Mapei Ultracolour Plus

[macten]

To me the problem lies with Mapei ultracolour white grout. Used to be a brilliant white a year ago now it mixes like a mushroom grey colour. I use UC for all my jobs and have enough experience to mix by eye and all their other colours are great and it's a lovely grout to use.
When I had a problem with the white I mixed some up back at home with scales and a measuring jug, brand new bucket and clean bucket trowel. Let it sit for 3 mins whilst the polymers 'wetted out' and remixed.
At no point did the mixture look white - and sure enough it dried the same crappy colour.
Will continue to use UC grout because I think it's the best but I will never touch their so called white again.

In the instructions you will need between 1.1 and 1.3 ltrs of water to a 5kg bag..And a mixer is required and not by hand..

I found this and rang mapei, after regrouting in bal, and they told me where I had gone wrong

I mix grout to the consistancy I like you cant do that with mapei you have to measure with a measuring jug

I tried this at home and it came up white

mapei sell a measuring jug with it all marked on but I use a cheap kitchen one

Dilema!
Have used Ultra Colour many times though not white and found it great.
Have a large white bathroom to grout on Saturday using white ultra colour grout which i've bought.
Do i take the risk?
I mix there grouts exact so will be peeved in the least if have any problems after reading folks experiences.
Doing a white grout i expect it to be white

let us know how you get on if you choose to use it mate,i mixed it to the tee and still found it off white

 

[kaharrison9]

Not worth risk K55.
Having had trouble a while ago with Bals colour range-limestone,brown,charcoal and switching to U/C and it's been superb.
Don't fancy going down the route of chancing this saturday with Mapei white and risking 10 days work.
Would be worth input from Mapei having read the earlier threads

fair doos mate,most of the grouts i use are mapei but i dont use white anymore for the reasons you just said i dont want to re do a bathroom due to grout,,i use pci or bal white now

 

[kaharrison9]

The only colour i had no trouble with Bal was there white i think it was the microflex though if i remember it seemed to dry quick on the tile face.
Is a true white though.
Not used PCI

I've never had an issue with Mapei U/C white or Ardex FS brill white, for that matter. I have to confess that I usually mix by eye as I feel confident in what consistency needs to be achieved. I guess I've just been lucky and will pay much more attention to mixing ratios in the future.
