How long do you have to wait to seal concrete? You have to wait 2-28 days to seal concrete depending on the type of concrete sealer used. If the concrete is new and hasn’t had 28 days to cure, then you want to use a cure and seal, or a sealer rated for new concrete. If the concrete has had 28 days to cure, you are free to use any concrete sealer you want.
Sealing Concrete Less Than 28 Days Old
It takes 28 days for concrete to full cure, assuming the concrete was properly mixed and poured. If you want to seal concrete less than 28 days old then you need to use a concrete cure and seal, or a concrete sealer rated for uncured concrete. There is a difference between the two:
- Concrete Cure and Seal: Concrete cure and seals help the concrete to properly cure. They can be applied as soon as 24 hours after the concrete has been poured and are ASTM tested and approved. Review our selection of the Best Concrete Cure and Seals.
- Concrete Sealer for New Concrete: There are concrete sealers that can be used on new concrete, but they aren’t rated or approved as cure and seals. They will seal the concrete, but they won’t help in ensuring that the concrete properly cures.
