Yes, this will darken and revive the Fireplace, if cleaned with white spirit and wire wool beforehand to remove dirt & grime. Here is an example from one of our customers.
Is Slate Blacking waterproof?
Slate Black restorer is not recommended in an area that will get damp or wet as it will wear off over time. It is not really designed to get wet but many of our customers do buy and use this in areas that get damp. They just re-apply when the area starts to wear off. In areas that are not in a damp area we do always recommend to seal using a wax finish to protect but again this will not be waterproof.

How do you polish a slate clock case?
Have a look at this article we did with step by step instructions. It is easy to do and this method is used throughout the antique restoration trade with huge success.
Will the slate blacking make a grey hearth black? If yes will it be a matt or shiny finish?
As long as there is no existing finish on this the Slate blacking should work. As for the finish, the more coats you apply will result in a more shiny finish. After you apply, you can buff to achieve a higher shine or leave for a slightly duller finish. I would recommend trying this on a small inconspicuous area first to make sure you are happy with it.
