Hydrated Lime is ideal for enhancing bond strength and workability in cement mortars. Combine lime, cement and sand in correct proportions on a non-porous surface. Large jobs will require a concrete mixer. Add drinkable water gradually and mix thoroughly. Use enough water to make a workable mix. Apply the mix with a trowel. Hydrated Lime should be stored in a cool protected place away from moisture, strong oxidants or acids and to minimize dust emissions. Storage in steel or concrete bins and silos, or plastic lined bags, is appropriate.
