Abstract The construction industry has a long Turn Around Time (TAT) due to human- based work environment. Further,
lack of skilled labour, increase in labour cost, and technological advances are forcing rapid changes in building construction,
which mainly consists of commercial infrastructure and residential building, where plastering work is must. The introduction
of a new automated plastering machine can help to reduce the TAT in the construction field. The present work developed a
model of a wall plastering machine. The proposed machine consists of an AC motor, gear box, wire rope mechanism, pulley,
hopper-tray, guide ways, etc. The model has been fabricated considering a normal constructed brick wall, and further
validated through testing in real-time environment.

1. Introduction
1.1. General
The construction revolution of today has made the
contractors to equip their construction so as to perform the
highest output with minimum construction cost. In order to
have highest output, parameters like accuracy, precision,
quality, and cycle time have to be optimized. This is possible
either by having skilled manpower or by automating the
system [1].
With the constant increase in the demand of construction,
contractors are forced to increase their construction and also
the quality of the construction to remain in the competitive
market. The construction industry in most countries amounts
to 10–20% of the GNP [2], making it the largest economic
employing sector. It is still labour dependent and most of the
work involved is repetitive. The growth of any country is
dependent on the construction industry; hence, it is of prime
economic significance to many industrial sectors. Intense
competition, shortage of skilled labour, and technological
advances are forcing rapid changes in the construction
industry, thus encouraging its automation.
The construction of buildings, apartments, complex, shops,
and homes are basic requirements of human being. In this
construction area, plastering is necessary for decorating the
wall. Plastering work or plastering refers to the construction
or ornamentation done with plaster [3], such as a layer of
plaster on an interior wall or plaster decorative mouldings on

ceilings or walls. The tools and materials for this include
trowels, floats, hammers, screeds, a hawk, scratching tools,
utility knives, laths, lath nails, lime, sand, plaster of Paris, a
variety of cements, and various ingredients to form colour
washes.
1.2. Objective
Automation is one in every of the numerous and evolving
disciplines among all technologies. Our aim is to render the
plaster on the walls mechanically. This concept aims at
reducing the work of a trained worker. It is possible,
light-weight, cheap and easy structure scrutiny to the present
machine. This innovative method keeps up with the
ever-changing world of building automation.
It is used to reduce human work, especially the work of
plasterers.
It is the machine, instead of handmade in construction
plastering area.
Very easy and simple to operate.
It is inexpensive compare with the traditional method.
Simple structure, light weight, small cubage, and easy
to operate.
Saving more than 20% raw material (cement and sand).
2. Literature Review
In general, the growth of a country is mainly dependent on
the infrastructure, agriculture, and industry. Hence the
constructional sector is of prime economic significance to
many countries. In most countries, 10–20% of the GNP is
for the construction industries [2], thereby making it one of
the largest economic employment sectors. Plastering is
construction or ornamentation work done with plasters or
