Can you fix pitted concrete?
Smooth it out best you can with a putty knife or margin trowel. Within 24 hours the repair will be hard enough to grind or sand flush. For larger areas of pitting and spalling, we recommend using a 100% epoxy concrete patch with a sand aggregate. Once cured, these repairs are actually stronger than the concrete.
How do I stop my driveway from pitting?
Clean with a pressure washer. Apply a concrete resurfacing compound, mixing small batches, so you won’t have to throw away any unused or dried-out concrete. Pour the mixture into the holes and level off using your trowel.
Can a concrete driveway be resurfaced?
RE-CAP™ Concrete Resurfacer will renew your old, worn concrete driveways, sidewalks and patios at a fraction of the cost to tear out and replace old concrete slabs.
What does spalling concrete look like?
Spalling concrete can look like round or oval depressions along surfaces or joints. Spalling tends to be most common in cold climates when de-icing chemicals are applied or when seasonal freeze-thaw cycles damage the concrete.

Why do new driveways crumble?
Why a Cracked Driveway Leads to Crumbling Concrete Over Time
Too much water can wash away the soil supporting your concrete. Too little and it can cause the soil to shrink. And when water freezes and thaws over and over, it can cause the surface of your concrete driveway to crack, pit and crumble.
How long will concrete resurfacer last?
How long does it last? Thanks to its advanced bonding properties, concrete resurfacing can last for quite a while. A properly resurfaced floor can last from 8-15 years.
What is the best concrete resurfacer?

Should I pressure wash my driveway?
That is why most professionals agree that your driveway should be pressure washed at least once a year. This will keep the grime off the surface and you can keep washing it per your need and time over the year yourself, to keep it in the best shape.
Can you pour new concrete over old cracked concrete?
There are situations when pouring new concrete isn’t the most suitable option. For instance, surfaces with larger cracks, heaving or settling conditions, or where height cannot be raised, replacement is a better solution. However, in most cases, you can pour a new layer of concrete onto the existing one.
How do you bond new concrete to old concrete?
When using a liquid bonding agent, paint the bonder onto the existing concrete and allow it to dry until it is tacky. This usually takes only a few minutes. Then apply the repair material. Just as in the process described above, after the bonder has become tacky apply a scratch coat and then apply the repair material.
