How to Care for New Concrete
The first month — and the first winter — decide how long your new concrete lasts. A little care now prevents the damage that’s hard to undo later.

Cure it, seal it, and keep salt off it
Keep off new concrete for a day, keep vehicles off for a week, wait a month for heavy loads, seal it before its first winter, and never use de-icing salt on it the first year. Those five habits cover almost everything that goes wrong with new concrete.
Caring for concrete, step by step
Help it cure slowly
Concrete gains strength through a chemical reaction that needs moisture — it isn’t just drying out. In hot or windy weather, the surface can dry too fast and cure weaker, so keeping it lightly damp for the first several days actually makes it stronger. We’ll tell you whether your pour needs it based on the weather the day it goes down.
The salt rule
This is the big one: no de-icing salt on concrete in its first winter. Fresh concrete is still at its most vulnerable, and de-icers drive water into the surface and force extra freeze-thaw cycles right at the top — which causes spalling and flaking. Use sand for traction instead, and seal the concrete before winter to add a layer of protection. After the first year, a good sealer and sensible salt use keep it safe.

Should I seal new concrete?
Yes — sealing protects the surface from water, salt, and stains, and it’s especially important before the first winter. Most concrete should be sealed once it has cured, then resealed every few years.
Can I use salt on my new concrete driveway?
Not in the first winter. De-icing salt drives extra freeze-thaw into fresh concrete and causes spalling and flaking. Use sand for traction instead, and be sparing with de-icers even after the first year.
How do I keep new concrete from cracking as it cures?
Keep it lightly damp in hot or windy weather so it doesn’t dry too fast, avoid heavy loads for the first month, and make sure it has proper control joints. Slow, moist curing produces the strongest surface.
How long until new concrete is fully cured?
It reaches most of its strength in the first week and its full rated strength at about 28 days. Treat it gently through that first month and it will serve you for decades.
