joint repair
Perdure EJF
Perdure EJF is a 100% solids flexible epoxy joint filler used to protect saw-cut joints in concrete slabs on grade or repair existing damaged joints. Perdure EJF absorbs the impact and shock of heavy loads and steel wheeled traffic, preventing erosion of control joint edges.
ADVANTAGES
- Easy 1 to 1 mixing ratio
- Ultimate elongation of 100%
- Low odor during application and cure — can be used in occupied facilities
- Cures on damp/wet surfaces
- USDA approved
