Overview
KingSeal EP50 is a 100% solids, two-component, self- levelling semi-flexible control joint filler and crack repair material. KingSeal EP50 is a chemical curing joint filler, with a 1:1 mixing ratio by volume, giving it ideal characteristics for ease of application in control (saw cut) joints.
Applications
- For contraction/control joints that are saw cut or preformed
- To fill joints in industrial floors exposed to hard wheeled traffic
- Repairing concrete slabs that have experienced random cracking due to shrinkage
Advantages
- Pourable consistency
- Prevents deterioration of joint edges
- Shock absorbent and durable, withstands wheel traffic and heavy loads
- Excellent adhesive properties, requires no primer
- Semi-flexible, allows for moderate joint movement
- Remains semi-flexible, does not harden with age
- STANDARDS Conforms to the requirements of ACI 302.1R (Joint Materials)
