Peel means surface damages at bedding/finished surface.

I think it is called raking process which is done before plastering. For better cohession. Raking done for about to 20mm depth by means of cheisel and hammer on the surface before plastering and the apply water on the rough surface and start plastering.

1) Dubbing: The process of filling the voids in the surface to be plastered.

2) Hacking: The process of making the background rough, before plastering.

3) Peeling: Small loose masses are formed on plastered surfaces due to failure of bonding between the coats, known as peeling.

4) Blistering: Formation of small patches of plaster, swelling out beyond the plastered surface,

Peeling and Blistering are defects in plastering, and hacking and dubbing are techniques used in plastering.

Thanks everyone for explaining.

Hacking refers striking of surfaces such as RCC walls, columns, beams, slabs etc. , with a chisel to dent the surface in order to create a proper mechanical bond between structure and plaster.
