done for all the joints. Finishing mortar joints in blockwork/masonry,
stone or brick is called pointing. Clean all the surfaces and joints of the
wall with a wire brush; there should be no lubricant, oil, etc., left on the
wall surface.If there are any holes or cavities on the surface, fill it in
advance with concrete and dry it for at least a day.
Plaster the entire
wall, wash the mortar joints and keep it wet for at least 6 hours before
applying cement plaster. Hacking must make on all concrete surfaces such
as columns, beams, ceilings, and retaining walls before plastering to ensure
proper bonding between mortar and surface. Confirm all the electrical

PLASTERING OF INTERNAL
WALLS:
In brick masonry or
blockwork, the consistency of plaster is generally 12 mm, and in the point of
concrete masonry or blockwork, this thickness varies from 9 to 15 mm.The
proportion of cement and sand for application varies from 1:3 to 1:6.Engineers
should closely observe the mortar mix ratio on-site. The only necessary
portion of dry mortar needs to be prepared. Use the trowel to apply plaster
between the spaces formed by the screeds on the wall surface. After levelling,
let the plaster set before curing.
External

PLASTERING OF EXTERNAL
WALL:
All the joints and
surfaces should be well cleaned with a wire brush and ensure they are free from
oil, grease, etc.Select the 24 gauges for exterior plaster and weakling mesh of
size 12 mm mesh.Cut the chicken mesh in a minimum of 20 cm to 23 cm in width
with a cutter.Fix the chicken mesh on the joint of R.C.C and masonry/blockwork
wall by plumbing nails on the R.C.C member and wire nails on the
masonry/blockwork member.The weakling mesh should be tight sufficiently in both
directions, vertical and horizontal.
To avoid buckling and
loosening of chicken mesh, which may come out of the plaster, the spacing of
nails should be less than 9" (23 cm). The external wall will align
and fix level pegs on outer wall surfaces using the surveying instrumentcenter
plumb bobs.After the levelling of walls is completed, the projected surface,
which is out of plaster due to an uneven surface, will be cleared. All the
openings, such as windows and doors, must be aligned for perpendicularity.
Dimensions must check for a clear opening to avoid gaps issued after
installations.
