When new concrete is placed, it will often have a high water-to-cement ratio.
If the water-to-cement ratio is too high, or if there are voids in the concrete, air bubbles can become trapped.
When these air bubbles rise to the surface of the self-leveling compound they cause indentations or pinholes.
This usually happens when the temperature outside is warm and humid, as this causes the compound to dry out too quickly and not gives it enough time to properly cure.
