We have a tiled floor but they are old and don't look very good. We are thinking of going polished concrete but how do we get all the glue off and do we have to pour new concrete on top of the mess that will be underneath the tiles?

Usually this is not required, once the tiles have been removed the remaining glue and mess can be ground to a brand new surface. However there can be exceptions.

When do you add the colour?

Colours are added by the concrete supplier and are in the mix before the concrete sets.

What exactly is a warehouse finish and can it be used in a home?

The warehouse finish is typically used for any pre-existing or "old" slab.

What is grouting?

All concrete naturally has holes that can also be heightened in the grinding process. Not all floors require grouting. It is the client’s decision as to which “look” they desire and if a smoother look is required, grouting takes place to even up the floor.

What about aggregates in concrete mix? What is generally available and what is recommended?

This is an endless choice that is only limited by your imagination. There are numerous mixes available though your concrete supplier but it must be though out well before the pour takes place.
