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 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).
Once you have got the surface prepped you can then seal it, I would recommend our Super Plus sealer (link below).
