Hydrated Lime (10kg)

Hydrated lime is a concreting and masonry additive used to improve the adhesion, flexibility, and workability of cement-based mixes. It also has a range of gardening applications, including helping to raise and balance soil pH. It is commonly used for:

• Bricklaying mortar (to improve workability)
• Rendering and plastering mixes
• Soil conditioning and pH adjustment
• Whitewashing and surface treatments
• Stabilising soil in landscaping and construction

Step 1: For a general-purpose mortar, blend 1 part cement, 1 part hydrated lime, and 1 part sand by volume until evenly combined.

Step 2: Gradually add clean drinking water and mix until you achieve a smooth, workable consistency. Using clean water helps produce a consistent mortar mix and avoids introducing impurities.

Step 3: Apply the mortar using a trowel and complete your bricklaying or masonry project.

Hydrated lime is an additive used in cement mixes—it is not a cement product itself like Builders Cement. Adding hydrated lime improves the flexibility, workability, and water retention of mortar, making it easier to apply while helping achieve a smoother finish.

When handling hydrated lime, we recommend wearing appropriate personal protective equipment. Hydrated lime is a fine powder that can easily become airborne and may irritate your eyes, skin, and respiratory system. For safe handling, wear safety glasses, gloves, and a dust mask, and avoid breathing in the dust.
