What is neat cement?
Simply so, what is neat cement punning?
Punning, in my understanding, is a thin layer of mortar/plaster used on a wall to achieve a specific charcter of the surface, most common a flat one. Screed is a word with many applications all meaning to even a floor.
Considering this, what is grouting a well?
Grouting is the placement of a sealing material such as neat cement or bentonite into the annular space between a well casing and the borehole created during well construction. Grouting is an effective and necessary measure for the protection of public health and ground water quality.
Key Difference: Wall putty is used for purposes like leveling of wall surfaces, and being a protective base for expensive paints and many more. On the other hand, POP short for Plaster of Paris, is a white powder that is used for the outside layer of building and walls. Wall putty is based on cement or white powder.
