Water Resistant Additive

DESCRIPTION

We at Perma Construction Aid, offers good range of Perma Bond-AR, which is an aqueous emulsion of Acrylic co polymer. It is specially formulated for use with cement. Perma Bond-AR modifies the property of cement in mortars and in concrete to make them perform better. We ensure that our Water Resistant Additive of genuine quality for the purpose of construction works etc.


PRIMARY USES

  • Corrosion protection of steel.
  • Repairs of structural members.
  • Repairs of industrial floors.
  • Waters proofing of basements and tanks by tanking.
  • Repairs to marine structures.


ADVANTAGES
Perma Bond-AR is water resistant and has excellent adhesion to concrete, steel, brick, stones and is compatible with cement. Perma Bond-AR modified mortars and concrete show higher compressive, tensile and flexural strengths. Perma Bond-AR mortar makes concrete resistant to ingress of salt, mineral oils etc. The product is non toxic, hence suitable for use in potable water tanks and food storage tanks.


PREPARATION
For various applications Perma Bond-AR is used in the form of bonding slurry and as an additive in the modified mortar.


Bonding Slurry
It is obtained by mixing one volume of Perma Bond AR with one and half volume of cement. This bonding slurry is applied immediately within twenty minutes of preparation.

Modified Mortar

OPC 50 Kgs
Zone II Sand 150 Kgs
Perma Bond-AR 10 to 15 Litres
Water 10 to 15 Litres
Yield 0.1 m3 or 100 Litres

 

Dosage
5 to 15 ltrs. per 50 kg bag of cement depending upon application and severity of problem.


DIRECTIONS FOR USE
On a cleaned and prepared wet surface apply
Perma Bond-AR slurry by brush. When the Perma Boand-AR slurry is still green and tacky apply modified mortar and trowel it to form a smooth and even surface. Care should be taken to apply modified mortar fast after application of bonding slurry as the bonding slurry has a tendency to dry out fast in hot weather.


TYPICAL APPLICATIONS

1. CORROSION REPAIR OF BEAMS, COLUMNS AND SLABS
a)  Remove the cover concrete and cut back to the sound concrete zone. Remove all rust from the reinforcement by mechanical means. Apply one coat of "Perma Rust
Remover" by brush on the  steel and leave it overnight.
b) Next day apply one coat of Perma Bond-AR bonding
slurry.
c) When the bonding slurry is still tacky apply Perma Bond-AR modified mortar.
d) Moisture cure for 24 hours and allow it to dry off.

2. REPAIRING INDUSTRIAL FLOOR and FLOOR  DUCT NOSING.
a)  Cut back to sound concrete and make the surface wet.
b)  Apply one coat of Perma Bond-AR bonding slurry. When the bonding coat is still tacky apply Perma Bond-AR modified mortar.
c) In case of floor duct nosing carefully build up in layers to form the edges.
d) Carefully finished it to match with the original surface.
e) Moisture cure for 24 hours and allow it to dry off.
