Sealant and concrete

[biggles]

Have just poured a concrete slab and want to install concrete panels onto it and seal them , how long does the concrete need to cure for before the sealant will work correctly? Cheers

You want to give it 2 weeks before doing anything on it to let the concrete go off, some big companies insist waiting a month. So I’d say anything in that time frame

7 days before the chemicals have gone off I the concrete, no more reaction and no green appearance

28 days+ before I'd put a hiab lorry over it with a load of panels on the back

It won’t be driven on for a long time, just want to stand the panels in between the stanctions and seal them, this can be done from the un concreted area, the new pad will only be taking the weight of the panels, cheers

With most sealants you will need to wait 21-28 days for moisture to evaporate out of concrete. That’s based on 6 inch slab.
