I have in my shed three lots unused "Mapei tile grout" from B and Q. Mis purchased.
I have always blamed myself for the wrong colour I bought..
Today I drive 16 miles and an hour trip to buy some more and come back with another wrong purchase!!
The colour is not stated anywhere that one can quickly ascertain ..except a very small print by the tiny bar code. The colour sample on the package was a completely non-discript fawn/beige/warm light- brown. And what is it really after a 16 mile trip?
Grey Grey grey. And wrong on my light brown tiles.
I feel this is actually very sharp practice and they well know they are misleading the public. Knowing that it is confusing.

Shabby.
