POWERPOINT PRESENTATION OF INTERNAL PLASTERING

1. ON

2. About plaster
• The word “PLASTER” comes from Greek
language meaning “to daub on”.
• In the past, plaster was based on lime, but
today it is also based on “gypsum” and
“cement”.
• Plaster is applied to wall or other surfaces as
a wet mixture of binding material (lime,
cement or gypsum), aggregate (usually sand)
and water.

3. •This is the process of covering rough surface
with a plastic material to obtain an even ,
smooth , regular , clean and durable surface.
On other hand we can say that :- A
mixture of lime or gypsum , sand and water
,sometimes with added fibers used for coating
of walls and ceiling.

4. The objective of plastering are
1. to conceal defective workmanship
2. to give smooth surface to avoid
catching of dust.
3. to give good look.
4. to protect the wall from rain water
and other atmospheric agencies.

Plastering

6. INTERNAL PLASTERING
Type of interior plastering are :-
 Lime Plaster
 Cement Plaster
 Lime and Cement Plaster (Stucco)

7.  Should be fire and sound
 Should provide a smooth ,non absorbent
and washable surface
 Should be weather proof
 Should be free from volumetric changes
while setting and drying
 It should adhere to the background
easily
 It should prevent penetration by moisture
 It should be cheap
