This question was asked by

I would appreciate any expert information you could provide to me, including indication of your recommended products, for preparation of green and mature concrete for colouring or staining.
I wish to carry out a DIY project.

The easiest way to profile any concrete, new or old, is to profile it using the Eco acid (link below) you apply this to the surface, agitate, leave for 5-10 mins and rinse off, once dry, pour a small amount of water onto the surface, if it soaks in quickly you are ok to stain, if it takes a long time to soak in you will need to repeat the process.
