problem grouting

[charlie1]

hi guy's,

done a porcelain floor the other day. just had a call back saying the grout had dried different colours, black, grey, and white in places. i was using granfix flexi grey grout. I'm going out today to see but has anyone had this problem before?

What colour was the grout?

I tend to mix my grout every now and then as I have been told that with darker grouts the colour can drop to the bottom of the tub.

But if it's going from black to grey to white, that's a large colour change isn't it ?

Only things I could think of would be, was there any contamination in the grout bucket fom another job ? , was the grout thoroughly mixed first time round ? or was the floor adhesive dry enough or did you grout in the same day ?

 

[charlie1]

yes i grouted same day.

thanks for the advice, i am going to check the dammage and see what i can do to fix the problem. worst case scenario would be to re grout. Correct?

 

[Fekin]

Possibly, but there will be more people on here later that might have a better idea.

Another granfix grout problem....seems to be a few cropping up .....some grouts especially the coloured ones need to mixed well before commencing grouting.....dave..

I had it once. I was told it could have been the fact that the water to grout mix each time wasn't the same! I grout with Ardex only now.

I use granfix a lot and have not experienced any problems...maybe time for a change before I do..may try mapei..

 

[howard]

i use mapei all the time its the best ive used

I use bal or ardex, mix with a drill let stand for five minutes, and never had any problems.

hi all,

thanks for all the advice. Went out to see the floor and have decided to re grout. customer DID however exaggerate the extent of the problem.

grout had dried mainly Grey with patches of white so rip it up and start again!!

to be totally honest i'm just dying to get a shot of my fein multi master i just bought last week.

thanks again for all the advice.
