When one enters an
office, home or warehouse, one of the major features that capture attention is
the floor. A well-polished floor can be a very welcoming and calming sight.
As much as concrete
is hard, it can also be polished to give it a shine and sophisticated look. It
is popular in schools, retail malls, warehouses, offices and many public
spaces.
To get that shiny
surface, it needs specialized equipment
do that particular job. The equipment
used is called a concrete grinder. They
are usually used to grind down the surface of the concrete using a combination
of diamond abrasives and metal bond. The floor is
also treated with a densifier. Resin bond abrasives are also used to
achieve the desired smoothness and shine.
Concrete diamond
abrasives come in different grits from a high of 3000 grit to a minimum of
16grit.To get the best result use the highest amount of grit 3000.For a floor
to be considered polished, it has to reach a grit of above 400. The finished
work is usually measured by grade and finish. The higher the finish, the
shinier the polish and the higher the grade comes out to be, it tends to create
larger the aggregates.
So what are the steps of polishing a concrete floor?
a) Sweep clean the concrete and
evaluate the hardness of the concrete by using Mohs
concrete.
b) Check for any cracks and
repair if found any.
c) Start the initial grinding
process.
d) After the initial grinding,
apply the liquid hardener on the concrete. This
hardens the surface and protects against water penetration and staining.
e) Continue to polish moving to
the next higher grit level.
f) Protect your polish by applying a stain-guard product.
When done properly, the concrete shines and looks chic
and sophisticated.

The graycolor looks too much industrial to give it
a touch of personal taste polished concrete can be dyed or stained this
enhances the look of the concrete.
Polished concrete can
be retrofitted by adding another 50 mm thick concrete or by sanding the
existing floor so that it can be hardened and polished. Another slab can also
be added then polishing can be done.
When compared to the
other forms of flooring, such as tiling, wooden, vinyl or linoleum concrete
polishing is observed to be less expensive.
Concrete polishing is
becoming popular, and as much as we see it being in warehouses and retail
spaces, it isis now time we start embracing
it in our homes also.
