CH I and CH III Hydrated Lime:

Suitable for producing mortar for wall setting and coating, providing mortar consistency, sand incorporation capabilities, bonding, water resistance, tensile strength, homogeneity, as well as offering good esthetics and finish.

More accuracy regarding carbon dioxide (CO2) presence is what differentiates CHI lime from CH III. By technical standards, CH III lime may contain up to 13% of CO2, whereas the CH I has a 5% limit.

It is recommended to leave CH I lime resting for a 24 hour period after the intermediate mortar production (mortar without cement addition).
