Why is my concrete chipping/peeling?
Another cause of chipping/peeling is when the surface of the concrete dries faster than the layer underneath it during construction. This prevents the concrete from completely curing and results in a porous surface. When subjected to high use, stress, or freeze-thaw cycles, the surface peels.
Why does stamped concrete chip?

Is Chipping new concrete normal?
Spalling concrete is a common problem where part of the surface peels, breaks or chips away. Also known as scaling, it is the result of a weak surface that is susceptible to damage.
What causes chips in new concrete?
When the temperature drops below freezing, moisture in the concrete tends to expand, creating internal pressure. Over the course of a winter, or over the course of years, as the internal pressure rises and falls, it stresses the surface layer of the concrete, which leads to spalling.

Why does top layer of concrete flake?
Damage will show up when the concrete is exposed to ice or snow which then melts and penetrates into the concrete and freezes. Frozen water expands about 10%, pushing the thin, weak top layer upwards causing the layer to peel off (known as spalling).
Can you overwork concrete?
Never overwork or over finish the surface of any exposed concrete slab. This brings too much fine material to the surface, works out the designed air entrainment*, and will weaken the surface of the slab leaving the top of slab more vulnerable to freeze/thaw damage and sheet scaling*.
Can you smooth out concrete after it dries?
It is possible to smooth concrete after it dries, but in many cases, it requires a fresh layer of concrete over the top of the dried surface. This can allow you to keep the surface smooth and even, even though the concrete is completely dry.

Is there a sealer for concrete?
There are two main types of concrete sealers: film-forming sealers and penetrating sealers. Film-forming sealers include acrylics, epoxies, and urethanes that form a coating on the surface of the concrete. Film-forming sealers, especially acrylics, are more susceptible to wear and will need to be reapplied frequently.
What causes concrete scaling?
Concrete slabs exposed to freezing and thawing in the presence of moisture and/or deicing salts are susceptible to scaling. Most scaling is caused by: The use of non-air-entrained concrete or too little entrained air. Adequate air entrainment is necessary for protection against freezing and thawing damage.

How does freeze thaw cycling affect concrete?
Here’s how freeze-thaw cycling can impact you. If you have water in or around your concrete, that water can freeze as the area around the concrete freezes. When it freezes, it expands, thereby putting pressure on the concrete and chipping off pieces.
What to do if your concrete is spalling?

Detecting Concrete Pitting, Flaking, and Staining
As tough as concrete may seem, it does deteriorate over time. The erosion of concrete starts out small, but as the years go by, the damage becomes more significant, resulting in uneven, rough flooring. As the structure wastes away, the concrete becomes weaker. This allows moisture to seep through and affect the soil foundation underneath.
