how long do you wait to put a sealer on new concrete
If you poured your concrete in the middle of dry summer then 14 days should be the minimum amount of time you should wait. After you seal the concrete (depends on conditions and sealer product) you will typically want to give the sealer 1 day prior to walking on it and 48 hours after application before driving on it.Again depends on type of sealer (ie. epoxy...). concretenetwork.com has a lot of good info as well.onfidence votes 142. Typical concrete takes 28 days (4 weeks) to cure. Prior to the 28 days concrete still has moisture in it that weakens the strength of the concrete. If you seal it prior to 28 days there is a chance you will be sealing in some of that moisture and hence weakening the integrity of the concrete.
