2. This guide is a summary of the steps required to
coat a floor with epoxy floor paints.
The step by step guide describes the necessary
procedure for applying one coat of primer and two
coats of epoxy paint (roller applied)
Such floors are suitable for light and medium wear
and tear, perfect for garages and storage rooms.
6. Preparation of the substrate is necessary in order
to ensure adhesion between the epoxy product
and the substrate.
Suitable methods are sanding or diamond-
grinding. Any surfaces that have been
contaminated with oils may also require chemical
cleaning.
1. Prepare the Surface
9. Improper cleaning can lead to poor bonding of the
coat to the concrete substrate
Also various particles of dust and dirt may end up
being trapped within the coat thus leaving an
ugly looking surface with spots
2. Clean the floor
10. Use an industrial vacuum that picks up even small
dust particles.
The floor must be cleaned of all dusts and residues
before starting to prime. The less dust on the
surface the less primer you will need.
2. Clean the floor
13. Prime the floor with a suitable epoxy primer.
Priming will give your floor a longer life and
better adhesion to the substrate. Priming will seal
the substrate thus reducing the risks of bubbles
and gases.
3. Prime the floor
16. Fill all cracks, holes etc with epoxy grout. (This
step can also take place before priming if you
prefer)
For thin cracks it may be necessary to slice them
with a diamond cutter before filling in order to
improve the anchoring of the grout.
4. Filling and Grouting
18. Mixing of the A and B
components
5. Applying the first coat
19. Pay special attention to the mixing of the two
components.
Use an electrical mixer and mix the components for
at least for two minutes. Don’t skimp on the
mixing! This step is very important. Poor mixing
will lead to a tacky floor.
5. Applying the first coat
20. Apply the product with a roller. Use a good quality
roller, as poor quality rollers may start to shed.
You should be able to re-coat after 24 hours.
5. Applying the first coat
22. After the 1st coat has cured you may notice various
problems that have appeared on the surface such
as cracks, holes etc.
Make sure that these are sealed-filled before
starting the next coat. You may also need to sand
some uneven surfaces that appeared after the first
coat. If necessary wait an extra dry for the grout to
dry before re-coating.
6. Applying the 2nd final coat
23. When applying the 2nd coat remember to follow
the same mixing instructions as for 1st coat.
Mix the product properly, and use a proper high
quality roller
6. Applying the 2nd final coat
24. 6. Applying the 2nd final coat
This is how a
completed two-
coat epoxy floor
should look like
