbloody real but told 2 carry on the grout turned to dust as predicted, easy enough to remove. Next up was mapei silver grey to light for a heavy trafficed floor & it struggled 2 cope with movement in some places so as the floor space ran over 3 buildings up 2 300 years old lastly it was done in bal with admix, then same again in the dublin store. This is what happens when flooring companys take on big ceramic work.

Hope u got paid for that! Makes me feel better that this is only 125m2 but dont fancy doing it again if this mapei doesnt work.

 

[advancetiling]

Just out of interest,how come you went with 2mm joints and not the recommended 3mm(less grout to use?)

 

[Gall.B]

Hope u got paid for that! Makes me feel better that this is only 125m2 but dont fancy doing it again if this mapei doesnt work.

Yeah got paid no probs was between the client & the flooring company we were subd to frasers paid for the second re grout was told it cost 20,000 in total between security leccy materials and wages

you should be fine with the admix bud.

At last a post I can reply too!!

I'm not a tiler or a builder or anything like that but my advice would be to to invest in a tool called the Exakt Saw (I have the EC320 model which is the brownish colour casing, this one has been improved over the others, which why its sligtly more expensive).


I used this tool last night to channel out a wall for cabling and had the minimalist amount of dust to clean up afterwards thanks to the extractor connection and didn't even need to wear a mask!

Hope this helps
Simon.

if you didn't supply the materials you cant be responsible for them but if you fixed to a floor that was not suitable to receive tiles you have a problem what was the timber and how was it fixed ?

flexi adhesive and grout everytime , gives you piece of mind
