Surface Preparation for Epoxy Coating
3
Even though it is obvious to clean and prepare
the floor before getting epoxy coating, surface
preparation is key to long-term success of epoxy
flooring project. Is there anything heart
breaking for a person to discover that his epoxy
floor is chipping or breaking just in few weeks
after completing it? If this is happening to your
floors, then the culprit is the poor surface
preparation. It means the substrate had not been
properly grounded, cleaned, and prepared well to
be able to bind the epoxy. What constitutes
surface preparation? Which method is the
best? This are the questions you might be seeking
answers for. In this blog, you will get answer
to the questions. Just keep reading! There are
several levels of surface preparation as per
mechanical intensity. Some methods such as
sanding is light and would barely scratch the
surface. Other methods such as scarifying can be
intense and deep.

Sanding
This is the lightest form of surface preparation.
This is done with the help of angle grinder or
even a light floor sander. Sanding paper of
varying grit is used for sanding which is
attached to the disc. Such surface preparation is
used either for re- coating, or for applying
light paint. Even if you use a rough, low grit
sandpaper, the surface scratch will be less.

Stone Grinding
Stone grinding machines were used before diamond
grinders came in the market. Moreover, epoxy
applicators are not using the stone grinders
these days. This is a heavy floor grinder which
has stone tools fastened to the bottom. This
works well for a soft concrete surface but it
does not grind well on a hard concrete surface
or even epoxy surface.

Diamond Grinders
These are versatile as these allow easy switching
out of diamonds. These can handle almost all
types of floors right from soft cement to hard
concrete. These can strip old paint layers and
also clean out oily patches from the
floor. Diamond grinders leave a deep and harsh
scratch profile of the floor which enables
better bonding of the primer to the floor. If
you are dealing with a messy and a contaminated
patch on the floor surface, little bit of
persistent diamond grinding is enough to for a
clean floor.

Shot-Blasting
This method is aggressive when compared to
grinding. It leaves a nice deep profile which
makes the bonding conditions for high-build
flooring systems like 3mm and over quite
perfect. However, shot blasting needs a good
quality concrete to work properly. If you will
try shot-blasting a weak substrate, there are
chances that you will end up damaging the
substrate.

Scarifying
This is the final solution or say the last
resort. Even though it is aggressive, this
method can save the day. To conclude, we would
say that, thicker the thicker the system that is
to be applied to the floor, the deeper the
preparation is needed. If you scarify a surface,
you would require a thick coating to cover the
surface. A thin epoxy coat will not be able to
fully cover the heavy scarred surface
profile. Epoxy flooring contractors in Melbourne
definitely prepare the floor first and then
start the coating process. However, if you
choose to do it all by yourself, you may not be
able to do it as perfectly as it is needed
before starting the epoxy coating process. So, if
