Eco Acid

I have recently laid some concrete which will ultimately be an indoor storage area. The concrete had rain on it while still wet and the finished screed has an unstable surface as the surface cement has washed out. What do you think I should use to seal the concrete surface with so as to give a dust free, hard wearing finish?

Before sealing you need to make sure all the loose surface is removed, this can be done by either pressure washing (ideally with a flat surface attachment, grinding and washing or using the Eco acid (link below).

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.

I am in need of a non acid based mortar remover to apply to a newly laid black/blue limestone patio, is the Green klean industrial remover suitable??

If you are worried about damaging the stone I would probably suggest using the Ecoacid rather than the Green Klean, it will do the same job but it is not as aggressive as the Green Klean. (link below)
