Stain Concrete bathroom floor

We are renovating our bathroom and would like our existing concrete floors stained to a dark grey. We are not wanting it to be prepped to a perfect condition as we are going for an industrial look, but there are some possible grinding as there is a bit of glue residue and rough patches here and there, there is a crack also but would like that to stay. This is also a bare floor...bath, toilet and any other restrictions have been taken out already The area is about 2.5 m by 1.4 metres. Photos of the floor as well as the look we are going for attached.
