Finishing work in a Nut-shell for Building Construction
Work in construction is a group of construction activities relating to the
exterior and interior finishing of buildings to enhance their service and
aesthetic qualities. In many cases, the overall quality of a building or
structure being put into service depends on the quality of its execution. The
main types of finishing work include facing, plastering, flooring, and
of cement plaster
thick smooth cement plaster of 6mm or 12mm is to be applied on the ceiling, the
walls, beams, column, drain, bends to all brick and RCC. Cement sand mortar is
used as plaster mix in ratios of one part cement and four parts of sand. Before plastering, the surface has to be cleaned
with a wire brush, there should be no oil or grease, etc. left on the surface.
On the RCC surface, hacking should be performed. Necessary staging should be erected for ease
of plaster application. If there exists any holes or depression on the surface,
then it should be filled with mortar mix. This should be made to ensure surface
flatness & levels. After plastering,
curing should continue for at least 7 days to protect the plastered surface.
- Application of MALA plaster
smooth cement MALA plaster is laid in two coats, that is, 1st layer is 12
millimetre with rough finishing, and 2nd layer is 6 millimetre thick with fine
sand. The first step is to wash the mortar joints and keep them wet for at least
6 hours before applying the plaster. Apply the first coat of plaster between
the spaces formed on the wall surface. Roughen the surfaces with wires, for
better bonding to the second coat. After the second coat, remove the scaffolding
step by step & fill the holes with a mortar. Liquid waterproofing admixture
of approved make should be added. Curing of plaster shall be carried out for at
least 7 days. The activities should be carried out for height up to 11 m as per
given technical specifications, instructed by Engineer in Charge.
of cement-based putty
layer of 1.5 millimetre of white cement-based putty is to be applied to the
full area of plaster in two coats. Cement putty is applied to fill uneven
surfaces and all pores of mortar or concrete wall. Before starting the
application of cement-based putty, the surface has to be watered properly.
After the first coat of white cement-based putty is dry, rub the surface gently
with a wet sponge to remove loose particles. The surface should be allowed to
dry for at least three hours and then apply the second coat. Leave the surface
to dry for a minimum of 10-12 hours, preferably overnight to make the surface
ready for the paint to be applied.
of emulsion paint
Premium Emulsion paint, of three or more coats of approved colour and shade, is
to be applied on a clean surface. First of all, prepare the surface by ensuring
it is clean and free from dust. One coat of primer is applied on the surface to
ensure that the finish will be streak-free before the application of the
emulsion paint. The surface should be allowed to dry for at least 48 hours. The
thinning of emulsion paint is done with water. The
emulsion paint is applied in the usual manner with a brush, spray, or roller.
The finishing surface should present a smooth finish.
of weatherproof exterior paint
or more coats of weatherproof exterior paint, of approved make and shade, is to
be applied. Before the paint is applied, the surface area must be clean and
free from dust and any other debris. As the exterior walls are exposed to
moisture, humidity, and water, make sure to get rid of all the accumulated dust
and dirt. A coat of primer should be applied on the dry surface before application
of the paint. The weatherproof paint gives good and even shades over the
plasterwork, brick surfaces at all levels.
of Texture Paint
paint with a finish is to be applied on the interior or exterior wall at all
levels of the approved sample. The holes and depression should be finished
properly with the mortar mix. Texture paint shall have a coat of sealer to
protect the surface from dust and moisture. As the texture paint is applied
directly to the bare drywall, the primer has to be applied on the leveled
surface. The adjoining surfaces shall be covered with drop cloths or with
plastic sheeting. Before applying the texture paint, patching should be done on
the wall. When the applied texture material has reached the desired
consistency, roll over the surface again, if required.
of Matt Finish
Two or more coats of Matt finish paint of approved make and shade is to applied. Matt finish PU Paint is provided to give good and even shade over the plasterwork and brick surfaces at all levels. The surface should be thoroughly cleaned and the surface should be allowed to dry. The surface should be rubbed with sandpaper for getting a smooth and even surface. A coat of primer is to be applied to provide a consistent base for topcoats of Matt Finish.
