mapei ultracolor plus - TilersForums.com

Iv'e bought some Mapei ultracolour for a wetroom, I usually use Dunlop or bal and just add water whilst mixing by hand to my desired consistency, I am taking it for granted that this method is also ok with the Mapei or is the method different for this type of grout?

If it is Ultracolor Plus then you need to follow the instructions on the bag carefully. It is a fast setting grout whcih gives excellent results if used correctly.

I meant add grout to water in my earlier reply, read the instructions for the Mapei grout and it says to mix the whole box to a certain measurment of water with a mechanical mixer, glad this post came up, because I would have overlooked this, will be grouting towards next weekend.

Grouted with the mapei today, found I had to put a little more water than the reccomended 1 litre in the instructions as it was totaly unworkable at that consistency, only about 100ml though, good product, easier to work with than bal flexible which I find goes everywhere but where you want it on the wall. Lol

used ultracolour plus down at westfeild and had a few early problems with it but as the other guys have said

mix with whisk
leave to stand remix after 3 min
work small area at a time
beware of other factors that alter setting time ie tile type, heat,etc..
clean cold water with spongne/ washboy to wash off
change water often and clean out water bucket and spongne

Have had the same problem mate
I have previously always used mapei grout ( still trust their adhesive )
LAST YEAR : used beige on a customers bathroom, followed mixing instructions to letter ( was very experienced with the make ) : colour a lot darker than sample.

So spent four days with a fein taking out all grout at my own cost ( because customer was not happy with it ) RE - grouted in PCI Bahama Beige ( customer choice )

Have had many similar problems with all Mapei colours except for white

Steer clear

Oh Leatherface what a bummer, I have only done one regrout with a fein, ended up like a flour grader, refuse point blank to do any regrouting, horrible messy job.

this re-grout was at my cost, because grout did not match colour sample
Customer was really being a pain, but because colour was not same I removed old and re-grouted.
I lost a lot of money on job and only just broke even.
have switched to granfix grout now. Still use mapei adhesives

I followed water and mixing instructions to the letter
