I agree with you on most of what you said especially the colour range, not sure why i had so much trouble with it, i mixed it according to its instructions but found that it dried patchy and on a timber floor it actually cracked!!! This has never happened with bal (any colour) on any surface. When i phoned mapei up to ask why this keeps happening they said it must be the way i mixed it (mmm wonder how much grout i have mixed up over the years) i explained that i had mixed exactly to how the instructions had advised but still it dried patchy! they then explained that it must be something to do with the water or maybe a bit of my sweat had fallen in the bucket lol they also said that you have to mix enough grout for the entire area to be covered with one mix! i wonder how you could do that on a floor that's 88m2, even if you could mix enough grout to cover that area i doubt very much that any of us on here could grout up an area that size using once mix before it started going off in the bucket.

I'm not trying say your wrong mate but would love to know why this has happened so often and to quiet a fair few tilers, like i said before it has happened to wivers too and i find it hard to accept it's down to both of us being incompatent grout mixers.

any pointers on possible reasons why or tips on how you mix it would be appreciated cos they do have a cracking colour range and i would love to use it, but at the mo my trust in the product has gone.

Thanks mate

TJ

with that many complaints seems like there is only one thing in common that could be at fault

You ever used it Jay?

TJ

no i havent so i cant judge the product just reading between the lines you cant all be wrong

did think it was me at first but when Wivers phoned me up saying that it had dried patchy on his bathroom walls i knew we both couldn't have mixed it up wrong.

Anyone else on her had problems with this

TJ

TJ quick quiz 1 grout all from same bag .2 mechanically mixed at slow speed .3 wait 5 to 10 minutes re stir to consistancy of toothpaste .4 dampen joints (if tiles draw moisture) .5 apply and wait to firm in joints. 6 wash of using minimal water .7 polish off .8 silicone if you do all of the above its not your problem

Case closed then, cheers Jay

TJ

you shouldnt really polish tiles until the grout is cured as rubbing the dry dust into the wet grout can cause discolouration..

cheers Andy but i think that pretty much goes without saying.

Have you used Mapei mate?

TJ

Mapei ultracolour rules

As long as you make sure you get the ratio consistent of course

Lol but thats the trouble you see bighen it patched even though it was all from the same mix!

TJ

Hi TJ.
Helps now I've read your previous post

I always with Mapei mix either 1/2 or full bags depending on area, tile size etc to the water ratio.

I always wait the same amount of time before I wipe with the washboy, and use the same washing routine everytime.

To date, even on large areas I haven't had a problem - not telling you how to suck eggs etc.

My supplier read me the riot act 1st time I'd bought it and gave me the fear of God!

Must have worked though lol

Thanks mate, it's so strange cas a few people i know say they have nothing but trouble with it and would never use it and a few others like yourself really like it. Maybe i'll try it again cos i don't have a problem with their adhesive or silicone or primer G itand would like to use this stuff cos the colour range is so goiod and the price ain't bad either.

Just a thought but when i mix up grout i do it by hand and with a rubber/surgical glove on, i wonder if the powder coating on the glove has an effect, maybe next time i should try it with a low speed mixer.

What you reckon
