DESCRIPTION:
It is a surface hardening product that
cement based, corundum aggregate, high
surface abrasion resistance, special
chemical additive, ready-to use, applied in a
powder form by sprinkling.
ADVANTAGES:
It has much higher strength than concrete
surfaces.
The hardness grade is high.
Retarding the surface dusting.
Provides a smooth and homogeny
appearance.
Low permeability.
Has natural decorative appearance.
Applied easy and practical.
It is durable to vehicle traffics,
Easy and fast prepare.
USAGE AREAS:
Indoors and outdoors,
To create decorative anti-corrosive coating
for industrial building floors,
To create a ground with high wear
resistance in areas exposed to vehicle
traffic,
Factory, warehouse, heliport, underground
passages,
In all mineral based floor covering areas
such as parking lot, school, shopping
center, metro stations,
It is used to strengthen the surfaces of
bearing concrete and screeds.
The surface hardener application is to
increase the abrasion, dusting and impact
strength of the selected concrete on the
concrete surface.

***These values were obtained as a result
of laboratory tests, just contain finished
applications according to drying time
performance. Due to differences in
temperature and humidity values in the
construction site, the values may change.
Surface Preparation:
The concrete to be cast must be at least
C25 quality.
All precautions should be taken to prevent
concrete from cracking
(Mesh steel, Fiber fiber additive, steel wire
additive etc.).
Concrete must be at least 7 cm thick.
Pay attention to water cement ratio should
not be over 0.45
Preparation Of The Mixture:
The product is ready for use, after opening
the bag, transfer it to a clean bucket.
Then the application starts.
Application:
Before starting HARD-C – 702, the concrete
surface should be smoothened with a
wooden trowel or gauge.
Since the timing may vary according to
weather conditions, the application can be
done when 0.5 – 1.5 cm footprint remains
after hardening.
Concrete should lose its water, but it should
not dry out completely.
Apply 5-10 cm wide product in order to
increase the strength at the main joints.
2/3 of the product is applied by sprinkling on
the surface to cover the whole surface.
The product should not be sprinkled from a
far distance. In these and similar
applications, the product may separate into
particles and the manufacturing of the
desired quality may not be possible.
When the product absorbs the water
sufficiently (color changes), it is smoothed
by trowel or wooden trowel.
The remaining 1/3 of the product should be
sprinkled on the surface as in the first
application and the application should be
repeated.
After the tray polishing, start doing slicker in
order to have glossy surface.
If the joint is going to be cut, the concrete
should be expected to reach sufficient
hardness.
After the application, the surface should be
covered with DAYMAN AC-CURE-710 or
DAYMAN P-CURE-711 in order to prevent
the concrete from a shrinkage crack
because of not discharged water and to
arrive suitable hardness.
