What colour addy to use?

[Silver Birch]

Hi All
I have 3 floors to lay next week, first time using quartz!
1 white composite, 1 black composite, 1 black quartz.
2 on hardi overlaid on chipboard 1 on concrete.
going to use 2 part flexi, any suggestions which?
should I use white addy to avoid staining on tiles or will this show through the black ones????
any advice really appreciated.
Cheers

white addy for the white tiles, any ufh going down

easy way to make your mind up on this is hold the tiles up to a light. with some quarts tiles you can see light through the tiles. if you can see light you will be able to see the adhesive through the tiles same applies for marbles and stone
so with white quarts white addy. to stop your trowel lines showing butter the back of the tile then lay in addy . there are some cheap quarts out there that are no good if you have ufh they tend to curl good luck
