SCM-ZP is a polymer modified self-leveling repair mortar which is made of special cement, quartz sand, crack-bridging fiber, polymer glue powder and a variety of admixtures. It has good adhesion to old and new concrete substrate. It has the advantages of flowability, cracking resistance, wear resistance, oil resistance, high strength and high adhesion. It can be widely used for the repairing need such as hydraulic, harbor, highway, airport runway, bridge, industrial floor and parking lot etc.
Recommended Application Area:
1. Use to repair defects, damaged, and uneven areas of concrete or mortar surface
2. Specially suitable for the fast repair of high express way, road and airfield runway
3. Can be used for fast repair of concrete floor damage
4. It is not recommended to be directly applied on old organic waterproofing layer.
