Features
Complies with Green Star requirements
It facilitates moisture retention in the concrete giving maximum strength and durability.
Based on a fine particle bitumen emulsion to give a tenacious, vapour proof bond to the substrate.
Certified curing compound to AS3799:1998.
Non-hazardous – no VOC
Quick drying and low odour
Preparation
