Method of use For Structural Rehabilitation and Repair
Step-1
Clean the reinforcements with wire brush to remove loose scales.
Step-2
Apply Jet of water to remove loose particle, dust etc.
Step-3
Mix 1 port of 01 cement + 1 part of RHEOBOND-SBR uniformly make point consistency and apply on reinforcement and allow it to dry for 2-3 hours.
Step-4
Bond Coot Make slurry with cement & SBR where SBR modified mortar is to be applied
Step-5
Polymer Modified Mortar Mix cement 50KG + Zone II sand 150 KG + RHEOBOND-SBR 10Ltr. + water 5 to 7 Ur. Apply above mortar over bond coot.
Storage
RHEOBOND-SBR has a shelf life of atleast 1 year if stored in unopened container out of direct sunlight. Handling Precautions Avoid contact with skin and eyes wash off affected skin with soap and water; use gloves for protection.
