This civil engineering article focuses on the method of Plaster and vital steps involved in plastering work. Plastering is the method of wrapping the blocks walls and ceiling with a smooth finish with different plaster materials (a blend of Cement and sand with a specific ratio 1:1/5,1:2,1:3 etc. according to the work requirements).
ALSO : CAUSES OF PLASTERING DEFECTS AND PROPER REMEDIES Pre-plaster inspection phases: •
Initially, verify all the dimension(Sizes) of rooms
•
Verify Angle/Diagonal of rooms
•
Verify opening size of Doors & windows
•
Examine the verticality of Brick or Block wall
•
Ensure that all MEP services (Mechanical, Electrical & Plumbing work) is set up.
•
Ensure that all MEP services are covered with wire mesh.
•
Ensure that corner beads are installed
•
Verify that plastering mesh is set up among concrete & masonry surface.
•
Dust & other lose material are detached and cleansed
• Now check that point is fixed on each wall that is a reference for plastering level & thickness of plaster, the distance & the guide points are based on the aluminum straight edge length. • A rush coat should be provided on the wall surface. The plaster work of the surface should be accomplished after drying the surface. • Plastering work should be performed on the basis of the specifications like lime finish, trowel finish, sponge finish, rough plaster and zone of application specified by the architects. • The thickness of plaster should not surpass 15mm. If necessary, the plastering should be performed in 2 coats. The first layer used should be cured for a day prior to deploy the following coats. • All surfaces in concrete should be hacked/Chipped prior to plastering with the purpose of providing a good bonding among plaster and concrete. The following points should be taken into consideration during Plastering: • All surfaces prepared for plastering should be soaked to get rid of absorption of water from plaster.
