Packaging & Shelf Life
Refractory cement is available palletized in 25kg bags, or 50kg bags. super sacks.
Refractory cement packaging is designed to protect it from humidity. However, as with all hydraulic binders, it is recommended that Refractory cement not be placed outdoors or in direct contact with the ground. When correctly stored in dry conditions, the properties of Refractory cement will remain within specification limit for at least 6 months. In most cases, its properties will be retained for over a year.
