Black tiles on shop front.

[Bert]

Hello to all & Happy Holidays,

Any and all advice appreciated.

With the black tiles likely to attract more heat are there any preferred adhesives or other issues to consider.
Does the type of grout matter. customer prefers grey.
Shop front is already tiled and customer is reluctant to remove existing tile to keep costs down.

Thanks to all.
