Mapei Grout

[Minnie]

I have a 2KG bag of white grout. The packet says "whilst stirring with a low speed mechanical mixer" (that would be my arm then) pour into a clean, rust-free container, containing 0.40-0.46 litres of clean water"

Now I don't want to use all the grout now, and 0.40-0.46 seems a very exact measure.

I take it 1kg would mean 0.20-0.23 of water? Does it have to be that exact?

They obviously expect everyone to do all their grouting at once.

It also says to remove 2/3 of adhesive between the tiles. That's going to be fun with the mosaics.

minnie im going to give you my honest opinion on this,and that is i would advise you not to use mapei white grout,,all there other grouts have been great for me but the white does not come out a good clean white colour,,there has been a thread about this recently on the forum if you wish to go look it up.

i know you have asked tonnes of questions doing this project and would not like to see the end result ruined for you,my advice on this occasion is to buy a diff brand

oh dear, sorry I've not looked but problems with my modem so whilst I'm normally good at looking things up, haven't been able to for the past few months.

I'd already bought it from Tile Magic. They're not open again until 27th. Hope they won't be ****ed off with me returning it.

I'm even wondering whether to go for white as it will show up all my uneven grout lines :lol:

Different brand as in BAL? Will check later. Got to do tea and have a bath in a nice clean bathroom. :smilewinkgrin:

Grey?! :yikes::yikes::yikes:

I can vouch for it being grey :mad2:

Oh poor you. Was it on your bathroom you just completed?

yep

 

[Minnie]

yep

Did you have to rake it all out and start again then? What did you use?

I saw you mention something on the other thread but can't remember the name of it. It had a U in it I think!

I've left the walls, and I've now got a bottle of Mapei fuga fresco which is a colourant, so I'll just whiten the grout with that. But around the sink splashback I used a tub of ready mixed unibond grout from a diy shop

I didn't see the previous thread regarding "grey" white grout, but my experience has always been good with Mapei white grout.

If you follow the instructions on the bag for mixing and application then all should be fine IMO. The first time I used it, I did think it was grey'ish but once it had fully dried, it came up brilliant white :smilewinkgrin:.

You need to ensure that the grout joints are free of adhesive so that there is no contamination of the grout (& colour) as well as having an even channel to apply the grout into. If there is adhesive in the joint it will show proud of the grouting and therefore what does it matter what colour grout you use, it will always look patchy and rough.

What adhesive did you use and when did you finish sticking the tiles? You don't want to grout too soon and naff things up either.

Why the oops? Because you used ready-mixed grout?

I never knew there was ready-mixed grout. Wonder why they offered me the powdered stuff?

I used Mapei ready-mix and I've got mosaics and the adhesive went absolutely everywhere so there's absolutely no way my joints are going to be adhesive free.

As for an even channel, I assume you mean the grout lines?

erm, not a chance!

Minnie, you really need to rake out the excess adhesive as much as possible. If you don't, your grout will be uneven and dis-coloured.

the Mapei keracolor SF grout gives a better finnish than the ultra colour white but, it can only be used for joints up to 4mm
