Sand blasting is a surface cleaning process that uses compressed air to accelerate an abrasive material like sand against a surface. It can be used to remove paint, rust, and contaminants from metals, concrete, and other surfaces. The process involves little machinery, works quickly, and the abrasive materials aggressively remove deposits. However, proper safety precautions must be taken like wearing goggles, gloves, and a mask to protect from inhaling particles.

2. •Sand blast cleaning, is a surface
treatment process widely used in a variety of
different industries with many diverse purposes.
Sand blasting is the process by which an abrasive
media is accelerated through a blasting nozzle by
means of compressed air.

3.  As we are acquainted with different cleaning
procedures adopted to clean different surfaces. Sand
blasting is one of such cleansing process which makes
the use of light particles as propellants to project it on
the required surface. It makes use of different abrasive
materials as a part of its cleaning procedure. This
process is mainly preferred by the industries and the
construction firms to get rid of the unwanted particles
from the surface. It can be used to clean the surface,
remove the paint, get rid of the rusts, and etch the
surface to provide a shinier look.

5.  Removal of rust spots from the metal is one of the primary use of
sand blasting.
 Paint removal from homes and commercial offices is something
else the sand blasting process can be used for.

7. • Quick removal of contaminants: This process helps in quick
removal of the deposits of the contaminants on different
surfaces.
• Less machinery involved: This process does not make use of
complex machineries.
• Abrasive action: The materials which are used in the projection
are highly abrasive and have an aggressive action on the
surfaces.
• Fit for tough surfaces like concrete: The powerful action of the
process can remove deposits even from tough surfaces like
concrete.

8.  It is important to be aware of the necessary safety precautions that
need to be put into place before home or industrial sandblasting
can take place. Take note of the following:
 Wear safety goggles to protect your eyes;
 Make use of protective gloves;
 Ensure that you wear a mask to avoid inhaling the
 tiny particles of debris, and
 To avoid a big clean-up, wear old clothes oroveralls.
