SBR Mortar


We Perma Construction Aid, Perma Bond SBR, which is an aqueous emulsion of Styrene Butadiene Copolymer latex. It is specially formulated to be use with cement. SBR modifies the property of cement in mortars and in concrete to make them perform better. Our products is useful in terms of water proofing, repair, corrosion inhibition, bonding, durability and wear resistance. We ensure that our SBR Motor of genuine quality for the purpose of construction works etc.

1) Corrosion protection of steel.
2) Floor screed and topping.
3) Concrete and floor screed repairs.
4) Water proofing and tanking of basements.

Water resistant, excellent adhesion to concrete, steel, brick, stones, compatible with cement. High compressive, tensile and flexural strength. Resistant to ingress of salts, mineral oils etc. Non toxic. Suitable for use in potable water tanks. Excellent corrosion protection. Economical when compared with epoxy mortars.


A) Method:
1) On a cleaned and prepared wet surface apply Perma Bond SBR bonding slurry.
2) Apply Perma Bond SBR modified mortar by float or trowel to form an uniform smooth surface. Bonding slurry sets very fast hence modified mortar application should be fast and immediately after application of bonding slurry.
3) Moist cure for 24 hours and then allow it to dry off.

B) Preparation:
   Bonding Slurry = Cement + SBR
                1      +     1

NOTE: Applied bonding slurry sets very fast. 1 LTR Perma Bond SBR with 1 kg of cement gives a slurry which covers 25 to 30 sq./ft.

Cement 5 kg
Zone II Sand 13 kg
Perma Bond SBR 1 Litre
Water 0.7 Litres
Yield 6.5 Litres

1) This MORTAR looks very dry. No further addition of SBR or water to be added.
2) Dosage of SBR can be varied between 5 ltrs to 15 ltrs. per 50 kg bag of cement depending upon application and severity of problem



1)  Corrosion Repairs of Beams, Columns and Slabs:
a) Remove the cover concrete and cutback to the sound concrete zone. Remove all the rust from the reinforcement by mechanical means.
b) Apply one coat of SBR bonding slurry on the reinforcement and the surrounding concrete  surface.
c) When the bonding slurry is still tacky apply  modified mortar by pressing in position. Modified mortar can be applied upto a thickness  of 20 mm. For building up the thickness leave the first layer to dry overnight and apply second layer with one more coat of bonding slurry.
d) Moist cure for 24 hours and allow it to dry off.

2) Industrial Floor or Floor Duct Nosing Repair:
a) Cutback to sound concrete surface and make the surface wet.
b) Apply the bonding slurry and when it is still wet apply the SBR modified mortar.
c) Feather edge to match the original floor level. In case of nosing carefully build up the edge and give a smooth finish.
d) Moist cure for 24 hours and allow it to dry off.

3) Bonding old Concrete to New Concrete:
a) Vertical Joint: Apply SBR bonding slurry on the prepared wet old concrete vertical surface and pour the concrete.
b) Horizontal joint: Pour and spread SB bonding slurry on the wet old concrete surface to a thickness of 3.5 mm and pour fresh concrete.

4) Tile Ove Tile:
a) Apply SBR bonding slurry to the existing mosaic or
ceramic floor and immediately spread cement paste or
cement sand mortar or tile adhesive over it.
b) Apply SBR bonding slurry to back of the tile and fix it in position.
