How common is air gap in plastering

[krishnakumar]

It has been almost a year after my house construction and now I can see very thin air cracks in the wall and near the joints of compound walls. The cracks hair like in width but have a fairly good length.
I confirmed that there is no crack in the wall itself and that no hollowness. You need to look carefully to spot the cracks but still my question is how common are such air cracks \ air gaps in construction?

quite common.. next time when you are getting a patti done.. ensure that it dries up completely and nicely done by a experienced team..
