What are different types of plastering
According to a adhesive material there are four types of plastering :- 1) Lime plaster,2) cement plaster,3) clay plaster & 4) gypsum plaster
1) Lime plaster:- plaster in which lime is used as Adhesive or binding material for mortar
2) cement plaster:– plastic in which cement is used as Adhesive or binding material for mortar
3) clay plaster:- plaster in which clay is used as adhesive or binding material for mortar
4) gypsum plaster :- plaster in which gypsum material is used as adhesive or binding material for mortar.
According to type of wall, plastering is following types 1) external wall plastering, 2) internal wall plastering, 3) concrete wall plastering & 4) roof for ceiling plastering.
1) plastering of outer face or rough face of brickwork and concrete walls is known as external wall plastering.
2) plastering of inner face or plane face of brickwork and concrete walls is known as inner wall plastering.
3) plastering of concrete structure like column and beam is known as concrete wall plastering
4) plastering of bottom face of roof or ceiling is known as roof or ceiling plastering
Plaster cement sand ratio
Recommended cement sand ratio for plastering & plaster cement and sand mix ratio depends on type of plastering work. there are several types of cement sand mix ratio used for brick wall plastering, ratio of cement and sand for plastering depends on types of work and plastering types it is rough or plane surface.
Recommended plaster cement sand mix ratio for plastering of plane,rough surface of brick wall, concrete wall and ceiling are 1:6, 1:4, 1:5 & 1:3 are used respectively.
Plaster cement sand Ratio:
● 1:3 – External wall (in sever climate)
● 1:4 – External Wall (normal conditions)
● 1:4 – ceiling plastering
● 1:4 – concrete wall plastering
● 1:5 – internal plastering with coarse sand
● 1:6 – internal plastering with fine sand
Recommended cement and sand mix ratio for plaster
Recommended cement and sand mix ratio for plaster are following:-
● plaster cement sand ratio 1:3 are used for plastering of external wall prone to sever climatic condition and for repairing work. This ratio is not recommended for general use at construction site, but it can be used for waterproofing and binding
● 1:4 mix ratio of cement and sand are used for external brick wall plaster and ceiling plaster
● 1:5 mix ratio of cement and sand are used for internal brick wall plaster when fine sand is not available
● 1:6 mix ratio of cement and sand are used for internal wall plaster when fine sand is available.
● Ans. :- recommended plaster cement sand ratio are 1:3 (for repair),1:4 ( for external wall,ceiling, roof & concrete plaster), 1:5 ( internal brick wall plaster have no fine sand) & 1:6 (for internal brick wall plaster whick have fine sand) general used in civil engineering & building construction
