Preparation for  
Epoxy Coating
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.
