POLYCRETE is available in two different grades
- POLYCRETE A for high early strength where only a limited time is available for carrying out repairs.
- POLYCRETE B for normal repairs where high strengths is required but time is not a constrain
USES
- Suitable for repairs of structural slabs, columns and beams
- Repair of structures in distress, leaky water tanks, machine foundations etc.
- Can be used for grouting, lining etc.
- Emergency repairs.
ADVANTAGES
- In fresh state : cohesive, flowing and self levelling.
- In hardened state : non-shrink, good bond, compact and dense.
- Forms good bond with old concrete.
- Provides excellent finished surface in contact with the formwork

INSTRUCTIONS FOR USE
- Use 12.5% water by weight of POLYCRETE.
- Mix thoroughly in a bucket using mechanical stirrer until it forms a mix of uniform and flowable consistency.
- Normally 2 to 3 minutes of mixing is adequate. The mix is ready for use.
- Mix only as much quantity as can be consumed in about twenty to thirty minutes.
- Curing for all practical purposes should begin within 4 to 6 hours after poring POLYCRETE A.
- Use ice cold water in hot weather.
CURING
For most practical purposes, cure with water for 4 to 6 days.
PACKING
25 kg bag.
STORAGE AND SHELF LIFE
It has a shelf life of 3 months when stored in original packing in a cool, dry place. Precaution to be taken during storage so as to avoid contact with water and moisture. |
