is it Ok to use wall tile grout on floor tiles?

[melspence]

Hi folks

new to all this diy stuff. We used proper floor tile adhesive to put down our ceramic floor tiles. however, would it be ok to use white wall tile grout for the spaces inbetween the tiles?

thanks

Often floor tile spacing is larger than that of wall tiles.
Wall tile grout can be designed for smaller spacing than that of the larger spacing in floor tiles.
So if you were to use this and you spacing between tiles is bigger than the wall tile grout can handle, it could shrink and crack.

It’s not just a question of tile spacing but that is important? What is the floor made of? What are the walls made of? Most importantly, exactly what brand & type is the adhesive you have?
