Who mixes grout colours

[Mr Tiler]

Why dye grey adhesive black?
is this in case any squeezes through joint and you don't have to clean out if using black grout.

when working with such a large area of mosaic tiles shading is pretty obvious under the tile so has to be a close match to both tile and grout I would imagine?

Well we inherited the job and most materials the first lot of adhesive was white and where the guy had started he had left squeeze through, which we had to grind-out so i thought i would give it a go and when we fixed it just looked better...........

No T you are wright as well black glass is still see through, and a black backing helps mate :hurray:

 

[Mr Tiler]

wheeeeeeyyyyyyy!!!

May have to try that dye sometime myself, a black addy with black glass mosaics would make life alot easier, as the tiniest bit of white addy can stand out against black grout.
But I suppose if theres any adhesive in the joints the adhesive and grout would have to match otherwise it'd look patchy?

Ive never had a problem with mixing grout colours, of the same make of course.

ok thanks for this info. i actually think that pool /glass mosaic specialists get in to this more than other fixers.
i did a job last year which was in a church where i was fixing all the stone and had more than enough to do without getting involved with two large mosaic feature walls.
i recommended a friend tom smith son of gordon smith and he always mixes his own colours for approval. cant remember name of colour pigments he uses but it made a huge difference to overall look and he will do this as matter of course for every job. i believe pigments very expensive but well worth the extra .
this is not the same gordon smith that i think you may be thinking of Dpf.

Mapei seem unable to get a consistent colour even from one bag, never mind mixing bags!

Well in truth I think the tech guy from mapei was nervous because he had probably only learnt from a tech sheet plus fact that it is true with mapei more than ardex that you are supposed to mix the whole bag and use as one as they see it mainly because they have colour pigments that can get to bottom of bag although I have only ever seen this in jasmin which I personally would never use .
I personally see no reason why if bag mixed well dry before adding to another grout similarily mixed there should be problem.all said the jasmine grout I would never as the colour when wet after curing if you have had a shower is dreadful.
