wall tiles - do I seal the tops and sides?

[DrGonzo]

Put some wall tiles on with adhesive yesterday. Planning to put grout on tonight (it will have been 24hours for them to dry by then).

1/
The tiles come into contact with the work surface and on the ends they are open to the wall.
Do I grout the bottom part, tops and sides that are open or should these be sealed with some type of sealant/Mastik ?

2/
They are satin tiles and the adhesive I have says it can't be used as grout on satin tiles. Any idea why? I have a separate grout to use but would rather use the pot of adhesive/grout if possible...

Always use a powdered grout - don't use pre-mixed.
