A water-based bonding agent for cementitious mixtures, specially formulated to enhance bonding properties as well as improve mechanical strengths of cementitious mixes when incorporated with mixing water.

1. Bonding of new to old concrete when used as a slurry coat, floor toppings, and waterproof renders.
2. To produce a mechanical key prior to rendering of various plaster mixes on concrete, brick and block surfaces.
3. To produce a repair mortar for patching of honeycombed concrete, internally and externally.

1 Liquid Based Component

1- Where Poly Bond SBR should be used, the substrate should be sound, clean and free contamination. Dilute the bond by Adding water (1-part Poly Bond SBR to 4 parts water)

2- Using an electronic mixer, mix the diluted bond for 3 minutes. more water could be added to achieve the required workability.

3- Add the diluted bond to the cementitious mixture and mix very well once again with an electronic mixer for 3 minutes.

4- Mix very well once again with a mechanical mixer for 10 minutes.

5- Application:
a. As Admixture
b. Dilute 1-part bond SBR with 2 parts water. Mix thoroughly to obtain uniform consistency liquid. Add the diluted Bond SBR to pre-blended sand/ cement plaster, mortar, or other dry mixes. Mix for 3-4 min using mechanical mixer at low speed. Let the mixture stand for 10 min and mix again briefly to achieve homogeneous lump free mixture.
c. As Bonding Agent
d. Dilute 2 parts Poly Bond SBR with 1-part water. Mix thoroughly to obtain uniform consistency liquid. Apply using brush or spray directly onto substrate. If using hand pump, spray at a rate of 15 m2/liter. While bonding agent is still wet, follow immediately by applying plaster, render, mortars or joint tapes etc.
