REPAIRBOUND is water based dispersion of high non
re-emulsifiable, high solids multipurpose acrylic and
versatate polymers in a special formulation designed
for concrete and strength of all commonly used mortars.
It is a high quality saponification resistant liquid
which improves the physical properties of Portland cement
and resistance to ultraviolet degradation, heat and
most common chemicals.

he mortar for above test was prepared
as follows:
Cement : 50 kg ; Quartz Sand (30/80 mesh) : 150 kg ;
Repair bond : 10 kg ; Water : 10 kg
Fields of Application :-
* Bonding Slurry between
old and fresh concrete/mortar
* Polymer Modified Cemetitious Mortar for Structural
Repairs
* Water resistance polymer based coatings
* Polymer based Injection Grouts
* Crack resistant Screes
Properties : - Repair bound Imparts
following properties :
* More economical than
epoxy mortars
* Non-toxic can be used with potable water
* Imparts excellent bonding to between existing
concrete / mortar surface and fresh concrete / mortar
* Reduces Shrinkage of mortar
* Reduces permeability of mortar
* Coefficient of expansion corresponds to that
of the unmodified mortar / concrete. The modulus mortar
is improved in terms of flexibility
thus avoiding stress in the repair systems
* Increased chemical resistance
Instruction For Use :-
Clean the base thoroughly
by wire brush and remove the loose material, dust, grease,
oil or other foreign particles. Clean the surface then
by water to remove all dust and saturate the base. Whenever
the substrate is hollow chip of till sound base is reached.
