POLYABRES

POLYABRES is a ready to use ‘Dry Shake’ type product and provides abrasion resisting surfaces of floors etc. Constituted of synthetic or natural aggregates, it improves the long-term wear resistance of surfaces like floors, treads of staircases, garden paths or any area that has to withstand abrasion. It also provides improved slip-resistance.

POLYABRES is formulated out of select cementitious binder, with added polymeric property enhancers and tested aggregates with proven hardness. Applied on concrete surfaces, it provides good wear and good abrasion resistant properties.


Abrasion Resistance

Abrasion Resistance is a property of concrete which depends on the type of aggregates. The harder the aggregates, greater is the abrasion resistance. For convenience Geologists have a scale of “Hardness” known as MOH’s scale. The scale is as follows:

Mineral
No.
Mineral
No.
Talc
1
Feldspav
6
Gypsum
2
Quartz
7
Calcite
3
Garnet
8
Fluorspar
4
Corundum
9
Apatite
5
Diamond
10

Although the scale is based on minerals, the hardness of rocks can be judged relatively by comparing its scratch resistance level vis-à-vis a mineral. Granite has a hardness that can range from 5 to 7 depending on its constitution. Naturally occurring minerals are used as abrasives but nowdays many synthetic materials are made to match the hardness of minerals above 8. Such materials are used as abrasives and can include oxides of alumina, silicon carbide etc.


Advantages

POLYABRES when incorporated onto concrete surfaces results in the following properties of the surface.

·        Excellent abrasion resistance, hard wearing

·        Non-slip and non-skid, inspite of oil spillage

·        Suitable for interior and exterior use

·        Good impact resistance

·        Harmless to humans

·        Non-rusting

·        Resistant to mineral oils

·        Non-combustible

·        Waterproof and water resistant

·        Improves service life


Uses

·        Factory floors

·        Storage areas

·        Garages

·        Railways station platforms

·        Public areas subject to large people movement

·        Civil structures – Dams, spillways etc.

·        Both old and new floors


Instruction for use

POLYABRES is simple to use and requires to be applied on fresh concrete only. In case of old floors, a levelling screed of cement mortar 25 mm thick (average) has to be first provided, as per normal practice. (This screed has to be bonded to the base concrete)

The time to apply POLYABRES is when the base concrete or screed has set and any bleeding has stopped and the fresh concrete surface is hard to allow light foot traffic.

At this stage, half the total quantity of POLYABRES should be evenly spread on the concrete surface. This can be done by taking some quantity on a sieve of 3 mm opening covered with a brown paper having 10 mm punched holes. Once the material becomes uniformly dark by the imbibition of water, then it can be floated by trowels.

Soon after floating the balance POLYABRES should be spread at right angles to the first application and similarly floated. Subsequently power trowels can be used for final finish. Proper curing is essential. Foot traffic may permitted after 24 hours & other traffic after one week.


Application Quantity

·        Dry shake application 1 kg per square meter

·        Mixed with topping

Heavy Duty
6 – 9 kg/m2
Medium Duty
4 – 6 kg/m2
Light Duty
2.5 – 3.5 kg/m2

Note:

·   The material can be mixed in the mixer along with the floor topping and finished.

·  For coloured floors POLYBRES in colours can supplied. Check with manufacturer.


Properties

The abrasion resistance of floors treated with POLYBRES may be evaluated as per ASTM C 418 or C 779. It is seen that the wear compared to control will be very negligible.

The aggregates in POLYBRES have a hardness of around 9.
